We already know the results of the 2018 "Mathematical World" art competition!

The jury unanimously recognized Zuzanna Cyran from class VII of PSP No. 4 in Radomsko as the winner of this year's competition. Here is what Zuzanna writes about her work, titled "Pi all around":

"The work is made using the quilling technique and tissue paper string. Half of it represents the logo of the University of Silesia in Katowice, the logo of the department of mathematics, physics, and chemistry, and flowers. The other half represents planets and the number pi. The sphere is placed on a base in the colors of the Katowice flag".

We can only add that the jury wondered whether Zuzanna had spent the whole year on such labor-intensive work!

The entire podium this year was taken by girls, as the winner of the second prize was Magdalena Wolna from Preschool No. 73 named after Mr. Uszatek in Katowice, while the third place was awarded to Karolina Nowak from class IV a at SP No. 32 in Chorzow.

The awards will be presented during the solemn conclusion of the Pi Number Day - March 14, 2018, at 2:30 pm, in room 227 of the Institute of Mathematics of the University of Silesia in Katowice (Bankowa 14 street).

We sincerely congratulate the laureates and wish them further successes!

Już za miesiąc - 14 marca 2018 - odbędzie się XII Święto Liczby Pi!

Wszystkich gorąco zachęcamy do pomocy w organizacji tego wydarzenia. Jak co roku planujemy zorganizować dziesiątki godzin warsztatów, więc każda osoba do pomocy na wagę złota!

Co można robić? Na przykład:
- pomóc w prowadzeniu zajęć (m.in. zagadki logiczne, kasyno, Kawiarnia Szkocka, origami, zajęcia dla najmłodszych, fraktale, szyfrowanie...);
- poprowadzić wymyślone przez siebie zajęcia;
- po prostu wydawać w Kawiarni Szkockiej drobny słodki poczęstunek tym uczestnikom, którzy zgromadzą odpowiednią liczbę pi-pieniędzy;
- kierować uczestników do odpowiednich sal (dla kogoś, kto jest w Instytucie Matematyki pierwszy raz, budynek może przypominać nieco labirynt).

W sprawie szczegółowych informacji proszę o kontakt (joanna@knm.katowice.pl).

Serdecznie zapraszamy na szkolenie z programu Microsoft Excel, które odbędzie się 21 lutego o godzinie 17:00 w sali 4.14 w budynku CNTI Uniwersytetu Ekonomicznego w Katowicach. Szkolenie poprowadzą Paweł Bartela i Michał Rekus.

7 maja o godzinie 16:00 w sali 231 odbędzie się spotkanie z drem Nutefe Kwami Agbeko, który jest gościem Opiekuna KNM dra hab. Włodzimierza Fechnera.

Uwaga! Ważne!

Termin tegorocznej sesji letniej KNM-u został przeniesiony z 16.05-18.05.2014 na 9.05-11.05.2014r.

Z powodu wyjazdu do Będlewa II roku matematyki referat "O pewniku wyboru" zostaje przeniesiony.

Doktor Rafał Kucharski przygotował listę propozycji tematów, wskazówek i porad dla osob, które chciałyby wygłosić referat na zbliżającej się sesji KNM. Prezentujemy ją poniżej (należy kliknąć w "plusik"). Tematy są podzielone pod względem poziomu trudności, tak więc liczymy, że każdy znajdzie coś dla siebie. Oczywiście można też wygłosić referat spoza listy.

Sugestie do wszystkich tematów:
- definicja, określenie dziedziny (jakie funkcje przekształcamy) i przedziwdziedziny (na jakie funkcje)
- zastanowić się nad poprawnością określenia (klasa funkcji, dla których transformata istnieje)
- podstawowe własności: liniowość, mnożenie funkcji, różniczkowanie i całkowanie
- przykłady dla podstawowych funkcji: 1, indykator przedziału/zbioru, x, 1/x, x^n, e^x, ln(x), sin, cos, inne dla których transformata ma szczególnie ważną postać,
- historia powstania, motywacja, intuicja stojąca za transformacją, zastosowania, możliwe uogólnienia,
- transformata odwrotna - czy istnieje jakiś sensowny (efektywny) wzór,
- czy splot można traktować jako działanie dwuargumentowe w pewnej strukturze algebraicznej, jakie ma własności (łączność, przemienność, istnienie elementu neutralnego, odwrotnego)?

Warto zacząć od strony: en.wikipedia.org/…/List_of_transforms

Po zdecydowaniu się na temat i zaznajomieniu zagadnieniem, należy zerknąć ponownie na listę tematów i zorientować się, czy jakiś temat o numerku niższym (lub wyższym) nie nakłada się zbytnio na wybrany, ewentualnie obgadać tę kwestię z osobą, która dany temat przygotowuje.

1. Wykład wprowadzający. Całka Stjeltjesa - krótki referat (15 minut), definicja, wytłumaczenie idei + przykład. Źródło: np. Rudin - Analiza Matematyczna. Plus kilka zdań o tym jak całkuje się funkcje zespolone - argumentu rzeczywistego o wartościach zespolonych i argumentu zespolonego o wartościach zespolonych - np. Leja, Analiza zespolona.

2. Wprowadzenie do transformat. Np. Lukacs "Characteristic functions" - paragraf 1.3 "The method of integral transforms".

ŁATWE:
3. Splot Dirichleta. Funkcje arytmetyczne. Splot Dirichleta. Wzór inwersyjny Mobiusa. Źróło: Apostol - Analytic Number Theory.

4. Transformata Fenchela-Lagrange'a: Funkcje wypukłe i wklęsłe. Otoczka wypukła. Transformata i jej interpretacja geometryczna. Zastosowanie. Infimal convolution. Rockafellar - Convex Analysis.

5. Funkcja tworząca ciągu - definicja, własności (pochodna i całka), zastosowanie: rozwiązywanie rekurencji. Przykład. Czemu odpowiada dodawanie, a czemu mnożenie funkcji tworzących? Czy można traktować funkcję tworzącą jako transformatę? z-transform: en.wikipedia.org/…/Z_transform

6. Transformata Stirlinga, liczby Stirlinga I i II rodzaju: en.wikipedia.org/…/Stirling_transform

ŚREDNIO TRUDNE:
7. Splot miar. Splot funkcji. Splot gęstości prawdopodobieństwa (i interpretacja jako gęstość sumy niezależnych zmiennych losowych. Splot jako metoda wygładzania funkcji.

8. Funkcja charakterysytyczna rozkładu pradopodobieństwa. Jej zwiazek z transformatą Fouriera. Wzór na odwrócenie. Przykład funkcji charakterystycznej wektora losowego. (Lukacs)

9. Transformata Laplace'a: en.wikipedia.org/…/Laplace_transform
a) Definicja, własności.
b) Funkcja generujaca momenty.
c) Transformata Laplace'a i rozwiązywanie równań różniczkowych.
d) Odwrotna transformata Laplace'a.

TRUDNE, ALE PRZYDAŁOBY SIĘ:

10. Transformata Fouriera. Jest dużo źródeł, np. Rudin "Analiza rzeczywista i zespolona" (uwaga: książkę należy czytać ze zrozumieniem i uwagą - jest w niej sporo błędów drukarskich)

11. FFT - Fast Fourier Transform.

12. Rachunek operatorów Heaviside'a - Mikusińskiego.
Artykuł o Mikusińskim - rachunek operatorów - splot jako mnożenie.

Dear all,

I would like to thank once more to all of you, who took part in organisation of Pi Days. Thank you for giving the lectures, organising workshops, preparing Pi-Macierzator, decorating and cleaning...

Serdecznie zapraszamy wszystkich zainteresowanych na warsztaty komputerowe dotyczące platformy Sage. Poprowadzi je dr Michał Trzęsiok. Warsztaty odbędą się 28.03.2014 o godz. 16.00. Numer sali podamy wkrótce. Na warsztatach omówione zostaną podstawowe funkcje pakietu SAGE - do udziału w nich nie jest wymagana jakakolwiek wcześniejsza wiedza. Nie trzeba przynosić ze sobą sprzętu komputerowego; dr Michał Trzęsiok przywiezie ze sobą 20 netbooków. Zapraszamy!

It's today! We would like to remind, that today and tommorow on Faculty of Mathematics, Physics and Chemistry US we organise Pi Day. More informations - particulary detailed harmonogram - you can find on official web page - swietopi.pl. We encourage you to take part!

Traditionally, during Pi Days we are going to publish special issue of [Macierzator]. It will be adressed mainly to high school-age students, also those, who just begin their adventure in math, or even were never intrested in it. We seek for authors of articles, they can pertain to intresting exercises, logic puzzles, famous mathematicians... It's crushial, that articles shoud be matched to knowledge and abilities of high school students. We are waiting for artiles up to sunday, 2nd march 2014.

Rozpoczynamy przygotowania do tegorocznego Święta Pi! Tradycyjnie planujemy szereg wykładów, warsztatów, konkursów. Wszystkich członków i sypatyków Koła, którzy chcieliby włączyć się w organizację tego przedsięwzięcia, proszę o wpisanie się na wywieszoną w pokoju KNM (524) listę. Można też zgłaszać się bezpośrednio do mnie. Mile widziana każda forma aktywności: własny pomysł na nowy wykład czy warsztaty, poprowadzenie zajęć, które już były w latach ubiegłych, a także po prostu chęć pomocy - jeśli nie masz pomysłu na to, co mogłoby być Twoim zadaniem, pomożemy Ci znaleźć dla siebie coś, co da Ci satysfakcję.

Serdecznie zapraszam wszystkich tych, którzy mają pomysł, czas i chęci na wygłoszenie referatu dla licealistów - naprawdę nie ma czego się obawiać, a tematyka jest wybierana przez samego prowadzącego. Jeżeli chcesz się podzielić czymś ciekawym - nie wahaj się!

Pytanie o szczegóły można kierować do mnie: adres mailowy podany jest w moim profilu.

W piątek, 10 stycznia 2014, o godzinie 15.30, odbędzie się Wykład im.

I have prepared some notes for everyone who cannot attend the meeting tomorrow (25.10.2013); it contains sketchy description of the problem (proofs included)

Most likely the file is to be updated, here you will find the most recent version:

Wszystkie osoby, które jadą na jesienną sesję KNM UŚ, zachęcamy do wspólnej podróży pociągiem. Planujemy ruszyć z Katowic o 14.31 (ponieważ wiele osób pytało, czy możemy jechać wcześniej, zmieniliśmy godzinę z 15.58 na 14.31). Spotykamy się przy wejściu głównym na dworzec o 14.15.

Serdecznie zachęcamy członków i sympatyków koła, a także wszystkich zainteresowanych, także niezwiązanych z KNM, do wzięcia udziału w jesiennej sesji koła w Szczyrku (18-20.10.2013). Zgłoszenia przyjmujemy do piątku, 11 października 2013. Koszt wyjazdu (noclegi + wyżywienie) to 80 zł. Zawnioskowaliśmy do samorządu o dofinansowanie sesji - jeśli je otrzymamy, kwota ta zostanie zmniejszona. Składkę zbiera Marek Biedrzycki, do 14 października 2013. Do tego też dnia należy zgłosić temat referatu. Wygłoszenie go nie jest warunkiem koniecznym do wzięcia udziału w sesji, ale jest bardzo mile widziane. Więcej informacji znajduje się w odpowiedniej zakładce.

The SMS outgoing session is in three weeks - time to prepare talks! A few days ago we uploaded our suggested topics. Today we add the proposed literature, courtesy of Joanna Zwierzyńska.

The outgoing session of SMS is in (almost) a month! We encourage those who would like to give a talk but do not have an idea for a topic to check our suggested talk topics, prepared by the participants of one of the previous SMS sessions.

We'd like to inform you that the next, XXXV outgoing session of SMS US will take place on 18-20th October 2013 (Friday-Sunday) in the US resort in Szczyrk. The leading topic is "History of mathematics". Estimated cost for one person (accommodation+food) is 80-90zł; one can already register for participation. Preparing a talk very much encouraged :) See you there!

We would like to invite all members and fans of the Society for a meeting which will take place on Saturday, 22nd June 2013, at 16.00 at the Institute of Mathematics US. We are planning an evening of games and movies. People who would like to propose the movie should contact Dawid Krefta, while those interested in providing food (sandwiches?) - with me. See you there!

The ceremony of awarding the HM Rector UŚ distinctions took place on 7th June 2013. This distinction can be received only once in a lifetime for the entirety of one's activity at the University of Silesia in one of several categories (art activities, sports achievements, student life initiation). Seven such distinctions were awarded in the category "Scientific and popular scientific activities", including a special one for remarkably exceptional and numerous achievements. We are pleased to announce that this special distinction was awarded to a student of the II year of Master studies, a very active Society's member for five years now - Joanna Zwierzyńska.

At the same time a popular voting for the Student/Doctoral Student of the Year took place for the first time. As voted by the students, Joanna Zwierzyńska received this award as well. Congratulations for Ania and let this be one of many successes to come!

We are especially pleased about this recognition of Ania's achievements as her modus operandi in the Society was to always be the silent hero behind pretty much everything we've undertaken in the past five years. We are very happy that it was noticed and maybe these awards express at least part of the gratitude we as a Society owe to Ania. Congratulations!

We are changing the schedule of the Friday talks - due to Paweł Białas' illness, his SVD talk will be postponed (probably for the next academic year). Therefore the talk on 14.15 will be given by Mateusz Szymański, who will tell us about multifunctions. Everyone interested is sincerely invited!

The session is almost here. I'd like to remind everyone about giving the topics of the talks - we wouldn't want several people to prepare a talk on the same topic. It's best to give the topics directly to me, in person or by e-mail (joanna@knm.katowice.pl).

Those who have not yet paid for the session, please do so as soon as possible; it's best to contact Marek Biedrzycki about this matter.

We've uploaded some information about the upcoming outgoing session of SMS. The cost (accommodation and meals included) is 80 zł per person. We accept submissions until 24th May 2013. See you there!

We would like to invite everybody (students, lecturers, pupils) for the XXXII outgoing scientific session of the SMS US, which will take place on 14-16th June 2013. The leading topic is Game Theory.
The conference is for students, but all high school pupils are welcome as well. Giving a talk is not obligatory, but highly encouraged. More information will follow.

Jury has chosen the winners of the Pi-Day Time competition. The participants faced logical puzzles and kakuro. As it turns out, the problems may have been a little bit too difficult ;) After long discussions we award the following prizes:

I prize: Adrian Łukasik
II prize: none
Distinction award: Łukasz Dutka

We congratulate all the participants and invite them to try again next year - we promise the problems will be a little bit easier ;)

The prizes will be awarded during the prize award session on Friday, 15th March 2013. More information: swietopi.pl.

As we do every year, we would like to invite everybody to decorate the Institute of Mathematics for the Pi Days. We will be able to decorate the rooms after classes, so we meet at 4pm in 524. Of course, one can arrive a little bit later. Everyone who has their own workshop is responsible for their room - hanging posters, fractals, arranging tables, etc. Every help is welcome, also from people not participating in any activities during the Pi Days - there is a lot of work to be done...

We would like to encourage all students to participate in the Pi-DayTime competition. At http://www.swietopi.pl/download/PidejWieczorowaPora.pdf you will find various riddles and puzzles. We await your answers (with justifications) until 12th March, 23.59, at konkurs@knm.katowice.pl. Detailed rules of the competition may be found at swietopi.pl. Have fun!

The schedule for this year's Pi Days may be found on swietopi.pl. There may be some small changes and shifts; in several hours the schedule should be final.

We remind you about the competitions: the problems for Epigramat are available online now. On 6th March the problems for "Pi-Day time competition" will be published, which will have the form of various riddles, answers to which should be sent by e-mail. We encourage everybody to participate!

As is our annual tradition, aside from workshops and lectures we organise competitions on Pi Days. One of them is Epigramat, which first stage is starting right now. More information on swietopi.pl/epigramat.php. Information on more competitions will be published shortly. We encourage everybody to take part!

Everyone interested in helping organising this year's Pi Days are invited for the mathematical organisation meeting, which will take place on Thursday, 28th February 2012 at 11 am in the Society's room (524).

During the meeting we will discuss the final schedule of the mathematical part of Pi Days, we will distribute the tasks and discuss the talks and workshops. All help is welcome: if you have no idea what you could do, come to us! Surely we will find something for you in one of the workshop rooms.

As I know some of you have classes at that time, I will be in the Society's room from 10 am to 12 - if those hours are not suitable as well, e-mail me at: joanna@knm.katowice.pl.

This year's Pi Days will take place on 14-15 March 2013. Traditionally we are planning to organise a plethora of lectures, competitionos, workshops. Everyone interested in organising the Pi Days, please contact me.

It is very important to create a budget for the Pi Days - we are planning to do so in the coming days. Therefore those planning to organise workshops with financial requirements (e.g. to buy origami paper, xero or print materials etc.), please contact me as soon as possible.

We are happy to announce that Szymon Draga (currently a II year student of his Master's studies) got a recognition award in the prestigious Józef Marcinkiewicz competition for a best student mathematics paper. Jury of the competition rewarded his paper "Regularity of the graphs of injective additive functions", published last year in Aequationes Mathematicae. Congratulations to Szymon and we hope for many more scientific successes!

On Friday, 11th January 2013, the Vi Lecture in memory of prof. Andrzej Lasota will take place. Prof. dr hab. Łukasz Stettner from the Polish Academy of Sciences will give a talk entitled "Ergodicity of filtration processes - on an error for many years and attempts to correct it". The lecture will take place in the Facultyy Council room (227) at 15.30. Everyone interested is kindly invited to attend - the meeting is open for all.

Six years ago, on 28th December 2006,

Prof. zw. dr. hab. Andrzej Lasota,

one of the greatest Polish mathematicians,
a Honoris Causa doctor of the University of Silesia,
an active member of Polish Academy of Science,
an active member of Polish Academy of Arts and Sciences,
a many-year Professor of the University of Silesia,
died. Polish science suffered an irreparable loss.

We remember You, Professor!

In relation to fifth anniversary of prof. Andrzej Lasota's death, the website of SMS will have a black&white layout in the days 28-31 December 2011 and in the upper left corner His picture will be visible. A memory about the Professor is available in a special issue of Macierzator.

Good bye, Friend.




Information for those who want to say goodbye to Mikołaj.

Anyone who'd like to chip in for the flowers please contact me (e.g. at j.zwierzynska@knm.katowice.pl).

As is our annual tradition, directly before Christmas we'd like to share the wafer. We would like to invite all members of SMS, former and current, and also anybody interested to spend some time together and talk. The Christmas meeting will take place on Friday (21st December) at 15.00. All guests, also late ones, are welcome! At 16.30 Mateusz Szymański's talk on game theory will take place.

We will be in the Society's room earlier, from around 14.15 - come by earlier to help us prepare the meeting.

We are delighted that so many people took part in our contest. The solutions were accepted until yesterday; today we announce the winners.

The most difficult riddle was the Sherlock Holmes one, with only one person - Magdalena Chroboczek - giving a full and correct answer. As Magda also solved flawlessly all the other riddles, she is our winner. Congratulations!

There were many contenders for the second prize. With eight points out of nine our second award goes to Ania Jacek, to whom we also direct our sincerest congratulations!

Magda and Ania, please contact me, as your rewards (both tomes of Professor Stewart's "Cabinet of Mathematical Curosities") await :)

We'd like to announce that on 3-7th December 2012 the traiditional Christmas fundraising will take place, organised annually by the Students' Mathematical Society of US. This year our presents will be given to children from the orphanage in Piekary Śląskie (mainly adolescents). We are collecting:

- school materials;
- cosmetics;
- games;
- bathing products;
- toys.

We are encouraging everyone to participate!

In case of any questions please contact Marek Biedrzycki (m.biedrzycki@knm.katowice.pl), who coordinates the fundraising.

We've uploaded the October issue of Macierzator. From the introduction:

„[Macierzator] begins with an article on functions continuous in at least one point (of which there are surprisingly few). We welcome the new academic year with a new monthly cycle of reviews of books popularising high mathematics. We also give you the next part of the TeX corner, where we tell you how to create tables in TeX; we remind you that all the archival parts of the corner may be found at knm.katowice.pl/macierzator.php.
We encourage you to look around the [Macierzator] archives – one can not only find a plethora of interesting articles on mathematics and mathematicians, but also good advice on, for example, writing e-mails to your lecturers (Macierzator 30)."

We'd like to invite everyone to participate in the XXXIII Outgoing Session of the SMS US, which will take place on 23-25th November 2012. Our leading topic is number theory and cryptography. This year the conference will NOT take place in Szczyrk, but in Ustroń. Our estimated cost (accommodation + food) is 60 zł per person. More information to follow.

We are forwarding some information which may be interesting to you:
Everybody is invited to participate in the Global Management Challenge! GMC is the biggest business simulation in the world. Teams consisting of 3-5 people, created by students (II-V year) and company representatives) start in the competition. Each team assumes the role of the board of directors of a virtual company, and because of it is responsible for making the strategic decisions in all the areas of the company's life. The main criterion of winning in the competition is attaining the highest stock value at the virtual stock market. On 19th October the registration of student teams for the GMC Poland competition will begin.More information atwww.gmcpoland.pl.

It's my pleasure to announce that Anna Jacek became the assistant administrative president of SMS for the next two years. We wish her lots of pleasure and satisfaction from working in our board of directors - of course, she may count on our constant support and help and advice, as needed. Good luck :)

The new academic year is also a good time to change the board of directors of SMS for a fresh perspective. Since 1 October 2012 the new director of SMS is Marek Biedrzycki and his scientific assistant is Mateusz Szymański. We wish all the best to the new board and we will happily help and advise you in whatever you need. Good luck!

In last year's September nine members of the Students' Mathematical Society US took part in the summer intensive mathematical course - Analytical and Computer Assisted Methods in Mathematical Models. The ACAMiMM project is three years long, but unfortunately for us, the participants from the previous year, every student may take part in it only once.

This year the intensive course is held in Germany, Schwarzwald, in the city Freudenstadt, from 9th to 23rd September 2012. Its participants will be able to get even 6 ECTS points. More information may be found on our "Other outings" subpage.

We would like to encourage all students from all years to participate - last year we had some participants from the first year and they did great. All questions may be sent to my e-mail address (j.zwierzynska@knm.katowice.pl); applications may be also sent to this address. The deadline for applications is 8th July 2012. The results of the recruitment process will be announced shortly after. It's worth it!

We would like to invite all historical and current members of the Society for this academic year's last meeting of the members-reanimators of SMS and not only them, which will take place on Wednesday, 20th June 2012, at 16.30. We are meeting, as usual, in room 228 of the Institute of Mathematics of US in Katowice.

My dearest, due to the exam session approaching, this once we are changing our traditional schedule of the Szczyrk outgoing session. Instead of the classical talk day on Saturday, we will have a whole day excursion (for those eager to do so), while the talks will take place on Friday and Saturday evening.

Attention! Due to popular demand, the next lecture on Banach algebras, which was to take place tomorrow, will be moved - most probably for October; then we're planning to intensively return to this talk cycle.

We would like to invite everybody (students, lecturers, pupils) for the XXXII outgoing scientific session of the SMS US, which will take place on 1-3 June 2012. The leading topic is Algorithms. Applications are accepted up to 30th May 2012 (e.g. on the address knm@knm.katowice.pl). More information is available at the subpage "Sessions".

On next Wednesday, 23rd May 2012, the II Symposium of the Students' Mathematical Society and the Scientific Society of the Antropology of Literature US will take place. Its leading topic is "To tell the time"; the opening talk, entitled "Aspects of time in »Lalka«:, will be given by dr hab. Ryszard Koziołek. We begin at 14.00 in room 301 of the Faculty of Filology US in Katowice (Sejm Śląski Sq).

During the next week Professor Wolfgang Reichel from Karlsruhe Institute of Technology will be a guest in our Institute. Hence we planned a multitude of all kinds of events: from talks to excursions. We would like to invite all interested to participate in them. In particular we point out the Thursday talks.

The schedule can be downloaded here in pdf format, or read by clicking on the plus sign.

It is my pleasure to announce that Professor Wolfgang Reichel from Karlsruhe Institute of Technology will be our guest in the Institute of Mathematics US. Professor Reichel is an exceptional specialist in partial differential equations. He is particularly close to people from our Institute: students from the Society made their acquaintance with him during the mathematical intensive course, which took place during the last holidays; there also the idea to invite him to Katowice was born. To our pleasure, Professor Reichel accepted our invitation. Due to his visit we are planning several talks and meetings; a detailed schedule will be uploaded on the website shortly. We remember Professor Reichel's talks during the intensive course as particularly interesting, transparent and witty – therefore we encourage all interested to participate actively in the events planned for the Professor's visit even more.

Professor Reichel made us a great and incredibly kind surprise a few months back: for the cover of the first issue of [Macierzator] in this academic year we have chosen his drawing. To our joyful astonishment, Professor Reichel pasted part of the cover and described the whole situation on his official Institute website (math.kit.edu/…/~reichel/).

I would like to give my sincerest thanks here to Professor Roman Ger, Head of the Institute of Mathematics US, for his incredible kindness, invaluable help and a very supportive attitude toward the whole initiative.

We would like to wish you all restful and calm holidays - may this time period be full of joy and let you recharge your batteries.

Happy Easter!

Yesterday in Ostrava the Vojtech Jarnik international mathematical competition took place. University of Silesia was represented by three SMS' members: Szymon Draga, Konrad Jałowiecki and Paweł Zwoleński. Szymon scored the best with 21 points and a great, 12th place. Congratulations to our three brave men!

This year we will again organise our (ninth already!) Summer Camp.
As the year before, it will take place in Zakopane, most probably on 9th-15th July.
This year's leading topic is "Applications of the probability theory".
As is our tradition, we would like to spend our camp actively. Hence several mountain trips, walks around Zakopane and several talks are planned.
The exact schedule of the trip will be given after Easter.
We estimate the costs of the camp at 200 zł per person.
For more information click the plus ->

The price includes:

- accommodation: 6 nights, probably in the Burtek resort (burtek.pl, rooms with bathrooms),
- full board: 7*(breakfast+dinner in the resort)
- costs of busses, tickets to TPN, musea, etc.

The price DOES NOT include the cost to get to and out of Zakopane.

After Easter we will also include our propositions regarding the topics of talks and literature.

In custom with our tradition, we encourage every participant of the camp to give a talk (we will gladly help everyone to find a topic and prepare the talk).

As we need to book the places beforehand, please think your application through (in case of a resignation we can't guarantee a refund).

In the name of the Dean of the Faculty of Mathematics, Physics and Chemistry US, prof. dr hab. Maciej Sablik, we would like to invite everybody who took part in organisation of this year's Pi Days for its festive summation, which will take place on Wednesday, 4th April 2012, at 12 in the US Institute of Physics' cafe.

At the same time we would like to remind you that for some time already recordings from the majority of talks given during the Pi Days have been made available to the public along with a word of thanks for those who helped with organising the mathematical part.

We would like to give our sincerest thanks to all our visitors during the Pi Days - we are happy that we again were able to entertain so many of you. We would be very grateful for your opinions on the whole event and particular activities; praise is pleasant and advice allows us to develop what was not perfect. If you would like to share your opinion, please contact us (e.g. on knm@knm.katowice.pl). You can also share your comment on the appropriate webpage.

We also encourage everyone to watch and comment the pictures (to place a comment, click the plus sign in the bottom right corner of each picture). We would also be happy to publish any pictures made by you - if you would like to share them, please contact us (e.g. at knm@knm.katowice.pl).

We would like to remind everyone that there are many competitions taking place during the Pi Days - the deadlines for applications for some of them expires shortly. As is our yearly tradition we are planning the interdisciplinar Tour de Science, during which the participants will face problems from different branches of science in rooms located throughout our faculty (and to get to these rooms additional riddles will have to be solved). For those not necessarily eager to go sightseeing in the University we are planning a Pi-Crossowrd, during which the participants will have to use their mathematical knowledge (also from the history of mathematics). We also repeat the last year's hit - Who Wants to be a Pillionaire. This last competition is open to everyone - you can always join and do not need to sign up in advance.

Pi Days 2012 in just three days! All interested pupils, students, teachers and those not related to mathematics at all are sincerely invited to the Institute of Mathematics US on 14th and 15th March. We have lectures, workshops and competitions scheduled, some simpler, some harder, for those wanting to hear and for those wanting to take active part. We'll see you there!
The full schedule of the Pi Days may be found at swietopi.pl.

At swietopi.pl a nearly complete schedule of the Pi Days, held this year in the Institute of Mathematics US at 14th and 15th March 2012, has been made available. We sincerely invite everyone interested to participate in our lectures, workshops and competitions! Of course, all activities organised by SMS are as always free of charge and opened for everyone.

We sincerely invite the high school students to participate in the e-pi-graMAT competition, held annually in connection with the Pi Days in our INstitute. The competition consists of the internet part and the finals, which will take place 15th March 2012 in the Institute of Mathematics of US.

There are 10 problems from various areas of mathematics available at swietopi.pl/epigramat . Their solutions should be sent by 29th February. The results of the internet stage will be announced on 6th March 2012.

The regulations and more information about the competition may be found at swietopi.pl/epigramat.php.

We announce that on 17th February 2012 at 12:00 the PhD defense of one of the historic Society's members - msc. (for now) Michał Trzęsiok - will take place. The title of his thesis is "Support vector method in the analysis of social-economic data". We wish Michał good luck!

We are slowly finalizing the schedule of this year's Pi Days, which will traditionally take place in the middle of March. As per our yearly tradition, we've prepared a multitude of workshops and lectures - a detailed schedule will appear at swietopi.pl around 20th February. We encourage everyone to participate in the Pi Days, especially our students to participate actively: those who would like to help in the organisation, please contact us at, for example, j.zwierzynska@knm.katowice.pl. Those who would like to help but do not have an idea for their own lecture or workshops are also welcome - we need every pair of hands and we will always find something you can help us with. Of course you do not need to be a member of the Society - we are happy with every help we can get, regardless of their chosen branch of studies.

Due to winter holidays (and the exam session on the university) we've decided, that the next talk for the high school students (and not only them) will take place on 17th February 2012. Then Mikołaj Stańczyk will give a talk "Real numbers". Our next talk will take place a week later, 24th February 2012, and it will be given by Paweł Zwoleński. Both talks will, as traditional, commence at 16.15 in room 213 in the Institute of Mathematics US (Katowice, Bankowa street 14) and are of course free of charge. Everyone interested is wholeheartedly invited!

We would like to invite everyone to the I Symposium of the Scientific Society of the Antropology of Literature US and the Students' Mathematical Society US, entitled „The desire of Space. Mathema and humanitas".

Prof. Jerzy Mioduszewski, a professor of mathematics interested in topology and a history of mathematics passionate, will open the meeting with a talk "Topological space". After the talk a discussion will take place, in which dr Leszek Zwierzyński - a literary scholar, interested in, among others, interpretation, geopoetics and hermeneutics, the tutor of the Society of Antropology of Literatur US - will participate along with the members of both Societies.

The Symposium will take place on Wednesday, 18th January 2012, at 13.45 in room 554 of the Institute of Mathematics of the University of Silesia at Bankowa 14 in Katowice. Everyone is invited. Contact ->

One can contact with the organisers by e-mail (sympozjum@knm.katowice.pl) or in person: with Paweł Paszek, the president of the Scientific Society of the Antropology of Literature US, in the room 202 in the Institute of Culture Sciences of US, and with Joanna Zwierzyńska, the president of the Students' Mathematical Society US, in the room 524 in the Institute of Mathematics US.

In the last two issues of Macierzator we published two mathematical comics of a member of our Society - Ania Jacek. Many people contacted me, praising these little gems of comic-drawing art. Creating a comics is plenty of work - in Ania's case not only creative, but also technical: as she lacks a graphical tablet, Ania draws her comics by hand, scans, corrects in a graphical program using a mouse...

However, we can make it easier for her! Ania applied for funding of a graphical tablet in the project "Stypendium z wyboru" (which may be loosely translated to "Scholarship of choice"). If you like Ania's comics - vote for her! Voting closes on 22nd January 2012.

We hereby invite everyone for the Society's game evening, which will take place on Friday, 13th January 2012, after Jola Marzec's talk (so approximately at 16.00), in room 535. We encourage everybody to bring their own favorite games. See you there!

The Dean and the Committee of the Faculty of Mathematics, Physics and Chemistry of US hereby invite all interested for the V Lecture in memory of prof. Andrzej Lasota, which will take place on 13th January 2012 in room 321 of the PAN Institute of Mathematics in Warsaw. A talk "Functional analysis and nonlinear boundary problems: the legacy of Andrzej Lasota" will be given by Prof. Jean Mawhin from the Universite Catholique de Louvain. After the talk a lecture session commemorating the 80th birthday of Professor Andrzej Lasota will take place, during which talks will be given by prof. dr hab. Józef Myjak, prof. dr hab. Ryszard Rudnicki and prof. dr hab. Tomasz Szarek.

We hereby invite all interested 3rd year students of the bachelor's studies for an informal meeting regarding the bachelor's exam. The meeting will take place on 5th January 2012 at 10.15 in 524. Joanna Zwierzyńska, who passed this exam in June, will talk about the form of the exam, the rules, exemplary questions from the last two years and will generaly try to alleviate all fears connected to this exam.

On the polls that were filled by high school students during our last three meetings, we asked, among others, for the optimal length of the talks. For some it is 60 minutes, for others 90 minutes is too little. Therefore for our participants convenience (also to be able to plan their return trip), from the next meeting onwards we will provide a lecturer's estimate of the time of their talk.

Five years ago, on 28th December 2006,

Prof. zw. dr. hab. Andrzej Lasota,

one of the greatest Polish mathematicians,
a Honoris Causa doctor of the University of Silesia,
an active member of Polish Academy of Science,
an active member of Polish Academy of Arts and Sciences,
a many-year Professor of the University of Silesia,
died. Polish science suffered an irreparable loss.

We remember You, Professor!

In relation to fifth anniversary of prof. Andrzej Lasota's death, the website of SMS will have a black&white layout in the days 28-31 December 2011 and in the upper left corner His picture will be visible. A memory about the Professor is available in a special issue of Macierzator.

It is Christmas here already,
Tables full of a food mix,
Merry Christmas are wished to you -
By us and the e^x!
And when New Year's Eve is yonder,
You will count from ten or nine,
Everything will be nice and simple,
Even the graph of a cosine.

Did you know that on Christmas Eve functions talk with a human voice?

We hereby invite all members and sympathizers of the Society for this year's Christmas meeting, which will take place on Wednesday, 21st December 2011. We begin in 524 at approximately 12:15. It would be nice to bring with yourself a cake, fruit, salad, juice or other nice things - but of course it is not compulsory.

We would like to remind you, that tomorrow we will start a Christmas fund-raising.
We collect:
- toys;
- cleaning utensils;
- school & paper accessories;
- sweets.
For more information, please click ->
As is our yearly tradition, the Students' Mathematical Society of Univeristy of Silesia organises a Christmas fund-raising on the Department of Mathematics, Physics and Chemistry US. This year we collect gifts for the pupils of a Caritas common room of Saint Wojciech in Katowice.

We collect:
- toys;
- cleaning utensils;
- school & paper accessories;
- sweets.

Most probably our gifts will be the only presents the children from the hostel will get this year. Therefore we encourage everyone to participate! Containers for the gifts will be placed throughout the Deparment between 5 and 9 December 2011.

Up to now all our recordings, because of the enormous volume of the original files (approximately 4 GB for every hour of recording), have been uploaded on the Society's website in the compressed version, and hence in a much worse quality. From now we will upload both versions: the original and the compressed. We've also uploaded uncompressed versions of some talks from the last and the current academic year.

During the last-week session in Szczyrk we talked, among others, about the book "An invitation to C*-algebras" by an American mathematician William Arveson. We are sorry to announce that professor Arveson, a specialist in operator algebras theory, died 15th November 2011.

As is our yearly tradition, the Students' Mathematical Society of Univeristy of Silesia organises a Christmas fund-raising on the Department of Mathematics, Physics and Chemistry US. This year we collect gifts for the pupils of a Caritas common room of Saint Wojciech in Katowice.

Professor Wolfgang Reichel from the Karlsruhe Institute of Technology put into his webpage some information about the story behind his drawing of the convexity-sisters, which has been used at the frontpage of the last issue of [Macierzator]. It is very nice for us, so we want to share with everyone the link to professor Reichel's homepage. Thank you for everything, professor Reichel!

With incredible pleasure I announce that the Internet edition of [Macierzator]

has got ISSN 2083-9774.
Thanks to enourmous workload of the redaction during the last academic year, [Macierzator], from a niche academic paper, became a professional students' monthly mathematical paper, read all over Poland. Have you read it yet?

One year ago, on 14th October 2010 Benoit Mandelbrot, one of the greatest modern mathematicians, died in Cambridge. He was 85.

Born in Warsaw Mandelbrot was a father of fractal geometry, one of the youngest branches of mathematics. All the fractals that decorate our Institute of Mathematics during the Pi Days are fragments of the Mandelbrot set.

More about Mandelbrot may be read in the 28th issue of [Macierzator].

As the academic year already began, the time of writing lots and lots of e-mails to our lecturers is upon us; as many people asked me how should one do that, I've written a small article, published in the 30th issue of [Macierzator]. How should you begin (and why not with "welcome"!), what should you avoid, some useful advice - all this one can find in the aforementioned text. Have fun.

We hereby invite everyone interested to participate in the outgoing session of SMS in Szczyrk in 10th-13th November 2011. Our leading topic is "Motivations, intuitions, constructions".

We will be accepting applications up to 1st November 2011. Topics of the talks should be sent before 5th November 2011. Cost of the trip will be approximately 90 zł (lodging and full board included).

More information may be found at the session's subpage.

We wanted to announce the Silesian Scientists' Night, which will take place on 23rd September 2011.

The event's purpose is to popularise science among broader public, so everyone are welcome, including (maybe especially) those, who do not have much contact with science in their everyday life.

Members of the Silesian Mathematical Society of the Silesian University will prepare talks and workshops from fractals, cryptography and puzzles. A detailed schedule of these activities is available (only in Polish).

In the appropriate subpage more propositions for talks for the upcoming SMS session appeared, this time by Tomek Kania. To all his propositions a bibliography is attached. We remind you that the leading topic is "Motivations, intuitions, constructions" and its date - 10-13 November 2011. More information shortly.

Even though we have a lot of time until the fall SMS session comes around, we already have some propositions for the topics of the talks. The list will grow, incorporating topics from other branches of mathematics. We encourage everyone to send their own - best by direct contact with Joanna Zwierzyńska.

Soon the Holiday Cleaning of the Society's room will commence, so we ask all the members to take their beloved flawed plates and mugs, extremely important, but dirty and torn up notes and other strange things, because otherwise they may disappear without a trace. Those unable to appear in 524 up to 24th July and having something valuable in the room, please contact me.

We remind veryone considering mathematical studies on US, or those who already made their decision but want to ask something or get some advice that we have created a special section on our forum just for such matters.

Our Mathematical League has ended. A definite winner was a high school student - Adam Glos from the I Karol Miarka LO in Żory having over 100 points more than the next competitor. Congratulations! The main and only prize (a logic game) goes to him - it may be picked up in the room no. 524. We wanted to thank all people who sent at least one solution and we remain hoping that next year rivalry will be more fierce.

We sincerely invite all III year bachelor students for a casual meeting concerning the bachelor's exam - on Thursday, 19th May 2011, at around 13:45. During it one will get to know more from the 'student' side - Jolanta Marzec will tell about hers (and not only hers) experiences from last year and will answer all exam-related questions. The meeting will take place in the room no. 208.

We wanted to remind all the patricipants of the Toruń Summer School of Mathematics and the Young Mathematicians' Workshops of UJ that they should register to them presently. Those wanting to obtain a (at least partial) refund for them please contact me or Mateusz Jurczyński before Friday, 6th May 2011 - after this date no further refunds will be possible.

Every good thing has its end - so had it the XXX outgoing session of SMS „Patologies and paradoxes in mathematics”. The leading topic of our XXXI session will be „Motivations, intuitions and constructions in mathematics”. It will take place approximately on 10th November 2011.

Materials, photos and the report from the session will be uploaded on the webpage in a few days.

Moreover, we had a little change in our board of directors. When this academic year ends, Joanna Zwierzyńska will become the president of the Students' Mathematical Society. The rest of the board will remain unchanged (with Mateusz Jurczyński as a honorary member).

Due to financial difficulties, VU University Amsterdam plans to close the Institute of Theoretical Mathematics. Consequently, an earlier retirement awaits two mathematicians, and four more will become unemployed. There are great names among them: Dietrich Notbohm, Tilman Bauer and Rob de Jeu. This decision met with an outrage of the academical societies throughout the world. Please help spreat this information along with the address of the petition that we encourage everyone to sign.

We want to accent that this situation has a direct meaning for the students of our institute - due to the One Master Two Degrees programme a few of them goes to this university annually to obtain their master's degree there.

The Students' Mathematical Society of University of Silesia wanted to wish you all all the best, to spend the holidays among your family and to regenerate your abilities, so that you can get back to the Queen of Sciences (in appropriate time).

We remind you about charities going on on our Faculty: for many months now we in the SMS room collect plastic bottle caps. The income from the sale of them is used to pay for the treatment of nine-year old, sick on an incurable illness - cystic fibrosis - Tymek Bugla. Moreover, starting this month bottle caps are also collected for Marta Fabian - students want to help her this way in buying a new, lighter wheelchair.

We encourage everyone to participate in these actions.

From 11th to 14th April 2011 the 6th Students' Festival of Science will take place at the University of Silesia, which will open its lecture halls, libraries, workshops and laboratories. The central event of the festival will be the Knowledge Fair (14th April). At the Bankowa street in Katowice a tent city will emerge. The students will prepare multitude of attractions.

More information may be found at the event's website - www.festiwalnauki.us.edu.pl.

On 31st March in Ostrava the 21st International Vojtěch Jarník Annual Mathematical Competition for students of mathematics was held and members of SMS: Szymon Draga, Mateusz Jurczyński, Jolanta Marzec and Marek Biedrzycki participated. Szymon scored the best with 20 points which gave him a very good 14th place. Congratulations!

We hereby invite everyone interested to participate in the outgoing session of SMS in Szczyrk in 29th April - 3rd May 2011 (Friday - Tuesday). Our leading topic is "Patologies and paradoxes in mathematics".

We will be accepting applications up to 20th April 2011. Topics of the talks should be sent before 25th April 2011. Cost of the trip will be approximately 90 zł (lodging and full board included).

More information may be found at the session's subpage.

We are happy to inform that pictures and videos taken during the 5th Pi Day in the Instytute of Mathematics are now avaiable. For your convenience these have been sorted first by date, then by events. We encourage everone to browse and leave comments.

This year's VIII summer camp of the Students' Mathematical Society will take place on 1-7 July 2011 in Zakopane. Our leading topic is „Applications of the differential equations". Estimated cost is 150 zł plus travel costs. Applications will be accepted up to the end of March 2011 by Weronika Siwek and Marek Biedrzycki.

More information (along with detailed schedule of the camp) may be found at the camp's subpage.

We would like to thank all our guest for your presence during the Pi Day, for involvement in our workshops and for creating such an positive atmosphere of science and fun. Seeing you enjoing our activities gives us great satisfaction.

Also if you have taken some photos during your visit to our univeristy, please send them to j.zwierzynska@knm.katowice.pl as we will be very happy to them on our website.

The winners of our this year's competition are:

I Paweł Kubiak, Mikołaj Kopernik I LO in Katowice
II Beniamin Stecuła, SRKAK School in Chorzów
III Adam Białożyt, Maria Skłodowska-Curie VIII LO in Katowice

Congratulations! Awarding of the prizes will take place on 15th March on 16.30 in the Rialto Theatre.

We remind you that on Monday and Tuesday (14-15 March 2011) we will celebrate the Pi Days for the 5th time. We've prepared lectures, workshops, contests. A complete schedule is available at swietopi.pl. Everyone interested, not only pupils and students, is kindly invited!

We've uploaded the second (and final) part of the Jigsaws. Good luck!

We've uploaded rebuses for our annual "Mathematical Puzzles" competition. The second part (problems) will appear on 4th March 2011.

Good luck!

During this year's Pi Days the Tour de Science will be organised for the third time. It is addressed to the high school pupils and exceptional junior high school students. Eight teams consisting of three people will participate. More information ->

During the race teams will have to solve 8 problems, concerning elementary knowledge from physics, chemistry, information technology and mathematics. The problems will have the character of puzzles and rebuses popularising the four branches of science mentioned above. To solve them one would have to be able to use his knowledge and think logically. Moreover to get to each stage one would have to solve a short riddle, whose solution would be the address of next stage.
The winner of the competition will be the team which will solve all the problems and get to the finishing line in shortest time.

Detailed rules of the competition may be found at swietopi.pl. Teams may sign up by sending an application on the address bieg@knm.katowice.pl.

The beta version of the schedule for the 5th Pi-Day is now available on the swietopi.pl. Please treat as a draft, since the final version is due to appear within few days and some minor changes are very probable. (We are also working on filling the gaps in events' descriptions.) Everyone is welcome (not only pupils and teachers)!

We hereby invite high school and exceptional junior high school students to participate in the

Mathematical Puzzles & Jigsaws
contest! Participants have to solve as many as possible mathematical riddles of various types. More information here ->
1. Problems differ in difficulty, some being possible to solve by a junior high school student, some requiring knowledge from outside of the high school programme.
2. The riddles will appear on our website on 26th February 2011.
3. Solutions are to be mailed at lamiglowki@knm.katowice.pl up to 10th March 2011 inclusive. Contact data (first and family name of the participant along with the name and number of the school) should be attached.
4. Six people who will score the most points will be rewarded. In case a few people obtain the same result, they will claim the prize ex aequo. No extra time is foreseen and it does not matter, who mailed his solutions first.
5. The contest's results will appear at the website of Students Mathematical Society of University of Silesia in Katowice, en.knm.katowice.pl, on 13th March 2011.
6. The winners will receive material prizes. The awarding ceremony will take place during the Pi Days, more accurately on 15th March 2011 at 15.30 in the Rialto Cinema.
More information about Pi Days is to be found at swietopi.pl

During the conference we had the "Problems and Remarks" session which was meant for presenting some open problems and remarks concerning the subjects raised at the meeting. We have heard about some problems stemming from recent research, and also certain classical old problems were recalled. You may find precise statements of them in the attached pdf file.

We have uploaded photos from the 7th International Students' Conference on Analysis in Wisła. For your convenience, we have sorted them into various folders, firstly by date, secondly by events.
We encourage you to view and comment the photos, preferably in English.

We announce that on Friday, 14th January 2011, a Talk in memory of Professor Andrzej Lasota will be given by prof. dr hab. Lech Górniewicz. The title of the talk is

"Differential inclusions - a theory began by the Cracow school of mathematics"
The meeting will begin at 15.30 in room no. 227 of the Institute of Mathematics SU.

We encourage everyone to participate in the talk. More information may be found at the Institute of Mathematics' website.

We've received a following message from dr eng. Zbigniew Skoczylas (yup, the same one as in the book we've all read) on our official Society address:


Dear Sir or Madam,

I invite you to take part in a competition with a reward. The winner would be the person who is the first to prove my hipothesis concerning a certain property of matrices of distances between points in Rⁿ.
The hipothesis and the rules of the competition are attached. Please spread the word about the competition among other mathematicians.(...)

The reward is 1000 zł. More information ->

To Members of Students' Mathematical Societies!

Dear Sir or Madam,

I invite you to take part in a competition with a reward. The winner would be the person who is the first to prove my hipothesis concerning a certain property of matrices of distances between points in Rⁿ.
The hipothesis and the rules of the competition are attached. Please spread the word about the competition among other mathematicians.(...)

In the beginning the hipothesis was of the form:
show that for different points P₁, P₂,...,P_k, k>1, from the space R^b the following is true:

det [d_ij]≠ 0, where d_ij denotes the Euclidean distance between P_i, P_j.

When some years ago I showed the hipothesis to prof. dr hab. Czesław Ryll-Nardzewski, he proposed putting a factor (-1)^k+1 before the determinant and to substitute > for ≠.

I propose to prove the hipothesis in this version.

Kind regards,
Zbigniew Skoczylas

Politechnika Wrocławska

A pdf file with detailed information and the problem as formulated by dr Skoczylas are available on his website..

With great sorrow we announce that on 14th October 2010 Benoit Mandelbrot, one of the greatest modern mathematicians, died in Cambridge. He was 85.

The sad news were given by the New York Times.
Born in Warsaw Mandelbrot was a father of fractal geometry, one of the youngest branches of mathematics. All the fractals that decorate our Institute of Mathematics during the Pi Days are fragments of the Mandelbrot set.

The world of science suffered an irreparable loss.
More about Mandelbrot may be read in the 28th issue of [Macierzator].

On the behalf of the Organisers we hereby invite you to take part in the conference "Science and the Mystery", which will be held 17th November 2010 on the Silesian University in Katowice. The conference is addressed to the whole academic environment, in particular to students and doctoral students. It is organised by the Academic Ministry in Katowice and the Institute of Physics of Silesian University. More information can be found on the address da.katowice.pl and by e-mail (konferencja@da.katowice.pl).

Detailed descriptions of the activities, which will be held in the Institute of Mathematics of Silesian University during the Silesian Scientists' Night, are available here.SILESIAN SCIENTISTS' NIGHT 2010 IN INTSITUTE OF MATHEMATICS OF SILESIAN UNIVERSITY IN KATOWICE

LECTURES:
(taking place in Aula Kopernika (room no. 213) in the Institute of Mathematics SU)

17.00-18.00 mgr Łukasz Dawidowski: How did our parents, grandparents count?
Today, with calculators being primary calculating devices, it's hard to imagine a world without computers. During this short presentation participants will learn about development of calculating techniques throughout the ages, from the simplest antic systems to the abacus and slide-rule.

18.00-18.30 dr Żywilla Fechner: How can one measure the risk?
We will be interested mainly in the risk concerning our finances. We know intuitively, that shares are more risky than debentures. We base our intuitions on certain experience from the past. However, some surprises may occur, for example debentures are not so sure if we invested in ones from Greece or Iceland. It is not possible to eliminate risk completely. One can, however, try to measure it. Such measures are applied in practice by various financial institutions. Appropriate assessment of risk is required in banking services. During the presentation we will take a look on various risk measures used by banks. We will try to answer the quesion, how are the risks concerning our savings measured and are these measures of any good.

18.30-19.00 mgr Grzegorz Bartosz: About a certain recursive problem
The talk will concern the Collatz hipothesis, an open mathematical problem, which on the first glance appears to be a mediocre task, which a clever secondary school student would be able to solve. The history of the problemm will be discussed and the correctness of it will be shown for certain parameters. Apparently correct proofs of the hipothesis will be shown, along with their hidden mistakes and some (correct) results giving partial answers to the question at hand.

19.15-20.15 prof. Maciej Sablik, Dean of the Faculty of Mathematics, Physics and Chemistry SU: Financial pyramid, i.e. how to defend your money
The presentation will open with a short prelection concerning financial mathematics, after which the participants will have an opportunity to learn about the financial market's mechanisms. Next, the participants will test their newly acquired knowledge in practice.

WORKSHOPS:

17.00-22.00 Piotr Idzik, Mateusz Jurczyński: Fractals (starting hourly, room no. 221)
Nowadays we observe a growing interest in fractals and their visualisations. During this workshop the participants will learn, what the fractals really are. The ways of creating both simple and the more complicated fractals will be presented, along with visualisations of those most beautiful. The listeners will be able to participate in the creation of fractals and in some competitions.

17.00-22.00 Jolanta Marzec, Marek Biedrzycki: Encryption (starting hourly, room no. 429)
During this workshop the participants will face the most popular ciphers and they will try to read an enciphered letter themselves. They will be introduced to the world of cryptography and learn the most typical ways of deciphering an encrypted text.

17.00-22.00 Aleksandra Urban with Rafał Besowski, Anna Jacek and Anita Sendor: Jigsaws & Puzzles (continuous workshop (you can enter anytime), room no. 208)
Free the ring, Do a cartwheel, Free the heart. These aren't quotes from The Lord of the Rings, exercises from PE classes or song titles, but the tasks from the Jigsaws & Puzzles workshop. Hands and brains will be bent by various manual tasks (wire and wooden ones, luck cubes), and when the fingers start to hurt, one can relax in front of a Sudoku, Cryptarythm, Algebraph and many more. The workshop is addressed mainly to the younger participants (primary, secondary and fresh high school students). However, all aged 4 to 125 are welcome to join :).

17.00-22.00 mgr Wojciech Bielas with Joanna Frej, Beata Łojan and Joanna Zwierzyńska: The Scottish Cafe(continuous workshop (you can enter anytime), room no. 211)
The Scottish Cafe is a legendary place of meetings of a group of Polish mathematicians in Lwow (in particular Stefan Banach, Stanisław Ulam or Stanisław Mazur). During their long meetings they solved mathematical problems, which they would write on table tops and in a special book (called later the Scottish Book). For solving some of the tasks various rewards were given, like geese. During this workshop we would like to restore the climate of that interwar cafe, in which young mathematicians would talk about mathematics and solve their problems on table tops. Here it will also be possible to buy delicious cakes, drinks and small souvenirs for the PIn money acquired at other workshops.

During the Silesian Scientists' Night, which will take part at 24th September 2010 current and former members of our Society will give popular science lectures and conduct thematical workshops.

The detailed schedule is provided below (any changes will be notified on our website).

We wanted to announce
the Silesian Scientists' Night, which will take place on 24th September 2010.

The event's purpose is to popularise science among broader public, so everyone are welcome, including (maybe especially) those, who do not have much contact with science in their everyday life.

Members of the Silesian Mathematical Society of the Silesian University will prepare talks and workshops from fractals, cryptography and puzzles. A detailed schedule of these activities will be available shortly.

Come and have fun!

Information about the Global Management Challenge - the Polish biggest management training, based on computer simulations - is available. Teams of three to five people can participate in the competition, which will play roles of administrators of international companies. Their aim is to administrate the company in such a way so as to obtain the highest stock value. More info here →

The registration of teams for the XI Global Management Challenge - the world's biggest business simulation - has begun!

Once again, teams of students and representatives of leading companies will compete on the virtual stock-exchange.

GMC is the biggest Polish management training in virtual reality, directed to students and company representatives. The project is based on computer simulation, which imitates the real world of business. The enterprise exists in Poland since 2000. National editions take place paralelly in 31 countries. Last year, the interest in it exceeded all expectations of the organisers. Over 500 company and student teams - i.e. approximately 2000 people - took part in the competition.

Teams of participants play the roles of international companies' boards of directors. Their task is to manage the firm through making decisions in fields of finances, marketing, production, sales, human resources management. The participants' aim is to achieve the highest stock value on the stock-exchange (the only criterion in the competition). GMC is an interactive simulation, in which the participants have to anticipate the other competitors' movements and react to changes on the market.

Students of 2nd-5th year from all universities and specializations can take part in the competition. They have to form a team (3-5 people) and register at www.gmcpoland.pl. Thanks to our sponsors, the competitors can participate free of charge. The winners of the national edition will go to the international final as representatives of Poland. The best teams will also get attractive prizes (e.g. studies in the Leon Kozminski Academy, taking part in a prestigious seminar "Authorities", bestsellers of business character).

The competition consists of a training program (October 2010), two online stages (November - December 2010, January - February 2011), national final (March 2011) and world final (April/May 2011).

The project is held under the patronage of the Warsaw Stock Exchange and the National Polish Bank. Telekomunikacja Polska SA and Bank Zachodni WBK already confirmed their presence as the General Sponsors of GMC 2010.

To take part in the training program, one should register before 15th October 2010. More information:www.gmcpoland.pl.

In the Informator of the Provincial Pedagogical Library in Katowice,
Bytom branch, a review of a book popularising mathematics "Tajemnicza liczba e i inne sekrety matematyki" (The mysterious number e and other secrets of mathematics) was published, written by Mateusz Jurczyński. Have a good read!

At the beginning of July The Great Society Cleaning will commence in the room no. 524. All broken mugs, umbrellas, plates, the "unused since times immemorial" old monitor and similar things will disappear, so the owners of those are asked to take them until the end of June, or, if it's impossible for any reason, to contact us at knm@knm.katowice.pl.

Join us at the members-reanimators of Student Mathematical Society SU (and not only them) meeting, during which a talk "My passion, i.e. some words about the Lusatian languages" will be held by dr Michał Machura.

The meeting will take place on 29th June of 2010 r., at 16.00 in room no. 228 of the Institute of Mathematics SU.

We announce that a new board of directors of the Students' Mathematical Society of Silesian University has been elected. It consists of: Mateusz Jurczyński (president) and Joanna Zwierzyńska, Szymon Draga and Marek Biedrzycki (assistants).

The Organisation Bureau decided that the 6th Students' Festival of Science 2010 will take place on 26th - 29th April (Monday - Thursday).

The members of Students' Mathematical Society will await all participants at their stand near the Bankowa street during the Knowledge Fair (on Wednesday and Thursday). At appropriate hours it will also be possible to take part in the prepared workshops.

The academic society from the Silesian province announces that on Wednesday, 14th April 2010, at 12.00 a mass for the victims of the Smolensk disaster will be said in the Christ the King Archsee in Katowice.
The mass will be said by the Katowice metropolitan abp Damian Zimoń.

More information available at the Silesian University's in Katowice website.

Because of the Smolensk tragedy, we announce that the Festival of Science, scheduled to 12-15th April 2010, will take place on a later date.

The academical society mourns together with the victims' relatives.

Easter is coming, time of joy and bliss,

We announce that on Tuesday, 12th January 2010 r., at 19.00 in the Academic Church in Christ the King Crypt in Cathedral at Jordan street in Katowice a mass for Professor Andrzej Lasota will be said.

We announce that on Friday, 15th January 2010, a Talk in memory of Professor Andrzej Lasota will be given by prof. dr hab. Andrzej Pelczar. The title of the talk is "Description of mathematics. Description in mathematics. Mathematics as a description." The meeting will begin at 15.30 in room no. 227 of the Institute of Mathematics SU.

We encourage everyone to participate in the talk!

Three years ago, on 28th December 2006,

Prof. zw. dr. hab. Andrzej Lasota,

one of the greatest Polish mathematicians,
a Honoris Causa doctor of the Silesian University,
an active member of Polish Academy of Science,
an active member of Polish Academy of Arts and Sciences,
a many-year Professor of the Silesian University,
died. Polish science suffered an irreparable loss.

We remember You, Professor!

In relation to third anniversary of prof. Lasota's death, the website of SMS will have a black&white layout in the days 28-31 December 2009 and in the upper left corner His picture will be visible. A memory about the Professor is available in a special issue of Macierzator.

It is Christmas here already,
Tables full of a food mix,
Merry Christmas are wished to you -
By us and the e^x!
And when New Year's Eve is yonder,
You will count from ten or nine,
Everything will be nice and simple,
Even the graph of a cosine.

Did you know that on Christmas Eve functions talk with a human voice?

In the Society's room a christmas tree appeared today. The Big Gluing of The Chains is scheduled for Thursday before the Society's talk - we need all the color paper we can muster. The christmas tree is two metres tall, so feel free to bring glass balls and other decoration. The idea and the tree come from Weronika, so - thanks, Weronika :)

We give our thanks to all who participated in the Christmas fund-raising on behalf of the Orphanage "Stanica". As every year, you have shown your worth - our baskets filled with great gifts everyday. Thank you!

We encourage everyone to participate in our Christmas fund-raising, organised annually by SMS SU. This time the fund-raising will take place between 30th November and 4th December 2009, and the collected gifts will be given to children from the Katowice Oprhanage "Stanica". They are teenage boys. Details ->

This year we collect:

* drawing accessories (e.g. pens, pencils, crayons, paint),
* paper accessories (e.g. notebooks, bristols, drawing-pads),
* cleaning utensils (e.g. soap, men deodorants, shaving accessories, feet deodorants),
* computer games.

There will be special, labelled containers at the Faculty of Mathematics, Physics and Chemistry, where one would be able to leave the gifts.

More information available at the Society's room (524) or by mail (knm@knm.katowice.pl).

We kindly encourage everyone interested to participate in the talk "Dedekind, Cantor and Kronecker", given by prof. dr hab. Jerzy Mioduszewski. The meeting will take place on 20th November 2009 at 12.15 in the 3rd symposial room (4th floor) of the Faculty of Social Sciences of the Silesian University in Katowice (Bankowa 11 street). The talk is meant as an introduction to the seminar "History of mathematics: people-ideas-philosophical aspects" organised by 7th Group of the Kopernik Centre of Interdisciplinary Research and the Institute of Philosophy of the Silesian University.

After years of struggle and tears, the Society's Paper [Macierzator], loved by many, hated by some, always up to date, always writing about the most pressing issues (all theses up to isomorphism) have acquired a TeX version! On this occassion the last issue is sponsored by Jeremias the Horse and the letter T, which can be found in the name of the tuned-up version.
We give our biggest thanks to the Author of this big change and we wish our Readers that the pleasure from the lecture tends to infinity even faster!

We remind you that the information about all cyclic meetings are available at suitable subpages:

- talk meetings of the Society - page "Meetings"
- talks for high school students - page "For high schools";
- Circle for high school students - also in the page "For high schools". Details ->

Information about every meeting for high school students appears on the main page minimum three days before the meeting, and - to improve the page's legibility - disappears 45 minutes after beginning the meeting. Only the announcement about the first meeting of a given academic year of each type stays on the main page forever.

We advise all interested to watch appropriate subpages - the lack of new announcement on the main page does not mean nothing interesting is happening:).

We also remind you that after every meeting scripts, problems, audiovisual recordings or pictures are available at suitable subpages. We also encourage you to leave comments.

We kindly invite everyone interested for the neares Society's talk meeting. On 19th November 2009 at 15.15 Tomasz Kania will give a talk "Martin's axiom". The talk will take place in the room no. 533.

After the talk an organisational meeting concerning the Pi Days will be held.

First time in the history of our outgoing science session we have to announce that we don't accept any new applications for the conference. The interest in the trip exceeded our greatest expectations, we are over our limit of places, so, unfortunately, the list of participants of the session "Mathematics in pictures" is officially closed.

We kindly invite all interested for the first in this academic year Society's talk meeting. The SMS president, Weronika Siwek, on Thursday, 29th October, at 15 o'clock in room no. 524 (Society's room) will give a talk "Lebesgue measure, I and II category sets, Borel sets". Participants of the outgoing session "Mathematics in pictures" are especially encouraged to be present at the talk - topics introduced by Weronika may be very useful during it.

We kindly inform all interested, that on the nearest Wednesday (21st October) we are planning to format the Society's computer. We suggest to copy all important files (if someone does not have the time or the possibility to visit 524 and has something important - contact me) - we will copy whatever we deem worthwhile, and the rest will disappear into the abbyss... and let's hope that it will improve the computer's functionality at least a little bit.

The Silesian Mathematical Society hereby announces the science trip to Szczyrk between 6th - 8th November 2009. The topic of the conference is "Mathematics in pictures".

More information available here ->

1. Conference, as is our tradition, will take place in the holiday resort of Silesian University in Szczyrk, on 56 Olimpijska street. You can get there by going by train to Bielsko, then by PKS to Szczyrk (direction: Salmopol or Biały Krzyż (the White Cross)), then getting out on the Szczyrk - Wodospad (Waterfall) bus stop (third after the Szczyrk centre) and going a few minutes by the road to the left of the street the PKS was going by, immediately before the bus stop itself - that is Olimpijska street. You can check the exact route on the map.
If you are not sure if you will find the place by yourself, you can contact us (knm@knm.katowice.pl). A few days before the trip, when we know exactly who will go, a group of people (with at least one of them knowing the way) will be chosen. If someone is going by car, please inform us about it, so that the empty seats in the car could be used.
2. You can sign up for the trip by informing any member of the Society - we can be easily found in the 524 room. You can also mail us at knm@knm.katowice.pl">knm@knm.katowice.pl.
3. Cost of the trip (without the journey) is 50 zł (with full board and accommodation). You can tell us your nutritional preferences (we cook ourselves), of course within reasonable limits.
4. We have the dishes, beds and bedding in Szczyrk. If, however, we will have more participants than beds (we never have, but better safe than sorry), those last to apply for the trip will have to provide their own sleeping bags and foam pads - those so unlucky will be informed earlier. You can take your own cup (which is kinda handy, if there are many people present). We also remind you to take some waterproof clothes and warm ones and shoes suitable for asome mountain hiking - if the weather is good, we may want to go for a longer excursion (for volunteers, of course).
5. The trip is theoretically scientific. Participating in the trip is not equivalent to giving a talk, but it's strongly recommended. The topic is „Mathematics in pictures". The talk does not have to be long or overly sophisticated and it can relate to various branches of science. Giving a talk is appreciated especially among our guests from places other than the Silesia University - of course, it is not a neccessary condition. However, in the case of exceptionally large amount of participants willing to go, those with a talk (or having given a talk at one of the previous sessions) will have priority.

Number of places is limited, so you should hurry ;) Please provide information whether you will give a talk or not, and in the first case - send the title. Applying for the trip as early as possible will be appreciated.

Questions and suggestions may be sent to knm@knm.katowice.pl">knm@knm.katowice.pl. See you in Szczyrk!

We hereby announce that on next Saturday a mathematical circle for high school students will have its official first meeting. It will take place on 10th October 2009 at 9.20 in room no. 2010 and will be held by Jola Marzec. The leading topic is "Congruences".

Feel free to join us!

We hereby announce that after the holiday break we resume the Friday meetings with high school students. The next meeting will take place on 9th October 2009 at 16.10 in room no. 213 (Kopernik's assembly hall), where Piotr Idzik will give a talk "On drawing graphs of functions".

News about every talk and materials from them will be uploaded consecutively at the "For high schools" subpage.

Feel free to join us!

Congratulations to all those qualified for the mathematical studies at the University of Silesia in the academic year 2009/2010!

At the same time we announce that on Wednesday, 14th July 2009, a integration meeting of fresh students will take place, organised by themselves ;) Gathering at 13 o'clock in front of the Institute of Mathematics. On behalf of the organisers we invite you to join!

We invite the participants of our talks who have not received their diplomas yet to pick them up. Those eager to do so are asked to contact us first at knm@knm.katowice.pl.

Soon in the SMS room The Great Spring Cleaning will take place. All interested are kindly informed that we are planning to throw out many things, so we suggest to take your stuff quickly, while it's still available.

The Silesian Mathematical Society hereby announces the science trip to Szczyrk between 30th April - 3rd May 2009. The topic of the conference is "Equations and inequalities".

However, in the case of exceptionally large amount of participants willing to go, those with a talk (or having given a talk at one of the previous sessions) will have priority.

Number of places is limited, so you should hurry ;) Please provide information whether you will give a talk or not, and in the first case - send the title. Applying for the trip as early as possible will be appreciated.

Questions and suggestions may be sent to knm@knm.katowice.pl">knm@knm.katowice.pl. See you in Szczyrk!

Festival of Science is currently taking place at the University of Silesia. Once can get to know how does studies look like on various faculties and branches or talk wih students. On Thursday, 23rd April, we invite all eager high school students to mathematics - we will wait for them in rooms no. 230 and 231.

More information here ->

We can talk about mathematical studies, professional perspectives after and during it, tutors, subjects, problems, fractals, books and mountains. In room no. 231 cyclic presentation of fractals will also take place and one will have the opportunity to learn some theory behind them.

How to get to the rooms? One has to enter the Institute of Mathematics building, and then follow the orange arrows ;) We will wait for you from 8.30 to 15 o'clock.

A presentation of the project One master, two degrees by doctor Michał Wojtylak from the VU University of Amsterdam will take place on Tuesday, 17th March 2009, at 10 o'clock in room no. 227.

Everyone is welcome.

A few days ago we have uploaded photos from the 5th International Students' Conference on Analysis in Szare. For your convenience, we have sorted them into various folders, firstly by date, secondly by events.
We encourage you to view and comment the photos, preferably in English.

During this year's Pi Days a cross-university run will be held for the first time. It's addressed to the high school students and exceptional gymnasion pupils. We accept applications until 8th March 2009 (included) at the bieg@swietopi.pl>bieg@swietopi.pl address.

More information ->

Eight three-people teams will participate in the competition, elected at random from the teams that will apply.

During the run teams will have to solve 8 problems, where elementary knowledge from physics, chemistry, information technology and mathematics will be needed. The problems will have the form of riddles and jigsaws popularising the four aforementioned branches of science. To solve them one will have to be able to use his knowledge and to think logically. Moreover, to get to each station, one will have to solve a short riddle, whose answer will be the address of next station.

The winner of the competition will be the team, which will solve the problems and arrive to the finish line in the shortest time.

We accept applications until 8th March 2009 inclusive, at the address bieg@swietopi.pl.

The organisers of the run are Students' Mathematical Society US, Koło Naukowe Pasjonatów Informatyki UŚ, Koło Naukowe Fizyków UŚ i Koło Naukowe Chemików UŚ.

Questions can be sent to bieg@swietopi.pl.

We invite everybody to participate in a mathematical contest e-ΠgraM. It is addressed to students of high and secondary schools and consists of two parts: Internet one and the final, which will be held during the Pi Days. More information here ->

The Internet stage will begin on 25th February 2009. At the website swietopi.pl/epigramat four problems from different branches of mathematics will appear. One would be able to send the solution up to 28th February inclusive. On 27th February 6 other problems will appear, solutions of which would have to be provided by 3rd March inclusive.

The results of the Internet stage will be announced on 6th March 2009. 10 participants with the highest amount of points will be qualified for the final, which will be held on 13th March 2009 in the Institute of Mathematics of University of Silesia - the participants will listen to a short talk and then will get three problems related to the talk to solve. The prizes will be awarded almost immediately after the final. More information and a detailed statute is availble at the Pi Days webpage. In case of questions, one may also ask the contest's coordinator, dr Tomasz Bielaczyc.

Today at 21.00 we've uploaded the results of the "Mathematical riddles" competition. We hereby congratulate the winners!
Prizes will be awarded during this year's Pi Days.

We stopped accepting applications for the contest "Mathematical riddles" yesterday. Thanks to all participants and congratulations for quite good results ;) They will be announced shortly at SMS website.

We announve that on 16th January 2009 at 16 o'clock in room no. 227 a talk in memory of Professor Andrzej Lasota will be given by prof. Michael C. Mackey, worldwide known scientist from the McGill University in Montreal. The talk is entitled "Exploring the World with Mathematics". More information available at the appropriate subpage of the Institute of Mathematics' website.


Not everyone knows that prof. Lasota and prof. Mackey published a joint monograph "Chaos, Fractals and Noise", published by Cambridge University Press. One can read about their collaboration and friendship in an interview with prof. Lasota, published in an archival issue of the "University Paper".

We encourage everyone to participate in the talk!

Two years ago, on 28th December 2006,

Prof. zw. dr. hab. Andrzej Lasota,

one of the greatest Polish mathematicians,
a Honoris Causa doctor of the Silesian University,
an active member of Polish Academy of Science,
an active member of Polish Academy of Arts and Sciences,
a many-year Professor of the Silesian University,
died. Polish science suffered an irreparable loss.

We remember You, Professor!

In relation to fourth anniversary of prof.Andrzej Lasota's death, the website of SMS will have a black&white layout in the days 28-31 December 2010 and in the upper left corner His picture will be visible. A memory about the Professor is available in a special issue of Macierzator.

As a Christmas present we uploaded the rebuses in a much better quality: you can receive the gift here. We remind everyone that prizes (including a special one...) await ;)

It is Christmas here already,
Tables full of a food mix,
Merry Christmas are wished to you -
By us and the ex!
And when New Year's Eve is yonder,
You will count from ten or nine,
Everything will be nice and simple,
Even the graph of a cosine.

Did you know that on Christmas Eve functions talk with a human voice?

We hereby announce that the Society's Christmas meeting will be held on Friday, 19th December, in evening hours (we begin after the talk for high school students, so at about 17.30). All current and former members of SMS are sincerely invited to room no. 524.

Due to a great interest in the „Mathematical puzzles” competition, we hereby announce that a special award of a bar of chocolate will be awarded to the first student, doctoral student or research worker of the University of Silesia, who will solve all the rebuses as the first. Applications will be received in the Students' Mathematical Society room (no. 524).

We hereby announce that the meeting with dr Jolanta Kazak, during which she will give a talk Mathematics for life will be held on 18th December 2009 at 12 o'clock in room no. 227 of Institute of Mathematics of the University of Silesia in Katowice.


Dr Jolanta Kazak is a lecturer in the Institute of Mathematics of University of Silesia and a volunteer of the Charity Centre "LOYAL" („CChW SOLIDARNI"), which is an organisation separated from the Prowincja Polska Stowarzyszenia Misji Afrykańskich (SMA - solidarni.sma.pl). During the last three months she participated in a project Mathematics for life - education of pupils and teachers in the Bugisi Mission in Tanzania. The purpose of her work was to educate current and future teachers of mathematics, along with children. Now she wants to share her experiences and recount her experiences and tell about the project itself, which was realised in Eastern Africa.

Dr Jolanta Kazak will present the assumptions of the project along with its course and realisation in a multimedia presentation. There will be time for discussion.

In the name of the Students' Mathematical Society I would like to announce the "Mathematical riddles" contest and encourage everyone to participate. More information here ->

On Thursday, 11th December 2008, at 21 o'clock at Society's website in the CONTEST subpage a file will appear containing the rebuses made by SMS members. All will have some connection with mathematics - the solutions will be mathematical notions, and to solve them one would need, except for creativity, elementary mathematical knowledge. The difficulty will be varied - from very simple, solvable even for junior high school pupils, to those requiring knowledge beyond high school.

Three people, who by the end of January 2009 send the most correct solutions, will get diplomas and small prizes. They will be awarded during the Pi Days. In case of the same number of solutions, those who applied first will get the prize. The mail address to which one should send the solutions will appear along with the problems on 11th December 2008. [Edit: the address is rebusy2008@knm.katowice.pl]

We encourage everyone to take part in the competition!

Between 1st and 5th December 2008 on the Faculty of Mathematics, Physics and Chemistry of US a
Christmas fund-raising
will be organised. The gifts will be passed to the Guardian Angels' House, taking care of children from the poorest families of Załęże. More information ->

The Guardian Angels' House is created by a group of teachers, psychologists and tutors, taking care of rejected and neglected children, who often have no perspectives other than drugs and alcohol. They need practically everything.

More information about the organisation is to be found at www.anioly24.pl.

This year GAH published a list of most needed things. It includes learning materials, household materials (the children have to learn how to function in a society - how to cook, clean and... wash themselves), educational toys and things to develop sport passions of the young. Full list is available at www.anioly24.pl/prosimy-o-pomoc.php. We gather everything that is on the list, for example:

socks, underwear and footwear (in large quantities - they don't have any and wear dirty, worn out things)

educational toys and games (like Rummikub, Farmer)

sport accessories, like rollerskates (for the children to develop their passions)

fabric, threads, needles, scissors and other tailor utensils (for the children to learn how to sew, but also so they can make themselves dancing uniforms)

towels and rags for the kitchen (there's always too few of them)

all cleaning utensils

fairy tales on DVD

tools (useful in two different ways: children learn how to use them by repairing and renovating their place)

plastic boxes of various sizes

and many more things. Maybe you have an old bike that nobody uses? Or a tourist backpack you don't need? Things can be used, as long as they are not in a bad shape.

Gifts can be brought to the Students' Mathematical Society's room (no. 524 in the Institute of Mathematics). Moreover, in all buildings of the Faculty of Mathematics, Physics and Chemistry special boxes will be exposed.

We strongly encourage everyone to participate in our action!

On the behalf of Students' Mathematical Society of the Mikołaj Kopernik University in Toruń we would like to invite all interested students and doctoral students to participate in the Toruń Summer School of Mathematics. More information here ->

The workshops entitled „Toruń Summer School of Mathematics" will take place between 31.08.2009-4.09.2009. The topics which will be covered include:
- algebra and algebraic theories;
- mathematical analysis and topology;
- probability theory and statistics;
- basis of mathematics (logic, set theory).

There will be talks and workshops on every of these subjects, led by invited scientists, and parallel sessions, during which the participants will get to give their own talks.

The fee is 120 zł, which is little for five days of workshops, considering the fact that full board and accomodation is covered in it.

People interested in taking part in the trip can tell it until the end of November to the members of the Society (it's easiest to find us in room no. 524) or at knm@knm.katowice.pl. It is not equivalent to any declaration - we only want to estimate the number of those interested (it's important and urgent!).

Feel free to join :)

On Monday (9 X) at 12.00 in room no. 524 we will talk about the collaboration of SMS with the matematyka.org portal. All those interested - feeling they have something to say about the matter, or would simply like to know what it's all about - are invited. It shouldn't take long.

Pictures from the last camp can be downloaded in their full resolution (8MP) after logging in.

To everyone who have their own login and password - visit TATTLE, a special kind of forum for SMS members only :) (it's in the menu after you log in).

How about organising an internet competition for high school students? Problems would be proposed by the Society's members (only author's problems!). A competition could be held once per three months, or in a formula similar to the MO? It's just a scetch of an idea, give your thoughts.

As all interested probably know by now, the newest pictures from the "Theorems with Proofs" camp are available in the CAMPS/Theorems with proofs subpage.

Some new facilities were introduced to the user's panel, feel free to check them out.

The Site is online for over a month now. On this occassion, some statistics:

You will find information about the next SMS Summer Scientific Camp here.

We are happy to inform about some small enhancement in out room. Namely, since Thursday, May 18th we have a new sofa. Since now we not only can sit, but also lie.

The next meeting will be held on 19 May at 16.15 in room no. 213 (the usual). Agnieszka Klama will be our talker. The topic is "CONVEXITY". Feel free to come.

Those unsatisfied with their pictures on the "Membership" page are asked to send another photo to my address. Preferably in .jpg. For those who have a brown man instead of a photo, I'll find some in archival sessions or camps. They usually have bad quality, so you can as well send me another one now.

The mistake, due to which the website crashed after using inverted commas in a comment, has been corrected. Moreover, after a short discussion with the Society's management, we made emoticons available again. Although only a few are visible while commenting a photo, you can use almost all emoticons from popular internet communicators.

A problem given to us by Piotr Jan Szewczak:
We divide the set {1,2,...,3n} into three disjoint, non-empty subsets, which union is the whole set. Show that there exist numbers x, y, z, each from a different subset, such that x+y=z.
Looks interesting. Piotr told us he does not know the solution. We don't know, however, where the problem originated from.

Pictures from the last session of our Society are available. Feel free to add comments.

Every active member is kindly requested to update the contact informations and check the new email address.
