A Math Carnival at Illinois

You love mathematics? Fantastic! You don't like mathematics? Well, then give us a chance to change that! The Department of Mathematics at the University of Illinois at Urbana-Champaign would like to invite you and your family to our winter math carnival! The Gathering for Gardner 2017 will be held on Saturday, January 28, 2017 from 2 - 5 pm in Altgeld Hall. This fun filled day will be packed with hands on activities, demonstrations, games and puzzles, refreshments, and mathematical prizes for participants! All activities are free and open to the public and there is no math training required to enjoy! Our puzzles are particularly designed for kindergarten, elementary school, and middle school students. Please come visit us and bring the whole family!

PME is seeking application for membership

The local chapter of Pi Mu Epsilon (PME) is seeking application for membership. PME is the National Mathematics Honorary Society that serves to promote scholarly activity in mathematics among the students in academic institutions. To be elected as a member to the Illinois Alpha Chapter of Pi Mu Epsilon, an undergraduate student at the University of Illinois at Urbana-Champaign has to meet all of the following requirements:

(i) Completion of the calculus sequence through MATH 241 or the equivalent
(ii) Completion of at least two post-calculus courses that count toward a major in the mathematical sciences (e.g. any two of MATH 210, 347, 408 and 461)
(iii) a 3.5 or higher math GPA
(iv) a 3.2 or higher U of I GPA.

We are accepting applications from now until Friday, March 4, 2016. The membership form may be acquired from the Undergraduate Math Office in 313 Altgeld Hall or downloaded here. If you have any questions, please contact Professor Philipp Hieronymi (phierony@illinois.edu) or Math Advising (mathadvising@illinois.edu).

Enrollment - Math 415 - Fall 2015

If you are a student trying to enroll in one of my Math 415 sections, please note that enrollment is not handled by me, but by the undergraduate math advisers. You can contact them by stopping by 313 Altgeld Hall (business days between 8:30-noon or 1-4:30 pm) or send an e-mail to mathadvising@illinois.edu.

Impressions from the Gathering for Gardner 2014

At the occasion of Gardner's 100th birthday the Illinois Geometry Lab and Department of Mathematics at the University of Illinois at Urbana-Champaign hosted a celebration of recreational mathematics and fun math puzzles on Saturday October 11th of this year. This event, a Gathering for Gardner 2014, was to honor the achievements of popular mathematics writer Martin Gardner who, for over 50 years, entertained general audiences with a rich variety of mathematical puzzles. Local mathematicians and computer scientists provided demonstrations of magic tricks, visual paradoxes and much more! At our math fair children of all ages (and adults as well!) were able to attempt and solve a large variety of Gardner's puzzles. For pictures of the event, click here.

Gathering for Gardner 2014 - Oct 11, 1-4pm, Altgeld Hall

Come join Champaign-Urbana's celebration of the spirit of recreational mathematics and fun math puzzles, and the life of math and science writer Martin Gardner! At the occasion of Gardner's 100th birthday the University of Illinois will host a dozen local mathematicians and computer scientists who will present math puzzles, logic puzzles, hexaflexagons, magic tricks, visual paradoxes and much more! It is free and open to members of the public of all ages - no math training required to enjoy the puzzles and the mathematics! For more information, click here.

Workshop "Applications of O-Minimality to Analysis and Number Theory"

Passau, September 09-12, 2013 - The goal of the workshop is to bring together people from the areas of analysis and number theory which meet in o-minimality. Intended is a tutorial on the number theoretic problems recently attacked with tools from o-minimality. The heart of the workshop will be significant talks on the newest applications of o-minimality to analysis, analytic geometry and number theory. Read more...

REGS Project: Logic and Mathematics

Urbana, June, 2013 - The aim of the project is to study interactions of Logic with other branches of Mathematics. We will study fractal geometry and Cantor sets with the help of tools from Mathematical Logic. We may also consider connections with Diophantine number theory. The precise content will depend on background and interests of the student. Read more...

XIV Graduate Student Conference in Logic (GSCL)

Urbana, April 20-21, 2013 - The GSCL is an annual conference organized and run by graduate students in mathematical and philosophical logic. The two-day conference allows any graduate student from around the United States to give a talk on a topic in mathematical or philosophical logic to a large audience of young logicians. This year's conference is to take place at the University of Illinois at Urbana-Champaign during the weekend of April 20-21. Read more...

Back2Fields Colloquium - Philipp Hieronymi: Tame Geometry: A tale of two spirals

Toronto, October 11, 2012 - The Back2Fields Colloquium Series celebrates the accomplishments of former postdoctoral fellows of Fields Institute thematic programs. Over the past two decades, these programs attracted the rising stars of their fields and often launched very distinguished research careers. As part of the 20th anniversary celebrations, this series of colloquium talks will allow a general mathematical public to become familiar with some of their work. See video...

Annual Gathering for Gardner event celebrates recreational mathematics

Urbana, October 30, 2012 - If Captain Jack Sparrow has 100 gold doubloons, how can he distribute them amongst his ship's crew so that he keeps the largest share and still keep the crew happy enough to avoid walking the plank himself? This is just one of the puzzles posed to attendees of this year's Gathering for Gardner celebration. Read more...
