cv talks songs Candidate A is your favorite, but you are told that you must vote for a worse candidate B because your vote for candidate A would help the worst candidate C. The current voting system punishes you for voting honestly. Do you like two out of five candidates equally? The current ballot does not let you express your opinion. The result? Politicians with unpopular agendas are elected. Do you want democracy? Demand a simple, purely mathematical solution: approval voting, or better the more general score voting aka range voting, or even better its variation called STAR voting. Any one of these is better than rankedchoice voting aka IRV. Much better. Do not advocate for rankedchoice, it's a distraction. Bees have a better democracy. We need to keep up. Score voting is more important than the electoral college. It is more important than gerrymandering. The country is not polarized; it just uses a corrupt voting system. Spread the word. Discuss and demand. Will the politicians allow score voting? This is not a mathematical question. 
Our new Illini Hall building  make it SOLAR. I am a Professor at UIUC Math Dept. My mathematical interests include subjects related to geometric group theory, in particular,
IG^{3}OR'S Teaching in Fall 2022: The video orangeandblue SPACE FISH and SPACE CLOCK. Make it fullscreen and watch from the beginning to the end. When you finish your meditative journey, the highest mathematical truth might descend upon you. (Use Safari or Chrome. Firefox does not seem to work on this.) Do you recognize the function in this video? (Hint: It was introduced in 1859. And no, it was not in Darwin's "The origin of species".) 
G^{3} conference

The mathematically correct name is "gee cube".
As y'all know, G^{3} stands for the annual
Geometric Group Theory on the Gulf Coast Conference, commonly
abbreviated in various ways, like
Geometric Groups on the Gulf.
G^{3} conference is currently not running.

"Mathematics is a piece of cake:
if you like it, you will get it."
"My theory is that no matter how hard people try to describe the real world, any theory would give only a rough approximation to the reality. Except for my theory." "...a point has the nonzero zero homology and the zero nonzero homology..." I.V.Mineyev, hopenotyetcomplete works. 

A Mathematician's Lament
by Paul Lockhart. What you hated in school was not mathematics. 
A quote from teaching evaluations: Instructor's weakness: high expectations. 
Freedom.  Another quote from teaching evaluations: Do not teach proofs. They are useless. Teach what needs to be done on the homework and tests. 
A very important statement.  Funny math pictures from V.Troitsky.

Please don't get discouraged if I don't reply. I have email anxiety, and a mild form of keyboard incompatibility. I read email, but not regularly, and it takes time. Email also happens to be a distraction from deep thinking. I'm working on my email skills, it's a process. Meet me in person, I'm much nicer that way. :) If you want to write me something important, a regular mail letter might be a better option.
