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. The result? Politicians with unpopular agendas are elected. Do you want democracy? Do you want your true opinion to be counted? Demand a simple, purely mathematical solution: approval voting, or the more general score voting = range voting. Either one is better than rankedchoice voting. Bees have a better democracy. We need to keep up. Will the politicians allow these voting systems? This is not a mathematical question. 
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 the Spring 2018: Math 417 and Math 432. Teaching in the Fall 2018:

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.
We have not received funding from NSF, so there is no G^{3} conference in 2018.

Miscellaneous 
"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 discoraged 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.
