# Joint Math Meetings Wrap-Up

Over at Roots of Unity, I wrote a wrap-up of some of my and other people’s coverage of the Joint Math Meetings back in January.

From my coverage of Fields medalist Cedric Villani’s Gibbs lecture: “You should call it entropy, for t [...]

# Wrong in Public: the 4-Color Theorem ...

One of my readers pointed out an error in my recent post about the 4-color theorem. I wrote an update that reframes the theorem in terms of graph theory and talks about some corollaries of the theorem.
A diagram I created that illustrates part of an argument about the 4-color theorem.
My reasoning was that we could take a region of a map that [...]

# Having Fun with the 4-Color Theorem

Back in February, I visited a mathematician friend, and we colored some maps. What happens when mathematics and cartography collide? Some 4-color theorem fun.
The region of Europe directly surrounding Austria (red) is a real-world example of why it’s the 4-color theorem and not the 3-color theorem. Italy can’t be colored red, blue [...]

# Two Evelyns and a Katie: a Snapshot o...

Yours truly and Evelyn Ho, a high schooler who is doing some interesting research on Parkinson’s disease.
Evelyn Ho is a senior at Plano Senior High School, just 20 minutes from my parents’ house. The summer before her sophomore year of high school, her grandfather died of Parkinson’s disease, and her grandmother was diagnosed with the [...]

# Interview on Math Tango

“Shecky Riemann” of Math Frolic and Math Tango asked me a few questions about my approach to writing about math.
“I try to see myself as an entertainer at least as much as an educator. For the most part, I want my pieces to make people happy. If they learn something as well, that’s a nice bonus.”
You can read the [...]
