Weird hair and mathematicians

Warning: This short post touches on some heavier topics like suicide and relationship violence.  If you are having a mental health emergency, please reach out to a mental health professional, call 911, or a suicide / crisis hotline (in the US, the canonical number is 9-8-8) .  This post is a bare bones version of what I wish I could write here, but I'd rather get something out and maybe revisit topics in more detail later. Math is weird and has weird people in it.  I remember a close friend in college told me he was a math major because he liked the people - I agree (usually).  Mathematical culture seems to really emphasize being accepting of the weirdos, purporting that a love of mathematics is what matters.  Barefoot at a conference - not even an eyeroll.  (I had my barefoot phase in grad school too.)  Blue hair, you do you!  I like having the space to be weird, but of course, how welcome you are treated in the community can depend on race, gender, etc and this affects who really

Gerrymandering and mathematics

Sometimes I think about math which is not pure geometry/topology, so I want to discuss some of those areas in this blog as well.  This post was inspired by a recent talk of Moon Duchin in MD4SG and some discussions I had with Jim Allen and Manon Revel.  This is an oversimplification to get the ideas across - there are a lot of important ideas not present in this post.  If you want to learn more, check out Moon's group's  website , which has lots of nice visuals and interactive explanations.  Let me start with the background before getting into the math.  A major source of political conflict comes from gerrymandering .  If you're not familiar with this term, it's roughly the idea of restructuring voting districts to create some kind of political advantage.  I'll explain this a little further through the lens of the US system.  For simplicity, let's assume there are two political parties A and B in a state, which will be divided into voting districts.  For simp
