Great piece by Emily Riehl on what mathematics is today: www.science.org/doi/10.1126/...
Mathematics is hard for mathematicians to understand too
At a recent conference on mathematics in the age of automated proofs, mathematician and Fields Medalist Akshay Venkatesh presented “How do we talk to our students about AI?'' He quoted an email he'd r...

The crisis isn’t refugees. It’s not that one person committed one tragic crime and killed one other person. The crisis isn’t that America’s 250-year old history of hosting immigrants turned out to be a mistake.
The crisis is that STEPHEN MILLER, a hateful little maggot, controls the government.

Stunning number
Over 40% of corn grown in Indiana is used to make ethanol that cars burn. One acre of corn yields about 16,500 vehicle-miles per year of ethanol, which sounds high until you realize that one acre of solar yields about 2,700,000 vehicle-miles per year: 16,000% more driving for a given plot of land.

Everybody has civil rights or nobody does
Iowa is on the brink of doing what no other state has: revoking statutory civil rights protections for trans people.
In 2007, the legislature expanded Iowa’s civil rights law to include sexual orientation & gender identity.
Today, the legislature passed a bill to take gender identity out.
