Let's talk about Texas AD Chris Del Conte's run of hires. 2019: Mike White hired as the softball coach. Since: 3 CWS appearances, two runner-ups and a CWS title last year. Currently No. 2 in the country. 2020: Vic Schaefer hired as the WBB coach. Since: 5 conf championships (reg or tourney). 4/5 years in the Elite Eight. A Final Four appearance last year. Currently, one of the favorites to win it all in 2026. 2021: Steve Sarkisian hired as the football coach. Since: Two CFP semi-final appearances, B12 championship, SEC championship berth in first year in the conference, 48 wins in five seasons. Projected Top 3 team in 2026 2024: Jim Schlossnagle hired as the baseball coach. Since: SEC regular season title in 2025, 64-17 overall record, No. 2 team in the nation currently. 2025: Sean Miller hired as the MBB coach. Since: One of four SEC teams in the Sweet Sixteen, just the second berth for the program in 18 years. He's hired top-three coaches in the SEC in four of the six major sports at Texas, and Miller is already solidifying himself in the 6-8 range among SEC MBB coaches. An absolute masterclass

Here is a lovely geometric proof that sqrt(2) is irrational. The proof begins by looking at an isosceles right triangle whose legs have length 1. By the Pythagorean theorem, this triangle's hypotenuse will have length sqrt(2).

Today I learned a new and beautifully-simple proof that sqrt(2) is irrational and I feel the same giddy excitement as when I was a student. I can’t believe this is my job.

If you say "I am a math teacher" three times in front of a mirror, someone will appear and tell you how much they hated math in school.
