Very excited that this video was one of five winners of the "helpful for teachers" supplementary prizes of #SoME4. I love it when teachers tell me that they used one of my videos in their classroom! 3blue1brown.substack.com/p/some4-prizes

Teddy was a friend in my graduate program. US policies and infrastructure consistently prioritize cars over cyclists and pedestrians. It's enraging. And very sad. tinyurl.com/3um2c44v

Teddy Einstein, a West Philly mathematician, was about to hit his stride. Then he was killed while riding his bike.

Teddy Einstein finished major research and would start a new job before he was killed earlier this month by a driver in Upper Darby. His family and friends remember the "brilliant" mathematician.

This is a great and concise introduction to popular paradoxes by @kelseyahe.bsky.social. I didn’t know about several of these. youtu.be/1vJsWKg2o1w?...
