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!

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.

Teddy was a friend in my graduate program.
