Stephen Sekula (steve)'s status on Tuesday, 06-Apr-2021 20:50:53 EDT Stephen Sekula Had an awesome seni-normal moment today. Masked and socially distanced, one of our #PHYS1303 students and I used a force meter to measure the coefficient of static friction between a horseshoe and silicone. I said semi-normal. I was clear. https://twitter.com/drsekula/status/1379595353708724227/photo/1 https://chirp.cooleysekula.net/attachment/71618
