I paused #DailyMechanician in April last year, since there were other tasks I wanted to prioritize at the time. Life only got busier. Though still doubtful about tweeting daily again, I'm ready to slowly resume the mini project. Stay tuned!

@ProfRausch “Dear, Prof. Rausch: I enjoy the memes you post on X/Twitter and look forward to lifting the figurative wheelbarrow under your supervision.” Would that work? 😅 (Seriously though, awesome thread! Will share with friends who plans to spam email potential advisers)

It was saddening to read this account of a hate crime experienced by Dr. Suk, a friend and colleague of my wife’s. The bystander apathy described here is heartbreaking. #StopAAPIHate
1/x Never thought I’d share this kind of story. Was at @nycgov for a family gathering and on the NYC subway, I was *physically* and *verbally* attacked by a woman who punched my side with her fist and yelled at me, saying ching chong, dumbass, f*ck,

#DailyMechanician Moritz Weber was a naval mechanics professor at today's @TUBerlin, in early 20th century. A proponent of similitude & dimensional analysis, he is accredited for coining the Reynolds and Froude numbers. Fittingly, a dimensionless number is also named after him.
