Or why a tennis racket flips like it does. The math is over my head but the end is worth it!

wow thanks for posting. best science video I’ve seen in ages.

It’s such an interesting twist on classical physics. The explanation makes total sense but I’m actually stunned that the system will/can find it’s lowest energy (highest moment) state and “do a 180", while almost seeming “intelligent”, in order to get to that configuration .  It’s truly wild.

Wingnuts are interesting, but I am just pleased that the planet isn’t going to do a flip on us.

Veritasium is a pretty good channel for science videos.

Does make you wonder if the earth DID flip at some point in its search for the optimal moment-configuration. Given the analysis (and the losses from tides, air movement, etc) I’d be surprised if it hadn’t flip...

Yes a good question. Especially as I recall that the arc tic was once tropical;
