The physics of Jake Brown's ollie 720

I'm a couple weeks late on this, but recently Jake Brown landed the first ever ollie 720.  To put that in layman's terms, he did two full rotations without holding the board on his feet with his hands.  Check it out:



So this seems crazy.  How did he do that?  How did he keep the board on his feet?  Magnets?  It turns out, it's actually very simple physics:

The Conservation of Energy


That's it!  Jake Brown doesn't really have to do anything because the conservation of energy won't be violated (it's a law!).  So yeah, thanks physics!  Skateboarding is so easy.



Popularizing Science One Operator at a Time

One thing I'm very interested in is the popularization of science and other STEM related fields.  I feel that it's very important to maintain a society that is both scientifically literate and scientifically enthusiastic.

This has motivated me to purpose a new notation for the total angular momentum operator in quantum mechanics that will be more appealing to the general public and more specifically the "cool youth" of today:




It's like flipping through a celebrity gossip magazine while you compute matrix elements!
