Physics of Staying Dry In The Rain

"Physicists tackle a crucial issue: How to stay dry in the rain"

The short version:

Basically, the best strategy for staying dry (or at least somewhat dry) is to run as fast as possible. Unless you’re really thin, in which case there may be a more optimal speed. And if you’ve got a tailwind behind you, then you should run exactly as fast as the wind at your back.
