My all-time favorite variational calculus example! Well illustrated. Dillon you rule.https://twitter.com/InertialObservr/status/1153018532369555456 …

It works thanks to gravity, otherwise it won't!

Actually the brachistochrone has analogies in nearly every field theory that has a certain kind of potential. It’s pretty cool.

@InertialObservr can, in one tweet, show how this works for quarks in a color glass.

indeed in a classical field theory the brachistochrone has a direct analog, however in a quantum field theory there will be quantum corrections to the classical path

Also I’m a dick because QCD doesn’t have the kid of potential we need for this. But it’s fun to talk about.
