Getting choked up...

For all the stuff that annoys me about the future, this makes it seem worthwhile.

"War is ugly and the American people need to know this."

"This theory puts forward the notion that depressed individuals actually have more realistic perceptions of their own image, importance, and abilities than the average person."

"Say howdy to George Carter, and thank him for taking the pistol from you when you were shooting at me."

Craaaaapped.

In a nutshell, Feynman’s astonishing proposition is that nature actually does try all paths. But nearly all of them cancel out with their neighboring paths, through a quantum analog of destructive interference — except for those very close to the classical path where the action is minimized (or more precisely, made stationary). There the quantum interference becomes constructive, rendering those paths exceedingly more likely to be observed. This, in Feynman’s account, is why nature obeys minimum principles. The key is that we live in the macroscopic world of everyday experience, where the actions are enormous compared to Planck’s constant. In that classical limit, quantum destructive interference becomes extremely strong and obliterates nearly everything that could otherwise happen.
