Was Richard Feynman really awarded a patent for a nuclear Airplane and Rocket?

I've been re-reading "Surely you're Joking Mr. Feynman", and at one point he talks about how at Los Alamos they were asked to write down any idea, no matter how obvious involving nuclear technology, ...

What actually led Feynman to the path integral formulation of quantum mechanics?

It is commonly known that Feynman's path integral was inspired by Dirac's observation that the kernel is proportional to $\exp{iS/\hbar}$. It was Feynman, however, who had the idea of expressing the ...

Is there any historical mention of Richard Feynman being aware of multiverse theories of cosmology?

The reason I ask is because he talks about the fine structure constant in one of his undergraduate lectures. The reference to its mystery is analogous to all the special constants of nature such as ...

Did Richard Feynman ever meet Stephen Hawking or comment on Hawking radiation?

I was just curious what Richard Feynman thought of Stephen Hawking's Hawking Radiation. Feynman was one of the developers of quantum field theory and Hawking's work would have been cutting edge on the ...

Why is differentiation under the integral sign named Feynman's trick?

It's a simple enough result I would have been unsurprised if it weren't named for anyone at all. I certainly find it odd it's named for a relatively modern physicist rather than an early-calculus ...

Was Richard Feynman a double major?

I know this might be a silly question, but I think it's worth asking. For his undergraduate degree at MIT, did he do a double major with math, or did he really just get that good at mathematics by ...
