Did Richard Feynman ever meet Stephen Hawking or comment on Hawking radiation?
I take that your primary goal is to know what Feynman thought of Hawking's work. While it is possible that they have met I would consider it unlikely given that Feynman mentioned several times how his ...

Is the "questions that can’t be answered over answers that can’t be questioned" quote by Feynman authentic?
This is all I have found for now:
“You see, one thing is, I can live with doubt, and uncertainty, and not knowing. I think it’s much more interesting to live, not knowing, than to have answers which ...

Did Feynman develop QED based on Stueckelberg's manuscript?
There seems to be enough evidence to believe that people were joking around about Stueckelberg's notes in 1965, when the Nobel prize was awarded to Feynman, Schwinger and Tomonaga, but I do not see ...

What actually led Feynman to the path integral formulation of quantum mechanics?
It was Dirac's paper The Lagrangian in Quantum Mechanics. He gave more than just a remark about $\exp{iS/\hbar}$, he described the general structure of the path integral expression for the transition ...

Wasn't Feynman's parton model the same as the quark model?
Wasn't his parton model simply the same as the quark model? Didn't he [Feynman] "just" put some flesh on the skeletal concept of quarks present inside hadrons?
Not at all! Before the ...

Is the "questions that can’t be answered over answers that can’t be questioned" quote by Feynman authentic?
I have my doubts, although Feynman, like many others, expressed similar sentiments. Dennett in the first chapter of Breaking the Spell (2006) writes:"Philosophy is questions that may never be answered....

Did Feynman win the Putnam by a "large margin"?
This is Feynman's memory of an unnamed person who told him that. To quote him in an interview:
Anyway, I was among the first five. I have since found out from somebody from Canada, where it was ...

What steps did Richard Feynman take to devise his Integral Trick?
According to the history given here, he didn't.
I had learned to do integrals by various methods shown in a book that my high school physics teacher Mr. Bader had given me. [It] showed how to ...

Did Richard Feynman ever meet Stephen Hawking or comment on Hawking radiation?
Dunno if they ever met in person. There's an interesting video (one of several sites available) which states that Feynman came up with the "Hawking Radiation" theory well before Hawking did, but didn'...

Why is differentiation under the integral sign named Feynman's trick?
The name comes from Feynman's evaluation of the integral
$$\int_0^\infty\frac{\sin x}{x}dx.$$
This is a classical example on applications of residues (I think it is originally due to Hardy. In the US ...

Did Feynman develop QED based on Stueckelberg's manuscript?
As implied by these quotes, could it really be that Stückelbergs manuscript in fact disappeared, because Feynman got hold of it, never returned it and used it to develop QED? And could it be that this ...

Onsager on phase transitions
First, the source linked by @Kvothe in a comment provides a wording that is (significantly) different from that in the OP.
Second, I can only guess what Onsager meant, but possibly that was about ...

I suspect you're referring to the Feynman anecdote about a submerged S-shaped sprinkler, which is mentioned in Part 2 of the book "Surely You're Joking, Mr. Feynman" (pages 63-65). The question he ...
