The Fantastic Mr Feynman

In celebration of Feynman’s birthday.

Apologies for late post, shocking hangover kept me in bed all day.

Richard P. Feynman would have turned 95 today. We’ll miss him always.

Birthday

If you’re near London this weekend, Feynman birthday extravaganza:

“Playing” with Feynman diagrams via Shores of the Dirac Sea (Woof Woof)
More “funny” diagrams on this paper: More On Superstring Perturbation Theory.

So my antagonist said, “Is it impossible that there are flying saucers? Can you prove that it’s impossible?” “No”, I said, “I can’t prove it’s impossible. It’s just very unlikely”. At that he said, “You are very unscientific. If you can’t prove it impossible then how can you say that it’s unlikely?” But that is the way that is scientific. It is scientific only to say what is more likely and what less likely, and not to be proving all the time the possible and impossible.

sircle:

Yes.

If your favorite scientists throughout history were super-hip web start-ups, these would be their logos.

I would buy stock in that Feynman guy any day. He’s my dude. Check out the rest of the superb collection from Alan Betancourt.

[Subatomic particles] do not behave like waves, they do not behave like particles, they do not behave like clouds, or billiard balls, or weights on springs, or like anything you have ever seen.

“…will you understand what I’m going to tell you? …No, you’re not going to be able to understand it. …I don’t understand it. Nobody does…. The scale of light can be described by numbers—called the frequency—and as the numbers get higher, the light goes from red to blue to ultraviolet. We can’t see ultraviolet light, but it can affect photographic plates. It’s still light… Light is something like raindrops—each little lump of light is called a photon—and if the light is all one color, all the ‘raindrops’ are the same color… Every instrument that has been designed to be sensitive enough to detect weak light has always ended up discovering that the same thing: light is made of particles…” Richard Feynman, “QED : The Strange Theory of Light and Matter” 1985
“Just because things get a little dingy at the subatomic level doesn’t mean all bets are off.” Murray Gell-Mann

It is in the admission of ignorance and the admission of uncertainty that there is a hope for the continuous motion of human beings in some direction that doesn’t get confined, permanently blocked, as it has so many times before in various periods in the history of man.
