- Richard Phillips Feynman was an American physicist known for the path integral formulation of quantum mechanics, the theory of quantum electrodynamics and the physics of the super fluidity of super cooled liquid helium, as well as work in particle physics (he proposed the Parton model). For his contributions to the development of quantum electrodynamics, Feynman was a joint recipient of the Nobel Prize in Physics in 1965, together with Julian Schwinger and Sin-Itiro Tomonaga. Feynman developed a widely used pictorial representation scheme for the mathematical expressions governing the behavior of subatomic particles, which later became known as Feynman diagrams. During his lifetime and after his death, Feynman became one of the most publicly known scientists in the world.
Khan academy brought me here.
I really like the way he speaks, it's like a melody.
Feynman wasn't afraid to talk about the mystery behind the nature of nature and how little of it we really understand. This was decades ago, but it feels as if he's talking to us today (but from the moon).
Wow. The moment he started talking about static electricity over a distance and how touch is limited in range because it's just more neutral, everything clicked. Not one person has helped me make that connection between everything on a large scale until now, and I'm halfway through a physics degree D: I need to read more of his stuff... It takes a true genius to explain complicated things in the simplest terms, and he was definitely one of them.
When Feynman was talking about the force of electricity being greater than the force of gravity he was trying to explain the difference in scale (e.g. a number with 38 or 40 zeros behind it). I heard another person try to explain the difference in scale in this way.
You can tell he truly loves physics by the smile he had throughout the explanation!
Nice that he mentioned Maxwell . A man who should be mentioned along with Newton Einstein & Feynman .
He seems like a wonderful, insightful gentleman. We were lucky to have him. 🙏
Don't underestimate how difficult it is to just sit and speak continuously about physics without misspeaking from time to time. This is an unimaginably brilliant man. He's not confused..he just has trouble translating sometimes. He meant motions within the copper wires. The potential field is what initially drives the electrons. The magnetic field is just a relativistic effect of the moving charges, but what he is saying is right too.(aside from the initial wording)
Finally!! A quality production with no annoying, distracting background music! Thank you for this.
Excellent, excellent, excellent! He really thought these things through!
It's only coppah!
I read his book Surely You're Joking Mr Feynman when I was 13 and I absolutely loved it. I still marvel at the wonderful GENIUS this man was!
Thanks for this! Feynman is so special to be able to explain and help us understand without endless math!
Kahn Academy brought me here … what great analogies!
Can't believe this interview happened on 1983.
How awesome would it be if Feynman was alive to make videos with Brady??
Agreed...I've only just discovered these youtube videos. What a priceless set of vids!
The perfect combination of entertaining and brilliant!
I will never look at my e-cig the same way again.
