I wish all KZread videos were like this. Jam packed of content. No waffle, straight to the point. Clear and concise

"I will tell you about quantum electrodynamics without math, so my explanation will be necessarily incomplete. But I promise that my simplified explanation will not tell you anything that I would need to retract in a more detailed explanation." ~ Richard Feynman, opening a Cornell University on QED for a general audience.

This guy is amazingly articulate.

feynamn.. One of the greatest men to ever live.

It's funny -- my friends in college all love Feynman because he's so easy to understand and because he explains things so elegantly. For the same reason, my physics professor is a bit intimidated by Feynman because he knows it takes A LOT knowledge and skill to be able to explain something so complex so easily.

Feynman's careful discussion of complex topics sets an absolute standard for truth, clarity, and respect for his listeners.

A man with a great mind using his brilliance and imagination and comparing his thoughts to a chess game. Feynman was called in to investigate the 1986 Challenger Shuttle disiaster. He often had 'seminars' with ordinary people just to hear their ideas, expand his mind and challenge science. He was one of these people who had incredible intelligence and yet could explain the most complicated of subjects in a way that anyone could understand. True genius and a lesson to us all. Sadly RIP.

holy shit! it's castling!

It is so rare in history that we see someone who could explain things the way RF did. Greatest teacher and explainer.

I'm glad there are people like Feynman.

I miss this man, he was brilliant. RIP Feynman

O man, just how i wish he is still with us today. Just look at the joy and fire he has when he talked about physics, you can tell that he really enjoy science. Feynman is always my favorite physicist and scientist. Good job Mr. Feynman.

Bravo indeed! Plain words to explain deep things... A very great joy to hear Mr. Feynman talking physics!

Wow, such a good analogy.

Thanks.

The world needs more people like him...

There's a BUNCH of Feynman audio around -- look for Los Alamos From Below and the audio of "Perfectly Reasonable Deviations from the Norm," --- letters, wonderfully read. Tuva Trader has Ralph Leighton's recordings of Feynman telling stories and both drumming together on 4 CDs (and you should read the books that came out of those sessions, "Surely You're Joking, Mr. Feynman," & "What Do You Care What Other People Think, whether you think you like to read or not!"

I love this metaphor so much.

The audio is in sync with the video! Yay!!! Absolutely a legend!

Such a good explanation of the way science works in my opinion.

I think it was Dirac who originally used the chess metaphor.

An excellent exposition of Scientific method by a brilliant scientist.What I loved most about Richard Feynman was his playful sense of humor and practical joking:safecracking at Los Alamos and deliberately leaving classified documents lying around for a laugh.Must have been a headache for Security folk.The safecracking mullarkey just cracks me up.

i like watching all these casual Feynman interviews, but now i have ran out of them, will have to turn to his lectures to continue listening to him :/

You and me both. I've started on Richard Feynman on Quantum Mechanics (Parts: 4). Sure would've loved to have had him as a lecturer.

Scientists figure out the rules... engineers get to play the game.

wow! some great analogy!

Had I watched this video some 6 odd years ago, the likelihood that I would have chosen physics as my major would certainly be higher. Physicists of the world, you have my envy and admiration. Keep on trucking!

Feynman is the BOSS

Fantastic!

he makes it all seem so simple

I think it was Feynman who said (something along the lines of), if you can't explain it to your grandmother, then you don't truly understand it.

this man gave me a new angle on how science works in under three minutes. it's one of those things where you sort of know it but lack the words or analogies to fully express it. that's what he did for me, with the bishop analogy. the bishop moving on a diagonal EXPLAINS why it preserves its color, just like newton's law of gravitation or einstein's explanation of curved space-time EXPLAIN why planetary orbits sweep out equal areas in equal times. but in physics, the rules get simpler. *sniff*

Very elegant for even those who don't play chess can get i!

haha he's just explained so easily what i often tried to put into good words, that what seems to be a complete formed law, is actually just say, a symptom on the surface of something infinitely more complex.

brilliant, brilliant and one million times brilliant!!!!!

Surely, you're joking Mr. Feynman.

Feynman is the best teacher ever!!!!!!

What a briliant man!

I was thinking the exact same thing :)

A theory of everything!

HELP!!!!! I'M IN LOVE WITH A DEAD MAN.

brilliant!!!!!!!

This is why it always makes me angry when scientists are accused of ignoring facts that don't fit their theories. Sure, it happens sometimes, but it's contrary to the very nature of science. For a true scientist, the thing that doesn't fit is the most interesting one of them all.

Absolute Genius

i think the video is great

amazing... :)

This guy gets it...

Great clip dude!!!

wow.

I miss Feynman

The audio is in sync with the video! Yay

@renumeratedfrog "Fire on High"

There is a book that takes the mystery out of chess, it's call the Collier's Quick and Easy Guide to Chess, written in the 1950's. I'm serious. It teaches the simple Principles of Chess in an understandable manner. It teaches a style similar to Bruce Lee's Jeet Kun Do, (the Way of the Stopping Fist). Take the initiativeea by thr and kept it.

what he said is true its reality of humans life....

If any actor chooses to play the part it should be Clint Eastwood. They have such similar mannerisms and that sly grin just grabs me. What a genius and such a great sense of real humor, too.

@dvide wow

this guy is the fucking greatest, not one of my teachers come close

People who say KZread is just stupid videos should see that. I get so much interesting information just browsing this site! + I can watch funny puppies doing funny stuff (-;

I think only Feynman could use chess as an analogy which is supposed to be simpler than the concept you are discussing and then at the end tell you it's really the other way around and it actually makes sense.

What a Noo Yawkah. :)

@Every1Tubes Different strokes, eh?

@enijize1234 it was Albert Einstein who said that!!!!

i guess the world is more like go than like chess :)

I wouldnt promote to a bishop LOL

perhaps that the rules don't seem to change implies that the game has been fully defined. if that is so, then perhaps that implies that the entire rule set can be known. in this case we will most likely one day know the entire rules set of (the universe) chess. alternatively, if the game is still being defined, then we should expect the rules to constantly be changing (which they are not).

I thought it was, if you can't explain it to a freshman class, then it's not understood.

physics seeks a simplicity.. it is anti theatrical... see brecht on this

He had the passion of women but he wasn't a gigolo. First of all he loved life and in life Physics.
