Dirac Lecture 1 (of 4) - Quantum Mechanics 

galileo ,archimedes too

@Fernando Cunha Doesn't matter. Dirac seems to be pretty old and timid here too. Only thing that makes these tapes precious is the fact that we get to see these great minds in the flesh

Bravo

Principia and the scrap books with an AI making facial expressions for his portrait. Not sure what accent he had but one of the English actors could supply the voice deep fake style

I'd rather see Heaviside, Tesla, and Steinmetz.

*great man

haha

It was probably an Heisenberg camera.

Amo la bellezza delle equazioni di Paul Dirac

improbability drive now it is

I'm watching this film because its Dirac, but if someone has taken the time to explain Diracs work for a particular educational outcome that makes them more than worthwhile. There is no such thing as an ugly person, just ugly behaviors that are learnt by people as the inevitability of the mathematical permutations that are generated by this universe.

Very true, indeed! I get such a feeling of revulsion, when a mediocre brain tries to convey a subtle, complicate concept in a shallow manner and distorts it by his ridicule commentary. I wish there were more videos of great philosophers and scientists on youtube, that talk with the appropriate gravitas and insight about intriguing themes! Interviews with Carl Jung and Bertrand Russel are gems of intellectualism I found recently, but are there any more?

Emily Dickinson disliked this

As long as they can explain the concept well, I couldn't care less who they are to be quite honest.

Andrew Tate > Dirac

James Benton Ticer Yes, indeed. Quite amazing to be able to see and listen to Sir P. Dirac in an actual scientific lecture. Many thanks R. Smythe for this gem of a video (in terms of historical / scientific significance).

Heinrich Kluver at the University of Chicago resided in Culver Hall with a biology library on the floor above his. He had 24 hour access to this library, When I went to UofC in the 1950's each department had its own small specialty library, many with with a lot of extremely specialized books contributed by retiring professors. The specialized physics in the Fermi building even had a librarian who could translate math and physics books from Russian and German into English. This library was open 24 hours to relevant physics staff. Unfortunately since then these departmental libraries were discontinued and their volumes buried into the vast graveyard of knowledge called the Regenstein library. There is no way these libraries where one could freely browse books related to your interest can possibly compare to relatively dead megalibraries.

I was a pure and applied maths prizes winner at a top school-one of the the prize book was a course of pure mathematics by G H Hardy who discovered Ramanujan and I did Engineering at university.But Dirac was learning about bricks and mortars at school let alone mathematics before doing engineering degree at Bristol university. Failure to get jobs at that time in engineering led him to do research in physics at cambridge. Rest is history. I think Richard Feynman was influenced by Dirac's thinking let alone physics judging from Feynman's admiration from the writings of Feynman notably from his : A character of physical law, So you are not alone. I learned from the writings of one of Dirac's maths students who used to take lectures at Cambridge on behalf of Dirac as a Phd student on electron spinning ,that Dirac hardly talk, a man of few words. I think it was because he was an engineering at heart unlike physics graduate since physics graduates are good talkers let alone hero worshippers unlike engineers.

kanvij I can tell that english is not your first language by the way you use the phrase "let alone"

Who cares about your opinion people like you might have failed ramanujan. In India yet he was talent spotted by hardy of Cambridge university a century ago.

kanvij thats was not an opinon that was a fact. And Im not a mathematician so i cannot "fail Ramanujan". if anyone fails ramanujan its sub-par mathematicians like you whose work will never be relevant no matter how many prizes you "top-school" gives you

What have you achieved in your life? I have rubbed shoulders with minsters from African countries and studied with Africans. My technical papers have been published for more than 3 decades.There is a shortage of English teachers go and teach English, if you are not good in maths you are in the wrong place. Good luck to you and don't waste your time here..

what ego at 80 y old?..

Only time he spoke more than a few words was when talking about physics. It is reckoned he had Asperger's syndrome which explains his shyness. Amazingly he had a wife and two children

He used to speak through research By publishing one of best research paper

Plato is a Greek short order cook and Newton is a Presbyterian minister. I visit them regularly.

hee hee...I had them locked away in the catacombs but the papyrus wore a bit thin...just like this comment!!

Alan Spector "Only the dead have seen the end of war" -Plato (His theory is holding up very well)

Sad but true. Aggression and killing.

I sent the video's back to Dirac warning of dangers of knowledge.

yes please do! carlo rovelli

Very good idea!

Did you cleanse it of the white noise in the passage of the last six years?

any luck?

It's been 8 yrs Stephen common man how lazy you can be.

This is amazing to have video and audio of him giving lectures. I hope you wouldn't mind if someone wanted to clean the audio and reload.

thank you for your contribution

Yep, exactly. I find many people, including myself being intimidated by Newton, who was so brilliant that he invented the math as and when he needed it but in reality, he was the exception here and that's what made him brilliant. Most physicists view mathematics as a toolset that you can learn if needed

True. While it's true that many physicists enjoy mathematics just for the sake of it, it's not universally true. For many people, it's much more intuitive to learn the "tools of the trade" (IE, mathematics) as you try to use them to solve problems that you're actually interested in. A greatly simplified analogy of this would be like teaching someone to work on a car engine. You could teach them about all of the tools they'll ahead of time (screwdrivers, drills, ratchets, sockets, etc.) and hope they remember them all, _or_ you could simply start working on the engine with them. As you encounter the things these tools are used to solve, their usefulness becomes apparent organically. "Oh, we need to take this valve cover off-- it's held on with 4 screws." Not only will the student implicitly understand what the screws are for, they'll quickly learn that you need a screwdriver to unfasten the screws. When you encounter a piece that's held on by maybe _50_ screws, then you can introduce the concept of a power drill with the proper bit. A more complicated tool, to be sure, but one that greatly increases the possibilities of what you can do. Some people just do better when they learn by _actually_ doing. Not waves of menial practice problems, but _real_ problems that they're interested in-- even if it seems like they might not have the proper framework of understanding at first to work on those problems in the first place. It's weird, but it's true. Some people prefer to learn about all of the tools first and that's totally fine. The problem is that there seems to be a gross under-representation of alternative teaching strategies (such as the aforementioned), at least in the US. If you don't fit the mold, then you're left behind-- even if you have a good (just different) mind. I'll leave the concept of who's to blame out of this, but it is unfortunate.

@@sasca854 Thank you for this long-winded reply (even longer than mine). I'm more of a quantum mechanic than mechanic - so when my car needs adjustment, I reach for my wallet while my car mechanic reaches for his screwdriver.

I agree, I am phd student of Physics.

My dad studied physics at Cambridge.

His book does a phenomenal job of motivating the postulates of QM from Hamiltonian mechanics.

Yeah I know what you mean... it's quite a magnificent thing, to have this brilliant man on film. A pillar of humanity's intellectual legacy.

youssef albanay not einstein?

That would be John von Neumann!

Nah! Eratosthenes and John von Neumann. There is always someone cleverer than yourself though. That's life.

Einstein's IQ was only 160. Both my parents are/were 161, so they smarter than Einstein.

but still sadly Einstein is much greater

Cedar Audio makes devices that can do that easily

Thanks for doing this!

You mean Henri Poincaré the original inventor of the theory of relativity which is a much bigger achievement than stealing it and relabeling it "GR" (einstein).
