Such a marvellous sight of conversation. I can't believe how bright and sharp Dirac is at this age answering every question that Friedrich posed very eloquently.
Good Morning: Is that Norbert Dragon speaking? It's because only Norbert Dragon of Karlsruhe & Hannover, John Singh from Ireland and maybe Jürgen Ehlers are the Ray Experts here!
@birdman4274 This is conjecture on my and many others part, so take this as you will, but as someone with ASD it appears clear to me that Dirac had a form of Autism or other such disorder. The way his mannerisms, behavior, thought, speech, everything he did and how he went about it tells me his 'eccentric' nature came down to not only how he saw the world, but interacted with it as well. I have no proof of these claims (Dirac himself I believe was never tested, nor gave any personal account therein), but from an outside perspective with firsthand insight into the nature of ASD I would confidently say Dirac was on the spectrum, as I've found similar occurrences in other major mathematical minds. Perhaps I am well off base and he was simply an intelligent man who could not connect with people due to his personal understanding of human nature and the world at large, but to me that is a moot point considering his other behaviors (reclusivity, very little speech unless he "had something meaningful to say", particular routines (I believe he had even scheduled his walking/thinking time and stuck to it religiously), et cetera). I simply believe these factors are the cause for many people viewing Dirac as strange, eccentric, weird, and above all intelligent. He had such a beautiful mind and the world is left not only better due to his legacy, but also worse because there has not been another great mind like his in decades. RIP P.A.M. Dirac
How extraordinary to be able to hear a sampling of how a seminal figure like Dirac perceives and contemplates the foundations of our theoretical understanding that he helped to create. Hund is a pleasure to listen to as well, still displaying a boyish delight in the discoveries.
I read about quantum physics, trying to understand the concepts, but I'm not educated enough to be able to understand the mathematics. Hearing Dirac put his knowledge into words is quite amazing and interesting for me. I never expected he'd agree to be interviewed and filmed!
@@wargreymon2024 He was always like that, just read his story, the act of talking was a lifetime trauma to him, because his father would spank him every time he missed a word gender or verbal time (his language is French). When his brother commited S, he said "i didnt understood why my parents were so sad at the moment, but later on i understood that this is a normal thing" because he literally never understood the concept of love. His friends created a meme constant called "dirac constant" that represent 1word/hour.
@beniocabeleleiraleila5799 I came to the comment section just to see if someone mentioned the 1 word per hour dirac unit. Dirac was also married to Wiegner's sister.
I'm really not surprised he lived so long he looks in much better shape than Dirac here, I thought he would have been the younger one. Dirac died just 2 years after this interview.
Oh my God, what a wonderful video! I am so greatful finding here on this channel! It is really amazing! And the two interview partners are absolutely divine, both Paul A. M. Dirac and Friedrich Hund! ❤❤❤✨️✨️✨️🍀🍀🍀✨️✨️✨️🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻
Dirac, this shy genius, perhaps spoke a lot more during this interview than he had spoken during his whole previous life. With his silence and dedication he made humans a better species.His work and contributions to quantum physics will be taught for several thousand years from now.
Wow.... is he Dirac....? Is he...? What a wonderful world I can see one of the great guys in physics history like this... I was thinking it's his very old days considering his pictures in many books, but... after searching, yes, this video was recored just 2 years before he died...
It's interesting to observe how the concept of symmetry has changed subtly since this discussion. Dirac is talking about a symmetry between space and time as though these are two different things having a connection whereas these days I think we regard space-time as a continuum and the symmetries we talk about are 'internal' symmetries as understood by Noether.
Unlike what today's "thinkers" seem inclined to believe this video shows that real great thinkers didn't need to speak fast in order to prove their points
Dirac was famously taciturn. His colleagues at Cambridge coined a new unit "the Dirac" as the minimum needed to partake in a conversation, a "Dirac" was one word per hour.
Such a lovely and profound interview! Two great minds discussing the nature of the universe and life. The humility in conversation, where both men are so aware of what they don't know! So RARE to see in this age of social media where opinion is presented as fact!
Fun fact: Back in the Leipzig days, when Leipzig was the world's epicenter of theoretical physics, Heisenberg and Hund did a series of shared lectures. It was called "Heisenberg mit Hund" (literally: "Heisenberg with his dog"). It was a well received event and probably of greater impact and reputation than Feynman's lectures later. The title was a pun in German, but it showed that Heisenberg outranked anybody at the institute.
I wonder whether Douglas Adams was thinking of the Fine Structure Constant when he wrote about the ultimate answer to life, the universe and everything.
Here, it is about how the both undoubted and esteemed Peers are in fact recalling the ways of how the Professional Mankind could aptly circumvent the over-all ignorance as to some important points to nonetheless duly succeed with all their epistemic exercises, however, still without clearly answering important basic posers. A very nice illustration of the general trend... Many sincere thanks for posting this!
Hund discovered the so-called tunnel effect or quantum tunneling and Hund's rule of maximum multiplicity....First discovery is a simple description of interaction of charged (magnetic) particles at the proximity and the second discovery is a simple energy law related to the thermal motion of atoms/ions/molecules in the closed volume adapted to the spin possessing particles...these rules are naturally appearing in the mind when posing correct questions and knowing what electron is
at around 15.30 to 16.00 Hund talks about Dirac large numbers 10to40 and 10to80 but the subtitles wrongly show 10to14 and 10to18 . An auto generation confusion and sometimes non-natives too.
Paul Dirac, one of the most brilliant minds in history. Yet he's talking about Einstein's brilliance. Shows just how much Einstein (like Newton) were in their own class.
This is what going to the source means and why it is important; words directly said by the speaker instead of relying on the words of another who claims to have witness this talk.
This is what it looks like when 2 people care only about the science. Not about correctness, politics, reputation, etc. All that matters to them is what Feynman once said, "It does not matter if a theory is elegant. It only matters if it's actually going on in the real world." (I may not have the exact wording). These 2 brilliant men only cared about describing how the universe actually operated.
A lot of this is, obviously, well out of date. The introduction of the Rockwell Retro Encabulator saw an end to such esoteric discussions between intellectual giants, largely as a result of the malleability of the hydrocoptic marzelvanes and the logic output of many differential girdlesprings into the college undergraduate physics syllabus.

Dirac "I wanted to emphasize that Einstein was the first to realize the importance of symmetry". I feel there are pillars of thought that Einstein is missed with credits. He is commonly referred to as a founder of quantum mechanics, but I would say that 1) realizing symmetry led to QFT, where fundamental forces are described as quantum gauge theories, 2) he was the first person to quantize a particle by turning light into photons, and thus photons were the first particle with quantum particle-wave duality, 3) he was the first to comment that solutions to Schrödinger equations can be viewed as a probability distribution (Max Born heard him and took him seriously) and so effectively discovered quantum superposition, 4) he effectively discovered quantum entanglement in 1935 while trying to disprove quantum mechanics. I might just argue that particle wave duality, superposition, and entanglement are the 3 most fundamental properties of quantum mechanics. And that gauge theories somehow describing the fundamental forces of electromagnetism and strong or weak nuclear forces is perhaps what is most fundamental of QFT. Einstein discovered all of the most fundamental ideas of both QM and QFT. Every physicist of the 20th century-- even pioneers of QM and QFT-- essentially just built on and further developed his "passing" ideas that he thought little of.
Well put. And that’s only regarding quantum physics. All of that is in addition to his pioneering work in various other fields in physics culminating in his general theory of relativity, one of the greatest achievements of the human mind. Then come along some people who know next to nothing about physics or any of Einstein’s monumental discoveries, and say Einstein was overrated because they read some ridiculous mambo jumbo about him on the internet. If anything, Einstein was underrated.
A bunch of made up hooey. Max Planck was the originator of quantum theory, he was the first to suggest energy was quantised instead of continuous. It’s ridiculous to suggest every physicist’s work in quantum theory was built on Einstein’s passing thoughts. There are numerous other brilliant scientists who had original thoughts and produced original work in the quantum - for example, Niels Bohr and Ernst Rutherford and their quantisation of the atom
Einstein was unique in a way that for some reason he produced top notch cutting edge papers for more than twice as long than any other physicist we know. Interestingly enough, he received exactly 1 Nobel prize despite the fact that all 4 contributions of 1905 were in itself all Nobel-worthy. He came up with relativity by himself when 99% of physics was just focusing on quantum theory and nobody was interested in another theory of gravity. He helped the "quantum clique" with complicated calculations and often did hideous matrix calculations for Born and Heisenberg in Heisenberg's matrix mechanics when they were overwhelmed with work. He described and conceived the L.A.S.E.R. in 1916. Had he lived a few years longer until the first laser was built, he would have been awarded a second Nobel prize for that. And around the same time the first sophisticated tests of special relativity and general relativity were carried out as well. Had he lived, there was no way Stockholm could have not awared him another 2 Nobel prizes for the proofs of special and general relativity. Instead he had to be nominated more than 60 times to be even considered for one Nobel prize because the chairman of the Nobel committee at that time was an eye doctor and did not understand Einstein's contributions. So he did not agree to honor him with the prize for many many years, and because said eye doctor disliked relativity in a similar fashion, they had to go back all the way to 1905 and randomly (!) picked one of the other 1905 papers for the Nobel prize. That's actually a true story which was investigated and solidified by sources and evidence only fairly recently. Oh and he autodidactically learned tensor calculus, coined the term tensor analysis and introduced it to physics when publishing general relativity. I agree, technically speaking he is underrated because he published so many things which typically go unnoticed by laymen and conspiracy idiots, even though he is always depicted as THE archetype/blueprint of THE genius.
@@bobbwc7011 Nobel worthy contributions by Einstein, as have emphasized is correct. Here is one more: Bose - Einstein condensation predicted in 1924 that came to reality in 1996. S.N. Bose, Einstein & one from the two experimental projects should have been nominated for that, but the three experimentalists Cornell, Wieman & Ketterle received the prize in 2001. Your last passage is a noteworthy one, specially about the "conspiracy idiots."
I like the fact that they hope to get unified theory pretty soon. I started reading about this topic in the 90's and physicists hoped we will get the theory soon after year 2000. Now over quarter in the 21'st century we are still nowhere near.
We haven’t had anyone like Paul dirac or people on his level since then. People now have become more selfish. The brightest people just take a medicine, computer sci or engineering degree just to make money. The culture of contributing to Physics and it’s natural philosophy is dying. I guess it makes sense for a subject like physics which won’t technically bring personal benefit. Sad.
If anyone fancies a nice deep dig into the biog of this wonderful human being, I recommend Graham Farmelo's book, 'The Strangest Man'. Somewhere in the book's notes, you'll find a formula Dirac invented that totally ruined a college mathematical game for good.

A bunch of made up hooey. Max Planck was the originator of quantum theory, he was the first to suggest energy was quantised instead of continuous. It’s ridiculous to suggest every physicist’s work in quantum theory was built on Einstein’s passing thoughts. There are numerous other brilliant scientists who had original thoughts and produced original work in the quantum - for example, Niels Bohr and Ernst Rutherford and their quantisation of the atom
Einstein was unique in a way that for some reason he produced top notch cutting edge papers for more than twice as long than any other physicist we know. Interestingly enough, he received exactly 1 Nobel prize despite the fact that all 4 contributions of 1905 were in itself all Nobel-worthy.
He came up with relativity by himself when 99% of physics was just focusing on quantum theory and nobody was interested in another theory of gravity. He helped the "quantum clique" with complicated calculations and often did hideous matrix calculations for Born and Heisenberg in Heisenberg's matrix mechanics when they were overwhelmed with work.
He described and conceived the L.A.S.E.R. in 1916.
Had he lived a few years longer until the first laser was built, he would have been awarded a second Nobel prize for that. And around the same time the first sophisticated tests of special relativity and general relativity were carried out as well. Had he lived, there was no way Stockholm could have not awared him another 2 Nobel prizes for the proofs of special and general relativity.
Instead he had to be nominated more than 60 times to be even considered for one Nobel prize because the chairman of the Nobel committee at that time was an eye doctor and did not understand Einstein's contributions. So he did not agree to honor him with the prize for many many years, and because said eye doctor disliked relativity in a similar fashion, they had to go back all the way to 1905 and randomly (!) picked one of the other 1905 papers for the Nobel prize. That's actually a true story which was investigated and solidified by sources and evidence only fairly recently.
Oh and he autodidactically learned tensor calculus, coined the term tensor analysis and introduced it to physics when publishing general relativity.
I agree, technically speaking he is underrated because he published so many things which typically go unnoticed by laymen and conspiracy idiots, even though he is always depicted as THE archetype/blueprint of THE genius.
@@bobbwc7011 Nobel worthy contributions by Einstein, as have emphasized is correct.
Here is one more:
Bose - Einstein condensation predicted in 1924 that came to reality in 1996. S.N. Bose, Einstein & one from the two experimental projects should have been nominated for that, but the three experimentalists Cornell, Wieman & Ketterle received the prize in 2001.
Your last passage is a noteworthy one, specially about the "conspiracy idiots."
This is excelent essence material! Much oblige
How does this only have 270,000+ views?? How??
A Dirac: a unit of silence. The least number of words that can be spoken to convey an idea.
8:44 my life goal: to find a friend to have conversations with where eye contact is optional. ❤
The guy is still very sharp ...great interview and insight 👍
Seeing them in video is amazing experience....only heard read their names in books....they are blessed by god
what did we get from that radar deal?
You can hear the humbling with his words...
I like the fact that they hope to get unified theory pretty soon. I started reading about this topic in the 90's and physicists hoped we will get the theory soon after year 2000. Now over quarter in the 21'st century we are still nowhere near.
We haven’t had anyone like Paul dirac or people on his level since then.
People now have become more selfish.
The brightest people just take a medicine, computer sci or engineering degree just to make money.
The culture of contributing to Physics and it’s natural philosophy is dying.
I guess it makes sense for a subject like physics which won’t technically bring personal benefit. Sad.
Paul Dirac a true genius 😮😮😮
If anyone fancies a nice deep dig into the biog of this wonderful human being, I recommend Graham Farmelo's book, 'The Strangest Man'. Somewhere in the book's notes, you'll find a formula Dirac invented that totally ruined a college mathematical game for good.
wow, what a fantastic discussion.
Now I wonder whether the questions about the mass ratios between proton and electron and other particles were ever settled.
Gentleman geniuses modest to the last. Where are they now?
