​@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

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.

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.

@bobbwc7011
@bobbwc7011 Год назад
Poincaré was a bitter, stereotypical frenchmen, who never got over it that Einstein killed it and put all the pieces of the puzzle together before him, despite the fact that he had worked on the topic for far longer AND DID NOT unterstand what he was doing or what nature was doing. He left no chance unused to belittle and despise Einstein afterwards, pushing his narrative despite the fact that you can clearly see in his papers that he was beating around the bush without getting the physics and without having the mathematical capabilities to understand the abstract meaning of the formalism. Whatever Lorentz said or didn't say, they did not come from Poincaré and Poincaré DID NOT understand them until way later. That was another thing to deeply dislike about him: He was a Monday morning quaterback. After Einstein conceived special relativity and even introduced the Minkoswski metric without noticing it at that point, suddenly Poincaré claimed that all of it was so easy and so clear and so apparant, especially to him. Typical unlikeable idiot.

17:41 renormalization technique inadequate I wonder whether Weyl’s invariance addresses this inadequacy that Dirac raised.

Mr Dirac mind was a fantastic one and so sharp at his age, he has been at the forefront of Physics, however his reaction to R. Feyman QCD theory and renormalisation was however a bit conservative and "cold".

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.

But don't forget Emmy Noether, she developed the symmetry & conservation forces principle in 1915 ~1918 in Germany.

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."
