From what I know of Dyson's reputation, he is a phenomenal mathematician; so it is both very great and humble of him to acknowledge Feynman's contribution to Dyson's own success; that is very admirable, the mathematics-applied-to-physics genius Dyson acknowledging the contribution of the overall-physics genius Feynman.

[@kdub1242]

John Uscian Yup. He demonstrated the equivalence of Schwinger and Feynman's formulations of QED, and made important contributions to the perturbative calculation of scattering amplitudes, among other things. I don't know a lot about QED, but some of the experts believe Dyson may have also deserved a share of the Nobel for his work.

[@calvinsylveste8474]

Too bad he could not overcome the influence of ingrained mysticism which corrupted his ability to reason.

[@davidr346]

The series of 157 videos interviewing Dyson are fascinating. I don't think there is any other source for what Dyson says in those videos. And he consistently gives credit even-handedly where credit is due. By far my favorite living scientist.

[@pratiksingh1714]

[@NothingMaster]

Dyson is always incredibly entertaining to listen to; a most gifted and engaging storyteller and mathematician. Feynman was a most creative genius and a natural born physicist. Although Feynman, the physicist, preferred to work with the pictorial representations of mathematical expressions, we should not forget that he was a mathematical heavyweight, as well. His groundbreaking work on the path integral formulation is a triumphant case in point. That said, Feynman’s creative mind was overwhelmingly preoccupied with new and revolutionary ideas and original insights and he opted not to spend his time working on tidying up the mathematical loose ends.

[@ddorman365]

Thank you Sir Dyson for your help and collaboration and support (great job on the mathematics!!:), I hope to see you soon, peace and love, Doug.

[@francoismorin8721]

Humble man when he talks about his collaboration with Richard Feynman. Wow that Feynman seemed like such a spirited human being. A genius he says, I am starting to believe he was a super genius to have mastered all regions of his brain, logic, artistic and emotional.

Feynman knew how to sell himself to the public with an image that was somehow farfetched from who he is in reality.

[@ienjoyapples]

Implying some were not.

[@cinskybuhsrandy5099]

​@@pardismack I think that's the last thing he would do. He didn't need to pretend and certainly he didn't care about his public image. He was an extrovert and liked to show off, but there's no reason to suspect that his behaviour wasn't genuine, from his uncompromising enthusiasm to his proto-trolling. Great part of the public interested in him were other scientists, usually very clever people, often very sceptical. Do you think they'd just buy it? Do you have something to base your claim on? If not, why would you do such a great man an injustice? Out of envy?

[@pardismack]

@@cinskybuhsrandy5099 Yes he was an extrovert but he loves talking about women to appear as a womanizer as that was somehow celebrated at that period of time but in fact he was a family man and he prefers focusing on his family and on nerdy stuff

[@JusNuncle]

Thank you for your contribution sir.

[@bestoutcomes]

I believe this gentleman is credible. His body language reveals sincerity. I particularly call attention to what he says about Feynman. Others who have videos on KZbin, featuring someone who claims to have "known" Feynman, show them -- when talking about Feynman -- putting him down and claiming he was self-absorbed, how much ego he had and how he tried to impress others with how smart he was, and just putting the man down incessantly. Which is inconsistent with 100% of the videos featuring Feynman himself. Whereby he exhibits none of this behavior they claim. Plus, much left out so as to deceive via omissions and commissions both. I have commented on those other videos but no one ever replies to challenge my assertions their guest is wrong. So, this is refreshing. To listen to him speak of Feynman about how Feynman actually was, rather than an erroneous perception due to some insecurity or having been a competitor who was outsmarted and embrassed perhaps by Feynman, who simplified their math and intentionally complex jargon. Anyway, this is a refreshing video.

[@Treviscoe]

@@readynowforever3676 Probably true about Freeman Dyson, but by his own admission (in "Disturbing The Universe") that wasn't his role, at least not in theoretical physics. He tidied up loose ends and solved problems in work other people had done rather than come up with original theories himself.

I love how he mentions Feynamn because he is underrated. He spoke much more majestically and a he had an appreciation for the mundane and exquisite alike. Einstein is somewhat an anti-hero or a villain he lacks the morals to be the poster boy for physics

[@johnwagner4776]

As a non-scientist, it's hard to understand why Dyson would say that Richard Feynman did the "hard work" when it was Dyson who had to develop the complex mathematical proofs.

[@6900xx]

I think it shows how humble of a person he is and that makes him more respectable.

[@bluemonstrosity259]

Feynman came up with the idea. Dyson described it mathematically. An analogy would be Feynman being the inventor of a product, Dyson being the guy who actually works out the ways to manufacture it

[@superroydude]

digxx It's not like Feynman didnt have a mathematical method to his theory. He devised a method that could carry out calculations extremely quickly and arrived to the correct conclusion. The problem was that his method was virtually incomprehensable to everyone else. What Dyson did was make feynman's theory mathematically rigorous by translating it into a language people could underatand.

[@smarajitpunaykanti6463]

[@NorceCodine]

The truth is Einstein hated Princeton, he addressed his letters as "Concentration Camp Princeton", and he refused to learn English. He only talked to the Mathematician Goedel in German (who starved himself to death in protesting the intellectual backwaterness of Princeton). Einstein realized, however painful it was, that the intellectual stimulation of German science made him who he was. The stillborn American social engineering at Princeton was a charade. Thats why he didn't achieve anything anymore, and he died a bitter man.

[@boydmccollum692]

NorceCodine well Einstein has only himself to blame - he didn’t need to stay at Princeton, especially after the war. It’s a bit of a cop out that he would blame Princeton for his situation.

[@LeandroFosque]

I like Dyson, but saying that the world is getting greener and therefore preserves biodiversity is misleading. Certainly rain forests are being destroyed, and therefore entire ecosystems are being extinct. They are getting replaced by monoculture, so they still being green from a satellite. The main problem is this kind of destruction, that is what people have to fight against first. The world needs a people that don't necessary believe in climate change, but fight against monoculture, population growth, the destruction of biodiversity, and contamination. Since the real crisis is energy.

[@jccusell]

+Frank Zaka Why is this a crisis?

[@soulscanner66]

Climate change is not a belief. It's an observation based on data. It's causes are a question of well-tested theories and predictions confirmed by yet more accurate and complete observations and data. The loss of biodiversity and its causes are similarly a question of observations.

[@jccusell]

Could you point to someone or an article that claims that climate does not change?

[@hansenchen1]

+Guy Souriandt: Your claims are way over-blown. It is a speculation based on some data, and with huge amount of assumptions at that. With that amount of assumption, particularly the vehemence with which most the supporters preach climate change without rigorous scientific deduction and proof, it is not too far from a religious belief.

To watch a real teacher, Richard Feynman is the best... because he makes it fun... doesn't give long drawn out explanations.. short concise explanations are his forté... he also translates from metric into American... we call it the Imperial measurement system... the Brits went metric long ago... it's American... because he knows the young folks in his audience don't understand metric.... Ronald Ray-gun locked us out of the metric system by saying the little dears would be confused by learning 2 measurement systems... his Alzheimer's riddled brain leads us still... that's why everyone thinks math is hard.. fractions are.. that's all they know... after 30 years, I finally got through to my wife, who says she doesn't understand metric.. it's because she doesn't understand American either, and I kept saying... if you can count to 10 you understand metric... finally, I told her... it's like making change for a dollar... bingo... every kid in America learns that before school even... far out man!
