He's so precise in his dictation that sometimes I play a drinking game where whenever he says something like "uh" or "anyway" or "well, ... " I take a drink. It's usually hard to get a buzz going.
Consider how many towering intellects are trapped behind incoherent, autistic rambling. That's the unique genius of this man: crystalline public interface.
He said himself his first subject he was most interested in and studied was linguistics, which makes ton of sense by the way he speaks and forms his sentences.

Edward Witten is a master speaker. In his entire talk there is not a single "eeh" or "umm", or any other disturbances that creep into normal peoples speech. A pleasure to listen to.
It is so refreshing to listen to professor Witten, speak in terminology that is clear and understandable to delay person. So often in his mathematical lectures, he can speak for over an hour long, and I am unable to understand a single sentence in the lecture.
Always pictured Witten as a sort of Ivory Tower figure, solemnly churning out technical papers. Turns out he is actually a terrific engaging communicator.
His public speaking skills are made even more impressive because hes most likely autistic. You can see it in his mannerisms in the 1 on 1 interviews. His body language is very stiff, he always Is looking down at the floor avoiding eye contact.
He's an incredible mind. The closest thing we have to Einstein (albeit not quite at that level) imo. True genius. He studied history and journalism too; i think he may have dabbled in linguistics as well. He seems very well read.
Maybe it's just me, but his voice and articulation are almost soothing when wearing noise-cancelling headphones. I could comfortably fall asleep listening to him speak - that's meant to be complimentary (for the record).
Not so sure about that. Many modern-day physicists are surprisingly ignorant about basic philosophical issues and you cannot really be considered smart, let aalone the smartest, if you lack a solid philosophical foundation upon which you base your reasoning. On the other hand, if you only have in mind formulaic and mathematical smarts then a large number of mathematicians would have to be in contention for the title.
Absolutely he should. But don't bet on it. People are WAY too damn stupid to fully appreciate people like him. Instead, they'd rather look up to the Kardashians.
I read an article about Witten in the 1980's, I think. It may have been in Discover magazine. The writer said that when very prominent physicists met him for the first time, some of whom thought they might win a Nobel eventually, they just gave up on the dream on the spot. They realized that Witten was so far ahead of them that they didn't stand a chance. This would happen at dinner parties!
I would suggest watching the excellent NOVA series called "The Elegant Universe". It's a big time commitment, but it will prim you for Witten-level talks.
John Mitchell Do you have an idea what will prepare me? cause i want to be prepared to understand the near future if only to join the existential crisis that follows :P
twistedmezelf Sorry late for the reply but you'll need a lot of maths mainly in the fields of Algebra which includes Abstract, Linear and Lie Algebras lots of Algebraic Topology and Algebraic Geometry and sound understanding of Manifold Theory and Lie Groups and that just the Math part. For the Physics prerequisite you'll need sound understanding of Graduate level Physics which involves lots of GR and QFT , after that you can sufficiently ( although with a bit of hassle here and there) understand Wittens work on M Theory and follow papers from other great string theorist like Nimbu, Sen and Randall.
The audio levels change when he approaches the "live" microphone at the podium - while still using his wireless, lapel microphone. Does anyone notice this in the auditorium?
What I find is he is so easy to follow. I don't know if this is because of his unusual delivery which I first found slightly jarring but now is actually just really nice to listen to. Even compelling. Really interesting and brilliant guy.
I agree: I have much more respect for Dr. Witten after viewing some of his videos, mainly due to his clear and logical descriptions of the history of physics, but I still believe that "string theory" is bunk .....
Newton is in a class all by himself. There can only be one first. He was the primary builder of modern physics. He also did practically all of his work by himself, and the bulk of his work in a two year span. To top it off, he spent most of his time with alchemy and looking for secret messages and codes in the Bible. Who knows how much more he would have discovered had he devoted his entire life to science.
@@psybin Maybe, but in science it is common to show the science and not the presenter, since the facts are important and not the guy. The guy is anyhow well known from one picture at the start, but the formulas etc. are important.
Some 20 minutes in, Ed begins to describe how every path a particle can take is possible -- if not necessarily probable. Perhaps one way of explaining this is to say that "Everything in the Universe connects to everything else." Essentially in each and every "instant" of time (understood as a "moment of change") all universal influences converge on the particle -- a particle which itself is in unity with all other particles. The law of efficiency simply summarizes all such influences and 'determines' the particle's path through the greater unity of all things. Of course, this explains why the double-slit experiment gives such surprising results. The investigator's presence is also a factor. (A presence that itself does not exist in isolation from all things either...)
@13:37 "You couldn't get any credit for scientific ideas nowadays. But apparently in the 18th century you could." ----------> Since gravity is space-time curvature a 'graviton' would be a 'cube' of Planck length in the smallest unit of time imaginable. It won't be a particle or a string. That's why the 'graviton' wasn't discovered or observed at the Large Hadron Collider. Thanks.

People like him make me proud as a human. Thanks, Edward witten for your hard work.
The greatest mathematical physicist of all time. No doubt about this. He is frightening like hell. The way he writes equations it appears as if it is some joke for him. The kind of math he knows there are very few people who can come close to witten.
This comment is so stupid! Largely because it idolises and isolates what is significant from the rest making the assumption that the rest lacks the required knowledge or propensity for that knowledge.
We are all here because of the funnel theory. We started at Joe Rogan interviewing Eric Weinstein and were immediately funneled through RUclips where we each clung to a Witten video probably predetermined initially by the RUclips algorithm and finally our personal preference for the length of the video.
I've always wanted to give him a hug. Edward witton is my hero from since i was a small child. I love how he explains the most complex concepts. His books are even better.
Very interesting BUT... I wish people who make these videos show the SLIDES that the commentator is continually referring to.. WE all know what the speaker looks like but the information on the slides is often not displayed either at all or only for a brief time... Sooooo pleeeez let us see more of the slides......................
I wonder if we could have a three-dimensional random quantum geometry to get closer to a four-dimensional random quantum geometry (involving space and time). Wouldn't that 3 dimensional theory be an upgrade from String Theory which is a two-dimensional random geometry?
Yes brilliant math work. But string theory has a lot of problems. There's still no way of testing the theory, and the Standard model is basically complete - including all evidence of existence being of > 5 Sigma significance. The untestability says something about a theory. The math, as said is brilliant and Witten just saw the common components of 5 different string theories and combined them into one (Due to the complexity it required a mathematician with extreme intelligence to solve). That is pure math magic and has nothing to do with presenting any evidence or proof that string theory is correct. Bottom line: Witten made string theory "Elegant" with M theory, but that does in no way prove it - it is still likely it is completely wrong with respect to what it represents.
Wonderful! Oh, my _____ The observation of quantum entanglement may be our hint into the 4 dimensional geometry we seek. The geometric structures we do perceive are viewed from a higher dimensional vantage point. We are viewing entanglement from a dimension below the state this phenomenon exists in. Perhaps it is more a palindrome than a rhyme that can be used to see the commonalities from the inside out. Any entangled pair may be the pushpin or anchor. Any entangled pair exist at the same "place" in 4 dimensional geometry. The Delayed Choice experiment may be our access point.
When Witten jokingly remarked that De Maupertuis thought the principle of least action proved the existence of God, I was expecting the audience to react. The fact that they didn't is a little unsettling.

' On the Shoulders of Giants' ? Edward Witten is undoubtley the greatest living theoretical physicist of the World. But it is overstatement to compare him to Isaac Newton. At least until his M-Theory will be proved a true physical theory. If ever...
I do appreciate what an intellectual supergiant he is but it's telling that he's won the Fields Medal but never been awared a Nobel Prize. He's more of a mathematician than a physicist.
Is there am age where you are to old for this to have an effect or does your age not matter?? Also how do you find out where the moon was when you were born? How do you determine when you should be saving your self and how long does this period last??
So, you know how time is supposed to be a straight line, with the past, present, and future all happening one after the other? Well, some people think that's not true. They think that all of time is happening at the same time, and that we're just experiencing it one moment at a time. I find that idea really interesting. Imagine if you could travel far out into space and look back at Earth through a powerful telescope. You could see the past! You could watch the dinosaurs roaming the Earth, or the ancient Egyptians building the pyramids. The farther away you went, the further back in time you could see. You could watch the whole history of the world unfold before your eyes. But what about the future? Could you see the future if you traveled far enough away? I don't know. But it's a fun thought to imagine.
Who else is here from a Joe Rogan podcast? I'd love to hear more lectures from this man. The way he describes physics with ease is kind of relaxing.
You got me. I just had to see for myself. I hope my brain doesn't explode.🤣
