Here I am, an MBA student at Lehigh University specializing in data analytics, more than captivated at a lecture over 40 years old: a lecture that is so much better than any I’ve had, ever. What an incredible teacher.
Yes, calling Einstein crap is a bit strong. His only major error was his “cosmological constant”, of which he termed his ‘greatest blunder’ There’s a strong temptation for people to welcome every claim that all historical discoveries are mistakes but if the maths holds with observations, we should accept theories that stand testing as with Einstein
@@DavidMcMillan888 That is not true. You can find a much more serious mistake in his photoelectric effect paper. It's just not well known, but it is very easy to spot.
I have never heard a better teacher: one of the most brilliant minds ever, but perhaps his true incandescence was his ability to comprehend the layman's mind and make this bizarre world accessible to many.
He was a teacher of teachers. Esteemed university professors used to drop what they were doing and gatecrash his lectures, listening to the Master as if they were hearing concepts for the first time.
His true beauty was that he HAD a layman's mind, just one that worked to see more clearly, and one that would accept everything exactly as it was, not as he wished or assumed it to be.
@@oogba71 I didnt say he was a bad teacher. Just a useful idiot. Thats what Tesla said about Einstein and all his ilk. I trust Tesla. He's right about everything. Einstein was an establishment pawn just like Feynman. Both idiots. Both wrong. Both guilty of crimes against humanity for lies and deception of the highest order.
One true sign of genius is the ability to take an enormously difficult topic, like quantum physics, and simplify it to such a degree that most people, who are not scientists, can begin to understand it. Yes, teaching is just as important as discovery. Professor Feynman rips apart the false adage 'if you can't do, teach.' Of what use is to have the gift of discovering great ideas if you don't have the gift of communicating those ideas to others? Professor Feynman had both of these extremely rare gifts. Truly a giant.
I've never heard an obviously highly intelligent person say "I don't know" so many times in a short time. He comes across as a friend that genuinely wants you to know. Brilliant and lovely. Greatly missed.
Feynman saw with great clarity and let his audience in to that clarity with the logic and simplicity of his presentation. The result was the best teacher of physics. Ever.
Thanks for your comment you my friend have also describe him with simple words and elgant precision, so he most probably be proud of every one of us for listening his lectures wondering like little kids and trying to comprehend this awesome and complex universe apparently govern by statistics......😁👌
What a wonderful man he was, he truly inspired thousands of teachers and students with his method... So he most probably be proud of every one of us for listening to his lectures wondering like little kids and trying to comprehend this awesome and complex universe apparently governed by statistics......😁👌
Feynman is without peer. A phenomenal mind matched with an antic and generous spirit. Dead at 70. What a tremendous loss. I am so incredibly grateful for what he did when he lived.
THE ULTIMATE AND CLEAR MATHEMATICAL PROOF OF THE FACT THAT E=MC2 IS F=MA: Ultimately and truly, TIME is NECESSARILY possible/potential AND actual IN BALANCE; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE. SO, time DILATION ULTIMATELY proves ON BALANCE that E=mc2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. The stars AND PLANETS are POINTS in the night sky. A PHOTON may be placed at the center of THE SUN (as A POINT, of course), AS the reduction of SPACE is offset by (or BALANCED with) the SPEED OF LIGHT; AS ELECTROMAGNETISM/ENERGY IS GRAVITY; AS E=mc2 IS F=ma. Great !!! "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. E=MC2 IS F=MA. Consider the man who IS standing on what is the EARTH/ground. Touch AND feeling BLEND, as ELECTROMAGNETISM/energy is gravity; as E=mc2 IS F=ma. GREAT !!! E=mc2 IS F=ma. The linked AND BALANCED opposite of what is THE SUN is A POINT in the night sky. The stars AND PLANETS are POINTS in the night sky. A PHOTON may be placed at the center of THE SUN (as A POINT, of course), AS the reduction of SPACE is offset by (or BALANCED with) the SPEED OF LIGHT; AS ELECTROMAGNETISM/ENERGY IS GRAVITY; AS E=mc2 IS F=ma. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE. Therefore, the linked AND BALANCED opposite of what is THE EARTH is ALSO A POINT in the night sky. Great. Gravity IS ELECTROMAGNETISM/energy. ELECTROMAGNETISM/ENERGY IS GRAVITY. E=mc2 IS F=ma. Gravity AND ELECTROMAGNETISM/ENERGY are linked AND BALANCED opposites, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Accordingly, the Earth AND the Sun are linked AND BALANCED opposites; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy, AS E=mc2 IS F=ma. The stars AND PLANETS are POINTS in the night sky. It ALL CLEARLY makes perfect sense. Great !!!!!! Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. E=MC2 IS F=MA. The EARTH and the SUN thus constitute and comprise what are the MIDDLE AND THE FULL DISTANCE in/of SPACE (IN BALANCE) in full and BALANCED compliance and conformity with the CLEAR and universal fact that E=mc2 IS F=ma, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Great !!!! It ALL CLEARLY does make perfect sense. (The stars AND PLANETS are POINTS in the night sky.) INDEED, BALANCE and completeness go hand in hand. Now, very importantly, outer "space" involves full inertia; AND it is fully invisible AND black. Great. NOW, OVERLAY what is THE EYE in BALANCED RELATION to/WITH what is THE EARTH. Notice the black space of THE EYE. The stars AND PLANETS are POINTS in the night sky. THE DOME of a person's EYE is ALSO VISIBLE. Now, carefully consider what is the semi-spherical, translucent, QUANTUM GRAVITATIONAL, AND BLUE SKY. Great. E=mc2 IS F=ma. It is CLEAR. THE EARTH is ALSO BLUE (AS WATER). GREAT. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. INSTANTANEITY is thus FUNDAMENTAL to what is the FULL and proper UNDERSTANDING of physics/physical experience, as E=mc2 IS F=ma; as ELECTROMAGNETISM/energy is gravity. Gravity IS ELECTROMAGNETISM/energy. It ALL CLEARLY makes perfect sense. Inertia/INERTIAL RESISTANCE is proportional to (or BALANCED with/as) GRAVITATIONAL force/energy, as this unifies AND balances gravity AND ELECTROMAGNETISM/energy; as this balances gravity AND inertia. (This clearly explains BOTH F=ma AND E=mc2, AS ELECTROMAGNETISM/ENERGY IS GRAVITY !!!) ACCORDINGLY, gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. SO, the BALANCE of being AND EXPERIENCE is essential; AS E=mc2 IS F=ma. Our EXPERIENCE is NECESSARILY that of what is the FULL DISTANCE in/of SPACE, AS we are BALANCED between what are THE SUN AND c (A POINT); AS E=mc2 IS F=ma. The stars AND PLANETS are POINTS in the night sky. SO, a given PLANET (INCLUDING WHAT IS THE EARTH) sweeps out equal areas in equal times; AND this is THEN consistent WITH/as F=ma, E=mc2, AND what is perpetual motion; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. E=mc2 IS F=ma. BALANCE and completeness go hand in hand. It ALL CLEARLY does make perfect sense. THINK about what is QUANTUM GRAVITY. "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent with/as what is BALANCED electromagnetic/gravitational force/ENERGY, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Indeed, gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Therefore, the rotation of WHAT IS THE MOON matches it's revolution !!! Objects fall at the SAME RATE (neglecting air resistance, of course), AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. Gravitational force/ENERGY is proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Stellar clustering ALSO proves ON BALANCE that ELECTROMAGNETISM/energy is gravity, AS E=mc2 IS F=ma. Magnificent !!! E=mc2 IS F=ma. Is a two dimensional surface or SPACE visible or invisible ? The answer is that it is BOTH. So, the electron AND photon are structureless. A PLANET (INCLUDING WHAT IS THE EARTH) is a balanced MIDDLE DISTANCE form in relation to E=mc2 AS F=ma. A PLANET (INCLUDING WHAT IS THE EARTH) is a balanced MIDDLE DISTANCE form in relation to the Sun AND c (A POINT). The stars AND PLANETS are POINTS in the night sky. E=MC2 IS F=MA. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. Gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. BALANCE AND completeness go hand in hand. Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black. E=MC2 IS F=MA. It ALL CLEARLY makes perfect sense. The BALANCE of being AND EXPERIENCE is essential. The INTEGRATED EXTENSIVENESS of THOUGHT (AND description) is improved in the truly superior mind. INSTANTANEITY is thus FUNDAMENTAL to what is the FULL and proper UNDERSTANDING of physics/physical experience. (THOUGHTS ARE INVISIBLE.) It is a very great truth that THE SELF represents, FORMS, and experiences a COMPREHENSIVE approximation of experience in general by combining conscious and unconscious experience. MOREOVER, the ability of THOUGHT to DESCRIBE OR RECONFIGURE sensory experience is ULTIMATELY dependent upon the extent to which THOUGHT IS SIMILAR TO sensory experience. Beautiful. It ALL CLEARLY makes perfect sense. E=mc2 IS F=ma. By Frank Martin DiMeglio
@@saltybits9954 Frank also thinks that energy and electromagnetism IS gravity lol. Gravity isn't a thing, it's a consequence. If E=MC^2 was the same as F=MA then nothing about relativistic movement makes sense. For example, Mercury's orbit no longer makes sense. But Einstein's relativity allowed us to make accurate predictions about Mercury's orbit, something that was not possible before.
80 min lecture and I was left excited about the next one. I studied CED at uni in 84, never understood a thing. I feel confident Prof Feynman is about to change that.
One of the best simplistic historical discussions of QED, that exists on the net. Vast teeming masses of students should be forced to see this. Too bad so few actually get to that level.
I haven't heard many historical discussions about the GED but massive amounts of teens already know about it and shouldn't be forced to take it. It's actually not as hard to achieve as you may think.
@@thomaswayneward You must be at Stanford, MIT, or MSU. 99.9999% of population does not even know that there "IS" a QED vs QCD theory. Then there are GUTS and TOES. These deserve their own exposes on RUclips. Send links to these, if you find some good ones. Bruno.
It is Feynman that put me on the road to my love of science. Not science for its own sake but scientific curiosity. Today people think science is an absolute, which it is, until next week. Feynman once said that whenever everybody (meaning scientists studying the same theory) agreed on a theory they had lost the pursuit of truth.
I just started embarking on the path of science (computer science) a few months ago since I have found a field that sparked my passion. And I have to say science is one of the most beautiful things in the universe. Scientific curiosity is what makes humans so special and what will help us to transcend our biological selves.
This is first time I have seen a lecture of him. I can only say one thing : amazing lecture and such a remarkable person. Truly a genius with both feeth grounded in practicle approach..👍
Feynnman's lectures, and there are many that were recorded, have for me much of the sense of magic tricks. There is a sense of wonder of something new and exotic and if you know what to look for an exhilaration in seeing something is a new way. But I pity the poor student that had not spend several hours pre-reading the chapter. Thank god he taught at Cal Tech. I got to see Hans Bethe at Cornell Arts & Science physics 101B back in the days when I was a Math Major and I would describe him as completely delightful as a guest lecturer.
"Magician" is a good label for him. Spent the past three days digging into his background and confirmed what I already suspected. His cult of genius comes from social acceptance without any criticism. There is a FOIA request available online that contains a 400 page FBI report on Feyman from the 1950s and declassified in 1989.
Theoretical physicist Richard Freyman is outstanding n amazing in his lecture on quantum mechanics. He is also a prominent scientist and contributed his knowleges to help solved critical disaster liked the explosion of the spaceship Apollo. He is also a member of the Manhattan projects with other wellknown scientists like Albert Einstein. The world had lost such an expert and is most regrettable for a long long times. I m always admired his on line leatures snd his humours.
That was apart of what is called the "Feynman Technique" of learning. Basically if you can't explain any complex topic in simple terms you do not understand it well enough.
Fascinating. The arrow rotations are like the generation of sine waves, with the waves interfering, constructively or destructively. So this is a way of doing that with particles rather than waves.
This lecture changed my life many years ago. Allowing me to look at a puddle of oil and water with awe and understanding. Also viewing life choices as Arrows and trying to make the arrows add up to something rather than ultimately canceling out.
The gesture at 32:39: due to the efficiency of the conquistadores, mainly their priests who burned all the Mayan’s books, they had 100,000 books, there are only three left.
It always amazes me how similar the ambiance and delivery of Richard Feynman is to that of the deceased comedian, Art Carney. Even their accents and hair are similar. You really see the similarities "shine through" when Feynman takes audience questions, at the end of the video.
Dick Feynman was not just a genius in physics, and outrageous trickster, and smart and cool. He was also a great teacher, educator, and... entertainer. It's so sad that this video is not forced on physics students all over the world as a pre-condition to studying Quantum mechanics. I Have a suspicion that physics professors still like their hold as "explainers" of reality, and not as mere, confused "describers" of reality. But maybe I'm wrong.
Was suggested to go through the Feynman Lectures, the Berkley Lectures, the Hartley Lectures, to know better about Physics , may be 50 yrs back [ these were printed ones then, not easily in our reach], in a semi-urban college in India where I studied. Never learnt Physics or science or anything that well, and lifetime spent in some nondescript commercial office job. However at this retired and inactive life phase, this came up on cellphone. It is nice !
2022-03-20: It’s going to take more than once through this. But the probability of me understanding increases with each opportunity to listen. And that’s okay. I love listening to Feynman. His accent and delivery make me think of Jackie Mason and Irwin Corey. A photon walks into a bar has a couple drinks and gets up to leave. Bartender says, “Did you have a coat?” Photon says, “No, I’m traveling light.”
In another life, Feynman will make a world class stand up comedian. Light works by probability. With that statement, he has given so much to the knowledge of how we see and then understand (or not) our surroundings and 'understanding' of them.
@@justincase4812 Even he didn't say he was right, only that this explanation and its calculations work better than any others, and to the accuracy with which we can currently (1990 and 2023?) measure.
Ah! What a great impact a great teacher can have. I have had over six years of college, including an Ivy League masters, and yet to think back to brilliant teachers and ones who had a lasting impact, I must think back to High School! I was fortunate to attend a very good high school, took AP classes, and decades later I still think back to the excitement and love of learning imparted by a number of those superb teachers, courses ranging from physics, to literature, to art, and mathematics. I did like some teachers in undergrad college, but they did not rise to the level I described. And as for Ivy League masters professors??? Hahaha, they were rather comically poor teachers, and as a group quite dull, untalented and uninspiring. The best were renowned "guest" teachers, not the professors. At least we have the stellar Feynman here on RUclips!!!
@@schmetterling4477 Nothing of the sort. I simply made a comment like millions and millions of other people do. I haven't the foggiest idea why you focused in on my comment. My main point was to praise my excellent high school teachers, and to point out the possible irony of the fact that the skill of teachers does not necessarily increase as one goes up the educational ladder.
I’ve got his quantum physics audiobooks, in 20 volumes but no video, which is a shame as I’m pretty sure I would understand much more had I actually seen what he was going on about but there’s enough to kind of get the gist and they are phenomenal - this video is just amazing, what a fantastic mind xxx
Always loved his bemused quizzical attitude toward all things in general. Picture him on the Sistine Ceiling reaching a finger out to impart the spark of life to God.
There is a very high probability that at some point you will be a teacher. Perhaps as a parent teaching your children. Perhaps just helping a friend with a problem that you can solve. Please remember this lecture and what a wonderful example it is, that great teachers are entertainers who capture the interest and attention of their students and present information in a way their students enjoy and understand.
Definitely one of the greatest scientific minds we've ever known. So charismatic too! I was way too young to meet him while he was alive, but I wish I would have had the chance.
@@schmetterling4477 I genuinely don't know what you mean by that unless you're referencing the fact that he said that he won't really die as he's told so many stories that he'll still be remembered.
I love the simple logic this great man used to tell NASA why their Challenger blew up. A O ring got stiff because the cold temperatures before launch. Then he illustrates this with some ice water and a piece of O ring. Pure common sense.
G'day, Kristen Sorensen! Yes, I remember first listening to the book being read on radio back in 1980's ("Surely You're Joking, Mr. Feynman") and some years after that, actually reading the book in print. He bought some rubber O rings and placed one into a glass of ice water provided at the committee sessions when the Challenger disaster was being investigated. Great read! There is also an amusing and interesting section on the difficulty in learning the Japanese language, which Feynman tried for a while.
In other words, if you had more teachers with more information about the universe, you would have more information about the universe. Yes. I certainly agree.
Basically, near the end of this video lecture segment, Feynman is describing a probability mathematics which seems largely borrowed from the *phasor math* invented by Charles Proteus Steinmetz. Steinmetz invented his branch of applied math to describe the RLC dynamics of AC electrical circuits. To learn more about Steinmetz, look up the _Kathy Loves Physics_ RUclips channel.
After listening to Mr. Feynman I find him aghast that there might be a God, a designer. I could be wrong about my judgment but even as a Christian I find him to be delightful to listen to. I just got back from an International Creation Conference where 48 Phds spoke about their understanding that we have a young Earth. I would have loved to met and spent time with this man.
Respect to Feynman as one of the greatest thinkers and speakers in science. I'm sure he would be amused by the confusion and ambiguity caused by dumbing down numbers as at 3:17 - 400 nm would nail it! And they're still doing it with their billion trillions and thousand million trillionths. The fact that we're interested in science at all means we're capable of understanding scientifically expressed numbers, or finding out how.
@@brentfodera377 Well yes I think it may be done for effect BUT didn't he rather shoot himself in the foot since 4 100,000,000ths of a cm = 0.4nm and 400 1,000,000ths of a cm = 4,000nm ! Both wrong! He should have said "Four hundred (slight pause) millionths of a millimetre" . Sorry but genius though he was, he made a mistake here and my point about the pitfalls of dumbing down stands. My admiration for Feynman is not diminished but he needed posthumously calling out on this!
I always thought of it this way: Biologist sweats when she learns biology is just chemistry at a large scale...... Chemist sweats when he learns chemistry is just the physics of atoms and their electrons...... Physicists sweat when they learn physics is the application of mathematics to matter...... Mathematicians explain their theories to us and we can't understand a thing because we're biological creatures......
To this day, still the most honest and non biased explanation of QM. Feynman never gives his interpretation of the rules. Today we have the "many worlds" people fetishising the wave function even though no one has ever seen the wave function in nature and all that is ever detected is "particles". Of course the wave function is important as a mathematical device to make predictions but is it in any way Physical?? I think it comes down to the old philosophical disagreement about the status of mathematics. Is it a human construct or a somehow a fundamental part of the universe . If you believe in evolution then i don't understand how you can elevate human potential understanding much further than any other ape. In this respect , physicists hold a religious view of the ability of mankind to understand the cosmos that they do not grant to any other species. Mabye we just need to accept that like chimps do not have the cognitive structures to understand language, humans lack the cognitive structures to understand QM
How fortunate these audience are. I mean..... This is the man who was part of the Manhattan project. This man has rubbed shoulders with Oppenheimer, Bohr, Dirac. Woooow
It's funny how folks at these lectures can't seem to come up with good questions. Here are some questions I would have liked to ask him. Granted, people in the audience may not have the ability to ask detailed questions, but still.... "When you see something, is it the light from the object that you see, or is it the object that you see?" Come on. Clearly the object is actually jumping into your eyeball. Anyway, if anyone knows the answers, feel free to answer, please. Regarding the interaction of reflections from 2 different surfaces: Suppose your 2 surfaces are a very large distance apart - say, one light-second apart, but still positioned just right so your photons destructively interfere. Should you expect to get a reflection for 2 seconds - the time it would take for photons returning from the far surface to return and interfere with the photons from the first surface? The way Feynman describes it, you should get no reflection at all, and there would have to be some instantaneous information transmission. If whether or not the photons constructively or destructively interfere is actually due to an aggregation of reflections throughout the substance, and not actually due to the existence of the "surfaces," which are actually a sort of fiction, then why can't you ever get destructive interference of photons if the detector is below the first "surface?" I.e., inside the substance (and, as in the case of the detector outside the substance, if photons are only allowed to approach the detector from below). Also, when your detector is inside the substance, why are no photons detected coming from anywhere but the bottom "surface?" Maybe destructive interference is responsible for this, but not at all as explained as in the case of the detector outside, and certainly not dependent on the detector's distance from the bottom "surface." If photons are individual particles, what is the duration of a photon? To illustrate what I mean, consider an extremely low frequency photon - a photon having a wavelength of, for example, one light-minute. Now, supposing you can control the time and direction at which the photon is emitted, you send this photon through an aperture which you are capable of dilating and contracting. At the time at which the photon reaches the aperture, the aperture is large enough to admit the photon. Before one minute has elapsed, suppose, at 30 seconds, the aperture is contracted to a size that the photon cannot move through. Does the photon get through? Is the photon detectable only between the aperture and 30 light seconds beyond it? How quickly can you close the aperture and still allow the photon to pass if the answer is not one minute? Or, does the photon have no transverse length, and always pass, provided the aperture is of a size that would permit the photon to pass at the moment when the photon reaches it? And if this is the case, then how is the information of wavelength carried by the photon? There is a good PSSC video about the experiment that demonstrates that light is made up of particles (which Feynman references) done by John King that illustrates the principles of that experiment very well, but the aperture size and duration in that experiment was nowhere near the scale of the wavelength and frequency of the light investigated. I suspect that the answer is that 100% of the photons get through when it takes 1 minute to close, 50% get through when it takes 30 seconds and so on, because, I suspect, the order of the size of the aperture at which 100% of the photons pass is 1 light-minute in diameter, which limits how quickly you can close the aperture sufficiently, which is maddeningly unsatisfying. Well thanks to anyone who read this far. I think that's enough questions for one post.
AI should be used to improve picture quality and sound on this. It is a beautiful recording of a wonderful man, and everything he says is still valid today.
Alan Watts! 'A disreputable epicurean.' That was his own rather generous description of himself. More a disreputable charlatan, alcoholic philanderer who couldn't embody any of the nonsense that he purported to be true.
Imagine Joe Pesci playing Feynman. So, what do YOU think makes light travel at that high speed? What is the length of time that it takes after a particle of light is created for it to get up to light speed? If light travels in a wave form, what properties does it have that make it return and cross over the x axis continuously instead of travel in a straight line? What is the force? What makes Gamma rays able to escape black holes?
Today, we experimentally know that this gyro-magnetic ratio for muons depends on the mass of the parent quarks decaying I to stable quarks and muons, the phenomenon called muon g-2 anomaly.
I'd rather learn from someone who teaches what he knows, and acknowledges when he doesn't. Than to learn from someone who teaches what he thinks he knows, because then that will only be an idea.

Is there video of the conference of chapel hill with Fehnman debating unified field theory? I appreciate that Fehnman could bring such abstract and profound theories to everyman's "understanding."
Until you read his undergrad textbooks and you are astonished how such a congenial physicist could make so many obvious mistakes. And then it strikes you... he didn't care about teaching.
Readers who like Physics. Can you understand this post on the concept of Dimp, the dimensionlesspoint, I am struggling to explain it clearly. This from the next Musea. 1. DIMP stands for dimensionless point - DIM-ensionless P-oint . This is a single point outside the universe, that contains all light! This is a challenging concept and difficult to even imagine. How can anything, let alone all that, be in a point without dimensions? But it's based on what we know now. When you understand my single concept of DIMP, the rest of these physics ideas fall into place. So I will try to explain it in a couple of ways. Read, this section carefully! Dimp or the dimensionless point is a single point that contains all PHOTONS. (For visual purposes, think of photons as little pieces of light.) That means Dimp contains all ELECTROMAGNETIC ENERGY in a single dimensionless point. That means all light is in a single point, a point that doesn't have four dimensions, or three, or two, or even one! Pauli's Exclusion Principle is a clue. It says all photons ( a type of boson), can be in one point while their counterpart, fermions, cannot. Remember a PHOTON DOES NOT OCCUPY SPACE! There is no limit to how many can occupy the same quantum state. Photons, all of them, can be in a single point! By definition we know that photons are outside of time and distance. Infinite time dilation (no time) goes hand in hand with infinite length contraction (no distance to the destination). Because a photon is outside time, it is eternal. Because a photon is outside distance, there is no distance between any two photons. They are all together in an eternal point. They share a dimensionless point! That means all light is in one point. If there is no distance than photons are everywhere at once - or everywhere at once and back! That means that the photons in the singularity that started the big bang and our entire universe, are here now today, and will be here forever in the future. Here's an official quote from Physics org: From the perspective of a photon, there is no such thing as time... It doesn't experience distance either. My idea that all light energy is gathered in Dimp, a single dimensionless point, eternal and outside of space-time, is not easy to comprehend. Let's try this visual analogy. Look at photons, not as individual particles or waves of light, but as a quantum ENERGY FIELD that is everywhere at once, a BLANKET OF LIGHT that surrounds everything in the universe and is in every part of space time at the same time. Still with me? Because Dimp is eternal and outside time; that means Dimp is these things: 1. Here before the Big Bang, during the Big Bang, and here long after this universe will have ended. A vast reservoir of all energy. And our universe, where there is space and time, is a small subset of Dimp, just as an ember is a small subset of a massive bonfire. Dimp was the singularity, the dimensionless point, that the Big Bang exploded out of. That means Dimp is separate from, not only time and distance, but gravity, mass, space, you name it! There is no acceleration in DIMP therefore no gravity!. There is no expansion in DIMP and no charge. Further the virtually endless amount of energy in Dimp never changes. That is some weird point! Dimp, the dimensionless point concept seems to explain all the following separate concepts; COSMOLOGICAL CONSTANT, ZERO POINT ENERGY, VIRTUAL PARTICLES, ENTANGLEMENT OR 'SPOOKY ACTION AT A DISTANCE', AND VACUUM ENERGY. Dimp also means the electromagnetic force and force of gravity (see later) are not connected. They are separate and can't be unified. The simplest way to explain Dimp is to start by saying, there are TWO UNIVERSES. THE FIRST UNIVERSE is DIMP, the dimensionless point, or the universe of photons, light, and energy, where everything that is, goes the "speed of light". THE SECOND UNIVERSE is SPACE - TIME where everything goes slower than the speed of light. This is the universe of everything that is - BUT photons. Nothing in Dimp goes slower than the speed of light. Nothing in the universe goes the speed of light. Does that help clarify? BUT WAIT, it gets more strange... The problem is that to have a "speed of light" one has to have both time and distance. But a photon from it's point of view is outside of both time and distance. From our space-time point of view it looks like photons are going a set distance in a set time, but that is our illusion, not their fact. So "speed of light" is a misnomer. More about this puzzle later. . Physics often uncovers a dark zone of unexplained phenomenon. Dimp may help explain those dark zones including: 1. The singularity where the big bang began. 2. Dimp, the dimensionless point of all photons, all light. 3. The dark area in an atom during a quantum jump where the electron instantly jumps over, when it jumps from shell to shell. " Everything in the quantum mechanical universe ... happens in quantum leaps. A quantum leap is a discontinuous transit between quantum states - an electron jumps instantly into another energy level... There is no in between state and it doesn't take anytime for the leap to occur." Moring. 4. The empty zone in an atom where the electron orbital is not. 5. The Two Slit Experiment black bands where no particles/waves land. 6. The nodes of waves where the particle probability is zero. 7. When two mirror image waves collide, constructive interference occurs which annihilates both waves, and turns them into pure energy. Dimp is that pure energy. 8. Virtual Particles where particle A and Particle B pop up out of the void, then come together and there is total annihilation. 9. Quantum tunneling? The space between when Particle A disappears on one side and materializes on the other side. 10. Entangled particles where A and B are strangely and instantly connected no matter the distance between them. 11. Force carriers. 12. the infinities that renormalization tries to fix. With Dimp they are correct as is. 13. Wheeler's Great Smoky Dragon analogy, where A is the head of the dragon, B is the tail of the dragon and the area between is smoke. 14. The 120 orders of magnitude of the vacuum energy density or cosmological constant. 15. Non locality may also be explained by Dimp which is outside of time and space. Where is Dimp? Everywhere that there is vacuum energy or space, or everywhere!That's because any surface not at absolute zero emits photons, and absolute zero can't be reached. It"s both outside and inside space time! But wait - more weirdness: PHOTONS DON'T GO ANYWHERE. Remember the speed of light problem? Photons do not move out of dimp! If they did they would have time and distance, which they do not! Photons pop out of Dimp. They are created out of Dimp and return to Dimp. Text books say, the only interactions a photon has, are to be created or destroyed. We see a photon being created or destroyed, but nothing in between! Through pair conversion they send MESSENGERS: Electron / Positron pairs as the energy to do the work . That suggests that electrons and positrons are vehicles for photon energy! That means when a photon pops up in our universe, it does so only as an electron / positron pair! We know that as an object approaches the speed of light it: becomes heavier and approaches infinite mass, (Infinite mass is also infinite energy, E=MC2). It contracts in length, and time slows. Could that object keep going faster, it would reach the speed of light and be outside of time and be eternal. SO if mass could go the speed of light (and it can only approach it) it would be infinite energy with no length in a single dimensionless point, outside of time! Sound familiar? That is DIMP! Totally confused? Take a break and try this visual exercise: The light from all stars shine out in every direction with eternal photons that are everywhere all at once. Look, a web of photons connect all space and all time, now and forever - a net of light!
"dim light less per second" at 40:38 is self-contradictory because less per second is an analog wave. A digital particle stream would be dim light fewer per second.
The really unfortunate thing is that the particle thing is not true to begin with. "Light" does not have any photons. Only the interaction of light with matter creates photons. Which is even harder to understand for the layman because what holds matter together is... light. ;-)
Checking in 2024. A privilege to get to watch Feynman on YT!

Here I am, an MBA student at Lehigh University specializing in data analytics, more than captivated at a lecture over 40 years old: a lecture that is so much better than any I’ve had, ever. What an incredible teacher.
How does it feel to know all the Einstein crap you learned is wrong?
Best of luck with your MBA.
@@saltybits9954crap? Such as?
Yes, calling Einstein crap is a bit strong. His only major error was his “cosmological constant”, of which he termed his ‘greatest blunder’
There’s a strong temptation for people to welcome every claim that all historical discoveries are mistakes but if the maths holds with observations, we should accept theories that stand testing as with Einstein
@@DavidMcMillan888 That is not true. You can find a much more serious mistake in his photoelectric effect paper. It's just not well known, but it is very easy to spot.

@@radiotelegram They will. Like Einstein useful idiots.
I have never heard a better teacher: one of the most brilliant minds ever, but perhaps his true incandescence was his ability to comprehend the layman's mind and make this bizarre world accessible to many.
He was a teacher of teachers. Esteemed university professors used to drop what they were doing and gatecrash his lectures, listening to the Master as if they were hearing concepts for the first time.
His true beauty was that he HAD a layman's mind, just one that worked to see more clearly, and one that would accept everything exactly as it was, not as he wished or assumed it to be.
You had really bad teachers then
@@saltybits9954 Why do you think he is a bad teacher? You have trouble following his arguments?
@@oogba71 I didnt say he was a bad teacher. Just a useful idiot. Thats what Tesla said about Einstein and all his ilk. I trust Tesla. He's right about everything. Einstein was an establishment pawn just like Feynman. Both idiots. Both wrong. Both guilty of crimes against humanity for lies and deception of the highest order.
One true sign of genius is the ability to take an enormously difficult topic, like quantum physics, and simplify it to such a degree that most people, who are not scientists, can begin to understand it. Yes, teaching is just as important as discovery. Professor Feynman rips apart the false adage 'if you can't do, teach.' Of what use is to have the gift of discovering great ideas if you don't have the gift of communicating those ideas to others? Professor Feynman had both of these extremely rare gifts. Truly a giant.

THE ULTIMATE AND CLEAR MATHEMATICAL PROOF OF THE FACT THAT E=MC2 IS F=MA:
Ultimately and truly, TIME is NECESSARILY possible/potential AND actual IN BALANCE; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE. SO, time DILATION ULTIMATELY proves ON BALANCE that E=mc2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. The stars AND PLANETS are POINTS in the night sky. A PHOTON may be placed at the center of THE SUN (as A POINT, of course), AS the reduction of SPACE is offset by (or BALANCED with) the SPEED OF LIGHT; AS ELECTROMAGNETISM/ENERGY IS GRAVITY; AS E=mc2 IS F=ma. Great !!! "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. E=MC2 IS F=MA.
Consider the man who IS standing on what is the EARTH/ground. Touch AND feeling BLEND, as ELECTROMAGNETISM/energy is gravity; as E=mc2 IS F=ma. GREAT !!!
E=mc2 IS F=ma. The linked AND BALANCED opposite of what is THE SUN is A POINT in the night sky. The stars AND PLANETS are POINTS in the night sky. A PHOTON may be placed at the center of THE SUN (as A POINT, of course), AS the reduction of SPACE is offset by (or BALANCED with) the SPEED OF LIGHT; AS ELECTROMAGNETISM/ENERGY IS GRAVITY; AS E=mc2 IS F=ma. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE. Therefore, the linked AND BALANCED opposite of what is THE EARTH is ALSO A POINT in the night sky. Great. Gravity IS ELECTROMAGNETISM/energy. ELECTROMAGNETISM/ENERGY IS GRAVITY. E=mc2 IS F=ma.
Gravity AND ELECTROMAGNETISM/ENERGY are linked AND BALANCED opposites, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Accordingly, the Earth AND the Sun are linked AND BALANCED opposites; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy, AS E=mc2 IS F=ma. The stars AND PLANETS are POINTS in the night sky. It ALL CLEARLY makes perfect sense. Great !!!!!! Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. E=MC2 IS F=MA.
The EARTH and the SUN thus constitute and comprise what are the MIDDLE AND THE FULL DISTANCE in/of SPACE (IN BALANCE) in full and BALANCED compliance and conformity with the CLEAR and universal fact that E=mc2 IS F=ma, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Great !!!! It ALL CLEARLY does make perfect sense. (The stars AND PLANETS are POINTS in the night sky.) INDEED, BALANCE and completeness go hand in hand. Now, very importantly, outer "space" involves full inertia; AND it is fully invisible AND black. Great.
NOW, OVERLAY what is THE EYE in BALANCED RELATION to/WITH what is THE EARTH. Notice the black space of THE EYE. The stars AND PLANETS are POINTS in the night sky. THE DOME of a person's EYE is ALSO VISIBLE. Now, carefully consider what is the semi-spherical, translucent, QUANTUM GRAVITATIONAL, AND BLUE SKY. Great. E=mc2 IS F=ma. It is CLEAR. THE EARTH is ALSO BLUE (AS WATER). GREAT. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy.
INSTANTANEITY is thus FUNDAMENTAL to what is the FULL and proper UNDERSTANDING of physics/physical experience, as E=mc2 IS F=ma; as ELECTROMAGNETISM/energy is gravity. Gravity IS ELECTROMAGNETISM/energy. It ALL CLEARLY makes perfect sense. Inertia/INERTIAL RESISTANCE is proportional to (or BALANCED with/as) GRAVITATIONAL force/energy, as this unifies AND balances gravity AND ELECTROMAGNETISM/energy; as this balances gravity AND inertia. (This clearly explains BOTH F=ma AND E=mc2, AS ELECTROMAGNETISM/ENERGY IS GRAVITY !!!) ACCORDINGLY, gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. SO, the BALANCE of being AND EXPERIENCE is essential; AS E=mc2 IS F=ma.
Our EXPERIENCE is NECESSARILY that of what is the FULL DISTANCE in/of SPACE, AS we are BALANCED between what are THE SUN AND c (A POINT); AS E=mc2 IS F=ma. The stars AND PLANETS are POINTS in the night sky. SO, a given PLANET (INCLUDING WHAT IS THE EARTH) sweeps out equal areas in equal times; AND this is THEN consistent WITH/as F=ma, E=mc2, AND what is perpetual motion; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. E=mc2 IS F=ma. BALANCE and completeness go hand in hand. It ALL CLEARLY does make perfect sense. THINK about what is QUANTUM GRAVITY.
"Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent with/as what is BALANCED electromagnetic/gravitational force/ENERGY, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Indeed, gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Therefore, the rotation of WHAT IS THE MOON matches it's revolution !!! Objects fall at the SAME RATE (neglecting air resistance, of course), AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. Gravitational force/ENERGY is proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY.
Stellar clustering ALSO proves ON BALANCE that ELECTROMAGNETISM/energy is gravity, AS E=mc2 IS F=ma. Magnificent !!!
E=mc2 IS F=ma. Is a two dimensional surface or SPACE visible or invisible ? The answer is that it is BOTH. So, the electron AND photon are structureless. A PLANET (INCLUDING WHAT IS THE EARTH) is a balanced MIDDLE DISTANCE form in relation to E=mc2 AS F=ma. A PLANET (INCLUDING WHAT IS THE EARTH) is a balanced MIDDLE DISTANCE form in relation to the Sun AND c (A POINT). The stars AND PLANETS are POINTS in the night sky. E=MC2 IS F=MA. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. Gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. BALANCE AND completeness go hand in hand. Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black. E=MC2 IS F=MA. It ALL CLEARLY makes perfect sense.
The BALANCE of being AND EXPERIENCE is essential. The INTEGRATED EXTENSIVENESS of THOUGHT (AND description) is improved in the truly superior mind. INSTANTANEITY is thus FUNDAMENTAL to what is the FULL and proper UNDERSTANDING of physics/physical experience. (THOUGHTS ARE INVISIBLE.) It is a very great truth that THE SELF represents, FORMS, and experiences a COMPREHENSIVE approximation of experience in general by combining conscious and unconscious experience. MOREOVER, the ability of THOUGHT to DESCRIBE OR RECONFIGURE sensory experience is ULTIMATELY dependent upon the extent to which THOUGHT IS SIMILAR TO sensory experience. Beautiful. It ALL CLEARLY makes perfect sense. E=mc2 IS F=ma.

@@frankdimeglio8216 It has been proven that light is NOT a constant. Therefore E=MC² is false. Just like Tesla said. Einstein useful idiots.
@@saltybits9954 Frank also thinks that energy and electromagnetism IS gravity lol. Gravity isn't a thing, it's a consequence. If E=MC^2 was the same as F=MA then nothing about relativistic movement makes sense. For example, Mercury's orbit no longer makes sense. But Einstein's relativity allowed us to make accurate predictions about Mercury's orbit, something that was not possible before.

80 min lecture and I was left excited about the next one. I studied CED at uni in 84, never understood a thing. I feel confident Prof Feynman is about to change that.
One of the best simplistic historical discussions of QED, that exists on the net. Vast teeming masses of students should be forced to see this. Too bad so few actually get to that level.
I haven't heard many historical discussions about the GED but massive amounts of teens already know about it and shouldn't be forced to take it. It's actually not as hard to achieve as you may think.
There is no "level", any one can view this and get much from it.
@@thomaswayneward You must be at Stanford, MIT, or MSU. 99.9999% of population does not even know that there "IS" a QED vs QCD theory. Then there are GUTS and TOES. These deserve their own exposes on RUclips. Send links to these, if you find some good ones. Bruno.
It is Feynman that put me on the road to my love of science. Not science for its own sake but scientific curiosity. Today people think science is an absolute, which it is, until next week. Feynman once said that whenever everybody (meaning scientists studying the same theory) agreed on a theory they had lost the pursuit of truth.
Too much puffed upness in todays "scientists".
I just started embarking on the path of science (computer science) a few months ago since I have found a field that sparked my passion. And I have to say science is one of the most beautiful things in the universe. Scientific curiosity is what makes humans so special and what will help us to transcend our biological selves.
This is first time I have seen a lecture of him. I can only say one thing : amazing lecture and such a remarkable person. Truly a genius with both feeth grounded in practicle approach..👍
Yes. I was too young to hear him live. So I am grateful that someone had the foresight to record and place online.

Feynnman's lectures, and there are many that were recorded, have for me much of the sense of magic tricks. There is a sense of wonder of something new and exotic and if you know what to look for an exhilaration in seeing something is a new way.
But I pity the poor student that had not spend several hours pre-reading the chapter. Thank god he taught at Cal Tech.
I got to see Hans Bethe at Cornell Arts & Science physics 101B back in the days when I was a Math Major and I would describe him as completely delightful as a guest lecturer.

@@LouAlvis - Use the RUclips 'Search box'.
"Magician" is a good label for him. Spent the past three days digging into his background and confirmed what I already suspected. His cult of genius comes from social acceptance without any criticism. There is a FOIA request available online that contains a 400 page FBI report on Feyman from the 1950s and declassified in 1989.
Theoretical physicist Richard Freyman is outstanding n amazing in his lecture on quantum mechanics. He is also a prominent scientist and contributed his knowleges to help solved critical disaster liked the explosion of the spaceship Apollo. He is also a member of the Manhattan projects with other wellknown scientists like Albert Einstein. The world had lost such an expert and is most regrettable for a long long times. I m always admired his on line leatures snd his humours.
That was a lot of fake news, kid. ;-)
I have only a HS education, yet he made everything in the lecture entirely intelligible to me. That is genius.
That was apart of what is called the "Feynman Technique" of learning. Basically if you can't explain any complex topic in simple terms you do not understand it well enough.
This guy is such a genius.... I will need to listen to this lecture at least three times. ..... and then, I might understand part the information.

Great teacher. Phenomenal mind.
It always amazes me how similar the ambiance and delivery of Richard Feynman is to that of the deceased comedian, Art Carney. Even their accents and hair are similar. You really see the similarities "shine through" when Feynman takes audience questions, at the end of the video.
Dick Feynman was not just a genius in physics, and outrageous trickster, and smart and cool. He was also a great teacher, educator, and... entertainer. It's so sad that this video is not forced on physics students all over the world as a pre-condition to studying Quantum mechanics. I Have a suspicion that physics professors still like their hold as "explainers" of reality, and not as mere, confused "describers" of reality. But maybe I'm wrong.
I thought is was great that I finally found out what the math, I couldn't understand, was trying to say!
He was also a sex maniac. How do I know that fact? From his own autobiography.
He kept my attention, which is difficult for any teacher...
All who can get youtube can find this :)
Was suggested to go through the Feynman Lectures, the Berkley Lectures, the Hartley Lectures, to know better about Physics , may be 50 yrs back [ these were printed ones then, not easily in our reach], in a semi-urban college in India where I studied.

I have had over six years of college, including an Ivy League masters, and yet to think back to brilliant teachers and ones who had a lasting impact, I must think back to High School! I was fortunate to attend a very good high school, took AP classes, and decades later I still think back to the excitement and love of learning imparted by a number of those superb teachers, courses ranging from physics, to literature, to art, and mathematics. I did like some teachers in undergrad college, but they did not rise to the level I described. And as for Ivy League masters professors??? Hahaha, they were rather comically poor teachers, and as a group quite dull, untalented and uninspiring. The best were renowned "guest" teachers, not the professors.

And you have NOTHING of value or truth.
Always loved his bemused quizzical attitude toward all things in general. Picture him on the Sistine Ceiling reaching a finger out to impart the spark of life to God.
Some people read physics. But here physics reads the man. Always a great lecture from him.
There is a very high probability that at some point you will be a teacher. Perhaps as a parent teaching your children. Perhaps just helping a friend with a problem that you can solve. Please remember this lecture and what a wonderful example it is, that great teachers are entertainers who capture the interest and attention of their students and present information in a way their students enjoy and understand.

I love the simple logic this great man used to tell NASA why their Challenger blew up. A O ring got stiff because the cold temperatures before launch. Then he illustrates this with some ice water and a piece of O ring. Pure common sense.
Feynman was part of a committee that made the findings.
G'day, Kristen Sorensen! Yes, I remember first listening to the book being read on radio back in 1980's ("Surely You're Joking, Mr. Feynman") and some years after that, actually reading the book in print. He bought some rubber O rings and placed one into a glass of ice water provided at the committee sessions when the Challenger disaster was being investigated. Great read! There is also an amusing and interesting section on the difficulty in learning the Japanese language, which Feynman tried for a while.
If I had a teacher like him for every subject I took since 1st grade , I would have had more information about the universe
You do, now!
Understatement
If you had had teachers like Feynman you wouldn't believe in superstitions (child of god??)
Raphael? Seriously I like harsh truth ☺️
In other words, if you had more teachers with more information about the universe, you would have more information about the universe. Yes. I certainly agree.
As a student of class 12th its good to see this video ❤
Basically, near the end of this video lecture segment, Feynman is describing a probability mathematics which seems largely borrowed from the *phasor math* invented by Charles Proteus Steinmetz. Steinmetz invented his branch of applied math to describe the RLC dynamics of AC electrical circuits. To learn more about Steinmetz, look up the _Kathy Loves Physics_ RUclips channel.
What a joy listening to this force of nature.
I so glad the audio is good. The picture seems fuzzy, def not 4k, but hearing the lecture is great!
Thank you very much. The lesson was very clear and easily understood.
The Clint Eastwood of physics! Interesting to listen to.
After listening to Mr. Feynman I find him aghast that there might be a God, a designer. I could be wrong about my judgment but even as a Christian I find him to be delightful to listen to. I just got back from an International Creation Conference where 48 Phds spoke about their understanding that we have a young Earth. I would have loved to met and spent time with this man.
Why are you telling us that you didn't pay attention in school? We don't care. ;-)
What goes around comes around a good quote from the master of mathematics.
even with such difficult food for thought, his humor always there 4:02 😁
Respect to Feynman as one of the greatest thinkers and speakers in science. I'm sure he would be amused by the confusion and ambiguity caused by dumbing down numbers as at 3:17 - 400 nm would nail it! And they're still doing it with their billion trillions and thousand million trillionths. The fact that we're interested in science at all means we're capable of understanding scientifically expressed numbers, or finding out how.
I think he was saying that fir effect. The prefix nano was adopted by scientists in 1947, so the word nanometer was certainly available in 1979.
@@brentfodera377 Well yes I think it may be done for effect BUT didn't he rather shoot himself in the foot since 4 100,000,000ths of a cm = 0.4nm and 400 1,000,000ths of a cm = 4,000nm ! Both wrong! He should have said "Four hundred (slight pause) millionths of a millimetre" . Sorry but genius though he was, he made a mistake here and my point about the pitfalls of dumbing down stands.
My admiration for Feynman is not diminished but he needed posthumously calling out on this!
Feynman: "The way how atoms combine in chemistry is in fact theoretical physics..."
Chemists: sweats in anxiety
Lol
It's not a joke!
No, chemists understand that.
I always thought of it this way:
Biologist sweats when she learns biology is just chemistry at a large scale......
Chemist sweats when he learns chemistry is just the physics of atoms and their electrons......
Physicists sweat when they learn physics is the application of mathematics to matter......
Mathematicians explain their theories to us and we can't understand a thing because we're biological creatures......
@@sabatino1977 This is so true, it's funny😂
To this day, still the most honest and non biased explanation of QM. Feynman never gives his interpretation of the rules. Today we have the "many worlds" people fetishising the wave function even though no one has ever seen the wave function in nature and all that is ever detected is "particles". Of course the wave function is important as a mathematical device to make predictions but is it in any way Physical??
I think it comes down to the old philosophical disagreement about the status of mathematics. Is it a human construct or a somehow a fundamental part of the universe .
If you believe in evolution then i don't understand how you can elevate human potential understanding much further than any other ape. In this respect , physicists hold a religious view of the ability of mankind to understand the cosmos that they do not grant to any other species. Mabye we just need to accept that like chimps do not have the cognitive structures to understand language, humans lack the cognitive structures to understand QM
You are clearly too much on the internet and not enough in the library. ;-)
How fortunate these audience are. I mean..... This is the man who was part of the Manhattan project. This man has rubbed shoulders with Oppenheimer, Bohr, Dirac. Woooow
It's not clear just how much he contributed, though. He himself is playing it down, if anything.
It's funny how folks at these lectures can't seem to come up with good questions. Here are some questions I would have liked to ask him. Granted, people in the audience may not have the ability to ask detailed questions, but still.... "When you see something, is it the light from the object that you see, or is it the object that you see?" Come on. Clearly the object is actually jumping into your eyeball. Anyway, if anyone knows the answers, feel free to answer, please.
Regarding the interaction of reflections from 2 different surfaces: Suppose your 2 surfaces are a very large distance apart - say, one light-second apart, but still positioned just right so your photons destructively interfere. Should you expect to get a reflection for 2 seconds - the time it would take for photons returning from the far surface to return and interfere with the photons from the first surface? The way Feynman describes it, you should get no reflection at all, and there would have to be some instantaneous information transmission.
If whether or not the photons constructively or destructively interfere is actually due to an aggregation of reflections throughout the substance, and not actually due to the existence of the "surfaces," which are actually a sort of fiction, then why can't you ever get destructive interference of photons if the detector is below the first "surface?" I.e., inside the substance (and, as in the case of the detector outside the substance, if photons are only allowed to approach the detector from below). Also, when your detector is inside the substance, why are no photons detected coming from anywhere but the bottom "surface?" Maybe destructive interference is responsible for this, but not at all as explained as in the case of the detector outside, and certainly not dependent on the detector's distance from the bottom "surface."
If photons are individual particles, what is the duration of a photon? To illustrate what I mean, consider an extremely low frequency photon - a photon having a wavelength of, for example, one light-minute. Now, supposing you can control the time and direction at which the photon is emitted, you send this photon through an aperture which you are capable of dilating and contracting. At the time at which the photon reaches the aperture, the aperture is large enough to admit the photon. Before one minute has elapsed, suppose, at 30 seconds, the aperture is contracted to a size that the photon cannot move through. Does the photon get through? Is the photon detectable only between the aperture and 30 light seconds beyond it? How quickly can you close the aperture and still allow the photon to pass if the answer is not one minute? Or, does the photon have no transverse length, and always pass, provided the aperture is of a size that would permit the photon to pass at the moment when the photon reaches it? And if this is the case, then how is the information of wavelength carried by the photon? There is a good PSSC video about the experiment that demonstrates that light is made up of particles (which Feynman references) done by John King that illustrates the principles of that experiment very well, but the aperture size and duration in that experiment was nowhere near the scale of the wavelength and frequency of the light investigated. I suspect that the answer is that 100% of the photons get through when it takes 1 minute to close, 50% get through when it takes 30 seconds and so on, because, I suspect, the order of the size of the aperture at which 100% of the photons pass is 1 light-minute in diameter, which limits how quickly you can close the aperture sufficiently, which is maddeningly unsatisfying.
Well thanks to anyone who read this far. I think that's enough questions for one post.
Ma! I just saw a big pile of bullshit on the internet! ;-)

AI should be used to improve picture quality and sound on this. It is a beautiful recording of a wonderful man, and everything he says is still valid today.

The Allan Watts of physical science
What a guy.. so incredibly clever approachable
truly !
Alan Watts! 'A disreputable epicurean.' That was his own rather generous description of himself. More a disreputable charlatan, alcoholic philanderer who couldn't embody any of the nonsense that he purported to be true.
I love this. I'd love to know why the clock works in only 2 dimensions. But i guess he would have liked to know, too.
"....the philosophers that were unable to make that analysis and that idea have fallen by the wayside, through HUNGER"
Imagine Joe Pesci playing Feynman. So, what do YOU think makes light travel at that high speed? What is the length of time that it takes after a particle of light is created for it to get up to light speed? If light travels in a wave form, what properties does it have that make it return and cross over the x axis continuously instead of travel in a straight line? What is the force? What makes Gamma rays able to escape black holes?
He is flat out fantastic. As to this lecture, does he not miss the quantum/point issue?
I have all his written lectures, thank god he was a teacher
I would have received an "A" in this class, but old Feynman never told us "that neatness counts." Thanks, Dick!

The Good News™ is that Feynman lived long enough to see a lot of the results that weren't known in 1979 when this lecture was recorded.
Listening about 10 to 15 mins the beginning of this video I've officially become as smart as a professor of whats he taught me about the subject
Brilliant Man..Sounds like physics 101 direct from the Bronx..
How does this amazing lecture have over a million views and less than 100 comments!?

there's not a lot of corrections people need to make. It's just awesome...
I’ve watched this video a million times...still trying to figure it all out! 😛
I guess.. This sort of content does not appeal to the riff-raff of youtube.

Dude overcorrecting himself at speeds even at that age, he truly was a marvel and an epitome to the scientific method
A true Genius !
I would like him to be there in AI and quantum computing era
That's the worst era
The main factor is that zeroing in on the situations we put our selves into source is always going some where.
He deserved another noble prize
Where's Part 2?
Today, we experimentally know that this gyro-magnetic ratio for muons depends on the mass of the parent quarks decaying I to stable quarks and muons, the phenomenon called muon g-2 anomaly.
Tell that to the guy you order your next chocolate malt from.
I'd rather learn from someone who teaches what he knows, and acknowledges when he doesn't.
Than to learn from someone who teaches what he thinks he knows, because then that will only be an idea.
I agree with this statement
I sense an overwhelming presence of students of pedagogy here.
Wonder what he would think if he knew millions would get to hear this? Congrats mankind......lucky you.

Is there video of the conference of chapel hill with Fehnman debating unified field theory?
I appreciate that Fehnman could bring such abstract and profound theories to everyman's "understanding."
There is no unified field theory, so Feynman could not have discussed it back then.
This man is incisive. Extraordinary. Einstein may look brilliant , but Feynman gives evidence of the light. SurelyTHE BEST EDUCATOR of PHYSICS ever.
Until you read his undergrad textbooks and you are astonished how such a congenial physicist could make so many obvious mistakes. And then it strikes you... he didn't care about teaching.

Who wouldn't love to see the look on the faces of future historians examining this moment in history 🍽
Readers who like Physics. Can you understand this post on the concept of Dimp, the dimensionlesspoint, I am struggling to explain it clearly. This from the next Musea.
1. DIMP stands for dimensionless point - DIM-ensionless P-oint . This is a single point outside the universe, that contains all light! This is a challenging concept and difficult to even imagine. How can anything, let alone all that, be in a point without dimensions? But it's based on what we know now. When you understand my single concept of DIMP, the rest of these physics ideas fall into place. So I will try to explain it in a couple of ways. Read, this section carefully!
Dimp or the dimensionless point is a single point that contains all PHOTONS.
(For visual purposes, think of photons as little pieces of light.) That means Dimp contains all ELECTROMAGNETIC ENERGY in a single dimensionless point. That means all light is in a single point, a point that doesn't have four dimensions, or three, or two, or even one! Pauli's Exclusion Principle is a clue. It says all photons ( a type of boson), can be in one point while their counterpart, fermions, cannot. Remember a PHOTON DOES NOT OCCUPY SPACE! There is no limit to how many can occupy the same quantum state. Photons, all of them, can be in a single point!
By definition we know that photons are outside of time and distance. Infinite time dilation (no time) goes hand in hand with infinite length contraction (no distance to the destination). Because a photon is outside time, it is eternal. Because a photon is outside distance, there is no distance between any two photons. They are all together in an eternal point. They share a dimensionless point! That means all light is in one point.
If there is no distance than photons are everywhere at once - or everywhere at once and back! That means that the photons in the singularity that started the big bang and our entire universe, are here now today, and will be here forever in the future.
Here's an official quote from Physics org: From the perspective of a photon, there is no such thing as time... It doesn't experience distance either.
My idea that all light energy is gathered in Dimp, a single dimensionless point, eternal and outside of space-time, is not easy to comprehend. Let's try this visual analogy. Look at photons, not as individual particles or waves of light, but as a quantum ENERGY FIELD that is everywhere at once, a BLANKET OF LIGHT that surrounds everything in the universe and is in every part of space time at the same time. Still with me?
Because Dimp is eternal and outside time; that means Dimp is these things:
1. Here before the Big Bang, during the Big Bang, and here long after this universe will have ended. A vast reservoir of all energy. And our universe, where there is space and time, is a small subset of Dimp, just as an ember is a small subset of a massive bonfire.
Dimp was the singularity, the dimensionless point, that the Big Bang exploded out of. That means Dimp is separate from, not only time and distance, but gravity, mass, space, you name it! There is no acceleration in DIMP therefore no gravity!. There is no expansion in DIMP and no charge. Further the virtually endless amount of energy in Dimp never changes. That is some weird point!
Dimp, the dimensionless point concept seems to explain all the following separate concepts; COSMOLOGICAL CONSTANT, ZERO POINT ENERGY, VIRTUAL PARTICLES, ENTANGLEMENT OR 'SPOOKY ACTION AT A DISTANCE', AND VACUUM ENERGY.
Dimp also means the electromagnetic force and force of gravity (see later) are not connected. They are separate and can't be unified.
The simplest way to explain Dimp is to start by saying, there are TWO UNIVERSES.
THE FIRST UNIVERSE is DIMP, the dimensionless point, or the universe of photons, light, and energy, where everything that is, goes the "speed of light".
THE SECOND UNIVERSE is SPACE - TIME where everything goes slower than the speed of light. This is the universe of everything that is - BUT photons.
Nothing in Dimp goes slower than the speed of light. Nothing in the universe goes the speed of light. Does that help clarify? BUT WAIT, it gets more strange...
The problem is that to have a "speed of light" one has to have both time and distance. But a photon from it's point of view is outside of both time and distance. From our space-time point of view it looks like photons are going a set distance in a set time, but that is our illusion, not their fact. So "speed of light" is a misnomer. More about this puzzle later.
.
Physics often uncovers a dark zone of unexplained phenomenon. Dimp may help explain those dark zones including:
1. The singularity where the big bang began.
2. Dimp, the dimensionless point of all photons, all light.
3. The dark area in an atom during a quantum jump where the electron instantly jumps over, when it jumps from shell to shell. " Everything in the quantum mechanical universe ... happens in quantum leaps. A quantum leap is a discontinuous transit between quantum states - an electron jumps instantly into another energy level... There is no in between state and it doesn't take anytime for the leap to occur." Moring.
4. The empty zone in an atom where the electron orbital is not.
5. The Two Slit Experiment black bands where no particles/waves land.
6. The nodes of waves where the particle probability is zero.
7. When two mirror image waves collide, constructive interference occurs which annihilates both waves, and turns them into pure energy. Dimp is that pure energy.
8. Virtual Particles where particle A and Particle B pop up out of the void, then come together and there is total annihilation.
9. Quantum tunneling? The space between when Particle A disappears on one side and materializes on the other side.
10. Entangled particles where A and B are strangely and instantly connected no matter the distance between them.
11. Force carriers.
12. the infinities that renormalization tries to fix. With Dimp they are correct as is.
13. Wheeler's Great Smoky Dragon analogy, where A is the head of the dragon, B is the tail of the dragon and the area between is smoke.
14. The 120 orders of magnitude of the vacuum energy density or cosmological constant.
15. Non locality may also be explained by Dimp which is outside of time and space.
Where is Dimp? Everywhere that there is vacuum energy or space, or everywhere!That's because any surface not at absolute zero emits photons, and absolute zero can't be reached. It"s both outside and inside space time! But wait - more weirdness:
PHOTONS DON'T GO ANYWHERE. Remember the speed of light problem? Photons do not move out of dimp! If they did they would have time and distance, which they do not! Photons pop out of Dimp. They are created out of Dimp and return to Dimp. Text books say, the only interactions a photon has, are to be created or destroyed. We see a photon being created or destroyed, but nothing in between! Through pair conversion they send MESSENGERS: Electron / Positron pairs as the energy to do the work . That suggests that electrons and positrons are vehicles for photon energy! That means when a photon pops up in our universe, it does so only as an electron / positron pair!
We know that as an object approaches the speed of light it: becomes heavier and approaches infinite mass, (Infinite mass is also infinite energy, E=MC2). It contracts in length, and time slows. Could that object keep going faster, it would reach the speed of light and be outside of time and be eternal. SO if mass could go the speed of light (and it can only approach it) it would be infinite energy with no length in a single dimensionless point, outside of time! Sound familiar? That is DIMP!
Totally confused? Take a break and try this visual exercise: The light from all stars shine out in every direction with eternal photons that are everywhere all at once.
Look, a web of photons connect all space and all time, now and forever - a net of light!
"dim light less per second" at 40:38 is self-contradictory because less per second is an analog wave. A digital particle stream would be dim light fewer per second.
The really unfortunate thing is that the particle thing is not true to begin with. "Light" does not have any photons. Only the interaction of light with matter creates photons. Which is even harder to understand for the layman because what holds matter together is... light. ;-)
Photon particles are fiction, electromagnetic radiation is waves at all frequencies, never particles.
