Richard Feynman's Story of Particle Physics - 1973 Lecture 

the best lecture in particle physics you can have !

Beautifully explained (from Feynman) and brilliant drawings (I imagine it wasnt easy collecting all that information!) Congrats!

Richard Feynman. Wish I could have hung out with this guy. No doubt on a par with Einstein. Even greater was his love for the bongos, Mongolia, and strip bars. Not gonna say which is better. All I know is Feynman was a genius and a very cool guy. Richard Feynman and very smart people can explain very complicated things in simple terms that ordinary people can understand. This is the mark of genius!

The world misses this great teachers enthusiasm and curiosity

The first time I have had this explained so that I can understand it. THX.

A hearty thanks to Muon Ray for producing both the audio and supplementing it with video. Feynman was indeed a grand master, and a very eloquent one at that.

A phenomenally great mind. His understanding of so much seems almost intuitive rather than learned - obviously, as are we all, standing on the shoulders of giants, to steal from Newton, but he just makes it all sound so simple. Wonderful! @Muon Ray any idea what year this would have been recorded?

wow, never heard this one before ! thanks !

A hearty thanks to The teacher to Muon Ray~~~~

I wish the 3 Quarks made some albums!

The app. would be 2.3 base 2 height 0.7 in the center.

So do atoms really exist? Or is it just a way to make sense of things around us?

The concept of magnitizim

Higgs boson I'm sure he would have had something to say about it.

I'm from Batavia YES

31:57 wouldn't that be Batavia Illinois ?

I did not understand quark system

Born: 11 May 1918, Manhattan, New York City, New York, United States the late great Richard Feynman would have been 100 years old today, May 11th 2018 - gone far too soon. Respect.

Thanks for posting. I just love listening to this remarkable man.

Although 3 quarks are established, and the necessary gluons, the full quantum chromo-dynamics theory and the Standard Model are still unformed and in their infancy at this stage. There's so much exciting stuff in the immediate future of this recording!

"They disintegrate right away in a very, very tiny time, so we have to deduce their existence." I love the way he spoke.

Fascinating, How am I just now, at 40 years old, discovering the genius of Richard Feynman.....

Thanks Mu! What a fantastic interview. Did you have to do much cutting for clarity or continuity or is this pretty much as is? Feynman responds so quickly some times it's amazing. Truly one of the greatest humans that lived during this life time of mine.

Nice job! Thank you...I show this to people who have no or little knowledge of physics... Would be cool to show HS kids this...Shalom

Wow! The visual aids are spectacular! I wish I would have been blessed with good math and science teachers. Mine were horrible. They seemed hell-bent on demonstrating your "stupidity" and their superior "intellect." That just scared me away. Too bad because the United States needs all the math/science people it can find. The reason I don't hate math/science (even though I'm not good at them) is because I understand they are among the biggest contributors to my health, comfort and economic well-being (relative to the rest of the world), happiness (entertainment and such), and even spirituality (via quantum/entanglement and probably the reason Nils Bohr made his coat of arms a Ying-Yang- Brilliant!) It is very generous of you to share your knowledge, creativity, and effort World-Wide via the Web.

The author of the most beautiful and easy-to-understand physics textbooks I have come across! (i am from Romania)

Thanks for this production. Awesome job.

At 11:24 there is an image that shows Higgs Boson, which has been found, and the supersymmetry, etc. I watched a talk from last year where there are two opinions on physics right now. One is there is no such thing as extra dimensions, and String Theory is only good for selling books and making sci-fi movies. Then you have the otherside who believes the opposite. I can't believe our top physicists act like children bickering over these things instead of working together. It's ridiculous and I can see why no one wants to get a physics PhD. Look at the people you have to work with!

Muon - A Great Big Thanks for all your time to compile the great pics to accompany the audio. Perfect!

A heartly wormly and thankfully I appreciat the Uploader , thanks gentlman !

Wonderful and incredibly lucid lecture on quarks by Feynman

Thanks so much for posting!!!! I love listening to the genius of Feynman, loved the visuals, what a character he was...so brilliant!

This video is so good. Easily in the top 10 most illuminating videos I've seen. Thank you.

That was totally splendid. Great to learn slightly more about all these particles I keep hearing about and see how they fit into what little I currently know of physics.

Hi can you please tell me the date of this lecture? Thank you for restoring it

Thanks for your work putting this together.

Orangejuice!

'We call them Up, Down and Strange... I'm Strange.' What a legend!

Are Feynman and Susskind from the same neighborhood? Their accents and cadence of voice are similar

I try and I try. To get the people in my life. To listen to this man. It never works. If you're an asshole yea yea, you're funny I'll mail you a gold star but if you're smart....Tell me what you think of this analogy. 3 forces being strong & short ranged while gravity is weak & long ranged. Is like having a 1 watt light bulb being visible at a hundred feet. While a 100 watt bulb is only visible to 1 foot. Good? Bad? Thanks.

Omega minus is captured at it's end to answer the freeze

The PET scan must have come from this research.

String Theory was not a waste of time. Geometry is the key to Math and Physics. What if we describe subatomic particles as spatial curvature, instead of trying to describe General Relativity as being mediated by particles? Quantum Entangled Twisted Tubules: "A theory that you can't explain to a bartender is probably no damn good." Ernest Rutherford The following is meant to be a generalized framework for an extension of Kaluza-Klein Theory. Does it agree with the “Twistor Theory” of Roger Penrose? During the early history of mankind, the twisting of fibers was used to produce thread, and this thread was used to produce fabrics. The twist of the thread is locked up within these fabrics. Is matter made up of twisted 3D-4D structures which store spatial curvature that we describe as “particles"? Are the twist cycles the "quanta" of Quantum Mechanics? When we draw a sine wave on a blackboard, we are representing spatial curvature. Does a photon transfer spatial curvature from one location to another? Wrap a piece of wire around a pencil and it can produce a 3D coil of wire, much like a spring. When viewed from the side it can look like a two-dimensional sine wave. You could coil the wire with either a right-hand twist, or with a left-hand twist. Could Planck's Constant be proportional to the twist cycles. A photon with a higher frequency has more energy. ( E=hf, More spatial curvature as the frequency increases = more Energy ). What if gluons are actually made up of these twisted tubes which become entangled with other tubes to produce quarks. (In the same way twisted electrical extension cords can become entangled.) Therefore, the gluons are a part of the quarks. Quarks cannot exist without gluons, and vice-versa. Mesons are made up of two entangled tubes (Quarks/Gluons), while protons and neutrons would be made up of three entangled tubes. (Quarks/Gluons) The "Color Force" would be related to the XYZ coordinates (orientation) of entanglement. "Asymptotic Freedom", and "flux tubes" are logically based on this concept. The Dirac “belt trick” also reveals the concept of twist in the ½ spin of subatomic particles. If each twist cycle is proportional to h, we have identified the source of Quantum Mechanics as a consequence twist cycle geometry. Modern physicists say the Strong Force is mediated by a constant exchange of Mesons. The diagrams produced by some modern physicists actually represent the Strong Force like a spring connecting the two quarks. Asymptotic Freedom acts like real springs. Their drawing is actually more correct than their theory and matches perfectly to what I am saying in this model. You cannot separate the Gluons from the Quarks because they are a part of the same thing. The Quarks are the places where the Gluons are entangled with each other. Neutrinos would be made up of a twisted torus (like a twisted donut) within this model. The twist in the torus can either be Right-Hand or Left-Hand. Some twisted donuts can be larger than others, which can produce three different types of neutrinos. Gravity is a result of a very small curvature imbalance within atoms. (This is why the force of gravity is so small.) Instead of attempting to explain matter as "particles", this concept attempts to explain matter more in the manner of our current understanding of the space-time curvature of gravity. If an electron has qualities of both a particle and a wave, it cannot be either one. It must be something else. Therefore, a "particle" is actually a structure which stores spatial curvature. Can an electron-positron pair (which are made up of opposite directions of twist) annihilate each other by unwinding into each other producing Gamma Ray photons? Does an electron travel through space like a threaded nut traveling down a threaded rod, with each twist cycle proportional to Planck’s Constant? Does it wind up on one end, while unwinding on the other end? Is this related to the Higgs field? Does this help explain the strange ½ spin of many subatomic particles? Does the 720 degree rotation of a 1/2 spin particle require at least one extra dimension? Alpha decay occurs when the two protons and two neutrons (which are bound together by entangled tubes), become un-entangled from the rest of the nucleons . Beta decay occurs when the tube of a down quark/gluon in a neutron becomes overtwisted and breaks producing a twisted torus (neutrino) and an up quark, and the ejected electron. The phenomenon of Supercoiling involving twist and writhe cycles may reveal how overtwisted quarks can produce these new particles. The conversion of twists into writhes, and vice-versa, is an interesting process. Gamma photons are produced when a tube unwinds producing electromagnetic waves. >>>>>>>>>>>>>>>>>>>>>> Within this model a black hole could represent a quantum of gravity, because it is one cycle of spatial gravitational curvature. Therefore, instead of a graviton being a subatomic particle it could be considered to be a black hole. The overall gravitational attraction would be caused by a very tiny curvature imbalance within atoms. We know there is an unequal distribution of electrical charge within each atom because the positive charge is concentrated within the nucleus, even though the overall electrical charge of the atom is balanced by equal positive and negative charge. >>>>>>>>>>>>>>>>>>>>>> In this model Alpha equals the compactification ratio within the twistor cone, which is approximately 1/137. 1= Hypertubule diameter at 4D interface 137= Cone’s larger end diameter at 3D interface where the photons are absorbed or emitted. The 4D twisted Hypertubule gets longer or shorter as twisting or untwisting occurs. (720 degrees per twist cycle.) >>>>>>>>>>>>>>>>>>>>>>> How many neutrinos are left over from the Big Bang? They have a small mass, but they could be very large in number. Could this help explain Dark Matter? >>>>>>>>>>>>>>>>>>>>>>>> Why did Paul Dirac use the twist in a belt to help explain particle spin? Is Dirac’s belt trick related to this model? Is the “Quantum” unit based on twist cycles?

He was still talking when it faded out, does anyone know of a complete audio track?

Feynman says here "What holds the electrons in place? It's the electric force" but the diagram shows it written with the strong force. (7.40) Then he follows "What holds the protons and neutrons together inside a nucleus?" ... "is a mystery we are '(started out?) trying to find out what holds the proton and neutron together". (7.53). Why did he not say simply: "It's the strong force."?

How do you articulate Feynman"s importance to physics? Easy ~•~ " FEYNMAN: EVERYTHING PHYSICS NEVER KNEW IT ALWAYS WANTED. "

Wonderful animations to everything that Prof. Feynman says. Thank you!!!. Thanks for posting. I just love listening to this remarkable man..

Dreadful quality sound recording and constantly interrupted with ads. Gave up watching it after 15 minutes. My advice, find some other documentary to watch.

So, I was thinking about baryons that have no charge & are more massive than Neutrons... & I realized that such a baryon may exist. Its constructed of 1 Charm quark & 2 Bottom quarks. Its called a Charmed Double Bottom Omega (Ω). I am guessing that its probably unstable & Its life is probably very brief. But what if its possible to have isotopes where every neutrally charged nucleon is 1 of these "Super Massive Versions" of a Neutron? Imagine how much more massive the Isotope would be! Now imagine a 14 kg ball of Super Weapon Grade Plutonium 239, about 4 centimeters in diameter; where nearly almost EVERY neutrally charged nucleon is not a Neutron, but a much more massive neutrally charged Baryon: the Charmed Double Bottom Omega. Imagine the energy potential in that ball of Plutonium 239! & if you boost it with a gaseous 50/50 mix of Lithium-Deuteride for fusion?....WOW! Hell! Make EVERY neutrally charged nucleon a Charmed Double Bottom Omega Baryon in the entire Primary Trigger & Secondary!!! The yield would probably dwarf the Tsar Bomba.

Discoverer of quarks couldn't stand Feynman blaming him of being proud for nothing. Picture of the largest collider is a fitting insult.

I think there are endless particles. The fields (QFT) are fluid and elastic. I think the interactions within and about are doing things so infinitely deep that we may never find something to call "elementary". Hearing this discussion and the word "hundreds" as it relates to atomic constituents isn't very reassuring that we have any idea how many elements there are. My brain can't wrap itself around the idea of an electron being singular.

It would be good to know more about this lecture. Where and when it occurred? Is this some kind of teleconferencing event? Who are the audience?

It would be nice if the person (people?) who made this video had shown at least a little competence in dealing with the quality of the audio in the sound track. It's all over the place and even the best parts aren't very good. Makes you wonder about their competence with particles.

As quantum effect to view

Love Richard Feynman! If only the world was made up of more people like him then we wouldn't be in the state we're in today.

Thank you for this great presentation. I work at slac at Stanford in the late 70s. At that point we had four quarks Uptown strange and charm. Two more quarks were theorized truth and beauty. Black 13 Nobel Prize in physics. I worked in the bubble chamber and we are part of two of those Nobel prizes. I will watch this again to learn more about what we are actually doing.

Gluons? ... ancient stuff to think in terms small particles making basic energy units. " ... finding out more about the way matter was constructed." by the interference pattern of imaginations is how. that should be enough, but it seems the one reality always denied.

Particles no more the Primodial substance. My Spinning Genes is the Primodial Substance' that creates all other things.

Thank you, Muon Ray. Excellent job. I find it so interesting that, aside from his immaculately clear explanations, Feynman isn't wrong, despite the age of the interview, just information (that he is fully open to and allows for) simply hadn't been discovered yet. The number of quarks, for example. Fine work by Muon Ray, layering appropriate and accurate info-graphics, etc. And while Dr. Feynman was virtually incapable of being boring, you at least did not leave the picture static. Thanks again.

Thank you for your efforts in restoring this. Excellent work!

Thank you 'I' for producing this video - it really is very very good and clearly must have taken quite some time - Cheers!

AMAZING VIDEO ❤️❤️

Gotta have a little bit of orange juice!

Great lecture. Thanks for posting this. Nice use of graphics too, as I see from reading the other comments that you put them together yourself.

Young James Moore Patricia Lopez Charles

Protons and electrons are + and - and create the damn magnetic field !? When the neutrons are acting as ground 0 between them so they do not colide !? I am noob correct me if I am wrong!

We need you at CERN

This is from the album he recorded over the phone from Sacramento county jail. ☺ Thanks for posting

Brilliant lecture and excellent graphics accompanying it - thank you.

Muon Ray, Great job! Good value addition. I am sure many students will enjoy this lecture even better.

Great video :D Always a delight to listen to Mr. Feynman. Thank you Muon Ray for the hard work :)

One of the greatest human beings that have ever lived

Great diagrams, great editing. Thank you for colorizing mankind's jewel

What remains of these facts following the advent of quantum field theory?

This guy is amazing. I have watched a lot of RU-vid science explainers. This guy is explaining science like how a watchmaker tells you how the watch is made. Such a great explainer. It’s as if he was there when God made the atoms, elements etc etc... I would have paid to hang out with this man

Make it a 7unit

During electron-capture, some electrons nose-dive into the nucleus where a proton captures those electrons before transforming itself to a neutron. On the other hand, during beta emission, a neutron will emit out some electrons to the surroundings. So within a neutron there are some electrons. Why there is no lepton within a neutron? This finding strongly suggesting that the standard model of particle zoo could be WRONG. Electrons have very high velocities while revolving around the nucleus. But we never question why protons and neutrons "don't" seem to have very high velocities? Yes indeed that protons and neutrons also have very high velocities but nucleons would balance themselves out in a unique nucleus structure that their acting forces (such acting force that derived from velocity is coined as angular momentum) balanced out in which it helps to squeeze those nucleons together. So we don't need gluon or strong nuclear force to help explain why and how nucleons stick together within a nucleus structure. Then again, why and how the radioisotopes come into existence? The universe is continued to expand further and expansion needs energy. So as the universe expands more and more angular momentum (kinetic energy) will be transformed to the universal gravitational potential energy to fuel expansion. The weakening angular momentum to certain point will transform some used-to-be stable elements into radioisotopes, and this is how and why radioisotopes come into existence. Again we don't need weak nuclear force to explain radioactivity. Einstein's famous equation, E=mc^2 is wrong otherwise garbage also can be used to make nuclear bombs as long as it is matter or it has mass. Energy and matter can't interchange one another according to Einstein's famous equation. One must have photons before one can emit out photons. Photons are particles and they have mass. Pauli postulated the existence of neutrinos to explain the loss mass and momentum during beta emission. Since photons are particles and they have mass then we don't need the existence of neutrinos to help explain the loss mass and momentum during beta emission. So the existence of neutrinos is bogus. If you are interested in real discoveries, I would recommend you to read my book, The Unification Theory - Volume One and you will be amazed with lots of new, interesting discoveries. In God I trust.

This is enough Feynmam is me and me i like straws.

Wonderful and incredibly lucid lecture on quarks by Feynman. Thanks for posting. I just love listening to this remarkable man..

"Man's curiosity leads him to discover more and more about the world"... R Feynman...but...man's arrogance leads him to conclude that he has found a final answer. My observation of 70 years is that there are far more people who think they have the final answer compared to those whose curiosity allows them to continue to search and question and discover.
