Newly Found Feynman Lecture: The Strong Interaction, 1977

[@craigwall9536]

The thing I like about Feynman is that his mutterings reveal HOW he's thinking- I mean the way he talks to himself with his inner voice; checking himself and making mistakes and trying again. None of that polished shit that most people present to the world- Feynman is as natural and real as it gets. He doesn't hide his ego or his disgust or his hopes or his satisfaction. You can hear it all because he never shuts up and I find it absolutely delicious.

[@rovidius2006]

Very well said sir ,a honest scientist .

[@TurtleTube123]

His character was such that he didn't consider that he "knows" something if he can't pull it out of a hat! :)

[@manmeetworld]

What do you care what other people think? Further adventures of a curious character.

[@paxsreekantan3639]

Well said. That's precisely how you realize someone is not just saying something, but speaking the truth.

[@dalepoco]

omg just found this. I was there. As a member of the group of Physics majors at SFU at the time, I met him, shook his hand and spoke with him for several minutes over beers in a room of the pub after the lecture. A life-highlight.

[@logaandm]

Me too! I remember a small lunch in the department after this lecture.

[@oingo2]

[@squarerootof2]

​@MichaelKingsfordGray My name is Dale Mucho. I'm his cousin and he's telling tbe truth. My cousin is an Incel, hence his name.

I’ve spent this rainy day watching Feynman lectures. Jeez, what a terrific teacher. Love his thick, Brooklyn accent. He has the timing and cadence of a comedian.

[@richardt9831]

16 years +/- after this was recorded, I took my undergrad physics lectures in this very classroom. I had no idea at the time I was sitting in such hallowed halls!!

[@speculawyer]

Thank you. I can never get enough Feynman.

[@minkymott]

You beat me to it. I was going to say the exact same thing. :)

[@paulmichaelfreedman8334]

U mean you need your daily Feynman Fix? :P

[@minkymott]

Exactly. :) I'm always looking for Feynman videos. My favorite so far is when he talks about looking at a diagram with some other people, and he accidently, correctly, identifies a valve on the diagram and they think he's a genius because it was out of all these diagrams he just happened to pick the one that was the valve. He had no clue about what this diagram was about. I wish I could remember what it was about. I laughed the whole time.

[@fredlockard4509]

+minkymott - lol ya... I think that valve thing might have been in "Los Alamos from Below"? not sure tho :p I think he was talking with Leslie Groves about plutonium extraction or something like that

[@billyhack9673]

Where can I find a copy with correct brightness and contrast?

[@zuzusuperfly8363]

I don't recall seeing this one before! Thank you for posting it. Finding a new Feynman lecture always gets me excited. Don't worry about the sound or video quality. As long as I can hear him, my ears get used to the sound anyway.

[@entropy7888]

Understood under half of it but loved every minute of it. That's what a great teacher can do.

[@smcic]

That hug at the beginning...

[@noapology88]

Thought he was about to propose...

[@mickobrien3156]

I don't get most of this. I have no training or fancy education. But any existing videos of Richard Feynman, and I'm watching. If I'm ever going to grasp the Strong and Weak forces, it would be from him. So... I'm all ears.... Thanks for the upload.

[@Epoch11]

The most annoying thing is not seeing what he puts up on the projector, but thank you for uploading this anyways.

[@michaelmcneil4168]

I wonder if there is a mimic somewhere who could redo these or just have some actor that knows the physics go over it in a proper studio. If there are any creative types in colleges I think they have to have their creativity kicked out of them before they are allowed pieces of paper to show people how clever they are instead.

[@gokurocks9]

Someone alive today was here and they remember... I'm sure of it..

[@lefonddeenfer9844]

it is not a problem, you can find those multiplets on the internet. But you need the oldest one. Back then they thought there are only 3 quarks, so they constructed multiplets for barions and mesons using only u, d and s quarks. General comment - I realize how it is complicated to explain things which nobody understands. He simply throwing facts to them and it is absolutely okay because what he is talking about was discovered few years before the lection. Many questions remains unanswered up to this day... i love high energy physics

[@maulcs]

Just look up "Richard Feynman at Simon Fraser University: The Strong Force" on YT for a better quality version.

[@Franciscasieri]

Anyways isn't a word...in any language...but complaining about the most trivial of matters in a sea of beauty is the voice of a narcissist...and should be called out as such...

[@stevenverrall4527]

I ignored the video and simply listened to the fascinating audio! It is amazing how little has changed in the intervening 46 years. The most relevant physics to our existence are the low energy nuclear interactions of normal matter. This is only just beginning to be understood. For example, "Ground State Quantum Vortex Proton Model" published in Foundations of Physics on January 23, 2023.

[@BlackEpyon]

Don't worry about the quality. I'm into retro/vintage computers as a hobby, and like any field involving old things, you restore what you can, but you also learn to take what you can get. We're fortunate enough to have this, never mind how much the VHS has degraded over the years.

[@glutinousmaximus]

Cutting edge stuff at the time! I would have loved to be in his class!

[@glutinousmaximus]

In the questions towards the end, it becomes plain that the theory (CED) is incomplete about the interactions between quarks and gluons; and whether a quark can exist on it's own - in other words, if you pull strongly enough (pour energy into) the 3 quarks, then at some point (we know now) a new proton will be created rather than the original proton being pulled apart! Great post - Thanks!

[@michaelmcneil4168]

Does he ever explain where the pressure comes from in the centres of stars?

[@BartAlder]

Thank you so much for this wonderful upload. For sure the audio isn't great, video is not great either... but the lecturer definitely was.

[@michaelmcneil4168]

How can you tell?

[@BartAlder]

I read his Lectures on Physics.

[@williamtachyon2630]

I read those as well right now. I can't help it, but when I read them, the voice in my head sounds just like Feynman's :)

[@solapowsj25]

Power part-ons from proton particles. Very interesting and illuminating.

[@georgesmith4639]

Amazing that anyone could understand all that, let alone have it memorized for a lecture. There must only be a handful of people on the planet who understand QM at the level Feynman did.

[@TheEmergingPattern]

It's not so difficult, on the lowest level it is matrix mathematics. It is supposed to as basic as possible to explain the observations. But it doesn't feel like a human observation or experience you can relate to ordinary things in order to say: yes I understand! It needs a leap of faith

[@nedanother9382]

I'll bet a REALLY small handful for sure

[@kockarthur7976]

Woah, I actually haven't seen this before.

[@bennylloyd-willner9667]

[@paxsreekantan3639]

You guys can't figure out how to clean up this video so the slides are legible? C'mon man - they're priceless!

[@navneetmishra3208]

I mailed Neil Alberding for the original tape.( www.sfu.ca/physics/people/faculty/exafs.html ) Neil Alberding: I’m sorry, but I don’t have access to the original tape now.

[@FlockOfHawks]

If there weren't 6 but 8 quark flavors , it would only take 3 *whatsits* to describe them - where the whatsit is a 2state solution to some extremely weird differential equation , probably . I came close to insanity when i studied QM , and my teachers weren't anywhere near as charismatic as Mr Feynmann , fortunately , so i had the option to drop out . Now , the stress has gone , and i can safely enjoy this Genius and share our fascination . Thanx for uploading , Friend !

[@FlockOfHawks]

If we increase the energy by another factor of 10^9 , we witness phenomena that require a 4th whatsit , which isn't all that bad , for now we can introduce the thingy , two of them , combining to these four . Big Bang must have been waaaay beyond weird .

[@paulk.bowden7134]

I couldn’t see anything on the screen

[@shmul953]

It it dangerous listening to Feynman because right after you end one video you go immediately to the next one and before you know it, there goes you whole day. I do have a question though: Is what he's explaining still correct? is all still relevant to today?

[@fastundercoverkitgoogle7381]

Without being a physicist I can tell you that some of the stuff here is outdated. Some new particles have been discovered and the measurements of the masses of the particles have been improved. If you want to watch up to date physics videos on youtube that explain complicated concepts with simplicity I suggest you watch the videos on Fermilab's channel (those made by Don Lincoln, there are some extra stuff on that channel too)

[@manifold1476]

Most of the stuff is still accurate, but there are no known nucleons with three down quarks or three up quarks. If there were there would be things other than the proton and the neutron in the nucleus of some atoms, one particle with the charge of an electron but with a mass about that of a proton, and a "super" proton, with the charge of two protons but with a mass about equal to one proton.

[@sudarshanbadoni6643]

I am not a man of physics of this highest order though studied hydro dynamics. The zeal and cheer to Express is amazing. Spring small butterflies are just in emergence state up wards and the coordinate parameters flight path and energy levels formations mapped and in sucha complex state precisely. What more I can say.thanks.

[@docpedersen7582]

Why can't CIA, NSA, FBI et al apply their super enhancement processing to videos like this?

[@mehranshargh]

good point ;) maybe they don't watch as many movies as we do!

[@RWBHere]

You cannot enhance something which s not there. It would be great if someone who was at that lecture could reproduce the diagrams from their own notes in another video, and set it to the soundtrack of this one.

[@BlackEpyon]

Because that "super enhancement" only exists in the movies. If, for instance, the video or audio were noisy, you could introduce a noise filter, but in averaging it, you'd loose fidelity in the process. If you try to sharpen the picture, you will enhance the digital artifacts from the conversion to the point that it becomes hard to watch. You can't enhance what isn't there.

[@johnries5593]

The question would be, how good of a use of taxpayer dollars would it be to try? In any case, Dr. Feynmann's voice is loud and clear and that strikes me as the most important part.

[@BlackEpyon]

What's the use spending taxpayers money on it if you can't enhance what isn't there without guessing as to what missing details are? You can make an artist's impression, but if accuracy (detail) is the goal, then you're still dealing with a lack of relevant data.

[@geniusmchaggis]

didnt understand a word of it... COOL tho! love the feynster!

[@chrimony]

Yeah, too much particle zoo for a layman to watch. I couldn't get 20 minutes in.

[@sumanbashyal365]

The picture is too blurry, can you please make it more clear using AI. To honor our great scientist, Sir Richard Feynman. Thanks. Sincerely. Suman Bashyal

That era? It's just as likely to be 1/2" reel-to-reel or Umatic.

One has to congratulate American colleges for persisting in making very low grade videos and then losing them then finding them in time to present them as precious finds. Does anyone on here know how they do it and why?

[@apburner1]

Interesting. What is your theory on CANADIAN college films such as this one?

[@michaelmcneil4168]

> What is your theory on CANADIAN college films such as this one? Wouldn't that depend on what part of America Canada is in? Newfoundland is for the dogs and Labrador is ...never mind. I think Canada is some sort of a small boat isn't it? (But I may be confusing it with Horsetralia.)

[@williamglover6031]

General lack of organization.

[@RickarooCarew]

thanks for sharing this priceless lecture.. I am.. checking his work.. so.. if, as Dr Feynman told us.. all particles are spheres.. why.. do they spin.. in various directions. at higher and lower energy states?... please respond with the idea that.. there's no such thing as magic... if we can't measure it .. it's not there.. without the math it's just blah blah blah

[@RickarooCarew]

as an example.. Planets occupy a place in the magnetic field of the sun which goes round and round every 80 days along with its magnetic field.. this creates a magnetic field line that is going round and round along with the sun, but it is also revolving around it's own axis, perpendicular to the ecliptic.. which creates a warp in space-time and planets roll around it.. it's a mechanical response to the magnetic field of the sun and its motion along the Sagittarius arm of the galaxy... it's definitely not magic

[@RickarooCarew]

Dr Feynman is quoted as saying.. we start out checking other people's work.. one day we realize.. no one has done this one before... so it is.. standing on the shoulders of Giants.. to see a bit further down the road.. thanks Feynman family... ad Infinitum

[@RickarooCarew]

born on Sandia Base near Los Alamos.. my father was army.. they assembled the weapons tested in New Mexico in the early 50s.. I have been a student of physics for 65 years.. my father taught me simple calculus when I was 3... he could do the math.. it was simple.. I got my own slide rule for.. an educational toy.. he taught reactor theory at the graduate level in Washington DC... at Catholic University.. oy vey.. no lightning.. nada.. he told me he was a pacifist.. after 68 years.. I believe he was.. how bout that?.. RIP Col Carew.. Peace ☮️🕊️ please 🙏

[@RickarooCarew]

quantum foam was predicted in 1957.. experimentally verified in 1964... that's where quarks come from.. experimentally verified in my laboratory for about 3 years now... no magic required my thoughts follow Occam's razor

[@RickarooCarew]

if all particles are spheres.. why do they do what they do?.. why do they create brownian motion?... Feynman diagrams allow us to predict the behavior of a particle with a particular energy and its interactions with other particles in a very accurate way... the math works... but spheres at a McDonald's kiddy pool require kids to make them... jiggle.. to bounce around.. and they don't spin at all, except, perhaps, by accident....? we use strange.. and charm... to discribe... spin.. and properties of motion ... continuous motion.. that carry energy... it takes energy to do work... so...
