Such a genius. He had a great gift of being able to explain very complex systems and theories to folks like me so I could easily understand them. He is greatly missed.
6:21 "The laws of beta decay [...], also time reversible--the difficulty of the experiments of a few months ago which indicate that there's something the matter with--that there's some unknown about the law, suggest the possibility that it may not also be time-reversible, but we shall see." He is talking about the weak interaction in the context of kaon decay. It turns out this is not time-reversible, in a phenomenon known as CP-violation. Unlike P-violation, which is maximal in most weak interactions, CP-violation is very subtle and wasn't discovered until just prior to this lecture series. To this day, CP-violation remains mysterious, but in a different way. Weak CP-violation is explained, but we don't understand why it isn't also violated (to any measurable extent) in the strong interaction. This is known as the "strong CP problem" in physics.
@najtofniBecause that is pretty well known. I have no idea who came up with this multi scale multi level hierarchical paradigm, but Boltzmann was a master of it, and he predates Feynman by eons. This is not a gem like that "there is plenty of space" thing which was Azimov kind of marvelous for the day.
22:06 and on is some of the greatest and most worthwhile oration of any I've heard. wow. in the abstract it applies to all domains of life, even politics
I love how he described the demonstrations of reversible physics at the beginning, and, though they can never happen, how vividly we can picture it all happening.
The most impressive thing is that people actually laughed at the political expediancy joke when most would not be able to understand what he meant if Feynman gave the exact same lecture to people these days. The greatest thing we lost from the past is the depth of thought that people had and the willingness to think deeply about subjects rather than to confidently speculate about those that are outside of your field of expertise.
For beginners ,we learn to absorb it all sort it out later , entropy is not a high school word , I don't need a precise definition , I'm not flying the space ship , I just want to gamble on if it will work .!.
@@u.v.s.5583 but you see there he is describing the concept, without using the the word which refers to it - Feynman repeatedly emphasis this distinction, making the point that you can know many words and yet understand very little and always talking in a very plain understandable way
@@isaacleach1 This surely demystifies the concept of entropy, takes away lots of potential for intimidation and invites thinking and discussion. Other than that... Pythagorean theorem remains what it is no matter whether you use the term 'hypotenuse' or whether you say 'the longest side'.
in Greek mythology... chaos ..was the beginning of order....the chaos was Nyx and Phanes was pre- determined order...... Feynman echos this wisdom!!! :)
Deano Martini as a professor mic drop mitzvah drop. Have you never listened to Yogi Berra or Mark twain Samuel Clemens there is a rhythm to hell they speak. It’s a vibration and it flows. Everyone is looking for the state of flow but only if you can find it. Usain Bolt, one of the fastest runners had an interview and they asked him. How do you run so fast.? He said I don’t wanna fast I keep running the same speed and everything else slows down!
It would be interesting to know more about the mathematical details of Saltpeter's backhanded calculations that predicted the level in carbon. I'm assuming he didn't do it with the Schrodinger's equation but the law that's lopsided in time allowing another method to predict this energy level?
Could we have a probabilistic future coming into existence with the absorption and emission of light waves? We could explain light waves as a process over a ‘period of time’ with particle characteristics or photons as the future unfolds. A potential probabilistic uncertain ∆×∆pᵪ≥h/4π future unfolds with potential photon ∆E=hf energy, of what might happen, exchanging into kinetic Eₖ=½mv² energy of matter, in the form of electrons, of what is actually happening. Light photon energy cascades down forming greater degrees of freedom for entropy and the irreversible processes of Classical Physics with heat energy always flowing from hot to cold and friction always changing motion into heat forming the ‘Arrow of Time’ within each reference frame.
That same thought hit me years and years ago. His voice, his pattern of speech and accent all indeed sound like Norton. (Art Carney's character from the Honeymooners TV series.) So, I am not insane then. Good to know.
+Rasmus Ravn Andersen I think it is. She makes another appearance at 15:37, and there you can see more clearly that she has a ponytail. I thought she was a guy as well at first.
Richard has always been my favorite teacher since the first time I saw him. The best and I love this guy.
It is puzzling to see there are only so few reviews of such a fundamentally important subject explaining the universe.
Such a genius. He had a great gift of being able to explain very complex systems and theories to folks like me so I could easily understand them. He is greatly missed.
People for generations will learn from him if generations want to learn.
@@ericmelton4186 I mean I'm 18 and I'm learning from him, his way of teaching is pretty timeless.
"It's *billions* and *billions* of these atoms."
Love his delivery.
That's one of the best... It's amazing how honest is... pure direct delivery, unfiltered :)
Even that one is TOO MUCH to represent billions and billions of more atoms, considering how many of them in the universe.

Thanks..
so great they made recordings of these
Excellent. No one does it better then Feynman.
That last section of interconnecting hierarchies was inspired. An amazing man.

This is the perfect antidote for all the conspiracy theorists out there durng these difficult times
22:06 and on is some of the greatest and most worthwhile oration of any I've heard. wow. in the abstract it applies to all domains of life, even politics
my favorite of all time!!!
Love this! Now, let’s go get a beer and talk shit about something else for now.
Loved the ending.
"God evidenced in the hierarchy" wonderful ending to an amazing lecture.
I love how he described the demonstrations of reversible physics at the beginning, and, though they can never happen, how vividly we can picture it all happening.
This is why CZcams is great..!
Finaly someone explained entropy to me clearly. With all the ways people tried to explain enthropy It always felt so abstract...
14:17 me every time Richard explains anything 🤣
English subtitles (even automatic subtitles that instantaneously created from video) would be great
+1

Anyone else find the fantastic bit on heirarchies from The Witness?
Yep
what a wonderful question: 'what make time go?'
never thought of it
This guys halarious
" if you watch too closely ,you can't understand it at all " ...I thought it was just me !
Watching 5th time......
Nice
This is a model for all teachers. The word "Entropy" only comes in at 32'.
No, it comes at 3' something. World of a wuxely character is a world with more entropy. Those are absolute synonyms.
For beginners ,we learn to absorb it all sort it out later , entropy is not a high school word , I don't need a precise definition , I'm not flying the space ship , I just want to gamble on if it will work .!.

Great videos, thanks for sharing; but parts 3 and 5 have no sound at all...can that be fixed?
43:00 very true about specialization
Am I the only one that thinks is is Ed Norton's twin ???

Yes
Great video, thanks. Can you please check the sound

"God particle" is a misnomer, then
The electron wave, ... 🥱
The guy at 14:18! :D I had the same expression on my face at that moment! :D

why isn't there any sound?

I bet the nerds heads were just exploding in that room that nite!

OK it is not close to my logic
Typical MS bullsh*t loads halfway and freezes lol
well that didnt age well, hahaaa
