Sorry, but I cannot post all of them. Richard Feynman was an inspirational teacher and could illuminate many esoteric concepts in physics with his contagious enthusiasm.
I highly recommend anyone who admires Professor Feynman to pick up a copy of "Surely you're joking Mr Feynman" I couldn't put it down till it was done & couldn't stop laughing. Great book written by the Legendary Genius himself
Started reading "What Do You Care What Other People Think?" Genius explainer. Channeling his father I assume. The power of one human mind. Boggling. = )
Just finished the book and ended up here. I'd heard the name before but never knew how much fun I'd been missing out on. There is a chapter about girls and bars that's a bit off-putting to 2020 sensibilities, but overall it was a great read. Definitely a curious character 😁
Do you know why time only flows in one direction... it's very simple.. as things grow along the Fibonacci sequence, as all populations do, each iteration brings in a different random relationship to the previous iteration .. our Universe, and everything in it, grows today by the same amount it grew yesterday and the day before.. the next number is the sum of the previous two.. it's called the Golden Ratio.. it's the reason things look like they do.. and act like they do.. and it brings randomness to each iteration.. Feynman didn't have fractal mathematics until late in life.. we can only work with what we have.. A Einstein said "in science, we stand on the shoulders of greatness ==>> to see just a bit further down the road
It's amazing how people from all over the world can access this content... wonder if those people back then would've thought that people all over can see this in the future
I hope that I can someday understand physics and mathematics on as intuitive a level as Feynman did. I study daily, and even with my physics degree under my belt I feel no closer to achieving that goal. However, the journey is marvelous!
How did you find doing a physics degree? I’m currently deciding whether to take the physics branch in my NatSci degree and was after some advice or misconceptions or anything you have to say really!
@@curtiskennedy6360 Physics is the best degree to prepare you to learn how to think analytically about things that are directly related to reality. You'll get comfortable with approximations, changing perspectives (coordinate transforms) and seeing the same thing in more than one way (matrix/wavefunction formulation of quantum mechanics). But most importantly, while you're doing this, you'll arrive at precise answers that describe how the world works. If you can throw in as much math into your journey as possible (advanced statistics, sampling theory, etc, which you'll get in statistical mechanics, but it's nice to see it from a theoretical perspective). Differential geometry, topology and tensor analysis will serve you well if you ever need to code anything that requires graphics.
I went the other way for want of mathematical ability (Biology and Earth Sciences). I am now trying very hard to understand Physics. Rutherford was right, but it is still funny that he got a Nobel Prize in stamp Collecting!
That is where I got it. I have been using my time in bed to eddicate myself.. bout 20 years, every day.. the Internet is, probably, the greatest invention in our history
If Richard had ever seen the movie "Endless Summer" he may have known that on the Island of Fiji there is a beach where the surf can be ridden in or out, called "The Ins And The Outs". I am so thankful to be able to see the films of these lectures.
I would like to know the names of those other few that you mentioned. I am not challenging you to do this. I am actually begging you to do this. By this I mean name the ones who have similar talents in teaching or describing such simple yet confusing matters.
So awesome to watch these lectures! Feynman was such a genius. And btw they sound like an episode of the Honeymooners that somehow turns into a physics lecture lol 😂
Prove it, he was one of the species homo-sapien, (unless you meant a human with gonads alone, or both, so excluding biological females) He did indeed possess the quality of intellect, which is the sena quon non of homo sapien sapien, a bit amorphous
00:06 i have one of these 'bell tolls' melodies stuck in my head... i heard it once (another town)... never forgot... i would like to know more about them. And their names...

Damn, there's the REAL Dr. Hugo Pine! Watch the classic 1958 comedy "Teacher's Pet" starring Clark Gable & Doris Day...you'll see who I'm talking about. Feynman in his early years looked like him and, in many ways, he is quite like the character. I wonder if the script writers based the character on Feynman. I wouldn't be surprised, both are highly intelligent people who are very down-to-earth and open-minded. I don't know why I watched that film but I'm glad I did. Feynman ROCKS! :)
i think according to me future can be predicted for those particle which have constant force and constant space time dimenson just like non leaving thing but for leaving thing which can have uncertain force which can very at any time ,we cant predict future easily ,just because we need some more information about this particle ..............and hello guys ,I think future could be seen of any particle whether that is living or non living .........and this day will definitely come soon when every one can see there future ........................ 👀👀👀👀👀👀👀👀
"But I am one-sided. I speak and the voice goes out into the air and doesn't come fucking back into my mouth when I open it." - Richard Feynman, to my bad ears
We did not however, cover the 2nd law of thermodynamics, which in fact discusses entropy. Energy from a high state will seek a low state unless energy is acted upon it. All things seek balance.
When he was talking about the first drawing and he said it looks the me,too forward or backwards. He should have just said it looks the opposite if you record it from the other side. It is equivalent. But fire doesn’t do that you see.
When I drive my car, and look through the front window, I see the future. The car is in the present. I look in the rearview mirror and see the past. It’s so simple.

A pity that only an excerpt seems to have been posted, I was unable to find parts 2 to 5(?). The 45 min. lecture is available though at ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-VU0mpPm9U-4.html

How is the law of gravitation time reversible? If something falls from a spaceship towards earth, then if we reverse time is it going to rise upwards? Feynman explained it for a stable orbit. For anything else the law is not time reversible.
I guess the sense behind "Gravitation is time-reversible" is that if you record the motion of objects in a system affected only by gravity for some time and then play that recording back in reverse at the same speed, you'll find that the law of gravitation is still obeyed. When a ball free-falls from a spaceship to earth its speed starts at 0 and then increases as it gets closer to earth. If you play that recording in reverse, the ball will start close to earth at a very high speed moving away from earth and its speed will decrease as it gets farther from the earth and eventually be 0. Both are consistent with gravity.
@@karthiksurendran7031 How is the second scenario consistent with gravity? Gravity is an attractive force. If you start from high speed and go to zero, you have a repulsive force.
the law of gravitation is time reversible? maybe in the special case of a two-body rotational system, but certainly not for us who reside upon the face of a planet.
Funny you should give an example of a cup breaking and waiting for the pieces to get back together; because once I had a CERAMIC CUP getting knocked off the kitchen counter-top by my cat and it DIDN'T BREAK. The floor is hard enough. I had one witness and he was stunned.
when your cup impacted the ground, the literal first point of contact (by complete chance), happened to absorb enough energy from the force of the impact in a manner that diverted any chance at fracture.
The biggest illusion is apparently consciousness . You just think that you are conscious, having ‘conscious experiences ‘.., But that must be an illusion
@@mattkanter1729 conciousness is also time dependant, one could say its the observer of entropy. If one was to step out of space-time they would see it all and the past present and future would be one.
I didnt watch this now. I watched it then. And always saw it happen in the past. Im pretty sure there's no here and now, nor any future. Just then and there.
The collapse of the quantum mechanical wave function is not irreversible. If one were to collapse a wave, then run time in reverse and uncollapse the wave (if that’s even possible) and then run forward in time and recollapse the wave, the results would differ.
You mean the collapse IS irreversible (from what you write further). If there were "hidden variables", the event could be time reversible, so I think this lecture was held just after Bell came up with his theorem in 1964, proving that there are no "hidden variables" - at min. 6:20 he sais that experiments "of a few months ago suggest the possibility that in fact the beta decay might also not be time reversible". You agree?
@@Gwunderi25 Correct, wave function collapse is not reversible and is irreversible. The irreversible wave function collapse covers everything, including beta decay. I’ll go one step further and hypothesize that wave form collapse introduces new information into our universe, is the source of increasing entropy, and is fundamentally at the heart of dark energy. If you have counter evidence or a counter-factual, I’d be curious to see it?
@@DelonLevi Sadly I can't take any stance at your hypothesis, I'm just a hobby physicist who read A LOT about QM to the point to have a good basic "understanding" of it - but I know way too little about entropy, or dark energy … (But I copied your post, if I stumble upon something later on).

@@havenbastion 🙂 After 2 years, someone comes along with an answer to a question I hadn't remembered asking. Thank you! And as I look back on the question, I'm thinking: Yes. You're right. Like a number of things in nature, they're fundamentally aspects of the same principle.
He said that there doesn't seem to be irreversible laws but surely they knew at that time about Thermodynamics right? The second law is irreversible and fits the description he gave with the weird sounding particles. That this thing changes to that and the whole universe shifts in one direction over time. I can't find the next part but since he started talking about the transfer of energy in friction maybe he was getting there?
(4 years later..)Yep. You are talking about entropy. That was the part he was going to get into but the video ended at the beginning of the entropy part, which has something to do with blue ink dissolving evenly in the water.
Energy, momentum, angular momentum, charge, temperature, pressure, voltage, current, density, force, stress... Dude, don't let physics DK get between you and nature. :-)
«There should be somewhere in the works some kind of a principle that *uxles only make wuxles* and never vice versa, and so the world is turning fron *uxley character to wuxley character* all the time - and this one-way business of the interactions of things should be the thing that makes the whole phenomena of the world seem to go one way.» Does anyone know the origin of this invented word?
Feynman and few others like him were smarter, tougher, morally superior and more capable than most I find today. Feynman volunteered for and contributed greatly to the Manhattan Project as a graduate student, while caring for a terminally ill wife. He learned to crack safes to point out security breaches. He excelled in other fields (Art, Music, and Anthropology). He explained the most esoteric Physics to any audience with an exceptional ease. A "Renaissance Man" if ever one existed.
he also catted around with other women on his wives and with undergrads he had in his classes which would get you fired from colleges today - he was not perfect.
@@meesalikeu You're talking about what could be called a Moral failure, and what's moral/immoral changes with time, place, etc. None of us are perfect, but some of us add to the sum of human knowledge and accomplishments. Fired? So you would have said to fire JFK, Bill Clinton, right? .
Feynman never learned to crack a safe. (SPOILER ALERT: THERE BE SPOILERS AHEAD): He explains in his book that he merely kept a list of safe combinations of some others who were too casual about leaving their combinations lying around. When someone forgot their combination, Feynman pretended to "crack" the safe but he was just looking at the combination that he wrote down. One day, when Feynman was away, they couldn't open a safe so someone from the Safe Company came in to open a safe where the combination was lost. Feynman was ecstatic! He asked to meet this man. Feynman was finally going to meet someone who could actually "crack" a safe. When he met the man from the Safe Company, the man was also ecstatic to meet Feynman. "Feynman!" the man from the Safe Company exclaimed. "I've heard about you! I want you to teach me how to crack a safe". Feynman replied, "But . . . I don't know how. I was hoping you'd teach me!" The man from the Safe Company said that all newly purchased safes come with a standard combination from the company which later can be personalized and changed. Lots of people don't bother to change the standard company combination; the man merely tried the standard company combination and, luckily, it worked. Feynman then went around and tried all the safes using the standard company combination and found that it worked 20% of the time.
"There's a now, a was, and a gonna be. Now is now, and after now is a was. And what comes after the was is a gonna be. It hasn't happened yet. It's gonna happen as soon as the now is over." --Sid Caesar on time causality
if there is never a pause, change is constant and the past is gone and the future has not occurred then what actually is now? Now is basically a snapshot, but it doesnt really exist as it always in the past and is always about to happen. Mind boggling.
An alternative to the past-present-future model is the eternal present. There is only the present moment - only the present exists - only the present has that status - in which things move and change (or appear to do so), and it is eternally existent.
The person with the highest IQ in history, William James Sidis, wrote a book about this. I wonder if it contains any insights that are of value. The book's title is _The Animate and the Inanimate_
