I will watch this video yesterday.

9Ballr i will rewind it and watch again

@@meesalikeu you'll rewind so you'll get disliked😂😂

Any when is fine

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

One of the greatest "autobiographies" I will ever come to read

Just picked up a copy. I've loved all the videos on KZfaq of Feynman and never gave a thought about a book about him.

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 😁

In that sense an impression of these people has travelled to the future. We are all time travellers.

Right, why even bother?

I think there’s a website with all the lectures on it. You should look it up!

Stick around.. Unified Field theory and Grand Unification.. coming up.

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

Part 2 is also available.. I have been busy.. I will post it mañana. 2AM.. sleepless in Phoenix.. slept all day.. getting well is hard work

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!

Keep trying and you'll get there

@@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!

Unless you name is destined to letter the Nobel prize, you'll probably always come up short (like the rest of us).

The voice of Norton!!!

Not surprising. It's a New York accent. The accent isn't as common in New York anymore. But it was fairly common even into the late 20th century.

Bensonhurst!

Exactly! I kept thinking that Ralph and Norton would show up half-way through his lecture. 😂

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.

He should be the archetype of a scientist.

Love that Did you come up with that way of describing past and future ?

@@mjsmcd Yeah. I do metaphysics mostly, which is a lot about Universal Taxonomy - explaining all ideas in relation to one another.

I am smarter, as distinguished from so-called "great physicists" I value TRUTH IN PHYSICS.

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

HA HA HA!

And that is all you need to know about the arrow of time. That is exactly how it works. ;-)

Entropy does not exist, it is a human contrivance and the universe cares not for it

(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.

Smarter.

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.

Yes. They're indistinguishable. Change is an all-encompassing isness.

@@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.

Entropy is 'the arrow of time'

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.

Shame you are incapable of anything then

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.

My goodness how physics has changed!

Energy, momentum, angular momentum, charge, temperature, pressure, voltage, current, density, force, stress... Dude, don't let physics DK get between you and nature. :-)

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).

Dude!

The biggest illusion is apparently consciousness . You just think that you are conscious, having ‘conscious experiences ‘.., But that must be an illusion

@@mattkanter1729 wow. whose quote?

@@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.

qorilla there are no pixels in original video lol

Lazy millenials not paying attention in class...

It's ok, she's hot.

Past presents and future presents, so to speak, would be categorically distinct and remain of cosmological significance regardless.

Pincho Paxton Fluid theory (Reproduction/Feed/Reasoning) decanted selfmultidimentionalover hexagon... The polydynamics of the movement generates pseudo-autonomy as material property, of the autogenous phenomenon; existing.(...) Simultaneous as my unidimensional variability... unidimensional variability = live-beings

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.
