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..

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!

[@curtiskennedy6360]

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!

[@ryanwalter5824]

Keep trying and you'll get there

[@martin-krzywinski]

@@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.

[@Al-cynic]

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.

[@gothicfan51]

[@misonoresoconto]

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.

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.

[@Gwunderi25]

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?

[@DelonLevi]

@@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?

[@Gwunderi25]

@@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).

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.

[@karthiksurendran7031]

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.

[@rishiraje]

@@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.

Kissing numbers are why physics only happen in one direction. If you put a lot of pool balls on a table they are random until they all touch, and then you have an hexagon which isn't so random.
