Feynman's Lost Lecture (ft. 3Blue1Brown)

I think this is clickbait I never did see any lost lecture with Richard Feynman just a bunch of b***** from some stupid idiot

Although this is not a proof, it is possible to program a simple elliptical orbit as dr/dt in a loop. This formula would be in x,y,z,t space and requires only an origin. Not as proofy, but useful for simple radial mechanics.

Would that mean that, if the sun was in the centre of our orbit we would have a circular orbit and not an elliptical?

I wonder if using Fourier transform were easier 🤔

Is an ellipse not just the shape of a chord through a sphere with one end along a diameter, and the other inclinated at some angle with respect to the diameter?

Do we oscillate perpindicular to the plane of orbit such that the average of all the rotated elliptical orbits generates a circle in the plane or orbit?

if we observe that acceleration is perpendicular to the velocity vector, can we get a regular polygon (circle) map of acceleration vectors from the velocity regular polygon (circle) map? after rotating and turning the velocity map into an ellipse? This is just for extra CPU processing after I finish digesting this video....

This is an outstanding presentation - What software did you use to create the plots?? thanks

It has to be like this because the sum of all interior angles in a triangle is always 180 degrees.

I am so confused but I'll come back to this later when I've approached infinite intelligence.

You mean he lost it, we lost it or he lost it during the lecture & in a way a Fine Man shouldn't.

Appreciate the explanation as I know there are a lot of proofs of Kepler's laws, but I have found very few videos explaining Newtons conclusion on why orbits must be ellipses. That part of the story where Halley requested his analysis has always fascinated me. Thanks

Grant you are an awesome teacher even for a Ph.D

Dear, I am a mathematics teacher from Sichuan, China. Can you tell me what software are used to make these video animations? Thanks

Feynman was from Queens, not Brooklyn!!!

Black holes really screw this up.

Oh my god, straight lines from a point, create Elipse, sphere.

Omg this problem is hard both with calculus and without it 😅

"Remember that all you need to follow along is infinite intelligence." Lol

this was literally just a 3b1b video lmaoooo

Lol; amazingly intuitive and simple presentation of an outrageously complex topic. Orbital mechanics being explained using basic geometry, entry level integration, and wonderful diagrams.... wayyy better than how i had to learn this stuff 😂. Now we just need to add in quantum effects, gravitational [relativistic] effects and time dilation, and dynamical friction and we're good to go! 😅 conceptually though, this is probably the best introduction to this you could ask for.

I need to watch it again and again to help my low IQ to get it all in.

I program microcontrollers, and once was figuring out a way to ramp a motor up or down in a smooth way when I figured out that if you start with some point x,y and some velocity Vx and Vy, you can write a simple program that adds to Vx and removes the same amount from Vy, and it will trace a portion of a circle. with some simple tweaks it draws a complete circle. with no visible trig functions and a simple ballistic-physics-like script I was surprised to see circles and ellipses form. It turns out you can create a discrete-time-function orbit simulator on a computer with just a few lines of code.

Your dads think they're smart

Please, do not pronounce foci as 'fosai', but as the latin requires is: 'foki'....

Why does background music have to be added to everything these days? 🤔🙄

I fucking love smart people. God do I love them so dearly.

bruh

What happens if you do this at the center? Just a smaller circle emerges?

It isnt foco in latin it is focus. Focus means hearth, fireplace, altar, stove. The plural is foci. Foco is a dative or ablative of focus

can someone tl;dr this?

nope not a scientist racist hchewish freemason lodges and coommunistr int activities

if I had infinite intelligence I would not need that lecture

Well I'll be damned

Videos like this make me wish I were more intelligent or that I had been born long enough ago to have had an original interesting thought to share with the world.

Goods observations! Congratulation.. 2023.06.12

Verdient zeker meer erkennning

Are electron orbits elliptical in an atom by the same argument?

😮

❤

Let’s see some Hakini Mudra, Triad Claw, covert Hail Satan, etc

Im just curious. Technically this means that the orbit can still be a circle, right? Besides, circles are basically ellipses, just with some additional properties

the change in velocity vector that is constant implies that accelaration in tangential direction is constant but in radial direction its always changing that is change in the velocity vector along radial direction (accelaration in radial direction) is propotional to radius^2 so it could form some other polygon same thing goes when you tie a bicycle tyre rim to a string and rotate it

While Feynmam was a Genius and a brilliant person, pls remmember he basicaly created his own formula writing equations? Which tbh i never understood 😅😊
