This video recounts a lecture by Richard Feynman giving an elementary demonstration of why planets orbit in ellipses. See the excellent book by Judith and David Goodstein, "Feynman's lost lecture”, for the full story behind this lecture, and a deeper dive into its content.

I know what you're thinking: Either Henry is taking some well-deserved time off and I'm just helping to fill in during that vacation, or else he's currently tied up in my basement providing me occasional sound bites for food while I slowly take over the channel for good. To anyone worried about case #2, don't be silly. He's in the attic. Way too many escape routes in the basement.

As Feynman once said "...it takes tremendous strain on the mind to understand certain concepts.." now I know he was right.
-
Ohhhhhh, it all makes sense now. Not to me but I'm sure to someone it does.
-
"What special curve satisfies the property that the tangency direction for a point theta radians off the horizontal is given by this vector from the special eccentric point from the circle to a point theta degrees around that circle from the vertical? Okay... Is the question clear?" Uhhhhhhhhhh... infinite intelligence load error
-
I find it fitting that a guest video was used to talk about a guest lecture
-
“You don’t need calculus to understand this” 3 minutes later “As you can see, if you keep adding infinitely small sections to this polygon, it trends toward a circle”
-
Man, this 3b1b guy (grant sanderson) really deserves more recognition and some prestigious awards. He is one of the most influential math guy in present history, so many people like me are everyday getting inspiration to study mathematics from him.
-
"Stay focused" I see what you probably weren't intending to do there.
-
My head hurts a little, but I think I understand most of it. Remembering it on the other hand.....
-
"Surely you're joking, Mr Feymann !" is one of the best book I have ever read. Its deep, it's mind-boggling, and much more, it's fun !
-
Grant: "Ok? is the question clear?" Me: Nods in liar liar pants on fire
-
3blue1brown: *explanations*, Right? Me: Uhhh brain.exe is not responding 3Blue1Brown: continues explaining Me: brain.exe crashed
-
Newton - "OMG they don't understand my physics!" Feynman - "Hold my beer."
-
Minutephysics + 3blue1brown + Feynman? Knowledge-gasm!
-
Thanks a lot for the video Grant...You really tried your best to keep it simple...even though I had to occasionally pause and ponder. I wish 3blue1brown makes a collection of all the lectures of Feyman !!!
-
Thank you for this! Several, "That is so cool!" moments in this video, and...as much as I love learning...I only went as far as Physics 101 in college. Thus, it's not just cool how all of this works out; it's cool that it can be broken down into individual pieces that are each relatively easy to digest. I'm suddenly reminded of Zen Archery. Don't think about the target; just get each individual step right, and your arrow will arrive at its target "on its own".

I'm afraid I only have a finite amount of intelligence.
-
I've seen this video 3 times already. I understand what he's saying everytime I watch it, and then forget how he did it the next time I come around.
-
Once I get into, and then through college, I'm definitely going to build a time machine and yank Feynman out of some class just to show him this video adaptation of his lecture. Beautifully conveyed!!
