Find yourself someone who looks at you the way this guy looks at circles. This is true love. It's beautiful.
-
this is a 26 minute video of a man trying to find the relative radius of a circle, and he is very happy too.
-
“If you kiss in real life you have to kiss in the inversion too. Exactly”
-
You should really ask for consent before touching tangentially.
-
This video has instilled me with the very bizarre experience of knowing exactly what you are doing whilst also having no bloody clue what the fuck you are doing.
-
8:35 "Gee you've got good instincts" is my favorite part of the video, the dynamic between these two is hilarious
-
11:59 He said 'Circle inversion!' with the same level of happiness how Hulk said 'Time travel!'.
-
For anyone wondering, the general formula for the area of the nth blue circle (and the nth number in the sequence) will be 1/(15+4*n*(n-1))
-
I'm glad the whole thing came full circle in the end
-
Funny to note that 1/95th is also the portion of this demonstration I've understood.
-
I just love how happy Simon is the entire time, this is a man who truly loves what he does
-
"This is epic. This is seriously epic... This is absolutely epic."
-
Just imagine trying to solve the initial problem, and you think, "quadratic mirrors" and it works
-
I like the part when he said circle
-
Beautiful construction. I suspected the final result from the other denominators: 15, 23, 39, and 63. From 15 to 23 is 1*8. From 23 to 39 is 2*8. From 39 to 63 is 3*8. From 63 to 95 is 4*8. But it's worthwhile to watch him construct the inverted circles and enjoying it.

Rewatching this a year later and man there are just too many great lines (both in terms of geometry and dialogue ;)
-
I can't pretend that I understand it, but I do so much enjoy this guy's enthusiasm! He is absolutely loving it!
-
this guy scares me, he's eroticly in love with maths.
-
It's been 4 years since I first watched this video. I was in high school. Numberphile gave me so much passion for mathematics that I'm now in university. Now, 4 years later, I can finally understand this video.

I love hearing smart people talk it makes me feel smart
