This was a lot of new information for me. I’m probably going to give it a second watch.
I did think it was funny how they use that parable about Feynman and his professor, acknowledging that it was bullshit. Classic Feynman.
Yeah. I am no physics professional, but it is rare that one of these pop science YouTube videos teaches me some hardcore new stuff. This one is the real deal though.
One of my favorite of the 3blue1brown videos uses that same trick, of summing up roots of 1 in the complex plane so that they spin through the full circle and add up to 0 in every place except where you want them. Seeing that you can do the same thing in the fucking real world to make a laser show up in a different spot from where you’re pointing it is the mother of all mindfucks.
And then everyone stood up and clapped. The name of that student? Richard Feynman.
