I learned yesterday the video I made in 2017 explaining how Bitcoin works was taken down, and my channel received a copyright strike (despite it being 100% my own content).
The request seems to have been issued by a company chainpatrol, on behalf of Arbitrum, whose website says
Remember that video about how block collisions can compute the digits of pi? A friend, Adam Brown, just showed that the math underlying this is actually identical to the math behind a very famous quantum search algorithm (Grover's): arxiv.org/abs/1912.02207
Genuinely crazy!
For the most recent video, I had way too much fun simulating the electric field (or rather, the component of that field responsible for radiation) and how it responds to an accelerating electric charge.
The birthday paradox is very famous in probability. If you take 23 people, there's about a 50/50 chance that two of them share a birthday. With 50 people, it's a 97% chance.
We could make many other fun examples to illustrate the same counterintuitive phenomenon (thread).
I have to say, seeing so much of math/science Twitter come to the defense of this video, and the premise of rewarding inquisitiveness rather than mocking inaccuracies, has really made my evening.
