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- Product idea: An app/website that's identical to YouTube in every way, except without any shorts.
- 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!
00:00 - 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.
00:00 - Food for thought: There exists some smallest whole number which no human will ever think about. I wonder how big it is.
- 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.This Post is from a suspended account. Learn more
- Excerpt from a video I just posted on YouTube (about the multilayer perception layers in a transformer, and how LLMs may store facts).
00:00 - What is a convolution? What is a "Gaussian Kernel"? (This was the main animation used at the intro of last week's convolutions lecture).
