THREAD: So, most people associate Japanese design with either cute kitsch or zen-like minimalism, but its much more diverse, & 1 of my particular fav periods was the architecture of its 80-90s boom era; wild, strange & incredibly diverse, & unique in world architectural historypic.twitter.com/oJYgOqgtjb

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): https://arxiv.org/abs/1912.02207 Genuinely crazy!pic.twitter.com/mZKx7gnLQv
