Let me explain about "Ramsey numbers", an interesting unsolved mystery with recent mathematical progress, which we can visualize through colorful shapes and analogies about parties!

Also, here are a few bonus "shorts" I released since last episode (I didn't send them to notifications or subscription feeds, so you may not have seen them)

In case people search any of these terms, some of the topics discussed in this episode are: Ramsey numbers (especially "diagonal Ramsey numbers") such as R(5,5), Ramsey's theorem / Ramsey theory, Graham's number, graph theory, complete graphs, the analogy sometimes called the "theorem on friends and strangers", the mathematician Paul Erdos, aliens, computers, and lots more!
