The Most Unusual Ways Pi Shows Up In Mathematics | Can You Explain These?

The video explores the surprising appearances of Pi in various mathematical and physical contexts. It begins with Buffon's Needle, a probability problem that estimates Pi, and moves to Sterling's approximation, which involves Pi in factorial calculations. The video also covers series and products where Pi appears unexpectedly, such as Ramanujan's formula. It discusses the Gaussian integral and random walks, highlighting Pi's role in probability. Finally, it touches on the probability of coprime numbers and Pi's presence in physical constants.
