Irrationality of pi

The number $$\pi$$ is one of the most ubiquitous mathematical constants. It has been studied for thousands of years, and we know all sorts of properties about it and formulas for it. The first hard property of $$\pi$$ is that it is not a rational number. This was first shown by Johann Lambert in 1760. Since then other mathematicians (Hermite, Niven, Cartwright, Bourbaki,...) have found simpler proofs of the irrationality of $$\pi$$. In this talk we will discuss Niven's proof.
