Researchers thought this was a bug (Borwein integrals)

The video explores a sequence of computations that equal π, focusing on the sinc function and its integral. It discusses a phenomenon described by Borwein, where integrals remain stable at π until a certain point. The video introduces the rect function and moving averages, drawing an analogy with integrals. It concludes with an explanation of Fourier transforms and convolutions, providing a deeper understanding of the mathematical concepts involved.
