Numberphile is a YouTube channel featuring videos that explore educational topics from a variety of fields of mathematics. In the early days of the channel, each video focused on a specific number, but the channel has since expanded its scope, featuring videos on more advanced mathematical concepts such as Fermat's Last Theorem and the Riemann hypothesis. The videos are produced by Brady Haran, a former BBC video journalist, and feature several university professors, math communicators, and famous mathematicians.
