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.

In 2018, Haran released an audio podcast titled The Numberphile Podcast.[1]

YouTube channel

The Numberphile YouTube channel was started on September 15, 2011. Most videos include Haran interviewing a knowledgeable subject as they explain a mathematical concept, usually with the assistance of a marker and large piece of brown paper. It is supported by The Mathematical Sciences Research Institute (MSRI) and Math for America.[2][3]

The channel was nominated for a Shorty Award in Education in 2016.[4] The New York Times has said, "At Numberphile, mathematicians discourse, enthusiastically and winningly, on numbers".[5]
