Numberphile
Numberphile is an educational YouTube channel featuring videos that explore 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, the Riemann hypothesis, and Kruskal's tree theorem. The videos are produced by Brady Haran, a former BBC video journalist and creator of Periodic Videos, Sixty Symbols, and several other YouTube channels. Videos on the channel feature several university professors, maths communicators, and famous mathematicians. In  2018, Haran released a spin-off audio podcast titled "The Numberphile Podcast". YouTube channel. The "Numberphile" YouTube channel was started on September 15, 2011. Most videos consist of Haran interviewing an expert on a number, mathematical theorem, or other mathematical concept. The expert usually draws out their explanation on a large piece of brown paper and attempts to make the concepts understandable to the average, non-mathematician viewer. It is supported by the Mathematical Sciences Research Institute (MSRI) and Math for America. Haran also runs the "Numberphile2" channel, which includes extra footage and further detail than the main channel. The  channel was nominated for a Shorty Award in Education in 2016. "The New York Times" has said, "At Numberphile, mathematicians discourse, enthusiastically and winningly, on numbers". Contributors. The channel has featured mathematicians, computer scientists, scientists, and science writers, including: Section::::"The Numberphile Podcast". Haran started a podcast titled "The Numberphile Podcast" in 2018 as a sister project. The podcast more heavily focuses on the lives and personalities of some of the subjects of the videos.
