Numberphile is a series of films on YouTube dedicated to mathematics and to people with a passion for numbers.
Video journalist Brady Haran collaborates with mathematicians and other experts from around the world, creating videos that range in length from two to 20 minutes. Topics range from the profound to the quirky, and from cutting-edge research to recreational puzzles.
Recent films have included interviews with world-class mathematicians and other math professionals. But the series also features memorable set pieces, including one film in which the first 1 million digits of pi were printed on a mile-long piece of paper, which was then unfurled on an airport runway.
Numberphile is aimed at viewers of all ages and levels of expertise. It has become one of the most popular ‘edutainment’ channels on YouTube, with more than 2 million subscribers and over 250 million views.
