This is Numberphile. We mainly post videos about mathematics and just numbers in general.
Numberphile is made possible by its sponsors and collaborators.
Jane Street is a research-based trading firm with offices around the world - it shares our love and curiosity about numbers and math (and puzzles!).
They provide amazing career opportunities for exactly the sort of people who watch Numberphile - you can learn more about it here.
Numberphile also has a long-standing relationship with the Simons Laufer Mathematical Sciences Institute (formerly the Mathematical Sciences Research Institute), in Berkeley, California.
Brady is a regular visitor to the institute, where he meets and interviews world-class mathematicians from around the world. Visit their website for more information.
We are also grateful to the Simons Foundation, which is dedicated to engaging everyone with the process of science.
