What is Brilliant?
Brilliant.org is a for-profit organization and associated community that features problems and courses in mathematics, physics, quantitative finance, and computer science. It operates via a freemium business model.
Brilliant offers guided problem-solving based courses in math, science, and engineering, based on National Science Foundation research supporting active learning.
Additionally, Brilliant publishes challenging problems in math and science each week from problems written by members of their community. Brilliant also maintains an interactive, community-written math and science wiki. In 2016, The Atlantic reported that “some of the most recognizable companies in the tech industry regularly prospect” on Brilliant.
