Brilliant (website)

Brilliant.org is a subscription-based website and app focused on interactive problem-solving and learning, primarily in the fields of mathematics, science, and computer science. It offers courses and challenges designed to teach concepts through engaging puzzles and exercises rather than traditional lecture formats.

The platform aims to foster a deeper understanding of core principles by encouraging active participation and critical thinking. Users progress through increasingly complex problems, receiving immediate feedback and explanations.

Brilliant's content is structured around various subject areas including foundational mathematics (algebra, geometry, number theory), physics (classical mechanics, electricity and magnetism, quantum mechanics), computer science (algorithms, data structures, machine learning), and logic.

The website features a community component where users can discuss problems, share solutions, and participate in competitions. It caters to a wide audience, from students preparing for exams to professionals seeking to refresh or expand their knowledge.

Brilliant operates on a freemium model, offering limited free content while requiring a subscription for full access to all courses and features.
