What is Brilliant?

Effective learning is interactive, not passive.

Want to get smarter, faster? Brilliant lets you explore great, thought-provoking questions designed to guide you to a deep and lasting understanding of math, science, and engineering.

Brilliant is a network.

Problem solving together is the foundation of all great relationships in the sciences. You can write your own solution and get feedback from people around the world. Contribute a question, edit the wiki, or mentor someone who is learning. Other people will do the same for you.

Go from aspiration to excellence.

Brilliant has quizzes to help you master concepts quickly, a collaborative wiki with conceptual explanations and examples, short and fun video classes, and a network of over 1.5 million members to learn with. People on Brilliant help each other excel.


The mass multiplier

From practical knowledge, we expect things that weigh less to accelerate more quickly than objects which weigh more, when we apply the same force F.

Same force, different effect

Think of what would happen if we use the jet engine of a plane to propel a cruise ship. Although we're providing a lot of thrust, we don't expect the ship to accelerate very quickly because of how heavy it is. Now, think of using the jet engine to propel a waiter to your table... actually, you can just watch:

Learn in bite-sized sessions and level up.

You can track your progress in every subject, and see how you rank among peers around the world.

Inspire others.

"I have learnt much more than what is taught at school at Brilliant. I would like to say thank you to my peers here at Brilliant. You have taught me much from your explanations and solutions. Thank you to everyone here! :)"

"I'm so happy to be selected for the Indian National Mathematical Olympiad. Thank you, Brilliant, for the support and direction. You're all heroes for me."

"I realized that there were some smart kids out there, but I still thought that there were maybe 1000 people smarter than me my age. Little did I know that I was missing zeroes at the end of the number. I was very, very humbled. Since I joined Brilliant 3 months ago, I have doubled my levels in each topic. I tested in the 99.9% percentile on every official math scoring exam that I took. I have been teaching myself as fast as I can. I have received nothing but knowledge by asking question after question. Thank you - you are my inspiration to keep learning."
