Welcome to the !

A collection of concise study guides to make learning as quick and painless as possible. Topics include, but are not limited to, math and physics.

The goal is to explain the core ideas of each topic, show how those ideas are derived from first principles, and provide links to articles and websites with more detailed information.

Teachers are trees of knowledge. Fruit is free. Will you eat or are you afraid it will bite you?
