Learn. Teach. Pass it on.

We're making deep scientific intuition free & self-spreading

A kid learns. They teach what they learned to someone else. They challenge that person to do the same.

It's how good ideas have always spread.

Our motto

Be who you needed.

Most of us know what it's like to struggle with learning something. We believe humans can learn anything if it's explained patiently, in sequence, the way a great mentor would.

When we teach kids the way they actually deserved to be taught, we're being who we needed. Then those kids can be who the next kid needs.

Heroes prevent others from going through what they went through. Becoming scientifically deep changes a person's life. This is that, passed forward.

The Teachback Method

Three steps. That's the whole thing.

1

Learn

Read deeply enough that you understand it, not just memorize it.

2

Teach

Teach it back to a sibling, a friend, a parent. That's how you know it stuck.

3

Share

Film it. Post with #EveryoneTeaches. Challenge the next kid.

We're starting with one free book: Science with Sal: Discover, by Sal Shah. The whole story of the universe in an afternoon.
