About us
We make the history of science easy to follow.
One Long Tail is made by One Long Tail, LLC, a small company. We write short, true lessons about how people first figured out the world, one question at a time.
What you will find here
- 428 lessons to read
- Across 5 branches (math, physics, chemistry, biology and the philosophy of science) and 42 eras, from the ancient world to today. Each is a short story of about three minutes.
- 2 hands-on lessons
- Lessons you can drag and tap. We are building more.
- Honest history
- When an old story is uncertain, the lesson says so instead of passing a legend off as fact.

Is it free?
Yes. Every lesson is free to read, and you don't need an account. We are also testing ideas for things we could sell later. They are listed under Plans. None of them are for sale yet, and we never ask for payment details.
