The Wonder Library
Stories, not lessons.
Every post here starts with a real question a kid actually asked, and goes as deep into the real answer as that question deserves. Watch the companion video, read along, or both. Browse by subject below.
Physics Adventures
Circuits, gravity, black holes, the Big Bang — twenty adventures moving from what a kid already half-understands toward the questions that don't have easy answers yet. Some of the best ones are about space, because that's usually where the biggest questions live.

Mathematics Adventures
Numbers were never the point — patterns were. Twenty-three stories about the ideas hiding inside arithmetic, geometry, and the stuff that looks like magic until you see how it actually works.

The same questions, in your hands.
The Library answers a question on a screen. The books answer one at bedtime — picture books built from the questions Raphaël actually asked, and illustrated stories of the scientists behind the discoveries.

The heat appeared from nowhere, out of simple rubbing. That mysterious warmth is friction — and it is one of the most important forces in your daily life.

Patterns and Sequences
Fibonacci · Liu Hui
Look carefully at a sunflower. In the center, the seeds spiral outward. If you count the spirals going clockwise, you might find 34. Count the ones going anticlockwise: you will find 55. Look at a pinecone: 8 spirals one way, 13 the other. A pineapple: 8 and 13, or 13 and 21. These numbers are not random.

Trust, But Go Check: The Traveling Scholar Who Tested Everything
Ibn al-Baitar
Imagine you found an old book that told you a certain plant could heal a wound — but you'd never actually seen anyone try it, and the book was already hundreds of years old by the time it reached you. Would you trust it completely? Or would you want to go find that plant yourself, test it, and see what actually happens?
