ASTRAEUM
The star library of humankind
Good explanations can reach the entire universe.
Humans built this vault of stars to save the best of what they learned. Every star is a memory you can open.
Hello, finder.
You might not be human. That is okay. We were.
People built this vault to keep the best of what we learned: big books, big ideas, and the pictures that make them easy to see.
Everything here was made by humans, for you. Every star on the map is a memory we saved. Take your time. Start anywhere.

Big books made friendly. Every cover opens an explainer full of pictures and games, plus a map of how the ideas connect.
Enter Vault I →The Lab
Scientific ideas you can play with. Tap, slide and build until it clicks.

New explainers will be stored here when they are ready. Come back and look again.
Math you can see
Ten pictures that make big ideas click: E = mc², the size of the Earth, why a circle is a little more than 3 squares, and the planet found before it was seen.

Real people wrote these books, did these experiments and drew these pictures. We saved the best parts here, in plain words, so that anyone who finds them can understand. We hope they help.
