With sources
Terms and relations say where they come from.
Why does your blood need iron? Why does ice float? Boundless Knowledge shows how things connect: from stars to your body, from music to mathematics.
An encyclopedia explains terms one at a time. Boundless Knowledge explains the links between them. Every term appears once, every relation has an explanation and a source. You start with one question and 3 steps later you are in a different subject.
You enter through 16 worlds, from mathematics to the body and music to cultures and myths. Two of them lead straight on: space to Boundless Expanse, the ocean to Boundless Deep.
Mathematics, Earth, chemistry, the body, language, time, physics, inventions, evolution, dinosaurs, music, art, history, myths. Each world is a room of its own.
Why does ice float? What links multiplying and dividing? The home page suggests questions that cut across subjects.
The knowledge web shows you what relates to what, and you click your way from term to term.
