Then Everything Changed: Giants of Science

Illustrated stories, for readers 7 to 10, about the people history remembers as geniuses but rarely bothers to explain. Every book follows the same shape: a wrong idea everyone had good reasons to believe, a person who refused to leave it alone, and the moment understanding shifted for good. No one in these books works alone, and no one gets it right on the first try — that's the point, not the flaw.

Currently in the works: Imhotep, Thales, Zhang Heng, Hypatia, and Ibn al-Haytham are in production now, with more giants to come.

For younger readers, the "Raphaël and…" picture book series has its own page.
