Little Hilbert's Hotel
An interactive picture book about infinity, for kids
A free interactive picture book that introduces infinity to kids — based on David Hilbert's famous "Hotel Infinity" thought experiment. The story IS the proof: when a new guest arrives at a hotel where every room is full, every guest moves up one room. The puzzle resolves without ever using the words "infinity" or "set" — but the math is exactly right. Read it free online. Hardcover coming.
I made this for my son. I wanted to introduce him to cool math concepts in a way that's engaging and fun.
Hardcover is in production — there's a waitlist on the site.
Happy to talk about the math, the writing, the illustrations, the production stack — whatever you're curious about.
