CentoZeri: Numeri Giganti

From 1 all the way to infinity: a journey to discover how big numbers can really get — with Doc Aleph, games, experiments and wonder.

How big is infinity? And a googol? Can there be a number so large you couldn't write it even using every atom in the universe?

CentoZeri is a journey from you all the way to infinity. One stop at a time, each number becomes something you can truly grasp: how much all the ants on Earth weigh, how many stars are in the Milky Way, how many ways there are to shuffle a deck of cards. Your guide is Doc Aleph.

• 26 stops, from you to Graham's number and infinity • "Guess and reveal" games and hands-on experiments • The stories of the mathematicians who invented these numbers • Simple words, made for children but fascinating for grown-ups too

CentoZeri doesn't teach you to do sums: it makes you want to look at numbers the way you look at the night sky.
