'The brilliant and entertaining illustrations in this series enliven a clear and enjoyable text that should stimulate serious thought about the world and our place in it.' - Lord Rees, Astronomer Royal

Join Harriet, Darwin's pet tortoise, and Milton, Schrodinger's indecisive cat on a time-travelling quest of discovery, unravelling scientific exploration and religious beliefs and how they fit together.

Throughout the centuries humans have been looking for answers to BIG questions - how did the universe start? Is there a God behind it? Has science explained away the need for a God, or can faith enhance scientific discovery?

On this adventure Harriet and Milton are investigating who the first scientists were. Step into Harriet and Milton's time machine, bring some snacks, and enjoy this curious quest of discovery - become a Mesopotamian stargazer, cast your vote in 'Greece has Scientific Talent', and meet Pythagoras!
