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 our place in the universe. Step into Harriet and Milton's time machine, bring some snacks, and enjoy this curious quest of discovery - from the Islamic Golden Age to the Renaissance, and meet Galileo!
