Philip Morrison gave the 1968 Christmas Lectures "Gulliver's Travels" which focused on the importance of scale in science. Taking inspiration from Dean Swift's Gulliver in the lands of Lilliput and Brobdingnag , we go on a journey from the fundamental building blocks of the universe to the stellar size of of our galaxy.
