History of scientific thought as a tube-map

Crispian Jago has created a delightful map of the history of scientific thought, superimposed on the iconic London Underground tube-map: "500 years of modern science, reason & critical thinking via the medium of gross oversimplification, dodgy demarcation, glaring omission and a very tiny font." I love it, but I fear for poor Crispian, giving Transport for London's notorious penchant for censoring tube-map takeoffs with abusive trademark threats.
