This 1939 Map of Physics Is an Old-School Mashup of Science and Geography

The journey through Physics can be a treacherous one filled with many setbacks. Thankfully, an enterprising soul decided to sit down in 1939 and draw up a map. The Map of Physics is a "a brief historical outline of the subject as will be of interest to physicists, students, laymen at large," which organizes the field's  many branches into rivers and tributaries. These are surrounded by towns named after important physicists, situated on the appropriate shorelines of their study's focus. Link -via The Big Picture
