In 1936, Ludwig Bemelmans painted scenes of the Twin Cities to illustrate an article in Fortune magazine. If the style looks at all familiar, it's probably because you're remembering Bemelmans' most famous creation — a Parisian schoolgirl named Madeline.

In this painting, you can see the Cathedral of St. Paul and what I am pretty certain is the James J. Hill House — a massive, red sandstone mansion that is actually across the street and down a half block from the Cathedral. Bonus fact: The Hill House was built by the railroad magnate behind what is now Amtrak's Empire Builder route from Seattle to Minneapolis. In fact, that was his nickname. James "The Empire Builder" Hill. I'm not kidding. The house is open for tours and it's pretty fantastic. Plus, you get to watch a nice video which assures you that while James J. Hill was, technically, a union-busting robber baron, he also really liked kittens. Again, not kidding.

I love this Map of Physics that turns an entire academic discipline into a fictional country, showing the way different sub-disciplines interact and the concepts that connect seemingly disparate discoveries.

Posted by Frank Jacobs at The Big Think, it dates to 1939. I'm not sure who or what originally made it (maybe one of you know) but it's great.

The map is more than a random representation of the different fields of physics: by displaying them as topographical elements of the same map, it hints at the unified nature of the subject. “Just like two rivers flow together, some of the largest advances in physics came when people realised that two subjects were [like] two sides of the same coin”, writes Jelmer Renema, who sent in this map.

Some examples: “[T]he joining of astronomy and mechanics […] by Kepler, Galileo and Newton (who showed that the movement of the Moon is described by the same laws as [that of] a fallling apple.” At the centre of the map, mechanics and electromagnetism merge. “Electromagnetism [itself is] a fusion between electricity and magnetism, which were joined when it was noted by Oersted that an electric current produces a magnetic field, and when it was noted by Faraday that when a magned is moved around in a wire loop, it creates a current in that loop.”
