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 I'm not sure who or what originally made it (maybe one of you know) but it's great.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.”

A better understanding how a sperm swims its way toward an egg could help inform new treatments for male infertility. Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]
Dr Gale Ridge is a public entomologist at the Connecticut Agricultural Experiment Station, where an average of 23 people a day call, write or visit; an increasing proportion of them aren’t inquiring about actual insects, they’re suffering from delusional parasitosis, and they’re desperate and even suicidal.
Biologist Nipam Patel and his team at UC Berkeley study how butterflies develop wing shape and color by performing surgery on caterpillars, creating translucent windows in their cocoons.
The Raspberry Pi Foundation has done outstanding work packing a fully capable desktop computer into a package the size of a deck cards—especially one that only costs $35. But if you already have a working laptop, why should you care? Oh, how much you have to learn. Besides operating well as a compact digital media hub, […]
Custom coffee vessels are the perfect piece of office flair, but it’s just a matter of time before your VOTE FOR PEDRO mug will start to lose its relevant wit. Why not have a new one every day, with whatever silly nonsense you want sticking off the sides? You can save big on your novelty […]
The Lightning port has thus far resisted the cruel fate that befell the headphone jack, and despite rumors that it may be disappearing come iPhone 8, for the present and foreseeable future, Lightning cables are a hot commodity for iPhone users. As such, we must make do in this strange time in which long, glorified […]
