A Facebook friend recently noted that Turkey was “a remarkably rectangular country.” I wondered how it compared to other countries, and this post shows my answers (Turkey is 15th; Egypt is the most rectangular; full table below). I defined the rectangularness of a country as its maximum percentage overlap with a rectangle of the same area, working in the equirectangular projection (i.e., x = longitude, y = latitude). Ideally each country would get its own projection, but equirectangular rectangles feel at least linguistically thematic and are easier to code…

As we get square, we might send paradigm-shaping birthday greetings to a woman who enabled mapping of an altogether different– and world-changing– sort: Rosalind Franklin; she was born on this date in 1920. A biophysicist and X-ray crystallographer, Franklin captured the X-ray diffraction images of DNA that were, in the words of Francis Crick, “the data we actually used” when he and James Watson developed their “double helix” hypothesis for the structure of DNA. Indeed, it was Franklin who argued to Crick and Watson that the backbones of the molecule had to be on the outside (something that neither they nor their competitor in the race to understand DNA, Linus Pauling, had understood).  Franklin never received the recognition she deserved for her independent work– her paper was published in Nature after Crick and Watson’s, which barely mentioned her– and she died of cancer four years before Crick, Watson, and their lab director Maurice Wilkins won the Nobel Prize for the discovery.
