My friend Robby runs the wonderful Retrokombinat, an Etsy shop full of finds from the flotsam and jetsam of twentieth-century Berlin. For my birthday he made me a card featuring one of a series of collectable science flyers dished out by the Berliner Morgenpost newspaper in 1931. It’s all about brain size, and as you can see, man is most definitely coming out on top here as far as the Berliners of the 1930s were concerned. I was reminded of it when I saw that Epona TV have just dug up an earlier series about the equine brain, which is not so tiny as you may have been led to believe. While on the subject of horse brains, you might also be fascinated by this blogpost from Equisearch, which explains why concussion is a lot rarer in horses than it is in us mega-brain, short-skulled humans. And why horses don’t wear helmets.
