‘Stonehenge was built using Pythagoras’ theorem two millennia before he was born’, I read in today’s paper. A couple of ‘experts’ have decided that one incarnation of Stonehenge included a rectangle marked by 4 stones, which forms a perfect Pythagorean triangle when split in half.
But as the ‘experts’ go on to find perfect 3:4:5 and 5:12:13 triangles in landscape features separated by hundreds of miles, one tends to wonder why they don’t just blame it on ancient astronauts rather than a serious Greek mathematician.
