These are my favourites. #Platonicsolids Fun fact back in the early millennium research suggested the universe was shaped like a dodecahedron. #Plato #minerals #autumn #nature #naturephotograpy #creative

#JohannesKepler was a brilliant #astronomer who studied the motion of #planets. Like everyone, he also had some strange ideas about the heavens, no doubt as a person in the middle ages would about the harmony of worlds and their purported relation to things like the #PlatonicSolids, which was of course bogus. He is probably best known for his famous three laws of #PlanetaryMotion which he reluctantly formulated when he had to abandon the idea that planets only orbit the #Sun in perfect #circles.
