Sort of tangential, but Democritus was right about atoms, but obviously he worked it out in a very different way to how modern scientists did — though we don’t know his exact reasoning.
Even more tangential: Aristotle (and others) were wrong about the four elements making all matter, but they do correspond to the four basic states of matter, which is kind of fun: earth=solid, water=liquid, air=gas, fire=plasma.
FIFA. Every man and boy in England loves FIFA, except me. I find it totally boring and pointless.
