I have talked a little about myths recently and seem to keep stumbling over them.
I am really starting to question everything I ever been taught!
For example, I was taught that people during the Middle Ages in Europe thought that the Earth was flat and not spherical.
Well it turns out, it's another big, fat myth as explained here in Wikipedia and again here. It seems that since the third century BC, few educated people in the western world have believed the earth to be flat - expect of course members of societies such as the Flat Earth Society.
