10."I once asked one of my elementary school teachers what a rainbow was, and she told me scientists hadn't figured it out. I walked around until my early 20s thinking that. Also, I think it was this same teacher who told me Columbus thought the Earth was flat. They were training teachers a different kind of way in the '70s and '80s. It's honestly one of the reasons I'm thankful for the internet, because depending on your teacher or an outdated encyclopedia for answers could be a real roll of the dice."
