Now you ask a question about your leaf. Guess what? You are now a scientist. People will tell you that you have to know math to be a scientist, or physics or chemistry. They're wrong. That's like saying you have to know how to knit to be a housewife, or that you have to know Latin to study the Bible. Sure, it helps, but there will be time for that. What comes first is a question, and you're already there. It's not nearly as involved as people make it out to be. So let me tell you some stories, one scientist to another.
