Explanation
A scientist is a person with some kind of knowledge or expertise in any of the sciences, like biology or chemistry. See that guy in the white lab coat wearing pocket protectors and experimenting with chemicals? He’s definitely a scientist. The word science comes from the Latin, scientia, which means "knowledge." The sciences are branches of knowledge about the world that derive from repeated experiments. A scientist is any person with an interest in the sciences, from amateurs to professionals. A curious high school student interested in seeing what happens when he slips vinegar into his best friend's can of soda could be considered a kind of scientist!
