When I was in high school, I didn’t have a lot of interest in science. I was a slightly rebellious, somewhat bored, occasionally disruptive student. My biology teacher, Mr. Niwa, finally reached his wits end and suspended me, permanently, from class. “Mr. Walmsley!” he boomed, “You don’t need me, and I certainly don’t need you. I want you to leave this class, now. Come back at the end of the semester and take the final.” Great, I thought. I don’t know what any of this crap ha
