Who is the meanest teacher you have ever had?
My Freshman Football Coach in high school. He was a grade-A asshole.
We were doing drills practicing catching the football. He threw me a pass and I dropped it. He started yelling at me. I went back in line embarrassed. My friend was up next. Coach throws him the football. He drops it, too. Coach says nothing. Annoyed, I mumbled under my breath, “Why didn’t he get yelled at?” Coach: “What was that Doherty?!” (I forgot I whispered like a freight train) Me: “Uhh…” Coach: “Take off, Doherty! TAKE OFF!!!” He didn’t say where to take off to, and I wasn’t going to ask. So, like Forest Gump, I just started running until practice was over.
After practice he came and talked to me. Stephen - the reason I yelled at you and not the other guy is because I expect more out of you. If I am yelling at you, then it’s because I expect more out of you and know you can get better.” It’s when we stop yelling at you when you mess up that you should begin to worry. Because if the day comes we stop yelling when you mess up, it means we’ve given up on you.
Wow. That single sentence by a football coach taught me more about life in one sentence than any other teacher or class ever had. He was the biggest asshole I ever met. But he was the greatest teacher I ever had.

The one who first springs to mind was my PhD supervisor, Ken Crowe. He had a reputation for making grown men cry when they crewed on his racing sailboat, and other grad students were terrified of him, but I was fascinated by the topic he was working on, so I joined his group.
He gave me an assignment: to figure out what was causing muons to get depolarized in liquids. I knew it involved muonium formation, so I went off to learn all about muonium. After a week or two I came to Ken’s office to tell him about it. He listened for a few minutes and then yelled at me, “You have no idea what you’re talking about! Get out and don’t come back until you do!”
So I went away and learned more, better, about muonium. I really got into it, and a week later I came back to tell Ken about it. Again he listened for a few minutes and then threw me out.
Now I was starting to get mad. I bored down on the problem until I understood it so well that to this day it is one of my most proud accomplishments. Then I went back to tell Ken what I had figured out. Again he interrupted me a few minutes into my presentation, at which point I said, “Shut up and listen!” Which he did. And when I finished he complimented me on doing some very original research. From that day forward he supported and promoted me until we became great friends and respected colleagues.
So don’t ever begrudge your “mean” teachers their high standards. They may spur you to accomplishments you will be proud of decades later.
