He told me about a cross-country trip he took with his wife and kids in an old Volkswagen bus that reminded me of Little Miss Sunshine. I don't think his trip was nearly so calamitous, but it did sound like fun.
We got to talking about how long people have been doing calculus with nothing more than a feather, some ink, and some paper. He showed me his father's Calculus book from 1919. I think I want to collect antique Calculus books. His father's book was small, leather-bound, and filled with his father's notes in pencil. There was even some notebook paper folded in the middle of the book, and Mr. Tyler wasn't sure if it was his or his father's handwriting. It's amazing to me that this man has Mathematics in his family the way my brother and I have photography and chess boards in ours. The difference being that Mr. Tyler teaches calculus, and I can only take photos with an automatic camera, and I don't even know the rules to chess.
The next week is going to be pretty hectic. I've got two more days of classes followed by three days of finals. Wish me luck!
