1. Background Years ago after I returned to work following surgery and lymphangiograms and more surgery and radiation therapy and chemotherapy for cancer, a colleague sat with me at lunch. “You know, chemotherapy isn’t natural,” he said.

1. Read the Instructions I walked over to their desk when they raised their hands. “Mr. Hasan,” one of them asked, “can we just write our work for problems 2 and 3 over here?” They pointed to the right of problem 1. “No,” I said. “What!? We can write small!” “Did you read the instructions?” […]

1. Ambiguity In the abstract it’s a fair question. Does this mathematical notation (2,7) represent a point in the x-y plane with coordinates x=2 and y=7? Or does it represent an interval on the number line extending from x=2 to x=7? The notation by itself really is ambiguous. 2. Clarification When he called me over, he […]

The poor man. Not invited to the party with its fancy festivities and marching military parades. Unable to hobnob with his besties, Xi, Vladimir, and Kim. He whines that they are conspiring against us. Conspiring. You think!?

1. Are Those Your Books? As the room was emptying, a student walked up. There had been many questions that first day of class, questions about rates of change and concavity, about what the diagram really meant. I figured she was following up. “Mr. Hasan,” she said, “are those your books?” I put down the […]

At a “random public boat ramp” on Lake Huron, Gregg and Kelley say that they found this view to the east. It was a sunny day. The sky and lake were blue. They had the place to themselves until some fishermen showed up. And then there was this. What is it with chairs and lakes […]

Ada Years ago I dove into the programming language Ada. The NASA lab was funding me was deep into it, but they were far away, and no one here was interested. Here, it was either FORTRAN, or it was C. But I had drunk the Kool-Aide. Ada was difficult to learn in isolation but not impossible. […]
