Something Tom Hull said recently reminded me of an article I keep meaning to plug.
I went to a guest lecture this spring in the math department of the College I work at. This was rather out of character, given my invincible ignorance of anything above the level of word problems concerning red and black jellybeans. Howsobeit, I did attend and was delighted to find I understood everything the prof said, beginning to end. And I also realized that some of what he was describing was what I was doing with the reasoning behind the Smart Waterbomb.
Out upon it: I recommend this article about Mamikon A. Mnatsakanian highly.
It’s calculus for the calculus-impaired.
