Actually, making my own notation is how I start puzzling out any problem. When one reformulates a problem, the appearance keeps changing but the problem is still there. It often takes multiple reformulations to "see" a problem, unencumbered by artifacts of birth.

The other day an EE grad student came to my office to show me his lab's research. After changing notation a couple of times, I was able to recognize that their novel combinatorial problem was an instance of graph coloring.

Can your lectures be shared online?

I would love to watch you create notation.

Richard Feynman did just this and described it at least in his great autobiography, “Surely you must be joking, Mr. Feynman!”
