Some people can "see" equations flow. Probably Phil can.

I can visualize a circuit and see the voltages and the current flowing
around, but that falls apart at any great complexity, and I can
forget, so it helps to scribble the ideas in a bedside notebook.

Some look great in the morning and some really don't.

Some ideas happen in the shower so they are harder to scribble down. I
recall that someone once sold a waterproof sketch kit or whiteboard or
something.
