Title: A windblown exposition of a trivial concept.
Review: It's well known in computer design that a NOR gate is all that's necessary to implement all other logic functions. Brown develops a simple notation to express NOR and the logic states 0 and 1. Complicated logic expressions converted to their NOR equivalent and expressed in this simplified notation become very malleable. You only have to remember a few simplification rules and frequently the answer is available through simple substitution. I can't draw his notation, but the idea is: Let "(A B)" represent NOR(A,B), "" = 0 and "()" = 1. The cute part is letting empty space represent 0 and the application of NOR to empty space as 1.
Is the review positive or negative?
