All science is concerned with the relationship of cause and effect. Each scientific discovery increases man's ability to predict the consequences of his actions and thus his ability to control future events. Because women live creatively, they rarely experience the need to depict or write about that which to them is a primary experience and which men know only at a second remove. Women create naturally, men create artificially. You have been warned.
Equations are just the boring part of mathematics.
I attempt to see things in terms of geometry. Everything comes to him who hustles while he waits. The unexpected juxtaposition of the reasonable next to the unreasonable. The easiest way is very seldom the best way. Learn this and you will do great in life.
