On CPU Physics and CPU Cycles

This draft chapter examines how CPU physics and architecture affect computational efficiency, explaining that access speed decreases with physical distance due to parasitic capacitances rather than the speed of light. The article details typical CPU components and operation cycles, noting that simple operations like addition take 1 cycle while multiplication takes 3-6 cycles and division up to 20 cycles, and that modern CPUs use pipelining and multiple ALUs to process operations simultaneously.
