Light is information that gives energy to living things, and energy is the currency the whole system runs on. This is the largest chapter because it powers all the others.
Matter is energy that has slowed and bonded. Speed it back up, and it returns to light.
Let there be light. Light consists of two opposites — a particle and a wave.
Even light obeys the first law: it is a bonded pair, particle and wave at once. It is the energy that gives things life and, quite literally, turns them on. The book takes the oldest command in scripture and reads it as physics.

Shorter wavelength = higher frequency = higher energy.
Energy is laid out as a spectrum, from long slow waves to short fierce ones. Push the wave to its limit and at zero distance the wavelength collapses into pure light — the same singular point the second chapter described, now arrived at from the direction of physics.

The first two pages of this chapter are free. Here are the other thirty-three.
