The Arithmetic of Clocks and the Mathematical Logic of Time.

A quartz oscillator, an L-C circuit, a grandfather clock, a balance wheel chronometer, the earth spinning, an atomic clock or even the heartbeat of an unborn lamb; they all have one thing in common; the polar-logarithmic arithmetic of clocks. If your life runs by clocks, such as your own circadian body clock, then there can be no doubt about it, you must live within a system that works with polar-logarithmic arithmetic, that is the arithmetic of clocks and the mathematical logic of time. We were all taught arithmetic by "mathematicians" who just take time for granted; quantum physicists should not do this, they need to be more serious.

At the quantum mechanical basis level, the Universe creates a synthetic mirage of forward time progression by forcing historic events backwards into the past. The actual quantum time-state lies perpetually in the present at the observation-horizon of (or threshold of) time-now (an event-horizon).
