Also the bare eye could see that the quantization was at least 1% accurate, and there was no reason it should have been even that good unless it was von Klitzing's effect.
Higher sampling rates are used because we can afford to do it now, and the higher sampling rates allow lower levels of certain complex aliasing (from amplitude quantization).
It began with Dirac's quantization of fields using the variables of amplitude and phase.
Instead, he applies the standard quantization procedure to twistor theory, the same canonical quantization that has been previously applied to nonrelativistic particles, spin, Maxwell's electromagnetic field and strings.
Subsequent chapters deal with the consequences of this quantization.
This problem is often known as “the quantization of gravity”.
Now, in some sense, the quantization of gravity is an extremely academic (and masturbatory [that's now 2 blog posts, 1 powerpoint presentation!]) problem.
One needs, at the very least, to know quantum mechanics at the level of a two-semester undergraduate course: canonical quantization, operators, wave functions, that sort of things.
The zero point energy of the quantum vacuum results from a quantization condition on harmonic oscillators.
Back to Ch. 33.7 (p. 983), where Penrose implements canonical quantization for twistors.
