[QUOTE="985, post: 1232268"] IF you read the White paper, then you understand the physics and this conversation is over. IF you read the white paper and you don't understand the physics, then again, this conversation is over. So, we're done. If you want to take a course in ballistics, its four months in length, (September through December), involves understanding "coupled ordinary differential equations" and "numerical integration techniques," and it's $10K. It covers Modern Optics and ray tracing programs that describes how light moves, i.e. Snell's Law and More, (which does not work the same for all frequencies of light), is the prerequisite to understanding why holding on steep angles, (20+ degrees) with your eye out of the optical center, does not work and is the mathematical basis of what I described in the white paper. "Ray Tracers" actual go back to the principle of "Least Action." What that means is that photons (light) are quantum and operate under the laws of quantum mechanics. Their special. The thing about quantum is that the light particles working its way through the lenses at the quantum level, can actually explore more than one route through the lens. So when you talk about ray tracing, the reality is that the light (photons) sniff their way through the lens in terms of figuring out what is the mechanism that costs the least amount of time that it takes for the photon to get through the system.
