comment Earth and Moon computer simulation
Yes, but how would I do it? Because I start with only the acceleration due to gravity. I can calculate that for every point and find the nett a in the right direction. However, I still need to get it to affect the current velocity, but I doubt that I can simply take the integral. Same for the position.

Ofc its not, and thats my problem. It's either my bounds or the r should be a z. I'm not sure.

comment Liquid crystal polarizes light reflection question
But how exactly? The light with the correct wavelength passes trough unafected, while the rest gets polarized and whatnot. After that most of these crystals have a black layer to absorb everything that comes trough, but why doesn't the light of the correct length get absorbed?
