Mar 12	comment	How do we perceive colors outside our gamut? I see what you're saying now, I didn't get any of that from the answer. Also interesting might be perception of blue without perceiving red, as red cones have a blue peak as well; this could be what we call violet.

Mar 12	comment	What is the limit to how many satellites can orbit the earth? The GEO satellites are running around the equator, and so are some of the other satellites. Most non-GEO satellites, however, have a different inclination, because the geostationary bit is the main reason to put a satellite above the equator. At low orbital altitudes, the satellite is visible for a smaller area of the Earth's surface, so to reach the majority of users in the northern hemisphere (North America, Europe) they have to have a higher inclination to be any use. These satellites are then less useful for much of their orbit.

Mar 12	comment	How do we perceive colors outside our gamut? @MSalters: Ok, I can believe that there is more to it than independent cone saturation, but regardless of why they are firing or not firing, the signals come from your existing cones, so the brain interprets them as colours just as if there was a light of that colour. My point is that after-images just produce other colours from the same gamut.

Mar 11	comment	How many quarks in a proton? This answer seems reasonable, but perhaps clarify that the infinite quarks are merely probabilistic and temporary. The three stable quarks are the only ones with any importance outside the hadron.

Mar 11	comment	Differential Forms and Densities Integrating over a volume of a charge density will give you a charge. To get mass you would need the density itself (rather than the charge density). So unless you know some relation between charge and mass, e.g. that only electrons inhabit the space and thus go charge density->electron density->mass density, you don't have the right information. Is it a different kind of density you are expecting?
Mar 11	comment	How do we perceive colors outside our gamut? I believe afterimages are simply a result of saturation of the cones, and the resulting lag in their response to intensity changes. The colours you see in an afterimage are still just some combination of red, green and blue, so although it looks strange, it is probably reproducible.
