Actually there are two complementing theory of colour vision: Trichromatic Theory and Opponent-Process Theory. These two theories are complementary and explain processes that operate at different levels of the visual system. In the former, there are three types of receptors, each with a...

Let's clarify some concepts: First of all, the current scientific definition of energy if VERY different from the concept of God. Energy can be measured, God cannot. As such, we can quantify energy and not God. That is why energy is part of science and God isn't. Second, when we...

The three different types of cones in our retina have different absorption characteristics as a function of EM wavelength with peak absorptions in the Red, Green and Blue regions of the optical spectrum. The colors we perceive in an interpretation of the information coming to the brain from...

Well our retina respond to a range of frequencies of EM radiation. In principle, couldn't we re-construct a frequency in the visual range with frequencies outside of that range using Fourier Synthesis? Of course using high energy radiation would cause cell damage but ignoring this detail, I...
