Tim Berners Lee, inventor of the Web, from the beginning wanted that his invention was semantic forming a global data base of the human knowledge, in which the information could be consulted by all the world and understood by the machines, to generate new knowledge, answer questions and create artificial intelligences that could surpass the Turing Test. This idea begins to become true, but first have to overcome several difficulties that I'm going to expose next. Deep in "The problems of the semantic Web"

The RGB color model is a great invention which allows that with the mixture of different intensities of red, green and blue, any monitor or television can reproduce the colors of the reality. But ... how is it achieve? and why the colors of the model aren't others? The answer is in our eyes.

The retina is the part of the eye where we capture the light, and this is made thanks to a kind of modified neurons for detect photons: the rods and the cones.
