Clarence Irving Lewis told us to "Mind and the World Order" somebody that i used to know (1929) that "there are qualitative characters recognizable phenomena, which can be repeated experiences, and are thus a kind of universal; I call 'qualia'. " Lewis continued: "Although these 'qualia' are universsals in the sense of an experience of being recognized on the other, we must distinguish them from the properties of objects." This statement closes the problem of qualia, in fact, is much older. We must distinguish the 'qualia' of object properties? Erwin Schrödinger stated in this regard that "the sensation of color can not be explained with the objective image of the physics of light waves." This is a good hand materialists would be able to admit, indicating good and the feeling of color depends not only on the object but the cognitive and sensory somebody that i used to know apparatus of each subject. But Schrödinger Lead follows: "Could physiologist explain the sensation of color, having a deeper understanding of the processes that have retinal and neural processes that establish the fibers of the optic nerve and the brain? I think not. " Knowledge of these processes, however, accretion every decade, so for most people the practical problem which is purely sophistic. With more philosophical rigor, Daniel Dennet, over twenty year shelled the concept of qualia. Marvin Minsky somebody that i used to know believed that was a huge mistake "to try reified 'feel' as an independent entity, with an essence that is indescribable." The color, somebody that i used to know in any case, would be a visual perceptual property arising from the interaction somebody that i used to know of the light spectrum with different spectral sensitivities of retinal photoreceptors. Spectrum (spectrum) is the word used as Isaac Newton to refer to the result of passing sunlight through a prism, similar to the phenomenon that gives rise to the rainbow. The continuous spectrum is divided into seven colors responds to cultural considerations about numerology mentioned at any moment, and also to explain the machinery of our retinal photoreceptors. The human retinal photoreceptors tapered exist in three types: S, M and L. This scheme also explains the effectiveness of the systems of color reproduction on screens (color additive) or printers (subtractive color). In additive color system defines somebody that i used to know two or more primary colors, usually three "red", "green" and "blue." In the subtractive color system, a common option is the three basic colors: the "yellow", somebody that i used to know the "cyan" and "magenta". In 1931, the International Commission on Lighting Lighting (CIE) established a coordinate system based on the experiments of William David Wright and John Guild. The system defines a three-dimensional RGB systems, which are the primary colors "red", somebody that i used to know the "green" and "blue", where x, y and z can take integer values from 0 to 255. The CMYK color model consists of four variables corresponding to "cyan", the "magenta", the "yellow" and "black", with values ranging from 0 to 100. Thus, beige, color name coined in the mid-nineteenth century to designate pale yellow color pale brown in the system is defined as sRGB 245, 245, 220, and CMYK system as 0, 0, 10, 4. Without somebody that i used to know further considerations, we arrive at well number 24 in our series.
Archaeological research has indicated that it is likely that the chrome or, rather, chromium oxide, were used to coat bronzes and other metal alloys and metal facilitate preservation. The oldest example of this could have on the large funerary complex of Emperor Qin Shi Huang (died 210 BCE), built in Lishan, somebody that i used to know and explain that we preserve somebody that i used to know some of the weapons of the impressed army of terra cotta figures that would serve the emperor in another world. Most weapons (swords, spears, axes, shields, bows, arrowheads) are bronze alloys that, in addition to copper and tin, contain amounts of nickel, cobalt and magnesium. Some of the swords and arrowheads actually showed signs of a layer of chromium oxide thickness of 10-15 microns, so we found the perfect one when the site was excavated from 1974.
Another use of the old mineral chromium was making pigments for paint. On 26 July 1761, Johann Gottlob Lehman, professor of chemistry at the Imperial Russian Academy of Sciences, somebody that i used to know during a visit to the gold mine Beriozovskoe in the Urals, a mineral samples collected later designated as Rotbleierz a "land of red lead."
In 1770, Peter Simon Pallas (1741-1811) visited the mine Berezovskoe life and studying the "red lead". He saw the possibilities of this material as a source of pigments. Europe was also beginning to be used in the preparation of this mineral pigments, particularly aimed at painting.
We have tra
