Color - Research Paper Example Color may be quantified and described by the extent to which they stimulate different types of cone cells (Travis, 2003). This is because color perception stems from different spectrum sensitivity of various cone cells in the retina to various parts of the spectrum. The physiological or physical color quantifications do not fully describe the color appearance and its psychophysical perception. The science of color is referred to as chromatography, color science or chromatics (Farndon, 2003). It involves color perception by the brain and human eye. Human perception of color originates from composites of light, photons’ energy spectrum entering the eye. The retina contains photosensitive cells on the back of the eye’s the inner surface. These photosensitive cells are composed of pigments absorbing visible light (Savage, 1998). There are two classes of photosensitive cells: cones and rods. Cones are responsible for human ability to distinguish between various colors (Klein er, 2004). On the other hand, the rods sense light intensity variations and are effective in dim light. Rods sense the flux of no photon energy, the incident photons. Therefore, whenever there is a dim light, human eye do not perceive colored objects as shades of color, but as shades of grey (Travis, 2003). Diagram of color and light Perception of color in the retina is done by photoreceptor cones which are sensitive to photons whose energy widely extend beyond the green, blue, and red spectrum portions (Kleiner, 2004). Color vision is often possible because of the differing photon energy sensitivity of the sets of cones (Savage, 1998). For every flux of photons or color signal, a ration of response in the different sets of cones is triggered. This ration is what permits color perception. During the day, human vision is effectively mostly in the blue-green where the spectrum of the sun is in its maximum region (Travis, 2003). Color sensation primarily depends on light composition, a mixture of colored light and white light (in itself can be wavelength mixture, like purple’s case) (Farndon, 2003). The colored light may have dominant hue or wavelength. The degree to which the wavelength dominates is referred to as chroma, saturation. This saturation, chroma decreases as the white light deletes the wavelength. There are 3 receptors that respond to various wavelengths in the eye. This results in attempts to chart colors via e primary lights mixture. A good number of colors are produces through mixing lights originating from the 3 primary lights. However, not all colors can be produced in this manner (Savage, 1998). Color vision development in human beings is an interesting process of evolution (Kleiner, 2004). The human eye is not in a linear straightforward development. Development of color vision begins as a light sensitive pigment and then differentiates on a smaller creature to create structures that are sensitive to light (Savage, 1998). These light se nsitive structures disperse in the forming eyeball and turns to be the retina. Initially, retina was like a moving sensor. However, it developed the ability to delineate fine details and to see color. The evolution of the eye and color perception is a standard development seen in all vertebrates and many non-vertebrates. So what is color? Why does retina develop ability to see color? (Farndon, 2003). Color is a visual perception that corresponds in human to the categories referred to as blue,

Competition A Factor to Achieve an Excellence Research Paper

Competition A Factor to Achieve an Excellence - Research Paper Example It is a fact that in order to achieve excellence, it is important to raise the bar by competing in a head-on manner. What this will do is to tell the people around this individual that he means business and should always be respected for what he does and how he commits to things which are on the topmost priority for his own self. These are significant undertakings that shall be understood in order to bring in the success which can only come up when the competition has been realized upon. Therefore what is most necessary here is an awakening that competition will bring in the complete usage of strengths and resources, which will eventually tie in a point of success. Since competition is usually doubled with experience that an individual has within his folds, it is always good to realize this point in essence. One must comprehend that business avenues are no different and they have the same competitive rivalry existing within their folds. What is different however is the fact that with in the business, there is a collective effort which is not the case within the individual endeavors that take place on an individual level. Competition is the basis of attaining new achievements within one’s own repertoire, and it helps in assisting one to fathom how he can explore his truest self within the changing dynamics. It must be believed here that competition brings in more good for the people than bad, as it assists one in comprehending the finer details with one’s own strengths and what one can achieve in a given period of time. It is also a fact that competition will raise the bar of expectations within the people as far as an individual is concerned. It makes the people realize how significant this individual is, and how imperative it is to comprehend how this person will take on new ideas and resolve conflicts that mar his very domains. The competition asks of the people to give their best because they want to look different and unique yet excitingly fres h within their approach. What this means is the fact that competition shall bring in success for the individual under consideration as he will derive the best mileage for his own self when he compares himself with the people around him. If people know that they are not within a competitive regime, they will fall flat and not find out what their real strengths are, and how they would move ahead with the changing times. People think differently when they know that they are undergoing a competitive exercise. They start to believe that their undertakings are being closely monitored and that they need to give in their very best time and again, so as to bring value and quality within their tasks and undertakings. When a person does not involve himself within competition with some form of task that he has set his eyes upon to do it in the best manner possible, there would be staleness around him, and he would experience absolutely no motivation to go out there and make a difference, for hi s own self as well as the people around him in entirety. People view competition in a number of different ways and settings – all of which depends a great deal on how they view life and its varied undertakings.
