Progress of Essay #4: Gaps in the Spectrum

When I first came up with the idea for this essay, my immediate thought was that I wanted to challenge myself. The subject material, which concerns the use of the colour spectrum to determine the elemental makeup of stars, is not common knowledge, and I have no right to say that I know a lot about it either. However, I have found that the subject greatly intrigues me, and it leaves me with a yearning to know more about it.
             Part of my essay discusses the various types of light, and how the human eye is incapable of detecting most of it. An idea which came up randomly while watching television was to demonstrate how blind we really are. To do this, I turned off all of the lights so that it was pitch black, held the remote facing my phone's camera, and took photos when I pressed any of the buttons on the remote. At the tip of the remote is a receiver, which communicates signals via infrared light. What is clearly visible is a blue light being detected by the phone as a result of translating otherwise invisible light frequencies into light that humans can perceive. I have included one of the photos within my essay.
             I do not intend to give away all of the science within this post before the essay is handed in, but this is an idea that I'm very happy with, because it means that instead of simply reporting what I have researched about other peoples' work, I have personally demonstrated the science.
             In terms of the flow of the essay, a lot of it may be based in history, telling the story of how one piece of evidence led to another, when, where, how, by whom, and under what context, because for example, had Sir William Herschel not left a spare thermometer for the sake of measuring standard room temperature while measuring the temperatures of the individual frequencies of the colour spectrum (ROYGBV), he would have never discovered infrared light.
             I feel it is good to use history as a means of explaining the development of science and gradual gathering of evidence, especially within the context of this essay, which is entirely based on direct evidence.
