INTRODUCTION
Invisibility was one the most sought after abilities and fantasies from the Invisible Man, and Harry Potter to the Predator movies; it featured significantly in science fiction. In reading the article, ‘Scientists create invisibility cloak’, it can be seen that the ability continues to be sought by scientists today. To try and achieve this researchers are looking at and deepening their understanding of the nature of light. The modern research carried out are elaborations of the work done by Thomas Young and Francesco Grimaldi who’s work formed the foundations of our current understanding of the nature of light.

Waves and Interference
Wave motion is said to be the most common type of motion; it’s the cause of sound reaching our ears, light reaching our eyes and electromagnetic waves to our radios and televisions, along with disasters such as tidal waves and earthquakes. Wave motion can be defined as a, “…mechanism by which energy is transported from a source to a distant receiver without the transfer of matter between the two points” (Besancon, 1990) and are classified by how they are produced, for example, a vibrating material or an electrical oscillations in an aerial. The most important classification involves a medium’s direction of motion (a medium is a substance that the wave is travelling through) or in the case of electromagnetic waves the direction of motion of the electric or magnetic field. This direction is in reference to the direction of energy in the wave itself. (Besancon, 1990)
Wave motion can be considered as one of two types of motion; longitudinal motion and transversal motion. In transversal motion the movement is in an up and down motion or ve...

"The Lord of the Flies": Shining a Light on the Evil Inherent in Human Nature

- How do we, as humans, define civilization. What is it that exemplifies our commonality as a species and sets us apart from the common beast. Is it art, science, literature, technological advances, or the philosophical mind. In the Lord of the Flies, Golding successfully unravels our delicate perceptions about what makes us human through a series of haunting and powerfully constructed symbols; among the most integral are the beast, the Lord of the Flies itself, and the fire. Through his narrative, illumination is cast upon the evil inherent in human nature, and society is revealed as a weak and easily penetrable façade....   [tags: Literary Analysis]

Essay about The Scarlet Letter : Nature Vs. Nature

- Nathaniel Hawthorne’s The Scarlet Letter: Nature vs. Nature One of the central themes of The Scarlet Letter by Nathaniel Hawthorne is the idea of how nature bridges a connection with human beings. In the novel, it can be thought that Hawthorne portrays nature as a human like entity. That is, in the novel, nature, much like a human, is capable of observing, responding to, reacting to, and interacting with the characters. That being said, in this case, nature goes by both definitions of the word: nature as the wild, untamed outdoors, as well as human nature....   [tags: The Scarlet Letter, Nathaniel Hawthorne, Light]

A Perfect Proportion Of Light And Color Essay

- A perfect proportion of light and color in modern architecture a very intriguing, but I believe is underrated and could be used much more than we do today for various reasons. More particularly, homes should use more natural lighting along with our overly zealous color schemes for a fuller beautiful blend of lights and shadows. For instance, poverty areas around the globe have started using water filled plastic bottles, installed in their roofs and walls, as a means of cheap natural lighting. Ghettos mostly in 3rd world countries have recently been using plastic bottles to create head lights, wall lights and a means of illuminating their homes, since most of these areas don’t have any sourc...   [tags: Light, Color, Bottle, Lighting]

Essay about The Nature Of A State Of Nature

- The thought about a 'State of nature ' is the genuine trap of presence without government, without a state or laws. To imagine a state of nature, we imagine away government, law, police, and we find what we have left. The idea has a long history in political theory, in light of the way that it can help us answer the inquiry, why might it be prudent for us to, live under the rule of law. In common life, we disparage it that we do, that there are things we are not allowed to do, laws we should not break, that if we do, we will be rebuked, and that these matters are picked by different people....   [tags: Political philosophy, Law, State of nature]
