Geim and Novoselov may have for the first time measured the properties of graphene but they did not however discover the crystalline structure. That credit would be given to P.R. Wallace who in 1947 first explored the theory of graphene and propelled the understanding of the electrical properties of 3D graphite. In 1948 graphene materials just a few layers thick were observed with a Transmission Electron Microscope or TEM, by G. Ruess and F. Vogt. In 1962 Hoffman and his colleagues “isolat...

- Discovery canvas is the discovery tool that helps the discovery team to find and arrange any project prerequisites and also helps in identifying different approaches. The discovery canvas guides team through the discovery phase in two ways,: to begin with, it prompts the team to think some fundamental questions. Furthermore, it serves as a visual structure for arranging what the team finds. The discovery canvas is not fixed to a specific necessity theory or methodology. Teams are allowed to pick the methodology that suits them best.... [tags: IPhone, Mobile phone, IPod Touch, Apple Inc.]

- “X-rays were discovered in 1895 by Wilhelm Roentgen, a professor who was working on emissions from electric currents in vacuums. While working, he discovered a glow from the barium platinocyanide coated screen. He continued to experiment and landed the first Nobel Prize in Physics in 1901” (Bansal, 2006). Over the years, many improvements have been made to Roentgen’s discovery and radiography is offered in every hospital around the world. Nowadays, there are many different types of imaging we can do.... [tags: movie making options]

- From the ancient time probably one of the most popular questions among people was how their bones re constructed, and how they are joned. Moreover, it was alsmost impossible for surgeons to identify where in the body bullets can be located and consequently a successful removement of it was equalized to magic. This situation continued until late 1895, when a German physicist, Wilhelm Conrad Roentgen, discovered X-rays, and as a result he invented a mechanism of filming human bones in a picture ( Tice 2007, 1)....

- The Discovery of X-Rays X-rays were discovered by accident in 1895 by the German physicist Wilhelm Conrad Roentgen. Roentgen was already an accomplished scientist with forty-eight published papers. He had a reputation among the scientific community as a dedicated scientist with precise experimental methods. Roentgen had been conducting experiments at the University of Wurzburg on the effect of cathode-rays on the luminescence of certain chemicals. Roentgen had placed a cathode-ray tube, which is a partially evacuated glass tube with metal electrodes at each end, in a black cardboard box in his darkened laboratory.... [tags: Eploratory Essays]

- ‘To Kill a Mockingbird’ Film/Literary Analysis It can be said that To Kill a Mockingbird is one of the most beloved novels of all time. There is something so powerful about witnessing the discovery of good and evil through the eyes of a young girl. While the novel paints a beautiful first-person perspective of Scout’s experiences, I believe that the film adaptation did an equally beautiful job of allowing us to see through Scout’s eyes. One of the key elements that allow us to gain a better understanding of what Scout is seeing and experiencing is through cinematography.... [tags: Good and evil, Evil, Film editing, Long shot]

- The History of Lighting The history of lighting is a very long story dating back before the discovery of fire to the casting of shadows on walls. Lighting like people has both a past, present, and future, that is where our story begins. Lighting is a tricky world to play in for if you have too much, you blinding your subject and if you have too little you can barely see where you are going.

- When scientists discovered that stem cells could be used to repair the human body, they created one of the biggest controversies of all time. Stem cells are bare cells discovered in the human corpse that contain the ability to produce identical copies of themselves for extended periods of time. Stem cells are different because they can operate to specialize into blood, brain, tissue, and muscle cells. Stem cells contain the capability to progress the field of medical treatment in a plethora of ways.... [tags: identical copies, bone marrow, eggs]

- Use of Infrared in Surveillance Abstract: This paper begins with an introduction into the discovery and description of infrared radiation by Sir William Herschel in 1800. It follows by describing various uses of infrared for surveillance purposes. The first application described is the role of infrared in active and passive Night Vision Devices (NVD's) for both military and recreational use. It describes the basic functions of these devices and the differences between the uses and benefits of both active and passive scopes.... [tags: Technology Essays]
