Create a 5 pages page paper that discusses material engineering and the production of x-rays. The concept of X-rays was first discovered by a physicist from Germany called Wilhelm Roentgen in 1895. However, A.W. Goodspeed was the first person to make the X-ray discovery, on February 22, 1890. Because there was no information that could prove that he had discovered X-ray, Goodspeed named his discovery an accident and did not take any credit for the work he had done (Dyson 1). In the discovery, Wilhelm enclosed a glass tube inside of a black paper box. He attached wiring that ran inside the glass tube that resembled the inside of a light bulb. This enabled the electrical currents to build up in the glass tube. He then connected the tube to an induction coil apparatus that allowed an electric current to pass through the tube. This way, a faint green coloured light could be seen across the room. He decided to do this in a different way to be sure of what he had seen. He lit a match stick and discovered that there was a small screen in the room which was coated with a chemical. The lighting from the match stick sent the current along the tube. This made the exact same light to appear again. As he continued with his experiments, he discovered that these rays could penetrate through objects, such as wood and metal. Accidentally, his hand came in contact with the tube one day and saw shadows of his hand with darker shadows that represented the bones. When he moved his hand, the shadow on the screen also moved. He named the shadow the first x-ray picture (Lewin, Paradijs and Heuvel 373).
