Wilhelm Conrad universal gas constant was born on March 27, 1845, in Lennop, a small town in the Rhineland of Germany. His father was a wealthy textile merchant, his mformer(a) was a Dutch bird born in Appledoorn, Holland. During his boyhood years Wilhelm already had a passion for experiments, just above all he loved nature. In tutor he was not very successful, not so much because of his performance only if because of his behavior. He had trouble with his teachers, resisting their authority which finally led to his dismissal. Wilhelm ended his school years without any certificate.Because he wanted to pursue an academic career, he had to let on another way to achieve his goal. A friend suggested the fresh established Poly-Technical Institute in Zurich, Switzerland. There, he applied himself and easily bring in a degree in mechanical engineering. He did not realize what he wanted to do with this degree, so for a piece of music he did nothing. He caroused with his friends. It w as during this time that he met Berthe Anna Ludwig, who posthumousr became his wife. He decided to continue with post-graduate studies with the boost of Dr. August Kuntz.By studying hard and concentrating on the task at hand, he was able to obtain a indemnifyate in physical science with a thesis on gasses. When Dr. Kuntz accepted a position at the University of Wuerzburg, Germany, he persuaded Dr. Roentgen to go with him. In Wuerzburg he could not find work, so he tried his luck in two other cities. Eventually the Institute of Physics at the Wuerzburg University did darker him the coveted professorial chair, which he accepted, and in 1888 Professor Roentgen was elected Chancellor of the University. He taught during the day and spent many evenings experimenting in his lab.On the evening of November 8, 1895, maculation experimenting with electric current flow, using a spark conductor, he generated steep voltages in a partially evacuated glass electron tube. The tube began to g low. He observe that crystals of barium platino cyanide scattered on the table began to give off light when the tube glowed. An experienced researcher, he k advanced he was on to something. however tests showed that paper, wood, aluminum and some other materials were transparent to these strange rays. Even at a distance of 2 meter the rays were still penetrating a wooden door.The professor realized that he was dealing with invisible electro-magnetic rays, which infra certain conditions could stimulate certain materials to fluorescence. He exposed everything he could find of to these strange new rays, among them his weight box, a wire coil in a box and many different materials. He worked like a man possessed and he even slept in his lab. He prove that ply glass is permeable to light but not to these rays, while wood stopped the light, but the rays passed through and through it. Then his thoughts turned towards grind away.The b champions seemed to screen the surrounding tissues . This monumental uncovering enabled man to look in spite of appearance the human body for the first time. Dr. Roentgen was uncertain of the nature of his findings, so he mobiliseed this phenomena X-Rays . He took a grittyly systematic approach to his studies and his experiments. He published a paper about the denudation and in celestial latitude 1895 he held a demonstration with his first X-Ray pictures, along with one of his wifes hand. The discovery caused much excitement in scientific and medical communities passim the world.Scientists in many countries started to experiment with these new rays, and progressive doctors very cursorily used them as a diagnostic tool. A colleague, Dr. Kollicker, suggested in January 1896 to call these new rays after its discoverer. So it was done in Germany, a doctor orders a Roentgen picture, which is taken in the Roentgen Department of the hospital- to this day. During the next decades it became obvious that X-Rays caused injury to variou s human tissue and to vision. radiation was at that time not being related to these new rays. many another(prenominal) researchers developed radiation burns and cancer more than 100 mess died. These tragedies led to greater awareness of radiation hazards for health care workers. early on in the new century X-Ray equipment was being encased, and lead barriers and lead aprons were being introduced after the hazards became known. All this eventually led to a new branch of science Radiobiology. In 1900 Professor Roentgen accepted a position at the University of Munich. One year later he true the first Nobel Prize for Physics for his discovery of X-Rays in Stockholm, Sweden.When his parents died, he genic 2 million marks, which elevated him to the upper classes in the young German Empire. He traveled extensively with his wife to Italy and France, but most practically they spent their vacation in Switzerland. He had fame and wealth and a feudalistic hunting lodge, but Dr. Roentgen was never really happy in Munich. He spent very little time furthering his research. Early in the century tuberculosis was still rampant. X-Ray examinations in mobile units throughout Germany detected the disease early and prevented it from spreading. Soon X-Rays were widely used in medicine, industry and cientific research. It became an important tool in the fight against cancer in the form of radiation therapy, along with surgery and chemotherapy. Today computer imaging is used in medicine and material testing. Since the 1960s X-Ray TV has enabled surgeons to superintend their operations. In the mid 70s micro-electronics entered the field of radiography. Today botanists use computer mental imagery to examine trees for disease, and archaeologists to examine fossils, relics, artifacts and monuments. Dr. Roentgen once took an X-Ray picture of his gas. by chance he had a sense of things to come.One can hardly conceive of airport security today without X-Rays. It is still the onl y devise that get out detect an object of potential danger in luggage or on someones person. X-Rays are not only generated here on footing the universe has been full of X-Rays for billions of years. On June 1, 1990 an X-Ray satellite was launched to explore the body structure and the developments of planets and the stars of the heavens. Dr. Roentgens wife, Bertha, died in 1919 after a lengthy illness, during which he had virtually lived single out in Munich. War and inflation had eroded his small fortune.Wilhelm Konrad Roentgen died intravenous feeding years later, on February 10, 1923 in Munich at the age of 78. His monumental discovery made a considerable contribution to the welfare of mankind. It likewise helps to work the secrets of nature he had loved so well. DISCOVERY OF XRAY. In late 1895, a German physicist, W. C. Roentgen was working with a cathode ray tube in his laboratory. He was working with tubes similar to our fluorescent light bulbs. He evacuated the tube of a ll air, filled it with a special gas, and passed a high electric voltage through it. When he did this, the tube would produce a fluorescent glow.Roentgen shielded the tube with heavy black paper, and constitute that a green colored fluorescent light could be seen approach shot from a screen setting a few feet away from the tube. He realized that he had produced a previously unknown invisible light, or ray, that was being emitted from the tube a ray that was capable of passing through the heavy paper covering the tube. Through additional experiments, he also found that the new ray would pass through most substances border shadows of solid objects on pieces of film. He named the new ray X-ray, because in math X is used to indicated he unknown quantity. In his discovery Roentgen found that the X-ray would pass through the tissue of humans loss the bones and metals visible. One of Roentgens first experiments late in 1895 was a film of his wife Berthas hand with a ring on her finger (shown below on right). The news of Roentgens discovery spread quickly throughout the world. Scientists everywhere could duplicate his experiment because the cathode tube was very well known during this period. In early 1896, X-rays were being utilize clinically in the United States for such things as bone fractures and gun shot wounds.
