WILLHELM CONRAD RONTGEN

1845 - 1923

Wilhelm Conrad Roentgen, the discoverer of X-rays, was born in 1845 in the city of Lennep, Germany. He obtained a medical degree from the University of Zurich, and in the next nineteen years he worked in several universities and became famous as an excellent scientist. . In 1888 he was appointed Professor of Physics and Director of the Physical Institute at the University of Warsburg, and here Rottgen made the discovery that earned him fame. On November 8, 1895, Roux was doing some experiments in cathodic rays. Cathodic rays consist of a torrent of electrons resulting from the existence of a high tension state between electrodes placed at each end of a closed glass tube that was almost emptied of air. The cathode rays are not particularly penetrating and stop after a few centimeters in the presence of air. In this case, Rottgen covered the cathode ray tube with heavy black paper so that no light could be seen leaking from the tube for the electric current to pass. By glowing, it was as if a light had entered and illuminated it. When he turned off the cathode ray tube, the lamp stopped glowing. And since the tube was carefully covered and no light leaked from it, Roentgen concluded that there was a kind of radiation other than that it had come out of the tube when the electric current passed, and because of the mysterious nature of this radiation, Roentgen called it (X) or (X) rays because ( Q) or (X) an algebraic symbol to express the unknown. Roentgen was affected by this result, and he abandoned everything he was looking for and focused his attention on searching for the properties of X-rays, so he discovered the following:

First: X-rays can make many materials glow.

Second: X-rays can penetrate many dark materials, especially note that these rays can penetrate human muscles, but the bones stop them. When he placed his hand between the cathode ray tube and the glowing septum, Roettgen could see the image of his bones drawn on the septum.

Third: X-rays travel in straight lines. In December 1895, Roentgen wrote the first paper on x-rays. His report aroused a lot of interest, and within a few months many scholars, or even hundreds of them, were taken. in research and investigation. X-rays from about In one year, about a thousand research papers were published on this topic! ! . One of these scientists was Antoine Henri Becquerel, who was the first to research on x-rays, but he reached more dangerous results than x-rays (see Becquerel's life). Thus, we see that the discoveries take each other's necks.

Roentgen deserves the honor and full credit for the discovery of X-rays. He worked alone, and his discovery was unexpected, and he followed it carefully and successfully. Roentgen married, but did not have children, but he and his wife adopted a daughter. In 1901 Roentgen received the Nobel Prize in Physics, the first prize given to physics. He died in 1924 in Munich, Germany.
