X-ray machine invented 125 years ago

Physicist Wilhelm Conrad Röntgen invented the device he called x-ray 125 years ago. Röntgen was born in Lennep, Prussia. He spent his childhood and primary education in the Netherlands and Switzerland. He studied at the Zurich Polytechnic in 1865 and graduated as a mechanical engineer in 1868. He received his doctorate from the University of Zurich in 1869. After his graduation, he taught as a professor of physics at the Julius-Maximilians-University in Strazbur in 1876, Giessen in 1879 and Würzburg in 1888. In 1900 he was appointed to the Physics Chair of the University of Munich and to the director of the new Physics Institute. He died in Munich in 1923, four years after his wife's death, in financial difficulties amid the high inflationary economy created by the First World War.

X-RAY ALSO MADE RESEARCHES IN SIDE OF FACULTY MEMBERSHIP

In addition to his teaching position, he was also doing research. In 1885 he announced that the motion of a polarized permeate exhibits the same magnetic effects as a current. Like most researchers in the mid-1890s, he was studying the luminescence phenomenon that occurs in cathode ray tubes. He was working with an experimental setup consisting of two electrodes (anode and cathode) placed in a hollow glass tube called a "Crookes tube". Electrons detached from the cathode hit the glass before they could reach the anode, creating flashes of light called fluorescence. On November 8, 1895, he changed the experiment a little, covered the tube with a black cardboard and darkened the room and repeated the experiment to understand the light transmission. He noticed a glare in the paper wrapped in barium platinocyanite 2 meters from the test tube. He repeated the experiment and observed the same event each time. He described it as a new ray that could pass through a matte surface and named it "X-ray" using the letter X, which symbolizes the unknown in algebra. Later, these rays began to be referred to as "X-ray rays".
