People are very surprised by these rays. Almost everything is transparent to them. With these rays, they can clearly see their bones and fingers, and there is no meat ring. It can penetrate substances that ordinary light can't penetrate, so it caused a great sensation in society and brought a revolution in the medical field.
The person who discovered this special light was wilhelm konrad rontgen, a German physicist, who was born in Lane Nep, Lanzhou on March 27th, 1845. At the age of 3, the whole family moved to the Netherlands and merged into Dutch nationality. He moved to Switzerland on 1865 and studied in department of mechanical engineering, Federal Institute of Technology in Zurich, Switzerland. 1868 graduated and 1869 received his doctorate. After that, he worked as an assistant to the singer Conte. /kloc-returned to Germany in 0/870 and taught at the University of Wü rzburg and the University of Strasbourg.
Roentgen won great honor for his discovery of X-rays, and won the first Nobel Prize in physics for his discovery, so he is also famous in the world. However, he has also made outstanding achievements in many fields of physics, such as the magnetic effect when the medium moves in a charged capacitor, the specific heat capacity of gas, the thermal conductivity of crystals, thermoelectric and piezoelectric phenomena. But these contributions are mostly ignored because of the achievements of X-ray.
X-rays were discovered by accident. At that time, Roentgen was conducting cathode ray experiments. To avoid interference, he sealed the pipe. To his surprise, for the first time, he found that the small screen of cyanoplatinum and barium near the X-ray tube glowed, which aroused Roentgen's great interest. He studied continuously for several days, and finally determined that the light emitted by the fluorescent screen was caused by some kind of ray emitted by the ray tube, which is a new ray that is little known. Because little was known about the nature and attributes of this ray at that time, it was temporarily called X-ray, which means position.
Later, Roentgen continued his research and experiments, published several papers on X-rays, and photographed the hand of a famous professor at the University of Wü rzburg with this kind of rays, which caused a sensation all over the world. Roentgen therefore received invitations to give lectures from all over the world, but with one exception, he politely refused all the invitations because he wanted to continue studying its X-rays.
The only exception is the German emperor. He showed his X-rays to the emperor and won a medal.
Roentgen is a modest and noble man. At first, Professor Crick proposed to name the new ray he discovered "Roentgen ray", but he always insisted on using the name "X ray". And resolutely refused to pay a high price for their own patents. The Nobel Prize he won was also given to the University of Wü rzburg as a research fund.
Roentgen devoted himself to science all his life, and he was very indifferent to material interests. He was the first person to win the Nobel Prize. His only regret in his life was that he signed the declaration of German militarism in 19 14. He was very upset about it, and he felt guilty about it until February 1923 on the eve of his death in Munich.
