I. 1901: R?ntgen (Germany) discovered X-rays
Discovered on November 8, 1895, X-rays paved the way for the pioneering of medical imaging technology, and was awarded the first Nobel Prize in Physics in 1901. This discovery not only had a major impact on medical diagnosis, but also directly influenced many of the major scientific discoveries of the 20th century.
Two, 1902: Lorentz (Netherlands), Seeman (Netherlands) on the magnetic field on the effect of radiation phenomena?
Hendrik Anton Lorentz bridged the gap between classical electromagnetic field theory and the theory of relativity, and was a scientific giant between classical and modern physics, a leader of the first generation of theoretical physicists.
He shared the 1902 Nobel Prize in Physics with compatriot Seeman***. He also derived the transformation equations underlying Einstein's special theory of relativity, now known as the Lorentz transformations.
Three: 1903: Becquerel (France) discovers natural radioactivity; Pierre Curie (France) and Marie Curie (Polish-French) discover and study the radioactive elements polonium and radium?
In 1903, Mr. and Mrs. Curie and Becquerel won the Nobel Prize in Physics for their research on radioactivity***, and in 1911, won the Nobel Prize in Chemistry again for the discovery of the elements polonium and radium, thus becoming the world's first two-time winner of the Nobel Prize. Mrs. Curie's achievements include pioneering the theory of radioactivity, inventing techniques for separating radioisotopes, and discovering two new elements, polonium and radium.
Four, 1904: Riley (UK) gas density research and the discovery of argon?
Riley known for rigor, breadth and depth, and good with simple equipment for experiments and can obtain very accurate data. He was one of the few scholars who reached the peak of classical physics in the late 19th century, and has had results in many disciplines, including, in particular, Rayleigh scattering and Rayleigh criterion in optics, and gas density measurements in physical properties have had the most far-reaching impact.
V. 1905: Lenard (Germany) on cathode rays
Lenard began to study cathode rays in 1880, in 1892, Lenard, who was then an assistant to Hertz, developed a cathode ray tube with a "Lenard window", which can guide cathode rays away from the ionized space. This device guided cathode rays out of ionized space, allowing further independent study of the discharge process.
