1895165438+1October 8th, which paved the way for medical imaging technology and was awarded the first Nobel Prize in Physics in 190 1 year. This discovery not only had a great impact on medical diagnosis, but also directly affected many important scientific discoveries in the 20th century.
1902: Lorenz (Netherlands) and Zeeman (Netherlands) study the influence of magnetic field on radiation phenomenon?
Hendrik antoon lorentz fills the gap between the classical electromagnetic field theory and the theory of relativity. He is a scientific giant connecting the past with the future and a leader of the first generation of theoretical physicists.
He and his compatriot Zeeman shared the 1902 Nobel Prize in Physics. He also derived the transformation equation of Einstein's special theory of relativity, which is now known as Lorentz transformation.
Iii. 1903: natural radioactivity was discovered in becquerel; Pierre curie (France) and Marie Curie (Polish-French) discovered and studied the radioactive elements polonium and radium?
1903 Mr. and Mrs. Curie and becquerel won the Nobel Prize in physics for their research on radioactivity.191kloc-0/won the Nobel Prize in chemistry again in, becoming the first person in the world to win the Nobel Prize twice. Madame Curie's achievements include initiating the theory of radioactivity, inventing the technology of separating radioactive isotopes, and discovering two new elements: polonium and radium.
Four. 1904: Research and discovery of gas density in argon in Rayleigh (UK)?
Rayleigh is famous for its preciseness, extensiveness and profundity. He is good at doing experiments with simple equipment and can obtain very accurate data. He is one of the few scholars who reached the peak of classical physics at the end of 19, and has made achievements in many disciplines, especially Rayleigh scattering and Rayleigh criterion in optics and gas density measurement in physics.
Verb (abbreviation of verb) 1905: Leonard (Germany) studied cathode rays.
Learnard began to study cathode rays from 1880. 1892, Learnard, then Hertz's assistant, developed a cathode ray tube with "learnard window", which can lead cathode rays out of ionization space, so that the discharge process can be further studied independently.
