Today in history | Birth of the famous physicist Theodore Ryman

On November 23, 1874, Theodore Ryman was born. Ryman is a famous American physicist, spectrologist, the discoverer of the Ryman system in the spectrum of hydrogen atoms, he has devoted his life to the study of far ultraviolet spectroscopy, and has developed a vacuum spectrometer that can measure wavelengths shorter than 200 nm.

Born in Boston, Massachusetts in 1874, Ryman entered the prestigious Harvard University in 1893 to study physics, and stayed on to teach after graduation. In 1906, Ryman and Millikan collaborated to discover the Ryman line system in the far ultraviolet region of the hydrogen atom spectrum, perfecting the study of the hydrogen atom spectrum and confirming the correctness of the combination principle of the Rydberg formula, the Bohr model and the Ritz spectral term combination. The author also gives readers the following science about what is the spectrum of hydrogen atoms, which actually refers to the spectrum obtained by the electrons in hydrogen atoms emitted or absorbed photons of different wavelengths and energies during different energy level transitions. Depending on the energy level at which electron transitions are located, the spectrum can be divided into different line systems, and Raiman found that the first 6 commonly used line systems stand.

In 1919, Ryman left Harvard University and went to the Cavendish Laboratory of the University of Cambridge in the United Kingdom to do two years of scientific research work, here I also popularized the Cavendish Laboratory, which is the first socialized and specialized scientific laboratory in the history of modern science, and has spawned a large number of important scientific achievements that can affect human progress, including the discovery of electrons, neutrons, the discovery of the structure of atomic nuclei, the discovery of the double helix structure of DNA and the scattering of X-rays. In 1921, Ryman returned to his alma mater, Harvard University, as a professor. From 1926 onwards, Reyman served as director of jefferson's Physics Laboratory and was hired as a fellow of the National Academy of Sciences. He died on October 11, 1954 in Boston, USA, at the age of 80. (The picture in this article comes from the Internet, and the copyright belongs to the original author)
