Brief introduction of Albert Abrahan Michelson's life

Albert Abrahan Michelson (1852- 193 1), an American physicist of Polish origin, was born in Stroyno, Prussia (present-day Poland) in February, 1952, and later moved to the United States with his parents. He was also elected a member of the French Academy of Sciences and a member of the Royal Society of London. He died in Pasadena on May 9th, 193 1.

Michelson was born in the Polish town of Steyr Nuo Ze (then Steyr Nuo Ze in Poznan province of Prussia), a Jewish businessman.

A man's son. When he was only two years old, his family immigrated to America. His father was a businessman, and he grew up in Murphy, a mining town in California, and Virginia, Nevada.

Michelson is mainly engaged in the research of optics and spectroscopy. He devoted all his life to the accurate measurement of the speed of light, and was always an international center figure in the measurement of the speed of light before his death. He invented an interferometer (Michelson interferometer) to measure the tiny length, refractive index and wavelength of light waves, which played an important role in the study of spectral lines. 1887, he cooperated with American physicist E.W. Morey and conducted the famous Michelson-Morey experiment, which was the most important negative experiment and shook the foundation of classical physics. He developed a high-resolution spectrometer and improved the diffraction grating and rangefinder. Michelson first used the wavelength of light wave as the length standard, put forward the possibility of using interference effect in astronomy, and measured the diameter of Betelgeuse star with his own star interferometer.

The Michelson interferometer he created is a great contribution to optics and modern physics. It can not only be used to measure the tiny length, refractive index and wavelength of light waves, but also be an important part of modern optical instruments such as Fourier spectrum. 1926 accurately measured the speed of light by the polygon mirror method.

Michelson won the Nobel Prize in Physics in 1907 because he created sophisticated optical instruments and used them to study spectroscopy and basic metrology.
