Gell-Mann, the American physicist and "father of Quark," died at the age of 89

According to the "Central News Agency" on May 27, the California Institute of Technology said that the 1969 Nobel Prize in physics winner and American physicist Gell-Mann died on the 24th at the age of 89. Gell-Mann was honored for his discovery of quark particles and his contributions to particle classification methods.

Murray Gell-mann is regarded as one of the most important physicists of the 20th century, and in the 1960s he proposed that subatomic particles (neutrons and protons) are composed of "quark" particles, hence the name "father of quarks".

Experiments later confirmed the existence of quark particles, and quark particles have been the subject of continuous research by physicists, including the large hadron collider (LHC).

Born in New York City on September 15, 1929, Gell-Mann studied physics with the encouragement of his father and received his Ph.D. from the massachusetts institute of technology in 1951. He taught at caltech from 1955 until his retirement in 1993.

In an obituary published at the California Institute of Technology, Hiroshi Ohri, a professor at the California Institute of Technology and director of the school's Walter Burke Institute for Theoretical Physics, wrote: "Dr. Gell-Mann has insight and keen insight to quickly navigate large amounts of experimental data and understand the meaning of the data" and "He has created a new paradigm for particle physics."
