Murray Gell-Mann, Jewish American physicist, passes away

Murray Gell-Mann (89), a Jewish American physicist who theorized the existence of the quark and won a Nobel Prize for his method of classifying particles, has passed away in New Mexico on May 24, 2019. He transformed physics by devising a method for sorting subatomic particles into simple groups of eight, based on electric charge, spin and other characteristics. He called his method the “eightfold way” after the Buddhist Eightfold Path to enlightenment. Later he developed the theory that identified “quarks,” indivisible components of Earth’s matter that make up protons, neutrons and other particles.
