In addition, quarks are the only known particles whose elementary charge is non-integer. Every flavor of quark has a corresponding antiparticle called antiquark. The only difference between antiquark and quark is that some of its characteristics are the same size as quark, but the sign is different.
Quark proposer
Murray gell-gherman, one of quark supporters, was born in a Jewish family in new york, USA. I have been interested in science since I was a child. /kloc-entered Yale university at the age of 0/4, 1948 transferred to MIT after obtaining a bachelor's degree, and obtained a doctorate three years later, aged 22. 195 1 year, gherman went to work in the Institute of Advanced Studies of Princeton University.
1953 Lecturer, University of Chicago. Participating in the research group with Fermi as the core, gherman went to California Institute of Technology as an associate professor of theoretical physics on 1955, and was promoted to full professor many years later, becoming the youngest tenured professor of California Institute of Technology.
George zweig, another quark supporter, was born in a Jewish family in Moscow, Russia. He originally wanted to be a particle physicist under the guidance of richard feynman, but later he turned to study neurobiology. He worked as a scientific researcher at Los Alamos National Laboratory and Massachusetts Institute of Technology, but switched to finance in 2004.
