Quarks are a type of elementary particles and fundamental constituents of matter. In 1963. Gell-Mann and Zweig proposed that none of the hadrons. not even the proton and neutron, are truly fundamental but instead are combinations of three more fundamental pointlike entities called quarks. In the quark model, all hadrons are made of a few quarks. The quark theory is well-accepted today, and quarks are considered fundamental particles. . . #physics #physicsmemes #physicsjokes #physicsmeme #science
