1979 Nobel Prize-- GLASHOW, SALAM and WEINBERG
the theory of the unified weak and electromagnetic interaction.
1984 Nobel Prize-- RUBBIA and VAN DER MEER the discovery of the field particles W and Z, communicators of weak interaction.
Ancient times People think that earth, air, fire, and water are the fundamental elements.

4. Physicists are human beings
1898 Joseph Thompson : “plum-pudding”model of the atom
1911 Ernest Rutherford: “planetary” model of the atom
It took 10 years to realize the muon wasn’t Yukawa’s pion.
At the beginning, the “quark” model was not accepted widely.
