Introduction to elementary particles 1

Elementary particle physics is a discipline that aims to understand the origin of matter at the most fundamental level. An outline of elementary particle physics is presented as plainly as possible in the three-part tutorial. In the first part, the most fundamental particles called quarks and leptons are introduced. Quarks consist protons, neutrons and mesons, which Dr. Hideki Yukawa had predicted, while neutrinos and electrons are called leptons along with muons, which were discovered by Dr. Yoshio Nishina.
