These five articles explain what bosons and fermions are, and how the concept of these categories of particles is applied in physics. The first article explains how supersymmetry relates bosons and fermions to one another. Supersymmetry is a very important topic in the contemporary particle physics community. First theorized in the early 1970s, many expect that it will soon be supported by experiments at the LHC in Geneva, Switzerland. The second article can be read independently of the first. The third, fourth, and fifth articles can be read independently of one another, but you may have to read the second article in order to understand them. The third article explains how the idea of color charge of quarks was introduced to reconcile the theory with Pauli's exclusion principle, and goes on to explain some interesting characteristics of the strong force. The fourth article explains the microscopic statistical properties of identical particles which may seem bizarre to macroscopic human beings. The fifth article supplies another derivation of Pauli's exclusion principle via an approach alternative to that taken in the second article.
