This paper describes a brief history of symmetry and symmetry breaking in physics, describes the concepts of symmetry and symmetry breaking both spontaneous and explicit, and explores spontaneous symmetry breaking in quantum field theory, giving examples accompanied by Feynman Diagrams and simplified Lagrangian equations Finally, some examples of spontaneous symmetry breThis paper describes a brief history of symmetry and symmetry breaking in physics, describes the concepts of symmetry and symmetry breaking both spontaneous and explicit, and explores spontaneous symmetry breaking in quantum field theory, giving examples accompanied by Feynman Diagrams and simplified Lagrangian equations Finally, some examples of spontaneous symmetry breaking are given for classical systems.
