Symmetry in Physics

Symmetry is quite beautiful in its applications. From photographs to paintings to music, a sense of symmetry gives a sense of balance and therefore is comfortable to look at. In the same way, symmetry in physics also yields beautiful results. According to Feynman, symmetry is when “if there is something we can do to it so that after we have done it, it looks the same as it did before”. Indeed, symmetry has multiple deep applications in theoretical physics. In Electrodynamics, for example, symmetry helps to make calculations easier, removing the need for complex integrals. In quantum mechanics, the applications of symmetry are massive.

And of course, who could forget one of the more recent and memorable applications of symmetry:
