James Clerk Maxwell was a theoretical physicist who formulated the mathematical theory of oscillating electric and magnetic fields, now known as Maxwell’s equations. These equations are fundamental to physics and are studied by every graduate-level student; mastering them is essential for earning a PhD in many areas of physics.
There is a famous humorous line inspired by their elegance:
“In the beginning, God said, ‘The four-dimensional divergence of an antisymmetric second-rank tensor is zero.’ And there was light.”
