NOWhich form of the equations do you like best? ⚡
Maxwell's equations describe the behaviour of electric and magnetic fields. They were originally written down by James Clerk Maxwell in 1861 as a set of 20 partial differential equations, but reformulated by Oliver Heaviside using vector calculus into four equations. The potential formulation reduced the number of equations to two, but they were still unwieldy. After Albert Einstein's discovery of special relativity in 1905, Hermann Minkowski quickly realized that matrices could be used to describe the electromagnetic field strength F, leading to the four-vector notation. Finally, Élie Cartan, using the language of differential geometry and differential forms, wrote the most compact form in 1924.
