Although various principles of electricity have been known for centuries, it is only since the formulation of key mathematical models that scientists and engineers have been able to fully harness this power.
Maxwell’s equations: James Clerk Maxwell (Scottish, 1831 – 1879) developed a series of equations that described the fundamental laws of electricity and magnetism. His impact on the study of electromagnetics has been compared to Newton’s impact on mechanics. Maxwell’s rigorous application of mathematics became the new model for scientific communication.
