This correspondence became therefore the cornerstone of

Maxwell's theory, which sees in light nothing else than electromagnetic oscillations, a theory that has found strong support at Leiden University.

Maxwell's theory predicted electromagnetic waves, and established the relationship between optics and electronics.

The book begins with

Maxwell's theory of electromagnetism, and the ultimately profound realization that light is an electromagnetic wave and an electromagnetic wave is light.

Fifth, from the viewpoint of reductionism,

Maxwell's theory of electromagnetic fields can only be regarded as a phenomenological theory.

Students are expected to have the usual mathematics at the calculus level, some familiarity with matrices, and the physics of mechanics and electromagnetism including differential equations of

Maxwell's theory.
