Maxwell's Equations
Supporting his theorems, Maxwell's Equations—speaking to the scholar's aptitude in using math to articulate scientific occurrences—were found in the paper "Dynamical theory of the electromagnetic field," presented to the Royal Society of London in 1864 and published the following year. In 1873 he published the book A Treatise on Electricity and Magnetism, which further expounded on his research.

Maxwell's other scientific contributions included producing the first color photograph, taken in 1861, and creating structural engineering calculations for bridge maintenance. He earned an array of awards over the course of his career, including the Rumford Medal, Keith Prize and Hopkins Prize, in addition to receiving membership in groups like the Royal Academy of Sciences of Amsterdam. Other publications included Theory of Heat (1871) and Matter and Motion (1877).
