Contributions Maxwell's Equations  Image From: https://physicsabout.com/maxwells-equations/     Maxwell's equations are undoubtedly one of his greatest contributions as they provide the basis for the modern study of electricity and magnetism. They connect the two concepts and can provide a number of important conclusions. One of the more interesting of these conclusions is the speed of light. Using his equations, Maxwell set up an experiment to calculate the speed of light. His results were remarkable accurate for the time period. Dimensional Analysis     This one does not require much explanation. Maxwell was the first to utilize the technique of dimensional analysis during his time at King's College. It allowed for the comparison of different physical quantities and is a commonly used today. Color Photographs     Maxwell's study on the way the human eye processes images lead directly to the first color photograph. Maxwell noted that the human eye sees in only three colors: red, green, and blue. He suggested that by taking a regular black and white photo through filters of those colors, a realistic color image could be created.

He showed that temperature is a result of the movement of molecules, and that gas molecules move at different speeds. His research would later be generalized by Ludwig Boltzmann into what is now know as a Maxwell - Boltzmann Distribution.
