Changes

From the way in which changes in a [[magnetic field]] produce electric fields, and the way in which changes in electric fields produced magnetic fields, Maxwell deduced a set of equations that describe them, [[Maxwell's Equations]], in 1861.  The equations predicted the possibility of electromagnetic waves. Other scientists looked for and detected these waves, which led both to the development of radio communication and to the discovery that light is a kind of [[electromagnetic wave]].

He also invented [[Maxwell's demon]] as a demonstration of the impossibility of [[perpetual motion]].

He also proposed a thought experiment that became known as [[Maxwell's demon]] which was designed as a challenge to the [[Second Law of Thermodynamics]].
