Contribution to the Development of the Atomic Concept
James Clerk Maxwell's principal contribution to the atomic concept had to do with his theory of electromagnetism.  His mathematical laws of electrodynamics, formulated between 1864 and 1873, describe the phenomenon of electromagnetic radiation and build directly upon the earlier speculations of Michael Faraday.  Maxwell's laws predict that any system in which a charged particle orbits about an oppositely charged particle (for example, an electron orbiting about the nucleus) should emit light at a frequency related to the radius of the orbiting particle.  In the case of an orbiting electron, his theory predicted that the electron would spiral into the nucleus in a very small fraction of a second.  His laws were well established at the time that Rutherford proposed the nuclear atom and the orbiting electron was a model that lasted only for a few years before it was replaced by the stationary states of Neils Bohr and, ultimately, by the quantum mechanical atom.  Maxwell also co-formulated (along with Ludwig Boltzmann who worked independently) the kinetic theory of gases.

Some Scientific/Historical Traveling Sites
Maxwell birthplace. Click here to see the sign outside the door of the house(1,2) 14 India Street, Edinburgh, Scotland
Glenlair, the Maxwell Estate (destroyed by fire in 1929).  Maxwell wrote his Treatise on Electricity and Magnetism here between 1868 and 1871(1,2) About five miles from the village of Parton
Church where the Maxwell's worshipped;  Maxwell, his father, mother, and his wife Katherine are buried in the ruins of the old chapel (the "Old Kirk") A plaque in the front of the church honors Maxwell and calls him "a good man, full of humour and wisdom. *(1,2) The village of Parton, Scotland
A church built "through the influence and exertion of Maxwell's father" (1); contains a stained glass window installed to honor James Clerk Maxwell * (1,2) The village of Corsock, Scotland
