ellipse by defining the locus of a point where the sum of m times the distance<br />
from one fixed point plus n times the distance from a second fixed point is<br />
constant. (m = n = 1 corresponds to an ellipse.) He also defined curves where<br />
there were more than two foci. This first paper, On the description of oval<br />
curves, and those having a plurality of foci, was read to the Royal Society of<br />
Edinburgh in 1846. At age 16, he entered the University of Edinburgh and,<br />
although he could have attended Cambridge after his first term, he instead<br />
completed the full course of undergraduate studies at Edinburgh. At age 18,<br />
he contributed two papers to the Transactions of the Royal Society of Edinburgh.<br />
In 1850, he moved to Cambridge University, first to Peterhouse and<br />
then to Trinity where he felt his chances for a fellowship were greater. He<br />
was elected to the secret Society of Apostles, was Second Wrangler and tied<br />
for Smith’s Prizeman. He obtained his fellowship and graduated with a degree<br />
in Mathematics in 1854. Immediately after taking his degree, he read<br />
to the Cambridge Philosophical Society the purely mathematical memoir On<br />
the transformation of surfaces by bending. In 1855, he presented Experiments<br />
on colour to the Royal Society of Edinburgh where he laid out the principles<br />
of colour combination based upon his observations of colored spinning tops<br />
(Maxwell discs). (Application 14 concerns the related Maxwell Color Triangle.)<br />
In 1855 and 1856, he read his two part paper On Faraday’s lines of force<br />
to the Cambridge Philosophical Society where he showed that a few simple<br />
mathematical equations could express the behavior of electric and magnetic<br />
fields and their interaction. In 1856, Maxwell took up an appointment at Marishcal<br />
College in Aberdeen. He spent the next two years working on the nature<br />
of Saturn’s rings and, in 1859, he was awarded the Adams Prize of St. John’s<br />
College, Cambridge for his paper On the stability of Saturn’s rings where he<br />
showed that stability could only be achieved if the rings consisted of numerous<br />
small solid particles, an explanation finally confirmed by the Voyager spacecrafts<br />
in the 1980’s! In 1860, he was appointed to the vacant chair of Natural<br />
Philosophy at King’s College in London. He performed his most important experimental<br />
work during the six years that he spent there. He was awarded the<br />
Royal Society’s Rumford medal in 1860 for his work on color which included<br />
the world’s first color photograph, and was elected to the Society in 1861. He<br />
also developed his ideas on the viscosity of gases (Maxwell-Boltzmann kinetic<br />
theory of gases), and proposed the basics of dimensional analysis. This time<br />
is especially known for the advances he made in electromagnetism: electromagnetic<br />
induction, displacement current and the identification of light as an<br />
electromagnetic phenomenon. In 1865, he left King’s College and returned to<br />
his Scottish estate of Glenlair until 1871 when he became the first Cavendish<br />
Professor of Physics at Cambridge. He designed the Cavendish laboratory<br />
and helped set it up. The four partial differential equations now known as<br />
Maxwell’s equations first appeared in fully developed form in A Treatise on
