3. Maxwell's Equations (Wikipedia.org)
"In electromagnetism, Maxwell's equations are a set of four equations that were first presented as a distinct group in 1884 by Oliver Heaviside in conjunction with Willard Gibbs. These equations had appeared throughout James Clerk Maxwell's 1861 paper entitled On Physical Lines of Force."

"Those equations describe the interrelationship between electric field, magnetic field, electric charge, and electric current. Although Maxwell himself was the originator of only one of these equations (by virtue of modifying an already existing equation), he derived them all again independently in conjunction with his molecular vortex model of Faraday's 'lines of force'." 02-08

4. Voltage (Georgia State University)
"Voltage is electric potential energy per unit charge, measured in joules per coulomb ( = volts)." 02-08

Papers
1. -Graphene Is the World's Strongest Material (CNET.com)
"Besides being the hardest substance in the world -- 300 times stronger than steel -- graphene has all sorts of other noteworthy qualities. It is also the thinnest object ever obtained by man -- measuring just one atom thick -- and the lightest. It is made of a 2D crystal and looks a bit like scotch tape, only infinitely thinner. Graphene is also transparent, bendable, and a far better conductor than copper." 01-13

2. Electricity (Wikipedia.org)
"Electricity is a property of certain subatomic particles, such as electrons and protons, that gives rise to attractive and repulsive forces between them. It is one of the four fundamental forces of nature, and is a conserved property of matter that can be quantified." 10-04
