JAMES CLERK MAXWELL
Maxwell's equations demonstrated that electricty, magtetism and light are manifestaions of the same phenomenon, the electro magnetic field.
He also developed the Maxwell distribution, a statistical means to describe aspects of the kinetic theory of gases.
discoveries changed the world of physics forever and made possible
future leaps in scientific progress in fields such as relativity
and quantum mechanics. Maxwell even created the first true colour
His massive contribution to the world of physics influenced 20th Century scientists such as Albert Einstien who kept a photograph of Maxwell and Newton on his study wall.
