He worked in the mid-nineteenth century in Scotland and England. By uncovering that they all were manifestations of the electromagnetic field, his electromagnetic theory was a huge breakthrough in science. Microwaves were first predicted by James Clerk Maxwell in 1864 by the use of his equations. James Clerk Maxwell, (born June 13, 1831, Edinburgh, Scotland—died November 5, 1879, Cambridge, Cambridgeshire, England), Scottish physicist best known for his formulation of electromagnetic theory. Soon after his birth the family moved to a countryside estate about 15 miles from the town of Dumfries. MAXWELL DISCOVERS LIGHT IS ELECTROMAGNETIC WAVES James Clerk Maxwell was a Scottish scientist. Maxwell went on to discover that colour photographs could be formed using red, green, and blue filters. Maxwell’s Equations provide a complete description of electromagnetic phenomena and underpin all modern information and communication technologies. His most famous achievement was predicting that light was an electromagnetic wave. The Scotsman James Clerk Maxwell (1831–1879) is regarded as the greatest theoretical physicist of the 19th century. James Clerk Maxwell (1831 - 1879) was a physicist born June 13,1831, in Edinburgh, Scotland, where his parents lived in an affluent neighborhood. Later during 1888 Heinrich Hertz proved the existence of microwaves by building a device … James Clerk Maxwell was a physicist and mathematician by profession. James Clerk Maxwell, (born June 13, 1831, Edinburgh, Scotland—died November 5, 1879, Cambridge, Cambridgeshire, England), Scottish physicist best known for his formulation of electromagnetic theory.Maxwell's ideas also ushered in the other major innovation of … He worked in the mid-nineteenth century in Scotland and England. James Clerk Maxwell (1831-1879) was one of the greatest scientists who have ever lived. Maxwell James Clerk Maxwell (13 June 1831 – 5 November 1879) James was born in Edinburgh, Scotland in 1831. Three photos were taken, each time with a different colour filter over the lens. Maxwell helped move physics away from the classical, mechanical world view of Newton towards the quantum, probabilistic view that we rely on today – a view Albert Einstein was never happy with, claiming famously that ‘God does not play dice with the Universe.’ An Early Demise.
