Maxwell's formulation of his equations of electromagnetism is one of the greatest feats of human intellect.

Engineering achievements

Maxwell's equations of electromagnetism are regarded as a main foundation of modern electrical/electronic engineering. They have underpinned a wide range of engineering technologies across the electromagnetic spectrum inlcuding X-Ray, radio, television, microwaves and mobile phones. He did important work on thermodynamics. He was the first to develop a theory of servomechanics (cybernetics). In structural mechanics he developed: photoelasticity for stress measurement; reciprocal diagrams for analysis of statically determinate trusses; the flexibility method for analysing indeterminate trusses.
He devised the plastic failure criterion for materials now referred to as the 'von Mises criterion' well ahead of von Mises. He did important work in optics and colour vision. He did important work in relation to viscoelasticity and relaxation processes in glass. He achieved all of this despite only living to the age of 48.

His Legacy

In his work on gas dynamics Maxwell introduced the treatment of movement of molecules on a statistical basis. This is one of the cornerstones of quantum theory. It is said that all of modern physics leads back to Maxwell. He was not a towering presence in his time. Even today, his contribution is still not as well recognised as it deserves to be, except amongst physicists. He was, undoubtedly, the greatest Scottish scientific genius, the greatest physicist worldwide in the nineteenth century and in the top three in the past 2,000 years, standing shoulder to shoulder with Newton and Einstein in his contributions. Einstein had a framed photograph of Clerk Maxwell in his study, alongside Newton and Faraday. Einstein himself described Maxwell's work as the "most profound and the most fruitful that physics has experienced since the time of Newton" and acknowledged that his Theory of Relativity would not have been possible without Maxwell's work on electromagnetism. In his relatively short career as a physicist the span of topics that Maxwell addressed is remarkable. In each case his investigations turned into scientific gold.

Nobel prizewinning physicist Richard P Feynman said "From a long view of the history of mankind - seen from, say, ten thousand years from now - there can be little doubt that the most significant event of the 19th century will be judged as Maxwell's discovery of the laws of electrodynamics"
