Consciousness, Physics, and the Holographic ParadigmEssays by A.T. Williams Part I: Sneaking Up On EinsteinAs far as the laws of mathematics refer to reality, they are not certain,
Chapter 4Section 2: Faraday, Thomson, and MaxwellClerk Maxwell (pronounced "Clark") graduated in 1854 from Trinity College, Cambridge, with a Bachelor of Arts degree in mathematics. His close relationships with previous Cambridge graduates included William Thomson (1824-1907) (later Lord Kelvin), Professor of Natural Philosophy at the University of Glasgow, and George G. Stokes (1819-1903), Lucasian Professor of Mathematics at Cambridge. Thomson and Stokes were among the top, if not the top, mathematical theoreticians in England at that time. In a letter dated February 20, 1854, Maxwell asked Thomson for advice in studying the new science of electricity: If [one] wished to read Ampère Faraday &c how should they be arranged, and at what stage & in what order might he read your articles in the Cambridge Journal? William Thomson's education and career had been enhanced and facilitated by his father, James Thomson, who was appointed to the Chair of Mathematics at the University of Glasgow in 1832. Thomson graduated from Cambridge in 1845 at age 21, then traveled to Paris and studied French scientific and mathematical methods. In Paris, Joseph Liouville (1809-1882) encouraged Thomson's professional interest in Faraday, whom Thomson knew and interacted with in London, by suggesting that the reconciliation of Faraday's electrostatic experimental results and the views of the French mathematicians, Ampère, Coulomb, Poisson, etc., could be a fertile field of mathematical endeavor. Intrigued by Liouville's suggestion Thomson wrote several papers over the next few years based on Faraday's experimental results, including:
After receiving Maxwell's request for guidance, Thomson shared with him the challenge presented by interpreting Faraday's experimental results using mathematical formalism. Maxwell was also intrigued and began his research by reading Thomson's papers. Maxwell's first published paper based on Faraday's work attempted "to shew how, by a strict application of the ideas and methods of Faraday, the connexion of the very different orders of phenomena which he has discovered may be clearly placed before the mathematical mind."9 The resulting paper, On Faraday's Lines of Force, was read in two parts to the Royal Society, London, on December 10, 1855, and February 11, 1856.10 The paper, based on fanciful ad hoc analogies rather than Faraday's experimental results, can be seen as the logical extension of Thomson's earlier work. Six years later Maxwell published a second paper, On Physical Lines of Force, in which he again employed Thomson's method of creating fanciful ad hoc analogies while seeking a mechanical rationale for magnetic lines of force, was published in 1861-1862. He wrote:11 I propose now to examine magnetic phenomena from a mechanical point of view, and to determine what tensions in, or motions of, a medium are capable of producing the mechanical phenomena observed. If, by the same hypothesis, we can connect the phenomena of magnetic attraction with electromagnetic phenomena and with those of induced currents, we shall have found a theory which, if not true, can only be proved to be erroneous by experiments which will greatly enlarge our knowledge of this part of physics.12 Maxwell's definitive paper on electricity and magnetism, A Dynamical Theory of the Electromagnetic Field, was published in 1864.13 His work had progressed to the point of proposing a bona fide physical theory which focused on developing the mathematical formalism of Faraday's physically real experimental results as opposed to the fanciful ad hoc analogies and particles acting at a distance employed in the first two papers. In the introductory paragraphs he explained: The theory I propose may therefore be called a theory of the Electromagnetic Field, because it has to do with the space in the neighbourhood of the electric or magnetic bodies, and it may be called a Dynamical Theory, because it assumes that in that space there is matter in motion, by which the observed electromagnetic phenomena are produced. (Maxwell's emphasis)14 In the 1864 paper Maxwell also acknowledges Faraday's priority with regard to the transverse propagation of electric and magnetic fields:
Far removed from the actual, historical events as we enter the 21st century CE, it is of some interest to note that Faraday's paper, Thoughts on Ray Vibrations, was published 18 years before Maxwell published his Dynamical Theory of the Electromagnetic Field.
