Extract from a letter from Michael Faraday to J. Clerk MaxwellRoyal Institution, 13 November 1857There is one thing I would be glad to ask you. When a mathematician engagedin investigating physical actions and results has arrived at his own conclusions,may they not be expressed in common language as fully, clearly, and definitelyas in mathematical formulae? If so, would it not be a great boon to such as we toexpress them so – translating them out of their hieroglyphics that we also mightwork upon them by experiment? I think it must be so, because I have found thatyou could convey to me a perfectly clear idea of your conclusions, which, thoughthey may give me no full understanding of the steps of your process, gave methe results neither above nor below the truth, and so clear in character that I canthink and work from them.If this is possible, would it not be a good thing if mathematicians, writing on thesesubjects, were to give us their results in this popular useful working state as wellas in that which is their own and proper to them?Extract from “On Giants’ Shoulders” by Melvyn BraggHodder & Stoughton 19982
