It is practically a rite of passage for physics majors. We study Maxwells equations – the illuminating set of relationships that reveal the nature of light; we marvel at the power and grace of this compact quartet, and can't resist a chuckle when – inevitably – we come across the t-shirt that says “God said [Maxwell's Equations] And there was light.” Something about that sticks. We remember the t-shirt years later, even if we can't write down the equations anymore.
But, even though James Clerk Maxwell could boast several outstanding accomplishments – including taking the first ever color photograph, and unleashing a fictional demon that outwits entropy – for far too many of us, our association with this brilliant scientist begins and ends with the famous equations that govern electromagnetic radiation.
There is no cult of genius surrounding Maxwell. Unlike Einstein, Feynman or more recently, Hawking, Maxwell has no groupies; his quotes don't adorn bumper stickers, physics students don't own collections of his lectures or writing, and I don't know of anyone (save Einstein) who put up a poster of Maxwell in their workspace.
Like thousands of other physics students who went to college, studied Maxwell's equations, and bought the t-shirt, I felt no real bond with the man until some years ago, when a writing project (to which I shall forever remain indebted) led me to find out more about him.
I read Maxwell's writings as part of my research, and it was love at first letter. I was completely enchanted by the mind revealed in, and between, the lines; it was an investigative, creative, whimsical creature, with scintillating wit and lyrical expression. Over the months, as I read more, my initial intellectual infatuation developed into a deep fondness and a genuine respect. I found the flow of Maxwell's logic and the dance of his ideas simply beautiful. I read and re-read his words for the pleasure of having them stream through my mind, but also in the hope that if they performed his choreography enough times, my thoughts might learn to move that way on their own.
Casting around today for a piece of writing that might serve as an introduction to Maxwell, I settled upon his 1870 address to the members of the British Association (whom Maxwell teasingly referred to as the British ‘Asses') about scientific metaphor. This is not an idea that is articulated very often, especially not this clearly, but it is precisely the sort of overarching theme that I think should be emphasized in physics classrooms everywhere.
