Basil Mahon wrote a book about Maxwell.
It's a fantastic book on the life of the great Maxwell, that thanks to his discoveries, changed radically the approach to the physics and our's everyday life.
I found it pleasant to read and that passes emotions, the same that James wanted to arouse in his students.
It's really interesting to see the reasoning under the explaining of his theories. Even if it's technically and physically accessible, to fully understand it it's necessary a minimum predisposition to the scientific reasoning and, maybe, some math.
I suggest and i wish to everyone to read it.
Buy it from Amazon.com ! (Even from Amazon.it or Amazon.co.uk)
