The life and work of a great scientist. The mathematics and figures are there (reproduced here in their full original beauty) but it is also a life to be read, by anyone, for its delightful enjoy character - enjoy the vivid account of his teaching practices for example! - delightfully told by one of Lord Kelvin's admirers: "His statement, which has been so often quoted, that after fifty-five years of constant study he knew little more of electricity and magnetism than he did at the beginning of his career... was, like Newton's famous declaration, an indication of his sense of the vastness of the ocean of truth and the manifoldness of the treasures which still lie within its "deep unfathomed caves." He had faith that in the end all that appeared dark and perplexing would stand forth in fulness of light".
