One of the most imaginative mathematicians of the nineteenth century, Sir William Rowan Hamilton (1805-1865) changed the course of modern algebra with his discovery of quaternions in 1843. Although Hamilton's work was largely theoretical, his ideas came to have invaluable practical applications with the advent of quantum mechanics in the twentieth century. In this acclaimed biography, Thomas L. Hankins brings together the many aspects of Hamilton's life and work--from his significant contributions to mathematics, optics, and mechanics to his passion for metaphysics, poetry, and...

Thomas Hankins and Robert Silverman investigate an array of instruments from the seventeenth through the nineteenth century that seem at first to be marginal to science--magnetic clocks that were said to operate by the movements of sunflower seeds, magic lanterns, ocular harpsichords (machines that played different colored lights in harmonious mixtures), Aeolian harps (a form of wind chime), and other instruments of "natural magic" designed to produce wondrous effects. By looking at these and the first recording instruments, the stereoscope, and speaking machines, the authors show that...
