The Strange Story of the Quantum

Completely non-mathematical, yet wholly faithful to the basic concepts of quantum mechanics, this book tells the fascinating story of the most thoroughgoing revolution in physics since Newton. In the first year of the twentieth century, a professor of theoretical physics in Berlin, Max Planck, suggested that light was not absorbed smoothly, but rather in small bundles or "quanta." Five years later, a Swiss patent clerk, Albert Einstein, proposed that the radiation itself must exist as quanta. Thus was born a new age in physics — the age of the quantum — in which some of the most basic assumptions of classical physics were swept away, and a magnificent new theoretical structure created.
