Describing Motion: The Physical World provides the quantitative description of a variety of physically important motions. Starting with simple examples of motion along a line, the book introduces key concepts, such as position, velocity, and acceleration, using the fundamental rules of differential calculus. Topics include the free-fall motion of micro-gravity test vehicles, the trajectories of long-jumpers, and the orbital motion of satellites and space probes. The book also covers several essential mathematical tools.

Quantum Physics of Matter explores the way in which quantum physics determines the properties of materials. The quantum physics of solids, for example, dictates whether they are good insulators, conductors, semiconductors, or even superconductors. At a deeper level, it explores how the quantum physics of nuclei and elementary particles determines the stability of matter and hence the range of substances that came into existence through the big bang and the evolution of stars.
