Ken A. Dill is Professor of Pharmaceutical Chemistry and Biophysics at the University of California, San Francisco. He received his undergraduate training at MIT, his PhD from the University of California, San Diego, and did postdoctoral work at Stanford. A leading researcher in biopolymer statistical mechanics and protein folding, he has been the President of the Biophysical Society and received the Hans Neurath Award from the Protein Society in 1998.

Sarina Bromberg received her BFA at the Cooper Union for the Advancement of Science and Art, her PhD in molecular biophysics from Wesleyan University, and her postdoctoral training at the University of California, San Francisco. She writes, edits and illustrates scientific textbooks.

"Molecular Driving Forces, Second Edition" is an introductory statistical thermodynamics text that describes the principles and forces that drive chemical and biological processes. The second edition includes an additional chapter on thermodynamics and two new chapters: 'Microscopic Dynamics' which explores single molecule experiments, and 'Bio and Nano Machines' which describes the workings of biological molecules including proteins and DNA. New examples and practical applications are integrated throughout the revised and updated text, exploring topics in biology, environmental and energy science, and nanotechnology. It also includes new end-of-chapter problems, and purely mathematical topics are now in appendices. Written in a clear and reader-friendly style, the book provides an excellent introduction to the subject for novices while remaining a valuable resource for experts.
