Frank S. Levin, PhD, is an Emeritus Professor from Brown University, where he taught both undergraduate and graduate physics courses and carried out internationally recognized research. Soon after retiring he began teaching science courses for persons with neither a math nor a science background. Among these courses have been ones on global warming, an outgrowth of which is the current volume. Other courses have been on cosmology and on quantum ideas and phenomena, each of which has been the basis for popular science books: Calibrating the Cosmos (2007) and Surfing the Quantum World (2017). He is also the author of the undergraduate text An Introduction to Quantum Theory (2002).
