Mechanics, Molecular Physics, and Heat: A Twelve Weeks' College Course is a textbook written by Robert Andrews Millikan and published in 1903. The book is designed as a comprehensive course on mechanics, molecular physics, and heat for college students, covering topics such as kinematics, dynamics, thermodynamics, and statistical mechanics. The book is divided into twelve chapters, each of which focuses on a specific aspect of the subject matter. The first few chapters cover the basic principles of mechanics, including motion, force, work, energy, and momentum. The following chapters delve into molecular physics, discussing the behavior of gases, liquids, and solids, as well as the properties of atoms and molecules. The final chapters of the book explore the principles of heat and thermodynamics, including the laws of thermodynamics, the behavior of heat engines, and the concepts of entropy and free energy. Throughout the book, Millikan provides numerous examples and problems for students to work through, helping them to better understand the material and develop their problem-solving skills. Overall, Mechanics, Molecular Physics, and Heat: A Twelve Weeks' College Course is a comprehensive and detailed textbook that provides a solid foundation in the principles of mechanics, molecular physics, and heat. It is an excellent resource for college students studying physics or related subjects, as well as for anyone interested in gaining a deeper understanding of these fundamental concepts.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
