Classical Mechanics teaches readers how to solve physics problems; in other words, how to put math and physics together to obtain a numerical or algebraic result and then interpret these results physically. These skills are important and will be needed in more advanced science and engineering courses. However, more important than developing problem-solving skills and physical-interpretation skills, the main purpose of this multi-volume series is to survey the basic concepts of classical mechanics and to provide the reader with a solid understanding of the foundational content knowledge of classical mechanics. Classical Mechanics: Conservation Laws and Rotational Motion covers the conservation of energy and the conservation of momentum, which are crucial concepts in any physics course. It also introduces the concepts of center-of-mass and rotational motion.

Ophthalmologist Nathaniel L. MacBride discusses the various maladies of the eye - first published in 1897, this book offers insight into the history of ophthalmology and eye medicine. Beginning with an anatomical discussion of the cornea, iris and conjunctiva, the author goes on to discuss the various ailments afflicting the eye, such as glaucoma and conjunctivitis. The second part of the book details the physics of eyesight, and how one can discern disturbances to the eye's function, such as the appearance of cataracts. As this book dates to the late 19th century, the treatments described have long been obsoleted. The application of cocaine solution upon the eye for instance has no place in modern ophthalmology. The surgical techniques of the time were conducted manually and with metallic instruments; such methods are outdated in the modern day.
