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.

Freud's excellent lectures introducing the key pillars of psychoanalytic practice and theory are presented here complete in hardcover. Delivered between 1915 and 1917, the lectures detail theories pioneered by Freud. Delivered in the later part of his career, these lectures are a retrospective summary of the ideas which revolutionized psychology in the early 20th century. It is here that the fully-formed ideas are expressed clearly, with the added benefit of experiences Freud had in employing his methods to treat sufferers of mental illness and neuroses. The translation of the lectures to English was accomplished by Freud's contemporary G. Stanley Hall. Since appearing in 1920, this rendition of the lectures has been praised for accurately relaying the concepts, theory and practices behind Freudian psychoanalysis. This edition also contains an introductory preface by Hall, who explains the intellectual context and rival theories present in the-then fledgling scientific discipline of psychology.

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.
