Cohen English | PDF | 1989 | 159 Pages | ISBN : 1461388430 | 6.7 MB Historically, nonclassical physics developed in three stages. First came a collection of ad hoc assumptions and then a cookbook of equations known as "quantum mechanics". The equations and their philosophical underpinnings were then collected into a model based on the mathematics of Hilbert space. From the Hilbert space model came the abstaction of "quantum logics". This book explores all three stages, but not in historical order. Instead, in an effort to illustrate how physics and abstract mathematics influence each other we hop back and forth between a purely mathematical development of Hilbert space, and a physically motivated definition of a logic, partially linking the two throughout, and then bringing them together at the deepest level in the last two chapters. This book should be accessible to undergraduate and beginning graduate students in both mathematics and physics. The only strict prerequisites are calculus and linear algebra, but the level of mathematical sophistication assumes at least one or two intermediate courses, for example in mathematical analysis or advanced calculus. No background in physics is assumed.  Free Download An Electronics Engineer's Notebook: Projects, Simulations, Programming... and Some Riddles English | 2025 | ISBN: 3031952278 | 356 Pages | PDF EPUB (True) | 148 MB This book features a compilation of applicable and insightful engineering notes extracted from the author's multi-decade career in industry and academia. The book includes a plethora of modern engineering tools, including simulators and platforms like Matlab and LabVIEWTM that have been utilized to support the topics. The book is organized into four parts: Riddles, Simulations, Projects, and Math. The Riddles include puzzling issues encountered in the basic concepts and their various solutions. The Simulations section presents examples of challenging simulations, such as an ECG telemetry system, a software timer IC, and a random number generator. The section also addresses the weak points of simulators that must be considered. The Projects part comprises hardware and software projects from real life, including a DTMF pager and a barcode reader. The Math part aims to underline the importance of mathematics in engineering. For example, complex numbers are employed to show how to generate rotating magnetic fields and explain the backward-rotating wheels of carts in movies. A project exploiting vector algebra calculates the distance and heading between two points on the earth. The part is concluded with a Sudoku generator. This toolbox of solutions is intended for researchers, academics, students and professionals in electrical engineering.

Free Download Steven Stern, "Airless Worlds and the Restoration of Psychic Breathing " English | ISBN: 1032952903 | 2025 | 164 pages | EPUB | 447 KB This book focuses on the recognition and psychoanalytic treatment of a debilitating form of early relational trauma poignantly described by Steven Stern as airless world syndrome.  Free Download Christopher Shores - Air Aces Presidio Press | 1983 | ISBN: 0891411666 | English | 200 pages | PDF | 182.57 MB An Ace is generally accepted as a fighter pilot who has shot down five or more enemy aircraft. Since the beginning of air fighting each war and campaign has produced its air aces. This book not only describes the fighting careers of the famous fighter pilots, but places their achievements in the context of the conditions under which they fought. For example, the 352 victories of the Luftwaffe ace Erich Hartmann could only have been gained over the Russian Front in World War II. This exhaustively researched book contains a wealth of information on the air aces of modern warfare. Tables give statistics on all wars since 1914, including lesser known ones like the Russian Civil War and the Indo-Pakistan conflicts. Individual biographies are included on the greatest aces - Lufberry, Gabreski, Galland and Bong to name but a few. More than 250 color and B&W photographs.  Free Download Iakovos Vasiliou, "Aiming at Virtue in Plato" English | ISBN: 0521862965 | 2008 | 322 pages | PDF | 1369 KB This study of Plato's ethics focuses on the concept of virtue. Based on detailed readings of the most prominent Platonic dialogues on virtue, it argues that there is a central yet previously unnoticed conceptual distinction in Plato between the idea of virtue as the supreme aim of one's actions and the determination of which action-tokens or -types are virtuous. Appreciating the 'aiming/determining distinction' provides detailed and mutually consistent readings of the most well-known Platonic dialogues on virtue as well as original interpretations of central Platonic questions. Unlike most examinations of Plato's ethics, this study does not take as its centrepiece the 'eudaimonist framework', which focuses on the relationship between virtue and happiness. Instead, it argues that the dialogues themselves begin with the idea of the supremacy of virtue, examine how that claim can be defended, and address how to determine what constitutes the virtuous action.  Free Download Anuja Khanna, "Aftermath of 1984 Anti-Sikh Violence " English | ISBN: 1032396555 | 2025 | 152 pages | PDF | 2 MB This book explores the inheritance of trauma, distress, and healing from one generation of survivors of the 1984 anti-Sikh violence to the next. It looks at this dyadic relationship and the post-violence context that is marked by their experience of injustice. |
