Ojeh, Earl Wright II English | February 29, 2024 | ISBN: 0367470934 | 150 pages | PDF | 1.41 Mb An Introduction to W. E. B. Du Bois examines the historical contributions to social science and the continuing relevance of the work of W. E. B. Du Bois in an accessible manner. The first volume of its kind, it places the theories of Du Bois in context, showing how the socio‑racial environment in which he grew up and came of age influenced the development of his thought. In addition to covering well‑known concepts such as double consciousness, the veil, and religious fatalism, the authors discuss Du Bois' uncoined theories emanating from the Atlanta University Studies, as well as his contributions to the development of Black sociology and research methodology. A groundbreaking contextualization and summary of the importance of Du Bois' work to sociology and sociological theory, this book constitutes a much‑needed resource for scholars and students seeking to understand this scholar's significance to the social sciences beyond the elementary level.

Free Download An Introduction to Hilbert Space and Quantum Logic by David W. 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.
