#1 NEW YORK TIMES BESTSELLER A landmark volume in science writing by one of the great minds of our time, Stephen Hawking’s book explores such profound questions as: How did the universe begin—and what made its start possible? Does time always flow forward? Is the universe unending—or are there boundaries? Are there other dimensions in space? What will happen when it all ends? Told in language we all can understand, A Brief History of Time plunges into the exotic realms of black holes and quarks, of antimatter and “arrows of time,” of the big bang and a bigger God—where the possibilities are wondrous and unexpected. With exciting images and profound imagination, Stephen Hawking brings us closer to the ultimate secrets at the very heart of creation.
Was there a beginning of time? Could time run backwards? Is the universe infinite or does it have boundaries? These are just some of the questions considered in an internationally acclaimed masterpiece by one of the world's greatest thinkers. It begins by reviewing the great theories of the cosmos from Newton to Einstein, before delving into the secrets which still lie at the heart of space and time, from the Big Bang to black holes, via spiral galaxies and strong theory. To this day A Brief History of Time remains a staple of the scientific canon, and its succinct and clear language continues to introduce millions to the universe and its wonders.

Hawking on the Big Bang and Black Holes by Stephen Hawking Pdf
Stephen Hawking, the Lucasian Professor of Mathematics at Cambridge University, has made important theoretical contributions to gravitational theory and has played a major role in the development of cosmology and black hole physics. Hawking's early work, partly in collaboration with Roger Penrose, showed the significance of spacetime singularities for the big bang and black holes. His later work has been concerned with a deeper understanding of these two issues. The work required extensive use of the two great intellectual achievements of the first half of the Twentieth Century: general relativity and quantum mechanics; and these are reflected in the reprinted articles. Hawking's key contributions on black hole radiation and the no-boundary condition on the origin of the universe are included. The present compilation of Stephen Hawking's most important work also includes an introduction by him, which guides the reader though the major highlights of the volume. This volume is thus an essential item in any library and will be an important reference source for those interested in theoretical physics and applied mathematics.
Time and Consistent Relativity by Lyubomir T. Gruyitch Pdf
Time and Consistent Relativity: Physical and Mathematical Fundamentals establishes a new and original theory of time relativity, which is fully consistent. It explains why Einstein’s theory of time relativity is physically meaningless and mathematically based on tacit inacceptable assumptions, and why it represents the singular case from the mathematical point of view. The consistent relativity theory established in the book represents an exit from the situation created by Einstein’s theory of time relativity. This original book presents novel results on time and its relativity that constitute the consistent relativity theory. The results are free of mistakes, inconsistencies, and paradoxes of Einstein’s time relativity theory. The author’s original discoveries and results constitute the new physical and mathematical fundamentals on time and its relativity. The book presentation is concise, clear, and self-contained. It covers the phenomenon of time and its properties and results in a definition and characterization of time. It enables the great variety of new mathematical results presented in the form of theorems and their corollaries and specifies the necessary and sufficient conditions for the corresponding statements to hold. The proofs are rigorous. This book: Explains the physical nature of time Presents the definition and characterization of time Explains the physical sense of time relativity Rejects Einstein’s time relativity theory as the general one Proves that Einstein’s time relativity theory represents a singular case valid under tacit, physically meaningless and mathematically inacceptable, assumptions Generalizes and extends the Galilean-Newtonian meaning of time and its relativity Introduces various new classes of mathematical transformations related to temporal, spatial, and velocity coordinates and proves the necessary and sufficient conditions for their validity Discovers a great specter of new results on the time uniqueness, relativity, and temporal speed Discovers and proves a great specter of new results on the velocity and its transformations Discovers and proves a great specter of new results on the light speed and its invariance and non-invariance Discovers and proves the relationship of the light speed and the upper limiting speed Opens new directions for further research in physics and mathematical physics
These days, the idea of the cyborg is less the stuff of science fiction and more a reality, as we are all, in one way or another, constantly connected, extended, wired, and dispersed in and through technology. One wonders where the individual, the person, the human, and the body are—or, alternatively, where they stop. These are the kinds of questions Hélène Mialet explores in this fascinating volume, as she focuses on a man who is permanently attached to assemblages of machines, devices, and collectivities of people: Stephen Hawking. Drawing on an extensive and in-depth series of interviews with Hawking, his assistants and colleagues, physicists, engineers, writers, journalists, archivists, and artists, Mialet reconstructs the human, material, and machine-based networks that enable Hawking to live and work. She reveals how Hawking—who is often portrayed as the most singular, individual, rational, and bodiless of all—is in fact not only incorporated, materialized, and distributed in a complex nexus of machines and human beings like everyone else, but even more so. Each chapter focuses on a description of the functioning and coordination of different elements or media that create his presence, agency, identity, and competencies. Attentive to Hawking’s daily activities, including his lecturing and scientific writing, Mialet’s ethnographic analysis powerfully reassesses the notion of scientific genius and its associations with human singularity. This book will fascinate anyone interested in Stephen Hawking or an extraordinary life in science.
The Jewish Nobel Prize in Chemistry by Isaac Benguigui Pdf
One of the outstanding and remarkable traits of Jews throughout their history, several thousand years old, has been their creativity in all fields, especially in science. They have participated in an impressive way in the questioning of values, the dismantling of dogmas, and the irruption of hidden forces. It can be stressed from the outset that the contributions of the Jews to science was out of proportion to the percentage of the population they represent. This remains true for the chemistry of the twentieth century. Through the life and work of twenty-three Nobel Prize winners in chemistry, the author gives us a fascinating story of these men, often exiles and of modest origins, whose science was their vocation and the sharing of knowledge their creed.
One of the most remarkable things about the Jewish people over the last several thousand years has been their creativity in many fields, especially in science. They have also been impressive in their participation in questioning values, dismantling dogmas, and the disruption of hidden forces. We must underscore the fact that the contribution of Jews to science was out of proportion to the percentage of the population that they represent. In illustrating the lives and work of these 33 Nobel Prize winners in physics, the author analyzes the factors which favored these prodigious breakthroughs by Jewish scholars. “In the first part of the book, the author shows us with great erudition that the quest and great respect for knowledge have always marked the Jewish communities. The second part shows us an impressive fresco of contemporary physics where, in one Nobel Prize biography after another with lively and easy-to-read texts, we follow the development of a beautiful epic through the entire twentieth century.” — from the Foreword by Maurice Jacob/CERN
