We human beings — who are ourselves mere collections of fundamental particles of nature — try to wonder, seek answers and gazing at the immense heavens above, we have always asked a multitude of questions: When did the first black holes form in pre-galactic halos and what is their initial mass and spin? What is the mechanism of black hole formation in galactic nuclei, and how do black holes evolve over cosmic time due to accretion and mergers? What is the role of black hole mergers in galaxy formation? Does gravity travel at the speed of light? Does the graviton have mass? How does gravitational information propagate: Are there more than two transverse modes of propagation? What is the structure of space-time just outside astrophysical black holes? Do their space times have horizons? What happens in a black hole? Many others! Understanding the Universe: Quarks, Leptons and the Big Bang is a clear, readable and self-contained introduction to chaos of physics and related areas of science. It bridges the gap and addresses the questions that are of interest to us all or at least to all of us reading this book and lead us to study science in the first place. This book concentrates on presenting the subject from the understanding perspective of physics and brings the reader right up to date with curious aspects of physics established over the last few centuries. This book assumes science a journey not a destination and the advance of knowledge is an infinite progression towards a goal that forever recedes. This book will be of interest to students, teachers and general science readers interested in fundamental ideas of physics.

Knowing the Unknown Through Science and Sufism touches on the creation of the universe, starting from the Big Bang and following through the phases of evolution until the present day, discussing the appearance of life on earth after billions of years of turmoil. It looks at the early beginnings of religion in prehistoric societies and how this progressed into organized religion as we know it today. This book explores the similarities between the scientific concepts related to evolutionary change and the concepts that Sufis have highlighted with reference to verses of the Quran. It discusses the history of mankind and the journey through theological, philosophical, and spiritual phases. The book attempts to expand on the concept of time in relation to evolution and the difficulty in defining time and why the Quran mentions different times in different verses and also on an understanding of time in the present day. The subject matter is vast, but this book has attempted to address it in a more easily accessible way.

The Big Bang, the birth of the universe, was a singular event. All of the matter of the universe was concentrated at a single point, with temperatures so high that even the familiar protons and neutrons of atoms did not yet exist, but rather were replaced by a swirling maelstrom of energy, matter and antimatter. Exotic quarks and leptons flickered briefly into existence, before merging back into the energy sea. This book explains the fascinating world of quarks and leptons and the forces that govern their behavior. Told from an experimental physicist's perspective, it forgoes mathematical complexity, using instead particularly accessible figures and apt analogies. In addition to the story of quarks and leptons, which are regarded as well-accepted fact, the author (who is a leading researcher at one of the world's highest energy particle physics laboratories) also discusses mysteries at both the experimental and theoretical frontiers, before tying it all together with the exciting field of cosmology and indeed the birth of the universe itself. The text spans the tiny world of the quark to the depths of the universe with breathtaking clarity. The casual student of science will appreciate the careful distinction between what is known (quarks, leptons and antimatter), what is suspected (Higgs bosons, neutrino oscillations and the reason why the universe has so little antimatter) and what is merely dreamed (supersymmetry, superstrings and extra dimensions). Included is an unprecedented chapter explaining the accelerators and detectors of modern particle physics experiments. The chapter discussing the hunt for the Higgs boson — currently consuming the efforts of nearly 6000 physicists — reveals drama that only big-stakes science can give. Understanding the Universe leaves the reader with a deep appreciation of the fascinating particle realm and reverence for just how much it determines the rich beauty of our universe. Since the release of the first edition, the landscape has changed. The venerable Fermilab Tevatron has ceased operations after a quarter century of extraordinary performance, to be replaced by the CERN Large Hadron Collider, an accelerator with a design energy of seven times greater than the Tevatron and a collision rate of nearly a billion collisions per second. The next few years promise to be very exciting as scientists explore this new realm. This revised edition of Understanding the Universe will leave the reader with a deep appreciation of just why physicists are so excited.

Readership: Students, scientists and lay people. Keywords:Quarks;Leptons;Accelerators;UniverseReviews: “Lincoln has an infectious love for physics … (and) demonstrates a humorous writing style that successfully engages the reader.” Publishers Weekly “The author is well equipped to write a book on the topic … It is not light reading, but worth the effort … Lincoln is careful to distinguish between what is known versus what is merely dreamed.” Mensa Bulletin “A veteran of many popular talks on physics, (Lincoln) charmingly relates the tale of humankind's almost insatiable curiosity about the ultimate nature of nature and the quest to determine the basic particles of matter. His style is engaging and obviously directed to informed lay readers, but the more scientifically minded will find it equally appealing … If digested with the notion that this topic is presented in a broad swath, both historically and scientifically, and not meant to be definitive, the work offers readers an appreciation of the investigative procedure, the accumulated body of research, and the people who did the investigating.” Library Journal “Don Lincoln, an experimentalist on DZero at Fermilab, motivates his tale of the development of particle physics, from its origins to its current state, almost entirely by experiments, a refreshing alternative to the usual theoretical treatments. Rather than posing thought experiments, Lincoln describes real experiments that have led to deeper questions and the consequent progress of particle physics … With his light and easy-to-read style, Lincoln's humor and personal tales do much to convey the flavor of modern particle physics research — a picture that is not often painted so realistically in other popular physics books. The content is more complicated than in most similar books, but this is a virtue for its intended audience, as it allows for greater depth.” Symmetry “Knowledgeably written … ‘Understanding the Universe’ provides the nonspecialist general reader with a fascinating and informative introduction to the complex world of quarks, leptons, and the forces that govern particle physics. Written especially to introduce lay readers to subatomic mysteries, (the book) discusses the Big Bang, known and proven theories, suspected hypotheses that have yet to be firmly established, cutting-edge discussions of modern particle physics experiments, and much more. Black-and-white diagrams help illustrate the amazing ideas presented with a minimum of mathematics and a maximum of awe.” Midwest Book Review “Don Lincoln takes us on a rollicking tour of the universe: The reader finds out what we particle physicists understand about it, how we arrived at that understanding and where we think we're going next with our research … Lincoln enlivens the landscape with fresh details, irreverent (yet never unkind) remarks on the cast of characters, and explanations that are homey, humorous and often completely original … In his epilogue Lincoln addresses explicitly the question of why particle physicists ask why … the real reason we do research is simply this: It's tremendously fun to figure the universe out.” American Scientist “… Lincoln offers lay readers a complete tour of particle physics …(he) writes very well, using a mixture of humor, history and analogies as well basic scientific explanations … (and) does a particularly good job of covering the full gamut of particle physics.” Choice “This book is addressed to the curious layman, with only a murky recollection of school physics, who wants to know how far mankind has gone in understanding the world around us … It is an excellent reference for any scientist who is occasionally unsure how best to explain a particular physics concept to a non-specialist audience … his understanding and explanations of complex phenomena are excellent and the book strikes a balance between depth and accessibility.” CERN Courier “The author faces complex topics in a very simple and clever way without using mathematics but by simple (and suitable) analogies. The reading is intriguing and very flowing and, sometimes, very entertaining. The book is peppered with amusing anecdotes that make reading smoother and funny. This book is a masterpiece of scientific disclosure. I recommend its reading for those people who want to delve into the wonders of modern Physics.” Zentralblatt MATH

From 5 to 15 August 1984, a group of 79 physicists from 61 laboratories in 26 countries met in Erice for the 22nd Course of the International School of Subnuclear Physics. The countries represented were Austria, Belgium, Brazil, Bulgaria, Canada, People's Republic of China, Denmark, the Federal Republic of Germany, France, Greece, Hungary, Iran, Israel, Italy, Japan, Korea, Malaysia, Mexico, the Netherlands, Pakistan, Poland, Sweden, Switzerland, Turkey, the United Kingdom, the United States of America. The School was sponsored by the Italian Ministry of Public Education (MPI), the Italian Ministry of Scientific and Technologi cal Research (MRST), the Regional Sicilian Government (ERS), and the Weizmann Institute of Science. The programme of the School was devoted to a review of the most significant results in theoretical and experimental research work on the interactions between what we believe today are the point like constituents of the world: quarks and leptons. It should however not be forgotten that many problems are still to be understood: especially in the forefront of the correla tion between quarks and leptons. This game started in 1966 with the proposal for "leptonic quarks" and went on with "preons" and "rishons" just to quote the most famous attempts to unify these two worlds.

Do current scientific discoveries support or contradict the story of creation in the Bible? Does science give evidence for or against God’s existence? Does it matter what you think about origins, science, and the Bible? Does your understanding of science and creation affect your daily living or your relationship with God? In The Creator Revealed, author and physicist Dr. Michael G. Strauss explores these central questions about science and faith in simple and entertaining language, showing how modern scientific discoveries about the origin and design of the universe proclaim the character of God and agree with the biblical story of creation. For the Christian confronted with possible inconsistencies between faith and science, and for the skeptic who believes modern science has shown that belief in God is unnecessary, The Creator Revealed can demonstrate the glory, power, and wonder of God by looking at science, the Bible, and the effect that truth has on people’s lives. Reconciling the truth of scripture with the truth of science can change your perspective and your life. The message of The Creator Revealed will expand your idea of who God is, increase your faith in him, and provide a way to share this revelation of God in creation with others.

In Natural Kinds and Genesis: The Classification of Material Entities, Stewart Umphrey raises and answers two questions: What is it to be a natural kind? And are there in fact any natural kinds? First, using the everyday understanding of things, he argues that natural kinds may be understood as classes or as types, and that the members or tokens of such kinds are individual continuants. A continuant is essentially a being-in-becoming, a material thing which changes and yet remains the same, in virtue of its nature or essence, as long as it exists. In the primary sense of the term, then, a natural kind is a class whose members closely resemble one another substantially, in virtue of their essences. Alternatively, it is a type whose tokens exemplify it in virtue of their essences. To answer the second question, one must make use of relevant scientific theories as well. Umphrey agrees with scientific essentialists that there are natural kinds, but he argues that most of the chemical, physical, and biological kinds posited in current theories are not natural kinds in the primary sense of the term. The natural-kinds realism he affirms is thus quite restricted: it requires the existence of enduring things which closely resemble one another in virtue of their essences, and such things exist, apparently, only if they have come into being, or emerged, in the course of symmetry-breaking events. Natural Kinds and Genesis will be of interest to philosophers of science and to those interested in the metaphysics of natural kinds and their members.

Since A BRIEF HISTORY OF TIME scientists have been in the midst of a revolution in cosmology. Gradually, astronomers and physicists are answering questions that have plagued mankind since prehistory: how was the universe born, how will it end? They are even now peering into the cradle of the universe - and into its grave. By the beginning of next year, scientists will have a clue to some of the answers. These will be among the greatest triumphs of science. This book tells that story and will reveal results of the most advanced experiments in cosmology ever conducted. It's a tale of men solving the insoluble, of the controversy and anger of rivals after the same goal. Even more thrillingly - it is a lucid explanation of new scientific ideas that stretch man's powers of understanding to their highest levels.

What is the origin of the universe? What was there before the universe appeared? We are currently witnessing a second Copernican revolution: neither our Earth and Sun, nor our galaxy, nor even our universe, are the end of all things. Beyond our world, in an endless multiverse, are innumerable other universes, coming and going, like ours or different. Fourteen billion years ago, one of the many bubbles constantly appearing and vanishing in the multiverse exploded to form our universe. The energy liberated in the explosion provided the basis for all the matter our universe now contains. But how could this hot, primordial plasma eventually produce the complex structure of our present world? Does not order eventually always lead to disorder, to an increase of entropy? Modern cosmology is beginning to find out how it all came about and where it all might lead. Before Time Began tells that story.
