“A rich and rewarding history of one of the most astounding ideas in physics and astronomy” (Marcia Bartusiak) – that the universe we know isn’t the only one Our books, our movies—our imaginations—are obsessed with extra dimensions, alternate timelines, and the sense that all we see might not be all there is. In short, we can’t stop thinking about the multiverse. As it turns out, physicists are similarly captivated. In The Allure of the Multiverse, physicist Paul Halpern tells the epic story of how science became besotted with the multiverse, and the controversies that ensued. The questions that brought scientists to this point are big and deep: Is reality such that anything can happen, must happen? How does quantum mechanics “choose” the outcomes of its apparently random processes? And why is the universe habitable? Each question quickly leads to the multiverse. Drawing on centuries of disputation and deep vision, from luminaries like Nietzsche, Einstein, and the creators of the Marvel Cinematic Universe, Halpern reveals the multiplicity of multiverses that scientists have imagined to make sense of our reality. Whether we live in one of many different possible universes, or simply the only one there is, might never be certain. But Halpern shows one thing for sure: how stimulating it can be to try to find out.
The story of the unlikely friendship between the two physicists who fundamentally recast the notion of time and history In 1939, Richard Feynman, a brilliant graduate of MIT, arrived in John Wheeler's Princeton office to report for duty as his teaching assistant. A lifelong friendship and enormously productive collaboration was born, despite sharp differences in personality. The soft-spoken Wheeler, though conservative in appearance, was a raging nonconformist full of wild ideas about the universe. The boisterous Feynman was a cautious physicist who believed only what could be tested. Yet they were complementary spirits. Their collaboration led to a complete rethinking of the nature of time and reality. It enabled Feynman to show how quantum reality is a combination of alternative, contradictory possibilities, and inspired Wheeler to develop his landmark concept of wormholes, portals to the future and past. Together, Feynman and Wheeler made sure that quantum physics would never be the same again.
This book shows how the ADE Coxeter graphs unify at least 20 different types of mathematical structures. These mathematical structures are of great utility in unified field theory, string theory, and other areas of physics."--Provided by publisher.
In the folklore of World War II, the memory of those heroes who staged 'Great Escapes' from POW camps still endures. But what of the other side of the coin: the villains and jack-the-lads who painstakingly plan their escapes and await their moment at great personal risk? For the first time, Prison Break, tells the stories of all the most ruthless and desperate bad boys and chancers who broke out of gaol and into the annals of criminal history. While no one applauds the escape of a murderer or predator, such men are invariably recaptured within a short time. But in Paul Buck's definitive study of Notorious Prison Escapes, we share the military-style planning and minute-by-minute tension of more 'respected' convicts: those whose major economic or political crimes provide both the criminal support network and the audacious temperament needed to escape from heavy sentences, and maximum security conditions
Each year, hundreds of newly ordained pastors enter their first congregations, unsure whether seminary training has truly prepared them for the day-to-day work of parish ministry. Clayton uses a unique epistolary format—from an older, experienced pastor to a novice—to address wisely such issues as preparing for weddings, funerals, and baptisms; planning education, evangelism, and stewardship programs; growing spiritually; developing a leadership style; and maintaining personal and professional boundaries. Highly acclaimed while used in Clayton’s Andover Newton seminary classes, this book is the perfect introduction to parish ministry for students, new pastors, and mentors.
Extra dimensions -- beyond space and time -- are the best methods for unifying gravity with particle physics. The basic extension is to five dimensions (5D), as in the induced-matter and membrane theory. This descriptive text gives an up-to-date account of the classical and quantum consequences of 5D physics. It includes topics that range from Einstein's original theory of relativity to modern views on matter. The book is mathematically precise and focuses on new ideas which appeal to readers. Examples of new ideas are: The big-bang universe, which is curved by matter in 4D, may be viewed as a smooth and empty world in 5D; the uncertainty of quantum interactions in spacetime may be regarded as the consequence of deterministic laws in higher dimensions. This book will interest people who think about the 'meaning of things'.
With his Ph.D. thesis, presented here in the format of a "Springer Theses", Paul Fulda won the 2012 GWIC thesis prize awarded by the Gravitational Wave International Committee. The impact of thermal noise on future gravitational wave detectors depends on the size and shape of the interrogating laser beam. It had been known since 2006 that, in theory, higher-order Laguerre-Gauss modes could reduce thermal noise. Paul Fulda’s research brings Laguerre-Gauss modes an enormous step forward. His work includes analytical, numerical and experimental work on table-top setups as well as experiments at the Glasgow 10m prototype interferometer. Using numerical simulations the LG33 mode was selected as the optical mode to be tested. Further research by Paul and his colleagues since then concentrated on this mode. Paul has developed and demonstrated simple and effective methods to create this mode with diffractive optics and successfully demonstrated its compatibility with the essential building blocks of gravitational wave detectors, namely, optical cavities, Michelson interferometers and opto-electronic sensing and control systems. Through this work, Laguerre-Gauss modes for interferometers have been transformed from an essentially unknown entity to a well understood option with an experimental basis.
The concept of multiple unperceived dimensions in the universe is one of the hottest topics in contemporary physics. It is essential to current attempts to explain gravity and the underlying structure of the universe. The Great Beyond begins with Einstein’s famous quarrel with Heisenberg and Bohr, whose theories of uncertainty threatened the order Einstein believed was essential to the universe, and it was his rejection of uncertainty that drove him to ponder the existence of a fifth dimension. Beginning with this famous disagreement and culminating with an explanation of the newest "brane" approach, author Paul Halpern shows how current debates about the nature of reality began as age-old controversies, and addresses how the possibility of higher dimensions has influenced culture over the past one hundred years.
The Golden Age of Hollywood, dating to the hazy depths of the early 20th Century, was an era of movie stars worshipped by the masses and despotic studio moguls issuing decrees from poolside divans… but despite the world-wide reach of the movie industry, little more than memories of that era linger amidst the freeways and apartment complexes of today’s Los Angeles. Noted archaeologistPaul G. Bahndigs into the material traces of that Tinseltown in an effort to document and save the treasures that remain. Bahn leads readers on a tour of this singular culture, from the industrial zones of film studios to the landmarks where the glamorous lived, partied, and played, from where they died and were buried to how they’ve been memorialized for posterity. The result is part history, part archaeology—enlivened with pop culture, reminiscence, and whimsy—and throughout, it feeds and deepens our fascination with an iconic place and time, not to mention the personalities who brought it to life.
An engagingly-written account of mathematical tools and ideas, this book provides a graduate-level introduction to the mathematics used in research in physics. The first half of the book focuses on the traditional mathematical methods of physics – differential and integral equations, Fourier series and the calculus of variations. The second half contains an introduction to more advanced subjects, including differential geometry, topology and complex variables. The authors' exposition avoids excess rigor whilst explaining subtle but important points often glossed over in more elementary texts. The topics are illustrated at every stage by carefully chosen examples, exercises and problems drawn from realistic physics settings. These make it useful both as a textbook in advanced courses and for self-study. Password-protected solutions to the exercises are available to instructors at www.cambridge.org/9780521854030.
Originally published in 1986. This work remains of compelling interest to those concerned with the natural sciences and their social problems. It puts forward original and unorthodox ideas about the philosophy of and sociology of science, starting from the conviction that modern societies face deep problems arising from unresolved dilemmas about the meaning, content and technical applications of the theories of nature they employ. The book draws on insights developed within a variety of traditions to explore these problems, especially the work of Edmund Husserl and modern critical theory.

This volume is the refereed proceedings of the Sixth Canadian Conference on General Relativity and Relativistic Astrophysics held in May 1995 at the University of New Brunswick. The book includes invited talks and contributed talks and posters including state-of-the-art reviews of many of the most recent important developments in gravitational physics. This book would serve as a good supplement to standard texts on the topic. It features: review articles in key areas - black holes, numerical relativity, etc.; contributions covering most of gravitational physics; useful articles for students who wish to begin exploring the issues discussed; and, invited talks given by researchers known for their ability to communicate their expertise.
This book introduces a brand new field of scientific research based upon analysis of artifacts retrieved from crashed and damaged UFOs that have come down in Russia and America. For the first time, it reveals the scientific principles behind UFO propulsion dynamics, and shows that these principles are known and recognized by today’s physicists. Potter’s analyses of these UFO mechanisms are substantiated with references to a broad array of over 300 research papers published in scientific journals! Potter correlates many of the phenomena observed firsthand by close encounter witnesses and abductees and pinpoints the common themes reported, categorizing them according to known physical principles. He produces a comprehensive orchestration of energy dynamics used inside and around UFOs. His precise and lavish illustrations allow the reader to enter directly into the realm of the advanced technological engineer and to understand, quite straightforwardly, the aliens’ methods of energy manipulation: their methods of electrical power generation; how they purposely designed their craft to employ the kinds of energy dynamics that are exclusive to space (discoverable in our astrophysics) in order that their craft may generate both attractive and repulsive gravitational forces; their control over the mass-density matrix surrounding their craft enabling them to alter their physical dimensions and even manufacture their own frame of reference in respect to time.
Business Strategy Success Principles outlines 20 essential principles for entrepreneurs and small business owners to apply in order to operate a focused, strategic, and efficient business.
This textbook, available in two volumes, has been developed from a course taught at Harvard over the last decade. The course covers principally the theory and physical applications of linear algebra and of the calculus of several variables, particularly the exterior calculus. The authors adopt the 'spiral method' of teaching, covering the same topic several times at increasing levels of sophistication and range of application. Thus the reader develops a deep, intuitive understanding of the subject as a whole, and an appreciation of the natural progression of ideas. Topics covered include many items previously dealt with at a much more advanced level, such as algebraic topology (introduced via the analysis of electrical networks), exterior calculus, Lie derivatives, and star operators (which are applied to Maxwell's equations and optics). This then is a text which breaks new ground in presenting and applying sophisticated mathematics in an elementary setting. Any student, interpreted in the widest sense, with an interest in physics and mathematics, will gain from its study.
This book explores the extent of parallelism and cross-influence between Catholic Social Teaching and the work of the world’s oldest human rights institution, the International Labour Organisation (ILO). Sometimes there is a mutual attraction between seeming opposites who in fact share a common goal. This book is about just such an attraction between a secular organisation born of the political desire for peace and justice, and a metaphysical institution much older founded to bring peace and justice on earth. It examines the principles evident in the teachings of the Catholic Church and in the secular philosophy of the ILO; together with the theological basis of the relevant provisions of Catholic Social Teaching and of the socio-political origins and basis of the ILO. The spectrum of labour rights covered in the book extends from the right to press for rights, i.e., collective bargaining, to rights themselves – conditions in work – and on to post-employment rights in the form of social security and pensions. The extent of the parallelism and cross-influence is reviewed from the issue of the Papal Encyclical of Pope Leo XIII Rerum Novarum (1891) and from the founding of the ILO in 1919. This book is intended to appeal to lay, professional and academic alike, and will be of interest to researchers and academics working in the areas of international human rights, theology, comparative philosophy, history and social and political studies. On 4 January 2021 it was granted an Imprimatur by the Roman Catholic Archbishop of Liverpool, Malcolm P. McMahon O.P., meaning that the Catholic Church is satisfied that the book is free of doctrinal or moral error.
Thisbook isnotatextbook tobecomeacquainted with thelaws ofnature. An elementaryknowledgeaboutlawsofnature,inparticularthelawsofphysics,is presupposed. Thebookisratherintendedtoprovideaclari?cationofconcepts and properties of the laws of nature. The authors would like to emphasise that this book has been developed – created – as a real teamwork. Although the chapters (and in some cases parts of the chapters) were originally written by one of the two authors, all of them were discussed thoroughly and in detail and have been revised and complemented afterwards. Even if both authors were in agreement on most of the foundational issues discussed in the book, they did not feel it necessary to balance every viewpoint. Thus some individual and personal di?erence or emphasis will still be recognisable from the chapters written by the di?erent authors. In this sense the authors feel speci?cally responsible for the chapters as follows: Mittelstaedt for Chaps. 4, 9. 3, 10, 11. 2, 12, 13 and Weingartner for Chaps. 1, 2, 3, 5, 7, 8. 2, 9. 2, 9. 4. The remaining parts are joint sections. Most of the chapters are formulated as questions and they begin with arguments pro and contra. Then a detailed answer is proposed which contains a systematic discussion of the question. This is the respective main part of the chapter. It sometimes begins with a survey of the problem by giving some important answers to it from history (cf. Chaps. 6 and 9).
Bridging the gap between modern differential geometry and the mathematical physics of general relativity, this text, in its second edition, includes new and expanded material on topics such as the instability of both geodesic completeness and geodesic incompleteness for general space-times, geodesic connectibility, the generic condition, the sectional curvature function in a neighbourhood of degenerate two-plane, and proof of the Lorentzian Splitting Theorem.;Five or more copies may be ordered by college or university stores at a special student price, available on request.

Albert Einstein, together with Theodor Kaluza and Oskar Klein, realized that extra dimensions can be used to unify the different fields of physics, as well as unifying the fields with their material sources. In fact, it was Einstein's dream to transpose the “base wood” of the matter term in his field equations to the “marble” of the geometrical term. During his lifetime, this kind of unified theory achieved only partial success. But the modern approach, outlined in this bestseller, is elegant and agrees with all the classical tests. The basic idea is to unify the source and its field using the rich algebra of higher-dimensional Riemannian geometry. In other words, space, time and matter become parts of geometry.
This book illustrates the deep roots of the geometrically nonlinear kinematics of generalized continuum mechanics in differential geometry. Besides applications to first- order elasticity and elasto-plasticity an appreciation thereof is particularly illuminating for generalized models of continuum mechanics such as second-order (gradient-type) elasticity and elasto-plasticity. After a motivation that arises from considering geometrically linear first- and second- order crystal plasticity in Part I several concepts from differential geometry, relevant for what follows, such as connection, parallel transport, torsion, curvature, and metric for holonomic and anholonomic coordinate transformations are reiterated in Part II. Then, in Part III, the kinematics of geometrically nonlinear continuum mechanics are considered. There various concepts of differential geometry, in particular aspects related to compatibility, are generically applied to the kinematics of first- and second- order geometrically nonlinear continuum mechanics. Together with the discussion on the integrability conditions for the distortions and double-distortions, the concepts of dislocation, disclination and point-defect density tensors are introduced. For concreteness, after touching on nonlinear fir st- and second-order elasticity, a detailed discussion of the kinematics of (multiplicative) first- and second-order elasto-plasticity is given. The discussion naturally culminates in a comprehensive set of different types of dislocation, disclination and point-defect density tensors. It is argued, that these can potentially be used to model densities of geometrically necessary defects and the accompanying hardening in crystalline materials. Eventually Part IV summarizes the above findings on integrability whereby distinction is made between the straightforward conditions for the distortion and the double-distortion being integrable and the more involved conditions for the strain (metric) and the double-strain (connection) being integrable. The book addresses readers with an interest in continuum modelling of solids from engineering and the sciences alike, whereby a sound knowledge of tensor calculus and continuum mechanics is required as a prerequisite.
For those interested, the book is a good and well-written overview of the work of Wesson and his collaborators. For those with a general interest in extensions of standard physics, accessibility is strongly dependent on the reader’s technical background, though the good structure of the book and copious references (including many to work by more-mainstream physicists on related topics) make that possible for those willing to invest some time.'The Observatory MagazineThis book is a summing up of the prospects for unification between relativity and particle physics based on the extension of Einstein's theory of General Relativity to five dimensions. This subject was first established by Paul Wesson in his previous best-seller, Space-Time-Matter, and discussed from a different perspective in Five-Dimensional Physics, both published by World Scientific in 1999 and 2006 respectively. This third book brings the field up to date and details many new developments and connections to particle theory and wave mechanics in particular. It was in largely finished form at the time of Paul Wesson's untimely death in 2015, and has been completed and expanded by his former student and longtime collaborator, James Overduin.
Philosopher, physicist, and anarchist Paul Feyerabend was one of the most unconventional scholars of his time. His book Against Method has become a modern classic. Yet it is not well known that Feyerabend spent many years working on a philosophy of nature that was intended to comprise three volumes covering the period from the earliest traces of stone age cave paintings to the atomic physics of the 20th century – a project that, as he conveyed in a letter to Imre Lakatos, almost drove him nuts: “Damn the ,Naturphilosophie.” The book’s manuscript was long believed to have been lost. Recently, however, a typescript constituting the first volume of the project was unexpectedly discovered at the University of Konstanz. In this volume Feyerabend explores the significance of myths for the early period of natural philosophy, as well as the transition from Homer’s “aggregate universe” to Parmenides’ uniform ontology. He focuses on the rise of rationalism in Greek antiquity, which he considers a disastrous development, and the associated separation of man from nature. Thus Feyerabend explores the prehistory of science in his familiar polemical and extraordinarily learned manner. The volume contains numerous pictures and drawings by Feyerabend himself. It also contains hitherto unpublished biographical material that will help to round up our overall image of one of the most influential radical philosophers of the twentieth century.
In this updated and expanded edition of The Tyranny of Good Intentions, Paul Craig Roberts and Lawrence M. Stratton renew their valiant campaign to reclaim that which is rightly ours–liberty protected by the rule of law. They show how crusading legislators and unfair prosecutors are remaking American law into a weapon wielded by the government and how the erosion of the legal principles we hold dear–such as habeas corpus and the prohibition against self-incrimination–is destroying the presumption of innocence. A new introduction and new chapters cover recent marquee cases and make this provocative book essential reading for anyone who cringes at the thought of unbridled state power and sees our civil liberties slowly slipping away in the name of the War on Drugs, the War on Crime, and the War on Terror.
A comprehensive guide to safeguard your livelihood, income, and standard of living through the ups and downs of any economy. Most Americans, no matter what their economic circumstances, identify themselves as middle class. A recent Gallup poll showed that 63% consider themselves upper-middle or middle class. And they are feeling burned out and squeezed, under pressure to bring home more and more money just to maintain their standard of living. Middle Class Lifeboat is an answer to that pressure, a comprehensive guide to living a more stress-free lifestyle. Part I: Safeguarding Your Livelihood: profiles the 53 best jobs to have to be self- sufficient whether the economy is up or down. Part II: Safeguarding Your Income: 6 ways to extend your earnings, that don't always involve money. Part III : Safeguarding Your Standard of Living: 10 off-the-grid lifestyle choices to increase your quality of life
This book explores the idea of time travel from the first account in English literature to the latest theories of physicists such as Kip Thorne and Igor Novikov. This very readable work covers a variety of topics including: the history of time travel in fiction; the fundamental scientific concepts of time, spacetime, and the fourth dimension; the speculations of Einstein, Richard Feynman, Kurt Goedel, and others; time travel paradoxes, and much more.
A black hole is a point of extreme mass in space-time with a radius, or event horizon, inside of which all electromagnetic radiation (including light) is trapped by gravity. A black hole is an extremely compact object, collapsed by gravity which has overcome electric and nuclear forces. It is believed that stars appreciably larger than the Sun, once they have exhausted all their nuclear fuel, collapse to form black holes: they are "black" because no light escapes their intense gravity. Material attracted to a black hole, though, gains enormous energy and can radiate part of it before being swallowed up. Some astronomers believe that enormously massive black holes exist in the centre of our galaxy and of other galaxies. This new book brings together leading research from through-out the world.

The second volume of the proceedings of the international seminar devoted to locali· zation and delocalization in quantum chemistry is divided into four parts. The first one is mainly concerned with the localizability of electrons in ionized and exited states. The second part shows how is it possible to take advantage of the localizability of electrons to compute molecular wave-functions. The third part of the book is an homogeneous analysis of the electronic collective excitation and of the motion of excitons in organic solids. The last section is devoted to the study of the role of electron localizability in the chemical reactivity of molecules. Concluding remarks are concerned with a careful analysis of the localizability concept itself in relation with a possible interpretation of the wave-mechanics. PART I ELECTRON LOCALIZATION IN IONIZED AND EXCITED STATES APPLICATIONS OF PAIR DENSITY ANALYSIS R. CONSTANCIEL and L. ESNAULT Centre de Mecanique Ondulatoire Appliquee, Paris, France Abstract. The method of pair density analysis is applied to various kinds of calculations. We examine the influence of the quality of the wavefunction and of the nuclear configuration; the problem of hybridization is discussed, as weIl as the relations between separability and excitation.
What is church's true foundation? Was the Christian church founded by Jesus, or does 'the Eucharist make the church'? Paul Avis sets out his own answer to these questions. Gathering a wide range of critical scholarship, he argues that there is something solid and dependable at the foundation of the church's life and mission. Avis argues that Jesus wanted a church in a sense, but not as we know it. Christ proclaimed the gospel of the Kingdom and his disciples proclaimed the gospel whose content was Jesus himself, the Kingdom in person. The church is battered and divided, but at its core is a treasure that is indestructible – the gospel of Christ, embodied in word and sacrament. A central theme of the book is the relationship between the church and Christ, the church and the gospel, the church and the Kingdom. Jesus Christ, crucified and risen, is the sole foundation of the church, but he cannot be without his people.
