Advanced topics in quantum field theory: a lecture course
"Since the advent of Yang-Mills theories and supersymmetry in the 1970s, quantum field theory - the basis of the modern description of physical phenomena at the fundamental level - has undergone revolutionary developments. This is the first systematic and comprehensive text devoted specifically to modern field theory, bringing readers to the cutting edge of current research. The book emphasizes nonperturbative phenomena and supersymmetry. It includes a thorough discussion of various phases of gauge theories, extended objects and their quantization, and global supersymmetry from a modern perspective. Featuring extensive cross-referencing from traditional topics to recent breakthroughs in the field, it prepares students for independent research. The side boxes summarizing the main results and over 70 exercises make this an indispensable book for graduate students and researchers in theoretical physics"--
The applicability of mathematics as a philosophical problem
This book analyzes the different ways mathematics is applicable in the physical sciences, and presents a startling thesis--the success of mathematical physics appears to assign the human mind a special place in the cosmos. Mark Steiner distinguishes among the semantic problems that arise from the use of mathematics in logical deduction; the metaphysical problems that arise from the alleged gap between mathematical objects and the physical world; the descriptive problems that arise from the use of mathematics to describe nature; and the epistemological problems that arise from the use of mathematics to discover those very descriptions. The epistemological problems lead to the thesis about the mind. It is frequently claimed that the universe is indifferent to human goals and values, and therefore, Locke and Peirce, for example, doubted science's ability to discover the laws governing the humanly unobservable. Steiner argues that, on the contrary, these laws were discovered, using manmade mathematical analogies, resulting in an anthropocentric picture of the universe as "user friendly" to human cognition--a challenge to the entrenched dogma of naturalism.
Rutherford and the nature of the atom
Born in New Zealand in 1871, Rutherford came to Cambridge in 1895, where he did notable research on the electrical properties of gases. This lead to his appointment as Professor at McGill University in Montreal, where he carried out fundamental investigations on radioactivity, which he continued at the University of Manchester. Here he first put forward the nuclear structure of the atom with which his name is inseparably connected. At Cambridge, as head of the Cavendish Laboratory from 1919 to his death in 1937, he conducted and inspired work on the properties and disruption of the atomic nucleus which ushered in a new era in physics.
Simple models of complex nuclei
applications to the structure of atomic nuclei. The author systematically develops these models from the elementary level, through an introduction to tensor algebra, to the use of group theory in spectroscopy. The book's extensive and detailed appendix includes a large selection of useful formulae of tensor algebra and spectroscopy. The serious graduate student, as well as the professional physicist, will find this complete treatment of the shell model to be an invaluable addition to the literature.
Statistical mechanics
In the 1950s, the distinguished theoretical physicist Wolfgang Pauli delivered a landmark series of lectures at the Swiss Federal Institute of Technology in Zurich. His comprehensive coverage of the fundamentals of classical and modern physics was painstakingly recorded not only by his students but also by a number of collaborators whose carefully edited transcriptions resulted in a remarkable six-volume work. This volume, the fourth in the series, represents a concise course on statistical mechanics, centering on the historic development of the basic ideas and on the logical structure of the theory. Major chapter headings include General Statistical Mechanics, Brownian Motion, and Quantum Statistics. Originally published in 1973, the text remains an important resource thanks to Pauli's manner of presentation. As Victor F. Weisskopf notes in the Foreword to the series, Pauli's style is "commensurate to the greatness of its subject in its clarity and impact. . . . Pauli's lectures show how physical ideas can be presented clearly and in good mathematical form, without being hidden in formalistic expertise." Alone or as part of the complete set, this volume represents a solid introduction to statistical mechanics that will be invaluable to individuals, as well as to libraries and other institutions.
Exploring the quantum: atoms, cavities and photons
The counter-intuitive aspects of quantum physics have been for long illustrated by thought experiments, from Einstein's photon box to Schrödinger's cat. These experiments have now become real, with single particles - electrons, atoms or photons - directly unveiling the weird features of the quantum. State superpositions, entanglement and complementarity define a novel quantum logic which can be harnessed for information processing, raising great hopes for applications. This book describes a class of such thought experiments made real. Juggling with atoms and photons confined in cavities, ions or cold atoms in traps, is here an incentive to shed a new light on the basic concepts of quantum physics. Measurement processes and decoherence at the quantum-classical boundary are highlighted. This volume, which combines theory and experiments, will be of interest to students in quantum physics, teachers seeking illustrations for their lectures and new problem sets, researchers in quantum optics and quantum information.
Maccabees, Zadokites, Christians, and Qumran A New Hypothesis of Qumran Origins
This is Eisenman's original, ground-breaking work in which he criticizes the archaeology and paleography of Qumran as it had been developed by 'the specialists' up to that time and rather offers his own hypothesis-starting with the fact that it was impossible to consider that the Maccabees were the so-called "Wicked Priests" at Qumran, primarily because everything known about them agrees, for the most part, with the doctrines and positions emanating from the documents known at that time to emanate from the area known as "Qumran" along the Northwestern part of the Dead Sea and which, for that reason, we call "The Dead Sea Scrolls."In addition, he shows rather that the Establishment against whom the Qumran Scrolls were in an almost homogeneous manner directed was rather that of the Herodians and the Priests that owed both their appointment and authority to them and the Roman Governors that in due course either replaced or ruled either through or in conjunction with them. He also starts in this work to build his case for the fact that the individual came to be understood in Early Christian History as "James the Righteous" and called by everyone "James the Just"-that same individual known by everyone as as "James the Brother of Jesus"-had very much in common with "the Righteous Teacher" described and alluded to in many Dead Sea Scrolls documents. That is why this book, originally published in the early 1980s, was subtitled "A New Hypothesis of Qumran Origins." It was necessary to subject both the archaeology and paleography of Qumran-upon which the so-called "Establishment" or "Consensus of Qumran Scholars' had all based both their theories and chronology to thoroughgoing criticism. This he has done, as only someone who originally studied math and physics, could do, in a meticulously masterful fashion. No one has 'laid a glove' on his analysis since. At the same time and in parallel fashion, he starts to suggest that the 'opponent' of this individual in Early Christian History, Paul, had about the same amount of characteristics with the individual these same Qumran Documents are constantly referring to as "The Spouter of Lying," "the Liar" or "Man of Lying," or "the Scoffer" or Jester" (not someone to be taken seriously)-but, of course, this is not the same individual as "the Wicked Priest" whom prestigious Qumran 'scholars' on the highest level insist upon saddling him with because they saw "the Wicked Priest" and "the Lying Spouter" described in Qumran Documents as the same individual.Eisenman lays out here in very clear terms that the two individuals denoted as "the Wicked Priest" and "the Lying Spouter" were two distinct and absolutely separate persons-this again, despite what some 'scholars' attempt to foist on him in order to try to make him look ridiculous . No, on the contrary, in doing so, they only make themselves look ridiculous. Eisenman is very careful here - "the Spouter of Lying" is an internal opponent of "the Righteous Teacher" at Qumran. "He denied the Law in the midst of the whole Congregation"! "The Wicked Priest - certainly no 'Maccabean'/'Hasmonean' - was rather an Establishment and probably Herodian High Priest, meaning, appointed by the "Herodians" and their Roman Overlords.It was this individual who was responsible either for the destruction or the death of "the Righteous Teacher"-a situation very much paralleling a number of such similar situations described, albeit rather tendentiously, in the New Testament and, of course, by Josephus. Anyone who picks up this short Book with its copious footnotes (much of the argument being conducted there, so his gainsayers would, of course, had to have first had a look at these before criticizing him-which usually they have not) will not be disappointed. It is and was his first salvo in the ongoing and running battle he has been conducting with "Consensus" and "Establishment Scholars" ever since and - to his credit - with no little effect."
Philosophy of Science The Link Between Science and Philosophy
A great mathematician and teacher bridges the gap between science and the humanities in this exposition of the philosophy of science. Philipp Frank, a distinguished physicist and philosopher in his own right, traces the history of science from Aristotle to Einstein to illustrate philosophy’s ongoing role in the scientific process. Suitable for undergraduate students and other readers, this volume explains modern technology’s role in the gradual erosion of the rapport between physical theories and philosophical systems, and offers suggestions for restoring the link between these related areas. Dr. Frank examines the ancient Greek concept of natural science to illustrate the development of modern science; then, using geometry as an example, he charts its progress from Euclidean principles through the interpretations of Descartes, Mill, Kant, and the rise of four-dimensional and non-Euclidean geometry. Additional topics include the laws of motion, before and after innovations of Galileo and Newton; perceptions of motion, light, and relativity through the ages; metaphysical interpretations of relativistic physics; the motion of atomic objects and the phenomena and formulations of atomic physics; and the principle of causality and the validation of theories.
What little I remember
Otto Frisch took part in some of the most momentous developments in modern physics, notably the discovery of nuclear fission (a term which he coined). His work on the first atom bomb, which he saw explode in the desert 'like the light of a thousand suns', brought him into contact with figures such as Robert Oppenheimer, Edward Teller, Richard Feynman and the father of electronic computers, John von Neumann. He also encountered the physicists who had made the great discoveries of recent generations: Einstein, Rutherford and Niels Bohr. This characterful book of reminiscences sheds an engagingly personal light on the people and events behind some of the greatest scientific discoveries of this century, illustrated with a series of fascinating photographs and witty sketches by the author himself.
When things grow many: complexity, universality and emergence in nature
An accessible and interdisciplinary introduction to the applications of statistical mechanics across the sciences. The book contains a discussion of the methods of statistical physics and includes mathematical explanations alongside guidance to enable the reader to translate theory into practice.
Collected works
While Eugenio Calabi is best known for his contributions to the theory of Calabi-Yau manifolds, this Steele-Prize-winning geometer’s fundamental contributions to mathematics have been far broader and more diverse than might be guessed from this one aspect of his work. His works have deep influence and lasting impact in global differential geometry, mathematical physics and beyond. By bringing together 47 of Calabi’s important articles in a single volume, this book provides a comprehensive overview of his mathematical oeuvre, and includes papers on complex manifolds, algebraic geometry, Kähler metrics, affine geometry, partial differential equations, several complex variables, group actions and topology. The volume also includes essays on Calabi’s mathematics by several of his mathematical admirers, including S.K. Donaldson, B. Lawson and S.-T. Yau, Marcel Berger; and Jean Pierre Bourguignon. This book is intended for mathematicians and graduate students around the world. Calabi’svisionary contributions will certainly continue to shape the course of this subject far into the future.
God's dice
Science and religion go head to head in David Baddiel's debut play: a ferociously funny battle for power, fame and followers. When physics student Edie seems to prove, scientifically, the existence of God, it has far-reaching effects. Not least for her lecturer, Henry Brook, his marriage to celebrity atheist author Virginia - and his entire universe. God's Dice is an electric tragicomedy about the power of belief and our quest for truth in a fractured world. It premiered at Soho Theatre, London, in October 2019, starring Alan Davies as Henry, and directed by James Grieve.
Introduction to the theory of ferromagnetism
This introductory textbook explains the basic theoretical principles of magnetism, providing a broad coverage of the subject and indicating directions of future research. While the book is meant primarily as a textbook for first-year graduate students and advanced undergraduates in physics and engineering, it can also be a reference for practicing engineers and physicists who work in the field of magnetism. It explains the basic theoretical principles on which much of this type of research is based, with special attention to some of the shortcomings and drawbacks. The book emphasizes the foundations of different subfields, but also explores the directions of the most recent research.
Mountains oceans giants
The 27th century: beleaguered elites decide to melt the Greenland icecap. Why? - to open up a new continent, for colonisation by the unruly masses. How? - by harvesting the primordial heat of the Earth from Iceland's volcanoes. Nature fights back, and it all goes horribly wrong... In the early 1920s confirmed city-dweller Alfred Doblin - he was 15 before he saw his first cherry tree - became puzzled by a nagging sense of Nature: "I experienced Nature as a secret. Physics as the surface, begging for explanations. Textbooks... knew nothing of the secret. Every day I experienced Nature as the World Being, meaning: weight, colour, light, dark, its countless materials, as a cornucopia of processes that quietly mingle and criss-cross." Readers accustomed to following a story via Plot and Character may at first be disoriented by this epic of the future. Its structure is more symphonic than novelistic, driven by themes and motifs that emerge, fade back, emerge again in new orchestral voicings and new tempi. The prose - supple, rhythmic, harsh, elegiac, tender, unsparing - propels the reader on through scene after vivid scene. Mountains Oceans Giants is a literary counterpart to the painted dreams and nightmares of Hieronymus Bosch, in The Garden of Earthly Delights and The Last Judgement. Alfred Doblin, born in Szczecin in 1878, initially worked as a medical assistant and opened his own practice in Berlin in 1911. Doblin's first novel appeared in 1915/16. His greatest success was the novel Berlin Alexanderplatz published in 1929. In 1933 Doblin emigrated to France and finally to the USA. After the end of the 2nd World War he moved back to Germany, but then moved in 1953 with his family to Paris. He died on June 26, 1957. Berlin Alexanderplatz (translated by Michael Hofman) is published by Penguin in the UK and New York Review Books in the USA.
Mathematical Foundations Of Quantum Field Theory
The book is very different from other books devoted to quantum field theory, both in the style of exposition and in the choice of topics. Written for both mathematicians and physicists, the author explains the theoretical formulation with a mixture of rigorous proofs and heuristic arguments; references are given for those who are looking for more details. The author is also careful to avoid ambiguous definitions and statements that can be found in some physics textbooks. In terms of topics, almost all other books are devoted to relativistic quantum field theory, conversely this book is concentrated on the material that does not depend on the assumptions of Lorentz-invariance and/or locality. It contains also a chapter discussing application of methods of quantum field theory to statistical physics, in particular to the derivation of the diagram techniques that appear in thermo-field dynamics and Keldysh formalism. It is not assumed that the reader is familiar with quantum mechanics; the book contains a short introduction to quantum mechanics for mathematicians and an appendix devoted to some mathematical facts used in the book.

Representation Theory and Complex Geometry
see attached] This second edition of {it Representation Theory and Complex Geometry} provides an overview of significant advances in representation theory from a geometric standpoint. A geometrically-oriented treatment has long been desired, especially since the discovery of { l D}-modules in the early '80s and the quiver approach to quantum groups in the early '90s. The first half of the book fills the gap between the standard knowledge of a beginner in Lie theory and the much wider background needed by the working mathematician. Thus, Chapters 1-3 and 5-6 provide some basics in symplectic geometry, Borel--Moore homology, the geometry of semisimple groups, equivariant algebraic K-theory "from scratch," and the topology and algebraic geometry of flag varieties and conjugacy classes, respectively. The material covered by Chapters 5 and 6, as well as most of Chapter 3, has never been presented in book form. Chapters 3-4 and 7-8 present a uniform approach to representation theory of three quite different Weyl groups, Lie algebra sln, and the Iwahori--Hecke algebra. The results of Chapters 4 and 8, with complete proofs are not to be found elsewhere in the literature. This second edition contains substantial updates and revisions to include more standard classical results in chapters 2, 3, 5, and 6 as well as two new chapters. Chapter 9 treats the applications of { l D}-modules to Lie groups, and includes the study of * Differential operators on a semisimple group and on its flag manifold; * the famous Beilinson--Bernstein Localization Theorem reducing the study of {it g}-modules to that of { l D} modules; * the so-called Harish--Chandra holonomic system. Chapter 10 isdevoted to some very exciting developments connecting the representations of quantum groups to the geometry of "quiver varieties," introduced by Lusztig and Nakajima. The subject is closely related to many other important topics such as the McKay correspondence, semismall resolutions and Hilbert schemes. Overall, this chapter puts the representation theory of Kac--Moody algebras and quantum groups in this broader context. The exposition is practically self-contained with each chapter potentially serving as a basis for a graduate course or seminar. An excellent glossary of notation, comprehensive bibliography and extensive index round out this new edition. The techniques developed here play an essential role in the development of the Langlands program and can be successfully applied to representation theory, quantum groups and quantum field theory, affine Lie algebras, algebraic geometry, and mathematical physics.
Ultra-Wideband, Short-Pulse Electromagnetics
In 1945, Dr. Ernst Weber founded, and was the first Director of, the Microwave Research Institute (MRI) at POLYTECHNIC UNIVERSITY (at that time named the Polytechnic Institute of Brooklyn). MRI gained world-wide recognition in the 50's and 60's for its research in electromagnetic theory, antennas and radiation, network theory and microwave networks, microwave components and devices. It was also known through its series of topical symposia and the widely distributed hard bound MRI Symposium Proceedings. Rededicated as the Weber Research Institute (WRI) in 1986, the research focus today is on such areas as electromagnetic propagation and antennas, ultra broadband electromagnetics, pulse power, acoustics, gaseous electronics, plasma physics, solid state materials, quantum electronics, electromagnetic launchers, and networks. Following the MRI tradition, WRI has launched its own series of in-depth topical conferences with published proceedings. The first conference was held in October, 1990 and was entitled Directions in Electromagnetic Wave Modeling. The proceedings of the conference were published under that title by Plenum Press. This volume constitutes the Proceedings of the second WRI International Conference dealing with Ultra·Wideband Short·Pulse Electromagnetics.
