Book Description
Levenberg has a sharp merciless eye for the hazards that can intervene in the seemingly most innocuous situation. He is utterly fearless in describing the human situation as it is. At the same time humor shines through everything he writes. Alfred Kazin/Literary Critic Mitch Levenberg is a masterful storyteller. His characters walk a very fine line between the humorous and the pathetic, the farcical and the heroic as their everyday lives turn into an eerie high wire act. The results are unforgettable. Paul Violi/Poet and Critic Mitch Levenberg beautifully and poetically captures the sense of dislocation, both literal and figurative a person can feel. He writes of things seen but not quite believed, of moments where the narrator doubts his own perceptions of the way things are. His grasp of sometimes unseen connections between people and events make his stories more than just travelogues or observations; they help cut deeper, in some cases painfully so, linking events to emotions the characters do not wish to recognize or reckon with.

Book Description
The gripping, entertaining, and vividly-told narrative of a radical discovery that sent shockwaves through the scientific community and forever changed the way we understand the world. Werner Heisenberg’s “uncertainty principle” challenged centuries of scientific understanding, placed him in direct opposition to Albert Einstein, and put Niels Bohr in the middle of one of the most heated debates in scientific history. Heisenberg’s theorem stated that there were physical limits to what we could know about sub-atomic particles; this “uncertainty” would have shocking implications. In a riveting and lively account, David Lindley captures this critical episode and explains one of the most important scientific discoveries in history, which has since transcended the boundaries of science and influenced everything from literary theory to television.

Book Description
In 1932 Norbert Wiener gave a series of lectures on Fourier analysis at the Univer sity of Cambridge. One result of Wiener's visit to Cambridge was his well-known text The Fourier Integral and Certain of its Applications; another was a paper by G. H. Hardy in the 1933 Journalofthe London Mathematical Society. As Hardy says in the introduction to this paper, This note originates from a remark of Prof. N. Wiener, to the effect that "a f and g [= j] cannot both be very small". ... The theo pair of transforms rems which follow give the most precise interpretation possible ofWiener's remark. Hardy's own statement of his results, lightly paraphrased, is as follows, in which f is an integrable function on the real line and f is its Fourier transform: x 2 m If f and j are both 0 (Ix1e- /2) for large x and some m, then each is a finite linear combination ofHermite functions. In particular, if f and j are x2 x 2 2 2 both O(e- / ), then f = j = Ae- / , where A is a constant; and if one x 2 2 is0(e- / ), then both are null.

Book Description
Risk, Opportunity, Uncertainty and Other Random Models (Volume V in the Working Guides to Estimating and Forecasting series) goes part way to debunking the myth that research and development cost are somewhat random, as under certain conditions they can be observed to follow a pattern of behaviour referred to as a Norden-Rayleigh Curve, which unfortunately has to be truncated to stop the myth from becoming a reality! However, there is a practical alternative in relation to a particular form of PERT-Beta Curve. However, the major emphasis of this volume is the use of Monte Carlo Simulation as a general technique for narrowing down potential outcomes of multiple interacting variables or cost drivers. Perhaps the most common of these in the evaluation of Risk, Opportunity and Uncertainty. The trouble is that many Monte Carlo Simulation tools are ‘black boxes’ and too few estimators and forecasters really appreciate what is happening inside the ‘black box’. This volume aims to resolve that and offers tips into things that might need to be considered to remove some of the uninformed random input that often creates a misinformed misconception of ‘it must be right!’ Monte Carlo Simulation can be used to model variable determine Critical Paths in a schedule, and is key to modelling Waiting Times and cues with random arisings. Supported by a wealth of figures and tables, this is a valuable resource for estimators, engineers, accountants, project risk specialists as well as students of cost engineering.

Book Description
Currently, economics and cognitive science are heavily rooted in Newtonian physics, successfully borrowing a great deal of modeling tools from it. This is a great achievement. You do not need quantum mechanics or theories of relativity to build a house or bridge. Nevertheless, no one would deny the importance of modern theoretical physics. I believe many intellectuals have realized the need to go beyond the limitations of the Newtonian tradition for means of social science research. The big question is how to do it and how to do it right. This book aims to integrate economics and cognitive science by applying theoretical physics from a modeling perspective. During the course of this book, necessary background knowledge preparations for understanding the content topics are also briefl y provided. Thus, this book is designed to be conceptually and instrumentally self-contained. Everyone interested should be able to read it.

Book Description
WHY GOD COULD NOT CREATE THE UNIVERSE WITH A DIFFERENT DIMENSION EVEN IF IT WANTED TO or perhaps anything else. Perhaps the universe must be the way it is. It seems that what is omnipotent is mathematics, elementary arithmetic, just counting. Yet even mathematics is not powerful enough to create a universe¿there are just too many conditions, conflicting. Existence is impossible. Beyond that for there to be structure is quite inconceivable. But the universe does exist, there are galaxies, stars, even the possibility of life. That life is possible merely allows it to exist but only with the greatest good fortune does it actually occur. Intelligence is vastly less likely, ability and technology far more improbable. That we are, what we are, seem so strange, inconceivable, that we are left merely with wonder¿and, as we seem unable to realize, the need for the deepest care, responsibility and gratitude. We have been given by the unbelievable benevolence of chance, no life, but life with the most wondrous part of the universe, the ability to think, to know, to create, to wonder¿and thus the demand that we use our most awesome gifts to protect them, to protect and preserve the world in which they exist, and the life, likely so rare if not unique in the universe, which has received these astounding favors of chance, that has been given by nature its most exalted constituents. What we are requires that we enhance what we are, what we are part of, to see, understand and be grateful. An exploration of the precise conditions required for the existence of humans in the universe. ...the author does an admirable job delineating the laws of physics without becoming too bogged down in complicated jargon, and he maintains a sense of wonder about the unique and random nature of the universe. He repeatedly celebrates our highly improbable achievements as a species, marveling at our ability to use the language of abstract mathematics to unravel the mysteries of existence. ... the prevailing tone of the narrative is clear and confident, marked by a meticulous attention to detail. An...often fascinating journey through the history of the universe and mankind. -Kirkus Discoveries

Book Description
The second edition of this book deals, as the first, with the foundations of classical physics from the 'symplectic' point of view, and of quantum mechanics from the 'metaplectic' point of view. We have revised and augmented the topics studied in the first edition in the light of new results, and added several new sections. The Bohmian interpretation of quantum mechanics is discussed in detail. Phase space quantization is achieved using the 'principle of the symplectic camel', which is a deep topological property of Hamiltonian flows. We introduce the notion of 'quantum blob', which can be viewed as the fundamental phase space unit. The mathematical tools developed in this book are the theory of the symplectic and metaplectic group, the Maslov index in a rigorous form, and the Leray index of a pair of Lagrangian planes. The concept of the 'metatron' is introduced, in connection with the Bohmian theory of motion. The short-time behavior of the propagator is studied and applied to the quantum Zeno effect.

Book Description
Reality as we know it is bound by a set of constants—numbers and values that dictate the strengths of forces like gravity, the speed of light, and the masses of elementary particles. In The Constants of Nature, Cambridge Professor and bestselling author John D.Barrow takes us on an exploration of these governing principles. Drawing on physicists such as Einstein and Planck, Barrow illustrates with stunning clarity our dependence on the steadfastness of these principles. But he also suggests that the basic forces may have been radically different during the universe’s infancy, and suggests that they may continue a deeply hidden evolution. Perhaps most tantalizingly, Barrow theorizes about the realities that might one day be found in a universe with different parameters than our own.

Book Description
An up-to-date description of progress and current problems with the gravitational constant, both in terms of generalized gravitational theories and experiments either in the laboratory, using Casimir force measurements, or in space at solar system distances and in cosmological observations. Contributions cover different aspects of the state and prediction of unified theories of the physical interactions including gravitation as a cardinal link, the role of experimental gravitation and observational cosmology in discriminating between them, the problem of the precise measurement and stability of fundamental physical constants in space and time, and the gravitational constant in particular. Recent advances discussed include unified and scalar-tensor theories, theories in diverse dimensions and their observational windows, gravitational experiments in space, rotational and torsional effects in gravity, basic problems in cosmology, early universe as an arena for testing unified models, and big bang nucleosynthesis.
