Falling Felines and Fundamental Physics


Book Description

How do cats land on their feet? Discover how this question stumped brilliant minds and how its answer helped solve other seemingly impossible puzzles The question of how falling cats land on their feet has long intrigued humans. In this playful and eye-opening history, physicist and cat parent Gregory Gbur explores how attempts to understand the cat-righting reflex have provided crucial insights into puzzles in mathematics, geophysics, neuroscience, and human space exploration. The result is an engaging tumble through physics, physiology, photography, and robotics to uncover, through scientific debate, the secret of the acrobatic performance known as cat-turning, the cat flip, and the cat twist. Readers learn the solution but also discover that the finer details still inspire heated arguments. As with other cat behavior, the more we investigate, the more surprises we discover.

Stars as Laboratories for Fundamental Physics


Book Description

Much of what we know about neutrinos is revealed by astronomical observations, and the same applies to the axion, a conjectured new particle that is a favored candidate for the main component of the dark matter of the universe.




Fundamental


Book Description

Fundamental does for physics what Tim's first book, Elemental, does for chemistry: it demystifies the topic in his trademark humorous, engaging style, including the most recent developments in the field. At the start of the twentieth century, science appeared complete and the laws of nature were almost all discovered, but then we woke a sleeping giant - we discovered quantum mechanics. In the quantum realm, objects can be in two places at once. It's a place where time travel is not only possible, but necessary. It's a place where cause and effect can happen in reverse and observing something changes its state. From parallel universes to antimatter, quantum mechanics has revealed that when you get right down to it, the laws of nature are insane. The scientist J. B. S. Haldane once said, 'Reality is not only stranger than we imagine . . . it's stranger than we can imagine.' Never is this more true than with quantum mechanics; our best, most recent attempt to make sense of the fundamental laws of nature. Fundamental is a comprehensive beginner's guide to quantum mechanics, explaining not only the weirdness of the subject but the experiments that proved it to be true. Using a humorous and light-hearted approach, Fundamental tells the story of how the most brilliant minds in science grappled with seemingly impossible ideas and gave us everything from microchips to particle accelerators. Fundamental gives clear explanations of all the quantum phenomena known to modern science, without requiring an understanding of complex mathematics; tells the eccentric stories of the scientists who made these shattering discoveries and what they used them for; explains how quantum field theory (a topic not covered in detail by any other popular-science book) gave rise to particle physics and why the Higgs boson isn't the end of the story.




Why Trust a Theory?


Book Description

Do we need to reconsider scientific methodology in light of modern physics? Has the traditional scientific method become outdated, does it need to be defended against dangerous incursions, or has it always been different from what the canonical view suggests? To what extent should we accept non-empirical strategies for scientific theory assessment? Many core aspects of contemporary fundamental physics are far from empirically well-confirmed. There is controversy on the epistemic status of the corresponding theories, in particular cosmic inflation, the multiverse, and string theory. This collection of essays is based on the high profile workshop 'Why Trust a Theory?' and provides interdisciplinary perspectives on empirical testing in fundamental physics from leading physicists, philosophers and historians of science. Integrating different contemporary and historical positions, it will be of interest to philosophers of science and physicists, as well as anyone interested in the foundations of contemporary science.




A Project to Find the Fundamental Theory of Physics


Book Description

The Wolfram Physics Project is a bold effort to find the fundamental theory of physics. It combines new ideas with the latest research in physics, mathematics and computation in the push to achieve this ultimate goal of science. Written with Stephen Wolfram's characteristic expository flair, this book provides a unique opportunity to learn about a historic initiative in science right as it is happening. A Project to Find the Fundamental Theory of Physics includes an accessible introduction to the project as well as core technical exposition and rich, never-before-seen visualizations.




The Physical World


Book Description

The Physical World offers a grand vision of the essential unity of physics that will enable the reader to see the world through the eyes of a physicist and understand their thinking. The text follows Einstein's dictum that 'explanations should be made as simple as possible, but no simpler', to give an honest account of how modern physicists understand their subject, including the shortcomings of current theory. The result is an up-to-date and engaging portrait of physics that contains concise derivations of the important results in a style where every step in a derivation is clearly explained, so that anyone with the appropriate mathematical skills will find the text easy to digest. It is over half a century since The Feynman Lectures in Physics were published. A new authoritative account of fundamental physics covering all branches of the subject is now well overdue. The Physical World has been written to satisfy this need. The book concentrates on the conceptual principles of each branch of physics and shows how they fit together to form a coherent whole. Emphasis is placed on the use of variational principles in physics, and in particular the principle of least action, an approach that lies at the heart of modern theoretical physics, but has been neglected in most introductory accounts of the subject.




Fundamental Physics of Radiology


Book Description

Fundamental Physics of Radiology, Third Edition provides a general introduction to the methods involving radioactive isotopes and ultrasonic radiations. This book provides the fundamental principles upon which the clinical uses of radioactive isotopes and ultrasonic radiation depend. Organized into four sections encompassing 45 chapters, this edition begins with an overview of the basic facts about matter and energy. This text then examines the technical details of some practical X-ray tubes. Other chapters consider the action of the X-rays on the screen to produce an emission of visible light photons in amount proportional to the incident X-ray intensity. This book discusses as well the fundamental aspects of the physical principles of radiotherapy, in which most attention is being given to gamma- and X-rays. The final chapter deals with the provision of adequate barriers and protective devices to guarantee the safety of the workers concerned. This book is a valuable resource for radiologists, physicists, and scientists.




Fundamentals of Neutrino Physics and Astrophysics


Book Description

Our Universe is made of a dozen fundamental building blocks. Among these, neutrinos are the most mysterious - but they are the second most abundant particles in the Universe. This book provides detailed discussions of how to describe neutrinos, their basic properties, and the roles they play in nature.




Fundamental Concepts of Physics


Book Description

Fundamental Concepts of Physics introduces students with little scientific background to college physics. Dr. Michael J. Cardamone presents the science of physics in a nonthreatening, non-mathematical conceptual format, with emphasis on its historical and cultural foundations. While directed at non-science undergraduate college students, the text is accessible to anyone with a curiosity concerning how we arrived at our current understanding of our physical world and its place in the universe. The goal is to allow the reader to come to an understanding of what we now know and how we came to know it. The emphasis is on the large concepts rather than the mathematical details involved with attaining this understanding. After completing the study of this text, the reader should have a greater appreciation of physics in describing the observed world. Electronic ebook edition available at Powells.com.
