Void
Author: James Owen Weatherall
language: en
Publisher: Yale University Press
Release Date: 2016-11-22
The New York Times bestselling author of The Physics of Wall Street “deftly explains all you wanted to know about nothingness—a.k.a. the quantum vacuum” (Priyamvada Natarajan, author of Mapping the Heavens). James Owen Weatherall’s bestselling book, The Physics of Wall Street, was named one of Physics Today’s five most intriguing books of 2013. In this work, he takes on a fundamental concept of modern physics: nothing. The physics of stuff—protons, neutrons, electrons, and even quarks and gluons—is at least somewhat familiar to most of us. But what about the physics of nothing? Isaac Newton thought of empty space as nothingness extended in all directions, a kind of theater in which physics could unfold. But both quantum theory and relativity tell us that Newton’s picture can’t be right. Nothing, it turns out, is an awful lot like something, with a structure and properties every bit as complex and mysterious as matter. In his signature lively prose, Weatherall explores the very nature of empty space—and solidifies his reputation as a science writer to watch. Included on the 2017 Best Book List by the American Association for the Advancement of Science (AAAS) “An engaging and interesting account.”—The Economist “Readers get a dose of biography while following such figures as Einstein, Dirac, and Newton to see how top theories about the void have been discovered, developed, and debunked. Weatherall’s clear language and skillful organization adroitly combines history and physics to show readers just how much ‘nothing really matters.’”—Publishers Weekly
Zero – Much to Do About Nothing?
Zero – Much to Do About Nothing? is a thought-provoking work that delves into the complexities of defining “zero” in various fields, from mathematics and physics to pharmacology and food safety. Drawing on his extensive experience in teaching, research and managing a USDA-supported chemical food safety program, Jim E. Riviere provides readers with practical examples and case studies that highlight the challenges of defining “zero” in different contexts across a wide range of fields. In his four decades of university teaching, doing research in pharmacology, toxicology, biomathematics and nanoscience, Dr. Riviere has repeatedly encountered the concept of “zero” and the broad parameters utilized to achieve a proper definition. "Zero” enters when discussions concern defining "nothing", "negligible", "very small", "below level of detection", "absence of effect" or "safe". This renders the term “zero” incredibly confusing to scientists, practitioners and regulators. This book explores the origin of the concept of “zero” in mathematics, physics, chemistry and statistics and how these concepts migrated to fields such as pharmacology, toxicology, cancer research and food safety, as well as to the legal profession in the form of regulatory science and policy. Specific chapters deal with the application of “zero” to these distinct fields. The main focus throughout the book is to illustrate how important context is to the definition of “zero”. This has assumed greater relevance today with the advent of nanoscience where “small” implies different physical and chemical behavior and the use of artificial Intelligence to analyze vast troves of data from the web. The goal of the book is to provide much-needed clarity about "zero" and break down the many issues preventing it. Riviere expertly explains how the concept of “zero” is essential to a wide range of issues, from defining negligible amounts of a substance to determining the safety of a product or process. He shows how the term “zero” can have different meanings in different fields and how this can lead to confusion and misunderstandings among scientists, practitioners and regulators. Whether you're working in Food Safety, Chemistry, Pharmacology, Mathematics, Physics or beyond, Zero – Much to Do About Nothing? is a relatable book that will deepen your understanding of the concept of “zero” and its diverse applications.
A Universe from Nothing
Author: Lawrence M. Krauss
language: en
Publisher: Simon and Schuster
Release Date: 2012-01-10
Bestselling author and acclaimed physicist Lawrence Krauss offers a paradigm-shifting view of how everything that exists came to be in the first place. “Where did the universe come from? What was there before it? What will the future bring? And finally, why is there something rather than nothing?” One of the few prominent scientists today to have crossed the chasm between science and popular culture, Krauss describes the staggeringly beautiful experimental observations and mind-bending new theories that demonstrate not only can something arise from nothing, something will always arise from nothing. With a new preface about the significance of the discovery of the Higgs particle, A Universe from Nothing uses Krauss’s characteristic wry humor and wonderfully clear explanations to take us back to the beginning of the beginning, presenting the most recent evidence for how our universe evolved—and the implications for how it’s going to end. Provocative, challenging, and delightfully readable, this is a game-changing look at the most basic underpinning of existence and a powerful antidote to outmoded philosophical, religious, and scientific thinking.
