This is a rare book on a rare topic: it is about 'action' and the Principle of Least Action. A surprisingly well-kept secret, these ideas are at the heart of physical science and engineering. Physics is well known as being concerned with grand conservatory principles (e.g. the conservation of energy) but equally important is the optimization principle (such as getting somewhere in the shortest time or with the least resistance). The book explains: why an optimization principle underlies physics, what action is, what `the Hamiltonian' is, and how new insights into energy, space, and time arise. It assumes some background in the physical sciences, at the level of undergraduate science, but it is not a textbook. The requisite derivations and worked examples are given but may be skim-read if desired. The author draws from Cornelius Lanczos's book "The Variational Principles of Mechanics" (1949 and 1970). Lanczos was a brilliant mathematician and educator, but his book was for a postgraduate audience. The present book is no mere copy with the difficult bits left out - it is original, and a popularization. It aims to explain ideas rather than achieve technical competence, and to show how Least Action leads into the whole of physics.

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.

Energy is at the heart of physics and of huge importance to society and yet no book exists specifically to explain it, and in simple terms. In tracking the history of energy, this book is filled with the thrill of the chase, the mystery of smoke and mirrors, and presents a fascinating human-interest story. Moreover, following the history provides a crucial aid to understanding: this book explains the intellectual revolutions required to comprehend energy, revolutions as profound as those stemming from Relativity and Quantum Theory. Texts by Descartes, Leibniz, Bernoulli, d'Alembert, Lagrange, Hamilton, Boltzmann, Clausius, Carnot and others are made accessible, and the engines of Watt and Joule are explained. Many fascinating questions are covered, including: - Why just kinetic and potential energies - is one more fundamental than the other? - What are heat, temperature and action? - What is the Hamiltonian? - What have engines to do with physics? - Why did the steam-engine evolve only in England? - Why S=klogW works and why temperature is IT. Using only a minimum of mathematics, this book explains the emergence of the modern concept of energy, in all its forms: Hamilton's mechanics and how it shaped twentieth-century physics, and the meaning of kinetic energy, potential energy, temperature, action, and entropy. It is as much an explanation of fundamental physics as a history of the fascinating discoveries that lie behind our knowledge today.

One of Many in the Universe refers to the planet Earth being one of many planets bearing intelligent life. This story begins with the first planet ever to have intelligent life, its inhabitants never suffering any aggression in any era of its evolution through armed conflict or crime. Their populace has been peaceful since the very beginning as a bipedal species, and they are the most powerful living things in the universe because of true civilization. They are not powered by magic or mutation, but by their very advanced technologies, creating extremely strong, durable, long-living bodies designed to contend with the harsh conditions of space travel. There are no last of their kind or secret select few with incredible powers; all the planet's people share these enhancements to their biology and are limited only by their interests and creativity. The problem that occurs is when one of the planet's citizens decides that despite all they have seen in the universe, their planet should develop weapons for defense against the potential unknowns. This proposal is met with staunch opposition, as it's believed that any space travelers that can approach from beyond what they've explored should have similar advances brought about by similar peace. The unlikelihood of a battle negates the need for weapons, something never necessary in this world. With a small contingent of like-minded developers who hear his idea and concur, the weapons are built, regardless of its unpopularity, on another planet in their solar system. His intuition is correct, as their world is approached by a hostile invading force. A war ensues, and the entire planet unifies in support of the defense efforts, the first battle of any kind this world will ever know. After a lopsided victory via superior technology, the world celebrates a new hero, but the battle changes his outlook on the entirety of the universe. He now knows there are multitudes of peaceful worlds that may face hostile invasion from the unknown depths of space. With global support, he embarks upon a mission to travel throughout the universe in search of hostile worlds that exhibit the potential to leave their atmosphere, accompanied by their savagery. His mission spreads carnage upon those planets he deems hostile, to prevent the potential attacks against peaceful worlds that are found and preserved. He comes in conflict with his daughter, who is born and raised during his travels, and later his son, born after his daughter's defiance, after they are exposed to and horrified by their father's mission to ensure peace in the universe.

The story of Hubble and Humason is one for the ages—and in particular, the Cosmic Age. In this compelling book, science writer Ron Voller digs deep into how and why the two scientists continued to investigate their theory of universal expansion in the face of persistent doubt, contrary theories, and calamitous world events. The evolution of this dynamic duo’s tenuous friendship and professional partnership is in many ways as intriguing as their groundbreaking work on the evolution of the universe. The book therefore traces their lives from their childhoods into their burgeoning careers, revealing how a World War and their own personal differences stood in the way of initial cooperation. It then shows how despite all this, the two opposites eventually came together in the pursuit of something far greater than themselves. This grand story is inextricably interwoven with that of Albert Einstein, Willem de Sitter, and other great physicists of the era, all of whom took part in the staggering quest to make sense of the Big Bang and what followed. “Edwin Hubble has often been considered as an island of sorts—a lone wolf of astronomy. But Voller’s book shows otherwise, as he examines Milt Humason’s essential contributions to our understanding of the expanding universe.” - Daniel Lewis, Dibner Senior Curator, History of Science & Technology, The Huntington Library

Just as Henry David Thoreau “traveled a great deal in Concord,” Nobel Prize–winning physicist Steven Weinberg sees much of the world from the window of his study overlooking Lake Austin. In Lake Views Weinberg, considered by many to be the preeminent theoretical physicist alive today, continues the wide-ranging reflections that have also earned him a reputation as, in the words of New York Times reporter James Glanz, “a powerful writer of prose that can illuminate—and sting.” This collection presents Weinberg’s views on topics ranging from problems of cosmology to assorted world issues—military, political, and religious. Even as he moves beyond the bounds of science, each essay reflects his experience as a theoretical physicist. And as in the celebrated Facing Up, the essays express a viewpoint that is rationalist, reductionist, realist, and secular. A new introduction precedes each essay, explaining how it came to be written and bringing it up to date where necessary. As an essayist, Weinberg insists on seeing things as they are, without despair and with good humor. Sure to provoke his readers—postmodern cultural critics, enthusiasts for manned space flight or missile defense, economic conservatives, sociologists of science, anti-Zionists, and religious zealots—this book nonetheless offers the pleasure of a sustained encounter with one of the most interesting scientific minds of our time.
