What If the Earth Had Two Moons?: And Nine Other Thought-Provoking Speculations on the Solar System
Neil F. Comins - 2010
In What If the Earth Had Two Moons, Neil Comins leads us on a fascinating ten-world journey as we explore what our planet would be like under alternative astronomical conditions. In each case, the Earth would be different, often in surprising ways.
The title chapter, for example, gives us a second moon orbiting closer to Earth than the one we have now. The night sky is a lot brighter, but that won't last forever. Eventually the moons collide, with one extra-massive moon emerging after a period during which Earth sports a Saturn-like ring.
This and nine and other speculative essays provide us with insights into the Earth as it exists today, while shedding new light on the burgeoning search for life on planets orbiting other stars.
Appealing to adult and young adult readers alike, this book follows on the author's previous bestseller, What If the Moon Didn't Exist?, with completely new scenarios backed by the latest astronomical research.
The Little Book of String Theory
Steven S. Gubser - 2010
String theory has been called the "theory of everything." It seeks to describe all the fundamental forces of nature. It encompasses gravity and quantum mechanics in one unifying theory. But it is unproven and fraught with controversy. After reading this book, you'll be able to draw your own conclusions about string theory.Steve Gubser begins by explaining Einstein's famous equation "E = mc2," quantum mechanics, and black holes. He then gives readers a crash course in string theory and the core ideas behind it. In plain English and with a minimum of mathematics, Gubser covers strings, branes, string dualities, extra dimensions, curved spacetime, quantum fluctuations, symmetry, and supersymmetry. He describes efforts to link string theory to experimental physics and uses analogies that nonscientists can understand. How does Chopin's Fantasie-Impromptu relate to quantum mechanics? What would it be like to fall into a black hole? Why is dancing a waltz similar to contemplating a string duality? Find out in the pages of this book."The Little Book of String Theory" is the essential, most up-to-date beginner's guide to this elegant, multidimensional field of physics.
Quantum Computing Since Democritus

There are also extended discussions about time travel, Newcomb's Paradox, the anthropic principle and the views of Roger Penrose. Aaronson's informal style makes this fascinating book accessible to readers with scientific backgrounds, as well as students and researchers working in physics, computer science, mathematics and philosophy.
The View from the Center of the Universe: Discovering Our Extraordinary Place in the Cosmos
Joel R. Primack - 2006
For four hundred years, since early scientists discovered that the universe did not revolve around the earth, people have felt cut off-adrift in a meaningless cosmos. That is about to change. In their groundbreaking new book, The View from the Center of the Universe, Joel R. Primack, Ph.D., one of the world's leading cosmologists, and Nancy Ellen Abrams, a philosopher and writer, use recent advances in astronomy,physics, and cosmology to frame a compelling new theory of how to understand the universe and our role in it. While most of us think of the universe as empty space peppered with stars separated by vast distances, the truth, the authors argue, is far richer and more meaningful. For the first time in history, we know that the universe is more coherent and spiritually significant than anyone ever imagined and that our place in it is actually central to the expanding universe in important ways. According to Primack and Abrams, this new cosmology clarifies how the universe operates, what it's made of, how it may have originated, and how it is evolving. Even more surprising, these startling ideas spring from both cutting-edge science and the metaphors of ancient symbols. The result is a very human book that satisfies our fundamental need for order and meaning in our world and in our lives.
Speakable and Unspeakable in Quantum Mechanics
John Stewart Bell - 1987
This work has played a major role in the development of our current understanding of the profound nature of quantum concepts and of the fundamental limitations they impose on the applicability of the classical ideas of space, time and locality. This book contains all of John Bell's published and unpublished papers on the conceptual and philosophical problems of quantum mechanics.
Relativity Visualized: The Gold Nugget of Relativity Books
Lewis Carroll Epstein - 1984
By replacing equations with diagrams, the book allows non-specialist readers to fully understand the concepts in relativity without the slow, painful progress so often associated with a complicated scientific subject. It allows readers not only to know how relativity works, but also to intuitively understand it.
Einstein and the Quantum: The Quest of the Valiant Swabian
A. Douglas Stone - 2013
Einstein famously rejected quantum mechanics, observing that God does not play dice. But, in fact, he thought more about the nature of atoms, molecules, and the emission and absorption of light--the core of what we now know as quantum theory--than he did about relativity.A compelling blend of physics, biography, and the history of science, "Einstein and the Quantum" shares the untold story of how Einstein--not Max Planck or Niels Bohr--was the driving force behind early quantum theory. It paints a vivid portrait of the iconic physicist as he grappled with the apparently contradictory nature of the atomic world, in which its invisible constituents defy the categories of classical physics, behaving simultaneously as both particle and wave. And it demonstrates how Einstein's later work on the emission and absorption of light, and on atomic gases, led directly to Erwin Schrodinger's breakthrough to the modern form of quantum mechanics. The book sheds light on why Einstein ultimately renounced his own brilliant work on quantum theory, due to his deep belief in science as something objective and eternal.A book unlike any other, "Einstein and the Quantum" offers a completely new perspective on the scientific achievements of the greatest intellect of the twentieth century, showing how Einstein's contributions to the development of quantum theory are more significant, perhaps, than even his legendary work on relativity.
Quantum Man: Richard Feynman's Life in Science
Lawrence M. Krauss - 2011
Here Lawrence M. Krauss, himself a theoretical physicist and best-selling author, offers a unique scientific biography: a rollicking narrative coupled with clear and novel expositions of science at the limits. An immensely colorful persona in and out of the office, Feynman revolutionized our understanding of nature amid a turbulent life. Krauss presents that life—from the death of Feynman’s childhood sweetheart during the Manhattan Project to his reluctant rise as a scientific icon—as seen through the science, providing a new understanding of the legacy of a man who has fascinated millions. An accessible reflection on the issues that drive physics today, Quantum Man captures the story of a man who was willing to break all the rules to tame a theory that broke all the rules.

Love Thyself: The Message from Water III
Masaru Emoto - 1999
Water speaks for what is in our mind. Water awakens the subconscious memory in each person. . . . I now know why water is indispensable to the phenomenon of life, and why alternative therapies exist and why they’re effective. Water helped me understand religion and prayer and gave me a clue to understanding the nature of energy. It helped me understand the relationship between humanity and the cosmos. It gave me a clue to help me understand what dimensionality is. I could come one step closer to understanding the eternal theme of humanity that asks where we come from, why we are here, and what happens when we die. “Thus, for the release of this, the third volume in my series of The Message from Water, I decided to choose what the world most urgently needs at present as a theme. That is, of course, the need to eliminate war and terrorism throughout the world. The theme I have chosen is ‘prayer.’ When I thought about it more deeply, I realized that prayer is most effectively sent when each person in the world raises their energy of love by imagining a scene where the peoples of the world are living in peace. I’ve been taught this through the process of asking water many questions. “For this reason, the title of this book is ‘Love Thyself.’ First you must shine with positive, high-spirited vibrations, and be full of love. In order to do that, I think it’s important to love, thank, and respect yourself. If that’s the case, then each of those vibrations will be sent out into the world and the cosmos, and the great symphony of that harmonic vibration will wrap our planet in waves of love that serve to cherish our Heaven-granted lives. This is the message from water.” — Masaru Emoto
Light in the Darkness: Black Holes, the Universe, and Us
Heino Falcke - 2020
A man of faith ordained in the Protestant tradition, Heino Falcke wrestles with the ways in which black holes force us to confront the boundary where human life ends and the celestial begins. He also ponders why black holes are difficult for most of us to understand—comparing it to our inability to envisage our own inevitable death.Black holes develop in outer space when a massive star dies, and its matter is condensed. That extreme amount of mass contained in a small space generates a gigantic amount of gravitational force, allowing the black hole to suck up everything that comes near, including light. These astronomical wonders are the subject of our greatest scientific and philosophical theorizing—the journey to a black hole would be the journey to the end of time itself. In this way, Falcke regards them as the most exquisite representations of fear, death . . . and, surprisingly, the divine.Empirical and profound, A Light in the Darkness is the first work to examine both the physical nature and spiritual meaning of black holes, those astrophysical mysteries Falcke, calls “the epitome of merciless destruction.”
Time Travel in Einstein's Universe: The Physical Possibilities of Travel Through Time
J. Richard Gott III - 2001
