THE NEW YORK TIMES BESTSELLER‘Sean Carroll has achieved something I thought impossible: a bridge between popular science and the mathematical universe of working physicists. Magnificent!’Brian Clegg, author of Ten Days in Physics that Shook the WorldImmense, strange and infinite, the world of modern physics often feels impenetrable to the undiscerning eye – a jumble of muons, gluons and quarks, impossible to explain without several degrees and a research position at CERN.But it doesn’t have to be this way!Allow world-renowned theoretical physicist and bestselling author Sean Carroll to guide you through the biggest ideas in the universe. Elegant and simple, Carroll unravels this web of theories and formulae equation by equation, getting to the heart of the truths they represent.—In Space, Time and Motion, the first book of this landmark trilogy, Carroll delves into the core of classical physics. From Euclid to Einstein, Space, Time and Motion explores the ideas which revolutionised science and forever changed our understanding of our place in the cosmos.

With a rare blend of scientific insight and writing as graceful as the theories it so deftly explains, The Elegant Universe remains the unrivaled account of the modern search for the deepest laws of nature: “a standard that will be hard to beat” (George Johnson, New York Times Book Review). In this new 25th anniversary edition, renowned physicist and author Brian Greene—“the single best explainer of abstruse concepts in the world today” (Washington Post)—updates his classic work with a new preface and epilogue summarizing the significant theoretical and experimental developments over the past quarter-century. From established science, including relativity and quantum mechanics, to the cutting edge of thinking on black holes, string theory, and quantum gravity, The Elegant Universe makes some of the most sophisticated concepts ever contemplated thoroughly accessible and entertaining, bringing us closer than ever to comprehending how the universe works.

'A majestic story' David Bodanis, Financial Times From the international bestselling author of Physics of the Impossible and Physics of the FutureThis is the story of a quest: to find a Theory of Everything. Einstein dedicated his life to seeking this elusive Holy Grail, a single, revolutionary 'god equation' which would tie all the forces in the universe together, yet never found it. Some of the greatest minds in physics took up the search, from Stephen Hawking to Brian Greene. None have yet succeeded.In The God Equation, renowned theoretical physicist Michio Kaku takes the reader on a mind-bending ride through the twists and turns of this epic journey: a mystery that has fascinated him for most of his life. He guides us through the key debates in modern physics, from Newton's law of gravity via relativity and quantum mechanics to the latest developments in string theory. It is a tale of dazzling breakthroughs and crushing dead ends, illuminated by Kaku's clarity, storytelling flair and infectious enthusiasm.The object of the quest is now within sight: we are closer than ever to achieving the most ambitious undertaking in the history of science. If successful, the Theory of Everything could simultaneously unlock the deepest mysteries of space and time, and fulfil that most ancient and basic of human desires - to understand the meaning of our lives.

How did we come to understand the force that binds the universe together? In Gravity, Brian Clegg offers a succinct history of gravity from the perspectives of great thinkers including Aristotle, Galileo, Newton, Einstein and today’s leading scientists. He explores theories of general relativity, quantum mechanics and our attempts to link the two, as well as time travel, black holes, string theory and why gravity only works at the speed of light.Gravity is anything but simple, but Brian Clegg has written the most accessible book yet on the subject - the perfect introduction to a complicated theory.

A concise but rigorous treatment of variational techniques, focussing primarily on Lagrangian and Hamiltonian systems, this book is ideal for physics, engineering and mathematics students. The book begins by applying Lagrange's equations to a number of mechanical systems. It introduces the concepts of generalized coordinates and generalized momentum. Following this the book turns to the calculus of variations to derive the Euler-Lagrange equations. It introduces Hamilton's principle and uses this throughout the book to derive further results. The Hamiltonian, Hamilton's equations, canonical transformations, Poisson brackets and Hamilton-Jacobi theory are considered next. The book concludes by discussing continuous Lagrangians and Hamiltonians and how they are related to field theory. Written in clear, simple language and featuring numerous worked examples and exercises to help students master the material, this book is a valuable supplement to courses in mechanics.

Reveals how the pyramids of Egypt were sophisticated generators of clean energy.Sharing extensive new evidence and cutting-edge research that the Great Pyramid at Giza was built as an energy-harvesting machine, Christopher Dunn details how the ancient Egyptians were generating clean power for their civilization and reveals how the pyramid builders and the great inventor Nikola Tesla were drawing from the same universal knowledge.Looking at each part of the Great Pyramid, from the internal chambers to its massive stone blocks to the pyramidion on top, Dunn reveals how the pyramids in Egypt served to stimulate the release and collection of electrons in the Earth’s crust by harmonizing seismic energy while also attenuating the accumulating stresses. Drawing on exhaustive ongoing research by NASA scientists into the phenomenon known as “earthquake lights,” the author shows how the pyramid builders were inspired by this phenomenon and learned to stress igneous rocks similar to tectonic plate movement in order to harvest the resulting electron flow, which also enabled the pyramids to mitigate any impending earthquakes. He looks in depth at recent research that supports the pyramid energy theory, including new explorations of the shafts of the Queen’s Chamber, Russian research on how the Great Pyramid can concentrate electromagnetic energy, and analysis of the scorch marks on the ceiling of the Grand Gallery, which supports the King’s Chamber explosion hypothesis. He also examines the stunning significance of the large void above the Grand Gallery discovered in 2017.Analyzing the results of extensive acoustic testing and measurements related to specific frequencies within the Great Pyramid, Dunn looks at the vibration and frequency rates found at ancient sacred sites and shows how the pyramids were tuned to the Earth’s frequency. He also includes multiple technical appendices written by experts.While the pyramids’ sophisticated energy-harvesting abilities are now in disarray and disuse, some remnants of their technologies are still there, waiting to be rediscovered and provide our civilization with an abundance of non-polluting power.

Using a welcoming and conversational style, this Student's Guide takes readers on a tour of the laws of thermodynamics, highlighting their importance for a wide range of disciplines. It will be a valuable resource for self-guided learners, students, and instructors working in physics, engineering, chemistry, meteorology, climatology, cosmology, biology, and other scientific fields. The book discusses thermodynamic properties such as temperature, internal energy, and entropy, and develops the laws through primarily observational means without extensive reference to atomic principles. This classical approach allows students to get a handle on thermodynamics as an experimental science and prepares them for more advanced study of statistical mechanics, which is introduced in the final chapter. Detailed practical examples are used to illustrate the theoretical concepts, with a selection of problems included at the end of each chapter to facilitate learning. Solutions to these problems can be found online along with additional supplemental materials.

A world-renowned physicist seeks gravity’s true nature and finds wisdom in embracing its force in her lifeClaudia de Rham has been playing with gravity her entire life. As a diver, experimenting with her body’s buoyancy in the Indian Ocean. As a pilot, soaring over Canadian waterfalls on dark mornings before beginning her daily scientific research. As an astronaut candidate, dreaming of the experience of flying free from Earth’s pull. And as a physicist, discovering new sides to gravity’s irresistible personality by exploring the limits of Einstein’s general theory of relativity. In The Beauty of Falling, de Rham shares captivating stories about her quest to gain intimacy with gravity, to understand both its feeling and fundamental nature. Her life’s pursuit led her from a twist of fate that snatched away her dream of becoming an astronaut to an exhilarating breakthrough at the very frontiers of gravitational physics.While many of us presume to know gravity quite well, the brightest scientists in history have yet to fully answer the simple question: what exactly is gravity? De Rham reveals how great minds—from Newton and Einstein to Stephen Hawking, Andrea Ghez, and Roger Penrose—led her to the edge of knowledge about this fundamental force. She found hints of a hidden side to gravity at the particle level where Einstein’s theory breaks down, leading her to develop a new theory of “massive gravity.” De Rham shares how her life’s path turned from a precipitous fall to an exquisite flight toward the discovery of something entirely new about our surprising, gravity-driven universe.

In his monumental 1687 work, Philosophiae Naturalis Principia Mathematica, known familiarly as the Principia, Isaac Newton laid out in mathematical terms the principles of time, force, and motion that have guided the development of modern physical science. Even after more than three centuries and the revolutions of Einsteinian relativity and quantum mechanics, Newtonian physics continues to account for many of the phenomena of the observed world, and Newtonian celestial dynamics is used to determine the orbits of our space vehicles. This authoritative, modern translation by I. Bernard Cohen and Anne Whitman, the first in more than 285 years, is based on the 1726 edition, the final revised version approved by Newton; it includes extracts from the earlier editions, corrects errors found in earlier versions, and replaces archaic English with contemporary prose and up-to-date mathematical forms. Newton's principles describe acceleration, deceleration, and inertial movement; fluid dynamics; and the motions of the earth, moon, planets, and comets. A great work in itself, the Principia also revolutionized the methods of scientific investigation.It set forth the fundamental three laws of motion and the law of universal gravity, the physical principles that account for the Copernican system of the world as emended by Kepler, thus effectively ending controversy concerning the Copernican planetary system. The translation - only edition of this preeminent work is truly accessible for today's scientists, scholars, and students.

Take anything in the universe, put it in a box, and heat it up. Regardless of what you start with, the motion of the substance will be described by the equations of fluid mechanics. This remarkable universality is the reason why fluid mechanics is important. The key equation of fluid mechanics is the Navier-Stokes equation. This textbook starts with the basics of fluid flows, building to the Navier-Stokes equation while explaining the physics behind the various terms and exploring the astonishingly rich landscape of solutions. The book then progresses to more advanced topics, including waves, fluid instabilities, and turbulence, before concluding by turning inwards and describing the atomic constituents of fluids. It introduces ideas of kinetic theory, including the Boltzmann equation, to explain why the collective motion of 1023 atoms is, under the right circumstances, always governed by the laws of fluid mechanics.

Professor Pollack takes us on a fantastic voyage through water, showing us a hidden universe teeming with physical activity that provides answers so simple that any curious person can understand.

In Magnitude, Kimberly Arcand and Megan Watzke take us on an expansive journey to the limits of size, mass, distance, time, and temperature in our universe, from the tiniest particle within the structure of an atom to the most massive galaxy in the universe; from the speed at which grass grows (about 2 to 6 inches a month) to the speed of light. Fully-illustrated with four-color drawings and infographics throughout and organized into sections including Size and Amount (Distance, Area, Volume, Mass, Time, Temperature), Motion and Rate (Speed, Acceleration, Density, Rotation), and Phenomena and Processes (Energy, Pressure, Sound, Wind, Computation), Magnitude shows us the scale of our world in a clear, visual way that our relatively medium-sized human brains can easily understand.

Transport barriers are observed inhibitors of the spread of substances in flows. The collection of such barriers offers a powerful geometric template that frames the main pathways, or lack thereof, in any transport process. This book surveys effective and mathematically grounded methods for defining, locating and leveraging transport barriers in numerical simulations, laboratory experiments, technological processes and nature. It provides a unified treatment of material developed over the past two decades, focusing on the methods that have a solid foundation and broad applicability to data sets beyond simple model flows. The intended audience ranges from advanced undergraduates to researchers in the areas of turbulence, geophysical flows, aerodynamics, chemical engineering, environmental engineering, flow visualization, computational mathematics and dynamical systems. Detailed open-source implementations of the numerical methods are provided in an accompanying collection of Jupyter notebooks linked from the electronic version of the book.

The third volume in Leonard Susskind's one-of-a-kind physics series cracks open Einstein's special relativity and field theoryIn the first two books in his wildly popular The Theoretical Minimum series, world-class physicist Leonard Susskind provided a brilliant first course in classical and quantum mechanics, offering readers not an oversimplified introduction, but the real thing - everything you need to start doing physics, and nothing more. Now, thankfully, Susskind and his former student Art Friedman are back, this time to introduce readers to special relativity and classical field theory. At last, waves, forces and particles will be demystified. Using their typical brand of relatively simple maths, enlightening sketches and the same fictional counterparts, Art and Lenny, Special Relativity and Classical Field Theory takes us on an enlightening journey through a world now governed by the laws of special relativity. Starting in their new watering hole, Hermann's Hideaway, with a lesson on relativity, Art and Lenny walk us through the complexities of Einstein's famous theory. Combining rigor with humour, Susskind and Friedman guarantee that Special Relativity and Classical Field Theory will become part of the reader's physics toolbox.
