Physics Theory

Ever wonder about how light moves? What does it mean to study the smallest particles known to man? How does science measure the smallest particles in the world, such as atoms, protons, neutrons and electrons? What is ether and how did it become a source of debate in the scientific community? Studying the smallest particles known to man can be exciting work. This study of the world on the molecular level, particularly matter and energy, is the realm of Quantum Physics.

The "universe" refers to all "observable things", ranging in size from the entire cosmos to elementary particles. A guide for an enjoyable visit to the universe, this small tome on fundamental physics, cosmology, Higgs bosons, time travel, and all that is unlike any other analogous book. Its scientific statements are correct or, at least, they coincide with the opinions held by the vast majority of experts. It establishes clear distinctions between things we know for sure and things that we know that we do not know, or we do not understand.

Quantum Physics for Beginners examines the basis of all the technological innovations of today - from atomic energy to computer microelectronics, from digital clocks to lasers, semiconductor systems, photoelectric cells, and diagnostic and treatment equipment for many diseases. In short, today we can live in a "modern" way, thanks to quantum physics and its applications. This comprehensive beginners' guide to quantum mechanics explains the most important and stunning quantum experiments to show that quantum physics is real.

Each year,John Brockman, publisher of Edge.org, challenges some of the world's greatest scientists, artists, and philosophers to answer a provocative question crucial to our time. In 2014 he asked 175 brilliant minds to ponder: What scientific idea needs to be put aside in order to make room for new ideas to advance? The answers are as surprising as they are illuminating.

Are you captivated by the mysteries of the universe and the minds that unravel them? Eager to understand how a single equation transformed our understanding of everything from atoms to galaxies? Wondering how the thoughts of one visionary could redefine the boundaries of space, time, and reality itself? Dive into the extraordinary life and legacy of Albert Einstein in A Brief History of Albert Einstein - Space, Time, and Quantum Theory: E=mc² and the Foundations of Modern Physics.

In 1919, British scientists led extraordinary expeditions to Brazil and Africa to test Albert Einstein's revolutionary new theory of general relativity in what became the century's most celebrated scientific experiment. The result ushered in a new era and made Einstein a global celebrity by confirming his dramatic prediction that the path of light rays would be bent by gravity. Today, Einstein's theory is scientific fact. Yet the effort to "weigh light" by measuring the gravitational deflection of starlight during the May 29, 1919, solar eclipse has been clouded by myth and skepticism.

David Bodanis demystifies the world's most famous equation, explaining its science and bringing it to life. He makes clear the astonishing array of discoveries and consequences it made possible and its impact on our daily lives. At last, the masses can understand that Einstein did nothing less than open the door to the inner structure of the universe.

Einstein’s revolutionary scientific ideas have transformed our world, ushering in the nuclear age. The current pace of scientific and technological progress is simply astounding. So is there any place for faith in such a world? Einstein himself gave careful thought to the deepest questions of life. His towering intellectual status means he is someone worth listening to when we think through the big questions of life.

During the last 50 years, numerous physicists have tried to unravel the secrets of string theory. Yet why do these scientists work on a theory lacking experimental confirmation? Why String Theory? provides the answer, offering an easily understood and accessible panorama of the who, what, and why of this large aspect of modern theoretical physics.

In a universe filled by chaos and disorder, one physicist makes the radical argument that the growth of order drives the passage of time - and shapes the destiny of the universe.

E=mc2: It may be Einstein’s most well-known contribution to modern science, but how many people understand the thought process or physics behind this famous equation? In this collection of his seven most important essays on physics, Einstein guides the listener step-by-step through the many layers of scientific theory that formed a starting point for his discoveries.

In the beginning was the Big Bang: an unimaginably hot fire almost fourteen billion years ago in which the first elements were forged. The physical theory of the hot nascent universe—the Big Bang—was one of the most consequential developments in twentieth-century science. And yet it leaves many questions unanswered: Why is the universe so big? Why is it so old? What is the origin of structure in the cosmos? In An Infinity of Worlds, physicist Will Kinney explains a more recent theory that may hold the answers to these questions and even explain the ultimate origins of the universe.

"Relativity: The Special and the General Theory" is a seminal work by Albert Einstein, first published in 1916, designed to explain the groundbreaking theories that reshaped our understanding of the universe. In this accessible text, Einstein introduces listeners to the Special Theory of Relativity, which addresses the relationship between space and time, and the General Theory of Relativity, which expands these concepts to include gravity as the curvature of space-time caused by mass and energy.

How big is the universe? How many numbers are there? And is infinity + 1 is the same as 1 + infinity? Such questions occur to young children and our greatest minds. And they are all the same question: What is infinity? In Beyond Infinity, Eugenia Cheng takes us on a staggering journey from elemental math to its loftiest abstractions. Along the way, she considers how to use a chessboard to plan a worldwide dinner party, how to make a chicken-sandwich sandwich, and how to create infinite cookies from a finite ball of dough.

With well over 200 episodes and a dozen seasons, The Big Bang Theory is one of America's favorite television series, bringing a new class of character to mainstream television: the science nerd. In spite of its evident popularity and influence in shaping public attitudes to science and scientists, there are relatively few books that explore the show's culture and social dimension. The Science of The Big Bang Theory looks behind the comedy scenes and scripts of this long-running and successful TV show.

Number theory is the branch of mathematics that is primarily concerned with the counting numbers. Of particular importance are the prime numbers, the "building blocks" of our number system. The subject is an old one, dating back over two millennia to the ancient Greeks, and for many years has been studied for its intrinsic beauty and elegance, not least because several of its challenges are so easy to state that everyone can understand them, and yet no one has ever been able to resolve them. But number theory has also recently become of great practical importance.

Our intuition about how things should behave is usually right in the everyday world. We see the baseball soar in the air, arc, drop, and lie stationary on the ground. Through data gathered by our senses and basic knowledge of the laws of classical mechanics, the motion of a ball makes perfect sense. But enter the world of the tiniest particles on earth—the motion of electrons, the shapes of molecules—and everything we think we know about the world radically changes.

Neuroscientists have painstakingly built up an understanding of the structure of the brain. Could this help physicists understand the levels of self-organization they observe in other systems? These same physicists, meanwhile, are trying to explain how particles organize themselves into the objects around us. Could their discoveries help explain how neurons produce our conscious experience? Exploring these questions and more, George Musser tackles the extraordinary interconnections between quantum mechanics, cosmology, human consciousness, and artificial intelligence.

In this Very Short Introduction, John Heilbron draws on sources never before presented in English to cover the life and work of one of the most creative physicists of the 20th century. In addition to his role as a scientist, Heilbron considers Bohr as a statesman and Danish cultural icon, who built scientific institutions and pushed for the extension of international cooperation in science to all nation states. As a humanist he was concerned with the cultivation of all sides of the individual, and with the complementary contributions of all peoples to the sum of human culture.

Philosophy of Physics is concerned with the deepest theories of modern physics - notably quantum theory, our theories of space, time and symmetry, and thermal physics - and their strange, even bizarre conceptual implications. A deeper understanding of these theories helps both physics, through pointing the way to new theories and new applications, and philosophy, through seeing how our worldview has to change in the light of what we learn from physics.
