You never knew theoretical physics could be so simple! In this exciting and significant book, Andrew Thomas clearly illustrates the simplicity which lies behind nature at its fundamental level. It is revealed how all unifications in physics have been based on incredibly simple ideas. Using a logical approach, it is explained how the great 20th century theories of relativity and quantum mechanics share a common base, and how they can be linked using an idea so simple that anyone can understand it. An idea which is so simple it has been hidden in plain sight.

This book is aimed at the enthusiastic general reader who wants to move beyond the maths-lite popularisations in order to tackle the essential mathematics of Einstein's fascinating theories of special and general relativity. One of the cornerstones of modern physics, relativity is based on the concept of four-dimensional spacetime - curved in the vicinity of mass-energy, flat in its absence. Special relativity helps explain a huge range of non-gravitational physical phenomena and has some strangely counter-intuitive (in plain English: very weird) consequences. These include time dilation, length contraction, the relativity of simultaneity, mass-energy equivalence and an absolute speed limit. General relativity, a theory of gravity, is at the heart of our understanding of cosmology and black holes. To paraphrase Euclid, there is no royal road to relativity - you have to do the mathematics. This introductory, self-study guide is written using straightforward and accessible language, with clear derivations and explanations as well as numerous fully solved problems. For those with minimal mathematical background, the first chapter provides a crash course in foundation mathematics. The reader is then taken gently by the hand and guided through a wide range of fundamental topics, including Newtonian mechanics; the Lorentz transformations; tensor calculus; the Schwarzschild solution; simple black holes (and what different observers would see if someone was unfortunate enough to fall into one). Also covered are the mysteries of dark energy and the cosmological constant; plus relativistic cosmology, including the Friedmann equations and Friedmann-Robertson-Walker cosmological models. Following the historic 2015 LIGO detection, there is now also an additional chapter on gravitational waves. Understand even the basics of Einstein's amazing theory and the world will never seem the same again.

On July 4th, 2012, one of physics' most exhilarating results was announced: a new particle - and very likely a new kind of particle - had been discovered at the Large Hadron Collider, the huge particle accelerator designed to reproduce energies present in the universe a fraction of a second after the Big Bang. The particle's existence had been speculated on for nearly fifty years: here, finally, was proof. Professor Lisa Randall of Harvard University is one of the world's most influential theoretical physicists, and author of the bestselling Knocking on Heaven's Door and Warped Passages. In Higgs Discovery she deftly explains both this epochal discovery and it's startlingly beautiful implications.

When physics professor Chad Orzel went to the pound to adopt a dog, he never imagined Emmy. She wasn't just a friendly mutt who needed a home; she was a talking dog with an active interest in what her new owner did for a living and how it could work for her. Soon Emmy was trying to use the strange ideas of quantum mechanics for the really important things in her life: chasing critters, getting treats, and going for walks. She peppered Chad with questions: Could she use quantum tunneling to get through the neighbor's fence and chase bunnies? What about quantum teleportation to catch squirrels before they climb out of reach? Where are all the universes in which Chad drops steak on the floor? And what about the bunnies made of cheese that ought to be appearing out of nothing in the backyard? With great humor and clarity, Chad Orzel explains to Emmy, and to human readers, just what quantum mechanics is and how it works -- and why, although you can't use it to catch squirrels or eat steak, it's still bizarre, amazing, and important to every dog and human. Follow along as Chad and Emmy discuss the central elements of quantum theory, from particles that behave like waves and Heisenberg's uncertainty principle to entanglement ("spooky action at a distance") and virtual particles. Along the way, they discuss the history of the theory, such as the experiments that discovered that electrons are waves and particles at the same time, and Albert Einstein and Niels Bohr's decades-long debate over what quantum theory really meant (Einstein may have been smarter, but Bohr was right more often). Don't get caught looking less informed than Emmy. How to Teach Physics to Your Dog will show you the universe that lies beneath everyday reality, in all its randomness, uncertainty, and wonder. "Forget Schrödinger's Cat," says Emmy, "quantum physics is all about dogs." And once you see quantum physics explained to a dog, you'll never see the world the same way again.

From the Late Prof. W J Bray This is not a casual glossing over of subjects like a TV documentary, nor is it a narrative. There is some math involved, and the subject of Quantum Theory is a difficult one both to describe and to understand by scientists and laymen alike. The math presented is reduced to some basic algebra. The purpose is to look at the evidence from a philosophical and religious perspective, as well as human perception and the deconstruction of various paradoxes and decide if the evidence is compelling toward the conclusion that we are not finite beings. This is not a discussion that suggests Quantum Physics is some route to the mystical, but a discussion that suggests we are not finite. We then look at the finite nature of our cosmos and conclude, if the evidence is compelling enough, that we are infinite beings merely perceiving a finite system.That being said (from a teacher in Romania): Written by a Physicist whose expertise spans a wide range of fields, from Neuroscience Research to philosophy and religion, and who has also experienced multiple medically documented NDEs, the book suggests mathematically that reality, the Universe as we perceive it, can only exist interdependent with consciousness. Reviewing Quantum Physics from its founders' definitions up to the latest research in the field, Bray explains in detail in language every layman can understand, provided commitment to do further research available on the WWW.The text then goes on to describe how we interact with, manipulate and define the Universe, ultimately how we "paint the universe into being", to use Bray's own syntagm. He substantiates his theory with logical arguments and hard data that have been proven correct throughout a century of quantum research. After disproving beyond any reasonable doubt that consciousness is an artifact of the physical brain, by using experimental data and conclusions independently verified by leading researchers worldwide, Bray describes how consciousness creates the physical universe, how it is mathematically impossible that consciousness can be finite, and that the universe is. His conclusion that consciousness is unique for each individual is a natural outcome of his scientific, physics-based argumentation, as is the evidence that consciousness must be infinite and eternal in order to exist. We are perceiving this short, finite, physical life, while at the same time existing in the eternal consciousness, unaware of it, because we are focusing on this finite Universe as a mere perception. Bray's purpose is not to "prove" God, but to show that each of us is a unique individual consciousness that exists beyond space-time, for infinity. He goes even further to identify the truths that have been enduring and immutable throughout centuries in philosophy and religion, by distilling them from myth and dogma. In addition, by doing this, he dismisses many paradoxes in physics, religions and philosophy. Bray succeeds in convincingly intersecting science and spirituality and showing that, contrary to cognitive beliefs which are prone to constant change, Faith is an immutable spiritual state. He has studied it not only as a scientist, but has also experienced NDEs first-hand, through recurrent cardiac arrests due to a severe medical condition that brought him repeatedly to the brink of death. Thus, the NDEs are described from the perspective of a rigorous scientist who refrains from including any biased description of them. His arguments are unambiguous, devoid of metaphor or uncertainty and the book is by no means an ideological argument or exploration, although it is at odds with almost everything written to date; Bray's claims are substantiated with solid mathematical axioms. 'Quantum Temporal Dynamics,' (not related to other material using that name) is included at the end of the book, re-exploring quantum theory from scratch, and detailing mechanisms for faster- than- light travel using current technology.
