What are time and space made of? Where does matter come from? And what exactly is reality? Theoretical physicist Carlo Rovelli has spent his whole life exploring these questions and pushing the boundaries of what we know. Here he explains how our image of the world has changed over the last few dozen centuries.
For more than 30 years, Richard P. Feynman's three-volume Lectures on Physics has been known worldwide as the classic resource for students and professionals alike. Ranging from the most basic principles of Newtonian physics through such formidable theories as Einstein's general relativity, superconductivity, and quantum mechanics, Feynman's lectures stand as a monument of clear exposition and deep insight.
Every physicist agrees quantum mechanics is among humanity's finest scientific achievements. But ask what it means, and the result will be a brawl. For a century, most physicists have followed Niels Bohr's Copenhagen interpretation and dismissed questions about the reality underlying quantum physics as meaningless. A mishmash of solipsism and poor reasoning, Copenhagen endured, as Bohr's students vigorously protected his legacy, and the physics community favored practical experiments over philosophical arguments.
Warped Passages is an altogether exhilarating journey that tracks the arc of discovery from early 20th-century physics to the razor's edge of modern scientific theory. One of the world's leading theoretical physicists, Lisa Randall provides astonishing scientific possibilities that, until recently, were restricted to the realm of science fiction. Unraveling the twisted threads of the most current debates on relativity, quantum mechanics, and gravity, she explores some of the most fundamental questions posed by Nature.
From Schrodinger's cat to Heisenberg's uncertainty principle, this book untangles the weirdness of the quantum world. Quantum mechanics underpins modern science and provides us with a blueprint for reality itself. And yet it has been said that if you're not shocked by it, you don't understand it. But is quantum physics really so unknowable? Is reality really so strange? And just how can cats be half alive and half dead at the same time?
Bertrand Russell wrote that mathematics can exalt "as surely as poetry". This is especially true of one equation: ei(pi) + 1 = 0, the brainchild of Leonhard Euler, the Mozart of mathematics. More than two centuries after Euler's death, it is still regarded as a conceptual diamond of unsurpassed beauty. Called Euler's identity, or God's equation, it includes just five numbers but represents an astonishing revelation of hidden connections.

What is the connection between physics and consciousness? In this groundbreaking new audiobook, Samuel Avery presents the quantum screen, a paradigm-shifting model of perceptual consciousness and of the world. This model looks to the enigmas of modern physics to demonstrate the primacy of consciousness - the essential oneness of spirit and matter.
The young field of quantum mechanics holds out the promise that some of humanity's wildest dreams may be realized. Serious scientists, working off of theories first developed by Einstein and his colleagues 70 years ago, have been investigating the phenomenon known as "entanglement," one of the strangest aspects of the strange universe of quantum mechanics. New experiments suggest it does happen, and that it may lead to unbreakable codes, and even teleportation...
As science informs public policy, decision making, and so many aspects of our everyday lives, a scientifically literate society is crucial. In that spirit, Edge.org publisher and author of Know This, John Brockman, asks 206 of the world's most brilliant minds the 2017 Edge Question: What scientific term or concept ought to be more widely known?
The 20th century gave us two great theories of physics. The general theory of relativity describes the behavior of very large things, and quantum theory the behavior of very small things. In this landmark audiobook, John Gribbin - one of the best-known science writers of the past 30 years - presents his own version of the Holy Grail of physics, the search that has been going on for decades to find a unified "Theory of Everything" that combines these ideas into one mathematical package.
We human beings share 98 percent of our genes with chimpanzees. Yet humans are the dominant species on the planet - having founded civilizations and religions, developed intricate and diverse forms of communication, learned science, built cities, and created breathtaking works of art - while chimps remain animals concerned primarily with the basic necessities of survival. What is it about that two percent difference in DNA that has created such a divergence between evolutionary cousins?
Desperate to prove that he has found the unified field theory in the Bible, young mathematics prodigy Jacob Saylor runs away to the Middle East. But when he and his brother venture into the desert they disappear, only to return years later with no memory of where they have been. Then a group of cybernetic terrorists calling themselves The Embodied attack. Having discarded their humanity for bodies of living technology they serve their masters by secretly manipulating world events, eliminating enemies, and toppling nations.
From the author of 12 Rules for Life: An Antidote to Chaos comes a provocative hypothesis that explores the connection between what modern neuropsychology tells us about the brain and what rituals, myths, and religious stories have long narrated. A cutting-edge work that brings together neuropsychology, cognitive science, and Freudian and Jungian approaches to mythology and narrative, Maps of Meaning presents a rich theory that makes the wisdom and meaning of myth accessible to the critical modern mind.
In seven brief lessons, Italian theoretical physicist Carlo Rovelli guides listeners with admirable clarity through the most transformative physics breakthroughs of the 20th and 21st centuries. This playful, entertaining, and mind-bending introduction to modern physics, already a major best seller in Italy, explains general relativity, quantum mechanics, elementary particles, gravity, black holes, the complex architecture of the universe, and the role of humans in the strange world Rovelli describes.
In Significant Figures, acclaimed mathematician Ian Stewart introduces the visionaries of mathematics throughout history. Delving into the lives of twenty-five great mathematicians, Stewart examines the roles they played in creating, inventing, and discovering the mathematics we use today. Through these short biographies, we get acquainted with the history of mathematics.
What happens when something is sucked into a black hole? Does it disappear? Three decades ago, a young physicist named Stephen Hawking claimed that it did - and in doing so, put at risk everything we know about the fundamental laws of the universe. Leonard Susskind and Gerard 't Hooft realized the threat and responded with a counterattack that changed the course of physics.
What is economic growth? And why, historically, has it occurred in only a few places? Previous efforts to answer these questions have focused on institutions, geography, finances, and psychology. But according to MIT's anti-disciplinarian César Hidalgo, understanding the nature of economic growth demands transcending the social sciences and including the natural sciences of information, networks, and complexity. To understand the growth of economies, Hidalgo argues, we first need to understand the growth of order.
You never knew that theoretical physics could be so simple! In this exciting and significant audiobook, Andrew Thomas reveals how all unifications in physics have been based on incredibly simple ideas.
Using a logical approach, Thomas explains 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 that is so simple it has been hidden in plain sight.
Unfortunately this is not science and not philosophy, instead it is musings lightly disguised as science.
First the author DEFINES the universe of including all that is. Then defines “Absolute” as requiring something outside the system as a standard. He then concludes (basically by his own definition) that nothing in the universe can be absolute, then further concludes everything in the universe must be relative. Clearly some things in the universe are relative (spatial distance, time, velocity, momentum, energy, mass, etc.) but (unfortunately for the author’s theory) some things are not relative (charge, rest-mass, space-time distance, etc.) The author tries, in vain, to explain this away with philosophical arguments. Many more philosophical arguments follow, with no suggested confirming experiments or practical ramifications.
The author concludes that if the universe must be relative, then quantum mechanics and relativity clearly follow. Clearly? Unfortunately reasoning from first principles, without mathematical rigor, can lead to the counting of angels.
Thomas points out that relativity and QM are exactly the same, both have multiple values for measurable before measurement. Well, kind of, but these are very different. QM predicts measurable are in a superposition of states for all observers, while in relativity measurable are not in superposition, but are just relative to the observer.
The author seems somewhat naïve, and highly entranced by his own insights. It is clear from the writing that others have pointed out to the author some of the fatal flaws of his insights, but the author simply brushes these weaknesses away with musings that don’t quite make sense. He repeats his conclusions many times, as if repetition gives strength to his insights.
Thomas wonders why mainstream physicists don’t flock to accept his simple insights. He wonders if it is because his insight is too simple. This is not the reason. Instead, Thomas’s insight are not widely accepted because they are neither rigorous, verifiable, nor useful.
The author goes on to propose the universe does the best it can, without external references, to manage reality. Again, a vague proposition from which almost anything could be concluded.
The author (as is quite common) mistakes superposition with multi-position.
The author is dissatisfied with MWI and the Copenhagen interpretation of QM yet seems completely satisfied with the idea that any “Macroscopic” interaction with a quantum state causes a gradual decoherence of coherent particle phase. The term “Macroscopic” is about at vague as it gets. More interestingly, and more importantly, many measurements causing decoherence are negative, that is, NOT measuring a particle causes decoherence just as certainly as measuring a particle. It is more difficult to conclude that NOT measuring a particle somehow gradually causes decoherence of a particle which turns up very, very far away. Even more interestingly and even more importantly, is the case of entanglement where measuring one particle seems to “influence” a very distant entangled particle. This is the basis of Bell’s Inequality and EPR which are key concepts that should certainly be addressed by any unifying theory, yet the author totally ignores both Bell and EPR.
The author describes how some quantum systems decohere due to interactions with the environment. Yet this does not explain why a double slit experiment does not decohere even though it is open to the environment and can involve air, lenses, mirrors, or optical fiber yet the interference does not decohere.
The author dismisses Everett’s Multi-World Interpretation of Quantum Mechanics. Everett did not call his theory Multi-World but instead “the theory of the universal wave function” and carefully explains how observer measurements become correlated without any discontinuous wave function collapse. No splitting of worlds occurs. It is just an evolving universal wave function. I don’t accept MWI for subtle reasons, but MWI certainly should not be so lightly dismissed.
The author seems to have an out of date view of entropy, presuming entropy naturally always increases. Yet, it seems, entropy actually increases only because the universe is currently in a low entropy state and the universe is evolving towards equilibrium.
The narration is excellent, clear and with a good understanding of the material.

This is a wonderful book which explains this difficult subject as clearly and simply as possible.It certainly seems to explain the unity between Quantum Mechanics and Relativity and is a Unifying theory in my opinion. It debunks the utterly ludicrous "Many Worlds" and other slightly less unbelievable fairy tales that seem to abound among "genius " physicists! Quantum Physicists as a group seems to get so involved in details that they don't see the wood (the overview) for the trees (their linear algebra and vector space equations!). Andrew Thomas is a notable exception to this!

Good arguemnet but has no mathamatics to back up his argument. But has made me think about the bigger picture. Am still looking for the book that may give me a good solid answer that link quantum physics and general relatively.

Relative to other similar books I was left absolutely nonplussed! (See what I did there?).
I'm not an astrophysicist or a particle physicist so I cannot credibly argue about the underlying science of this book. I am reasonably scientifically literate (A level Maths, Physics, Chemistry, degree in engineering from Bristol Univ) so I guess I'm within the target demographic for this book.
From my point of view the book was neither effective as popular science (bringing complex concepts to a broader audience) nor a detailed scientific treatise. So it fell between two stools.
