Albert Einstein was one of the principal founders of the quantum and relativity theories. Until 1925, when the BoseOCoEinstein statistics was discovered, he made great contributions to the foundations of quantum theory. However, after the discovery of quantum mechanics by Heisenberg and wave mechanics by SchrAdinger, with the consequent development of the principles of uncertainty and complementarity, it would seem that Einstein''s views completely changed. In his theory of the Brownian motion, Einstein had invoked the theory of probability to establish the reality of atoms and molecules; but, in 1916OCo17, when he wished to predict the exact instant when an atom would radiate OCo and developed his theory of the A and B coefficients OCo he wondered whether the OC quantum absorption and emission of light could ever be understood in the sense of the complete causality requirement, or would a statistical residue remain? I must admit that there I lack the courage of my convictions. But I would be very unhappy to renounce complete causalityOCO, as he wrote to his friend Max Born. However, he wrote later to Born that quantum mechanics OC is certainly imposingOCO, but OC an inner voice tells me that it is not the real thing OC It does not bring us closer to the secret of the OCyOld OneOCO. I, at any rate, am convinced that He is not playing at diceOCO. At the 1927 and 1930 Solvay Conferences on Physics in Brussels, Einstein engaged in profound discussions with Niels Bohr and others about his conviction regarding classical determinism versus the statistical causality of quantum mechanics. To the end of his life he retained his belief in a deterministic philosophy. This highly interesting book explores Einstein''s views on the nature and structure of physics and reality.

Einstein introduced quantum entanglement in 1935 and referred to it as “spooky actions at a distance” because it seemed to conflict with his theory of special relativity. Today, some refer to it as "the greatest mystery in physics" and the 2022 Nobel Prize in Physics was even awarded for experimental confirmation of the "spookiness." While the mystery is experimentally well-established, its solution remains elusive because it is commonly believed that quantum entanglement entails that quantum mechanics is incomplete, that the world works according to "spooky actions at a distance," that causes from the future create effects in the present, that there is "superdeterministic" causal control of experimental procedures, that people can correctly disagree on the outcome of one and the same experiment, and that a single experimental measurement can produce all possible outcomes. In this book, a rigorous solution to the mystery of quantum entanglement is provided that entails none of those things. The key to this seemingly impossible feat is - to use Einstein's own language - a "principle" explanation that foregoes the need for any "constructive" explanation of quantum entanglement, such as those listed above. Ironically, the proposed principle explanation is Einstein's own relativity principle as grounded in quantum information theory. So contrary to popular belief, quantum mechanics and special relativity are far from inconsistent, as both are a consequence of the exact same relativity principle.

This volume consists of a selection of scholarly essays from literature, philosophy and history on the conception of reality as understood by Rabindranath Tagore and Albert Einstein. The nature of reality has been a long-debated issue among scientists and philosophers. Tagore (1861–1941) met Einstein (1879–1955) at the latter’s house in Kaputh, Germany on 14 July 1930 and had a long conversation on this issue. This conversation has been widely quoted and discussed by scientists, philosophers and scholars from the literary world. The important question that Tagore and Einstein discussed was whether the world is a unity dependent on humanity, or the world is a reality independent of the human factor. Einstein believed that reality is independent of the mind and the human factor. On the other hand, Tagore adopted the opposite view. Nevertheless, both Einstein and Tagore claimed to be realists — their conceptions of reality were obviously fundamentally different. Where does the difference lie? Can it be harmonized at a deeper level? This volume brings together for the first time a gamut of views on this subject from eminent scholars. It presents some key reflections on reality, language, poetry, truth, science, personality, human sciences, virtue ethics, intelligibility and creativity. It will be useful to scholars and researchers of philosophy, literature, history and political studies, as also to those interested in Tagore.

The greatest mystery of all, the enigma of Time, shone like a blinding quasar upon the eyes of the creator of the Theory of Relativity, Albert Einstein. Indeed there has been no significant thinker, from antiquity down to the present day, who has not confronted the mystery of Time and made it an essential part of his own philosophy. Even in Plotinus’ days the problem of Time was considered to be “ancient” and “continually revived”. Thinking about Time is much like ploughing the ocean. Despite this, the Twentieth Century saw an unprecedented and new operational definition set forth by Einstein, who stripped the notion of Time of all metaphysical content, and made it ontologically eliminable. The verdict in our days is, "Time does not exist." Yet there have not been wanting thinkers who have attempted to swim against the current, to throw down the gauntlet to “the Murderer of Time”, to the Demolisher of the Absolute, showing that the Time is not an illusion, Time is real. These stirring moments in the history of intellectual endeavour are collected here, revivifying the philosophical face of every dissident. The subject is interesting not only to experts in the field, but also to every inquiring mind thirsting for historical truth. The reader who is fascinated by the fundamental ideas of physics and philosophy will find great satisfaction here. In addition he will find here the ultimate roots of our contemporary Weltanschaaung.

This book recalls, for nonscientific readers, the history of quantum mechanics, the main points of its interpretation, and Einstein's objections to it, together with the responses engendered by his arguments. Most popular discussions on the strange aspects of quantum mechanics ignore the fundamental fact that Einstein was correct in his insistence that the theory does not directly describe reality. While that fact does not remove the theory's counterintuitive features, it casts them in a different light.Context is provided by following the history of two central aspects of physics: the elucidation of the basic structure of the world made up of particles, and the explanation, as well as the prediction, of how objects move. This history, prior to quantum mechanics, reveals that whereas theories and discoveries concerning the structure of nature became increasingly realistic, the laws of motion, even as they became more powerful, became more and more abstract and remote from intuitive notions of reality. Newton's laws of motion gained their abstract power by sacrificing direct and intuitive contact with real experience. Arriving 250 years after Newton, the break with a direct description of reality embodied in quantum mechanics was nevertheless profound.

This book presents an account of all aspects of Einstein’s achievements in quantum theory, his own views, and the progress his work has stimulated since his death. While some chapters use mathematics at an undergraduate physics level, a path is provided for the reader more concerned with ideas than equations, and the book will benefit to anybody interested in Einstein and his approach to the quantum.

The nature of reality has been a long-debated issue among scientists and philosophers. In 1930, Rabindranath Tagore and Albert Einstein had a long conversation on the nature of reality. This conversation has been widely quoted and discussed by scientists, philosophers and scholars from the literary world. The important question that Tagore and Einstein discussed was whether the world is a unity dependent on humanity, or the world is a reality independent on the human factor. Einstein took the stand adopted by Western philosophers and mathematicians, namely that reality is something independent of the mind and the human factor. Tagore, on the other hand, adopted the opposite view. Nevertheless, both Einstein and Tagore claimed to be realists despite the fundamental differences between their conceptions of reality. Where does the difference lie? Can it be harmonized at some deeper level? Can Wittgenstein, for example, be a bridge between the two views? This collection of essays explores these two fundamentally different conceptions of the nature of reality from the perspectives of theories of space-time, quantum theory, general philosophy of science, cognitive science and mathematics.

You support a principle of relativity. Why not a principle of absolutism? You support the abolition of a spatial aether. Why not support the existence of a non-spatial aether? You believe that things can be stationary. Why not that they must be in a state of absolute motion? You believe that space and time are the proper stage in which reality should unfold. Why not in a Singularity of non-space and non-time? Is that not a mind, even a "Mind of God?" Don't you want to hack the Mind of God? You think everything should be about particles in a void, as the ancient Atomists said. Why not waves in a Singularity? Waves are dimensionless "atoms" with an atomic number of zero. You think everything should be about matter, with atomic number of one and greater. Why are you so afraid of zero? Why does it torment you so? Why shouldn't everything start with light – massless, and maximally length contracted and time dilated? You think everything should be about science. Why not about mathematics? You think everything should be about the senses. Why not about reason and logic? Should the scientific method start with exercising the senses or exercising reason? What kind of "rational" subject begins by claiming that something else – sensing – is more important than reasoning? Welcome to science! Science told you a story about sensory stuff. And you believed it. Why shouldn't concepts be truer than percepts? Why shouldn't mind be truer than matter? Why shouldn't reality be a self-solving intellect rather than a lurching, mindless body, blind and dumb? Why are you so scared of belonging to a smart universe? Why do you prefer reality to be stupid? What does that say about you? Why is eternal and necessary mind rejected in favor of temporal and contingent matter? Why is a priori thinking rejected in favor of a posteriori sensing? Why shouldn't light be the master of the show? The light of reason. Light is reason. It's the carrier of the cosmic intellect. Do you have good reasons for what you believe? Do you really even know what you believe? Why shouldn't mathematics have an ontology? Why shouldn't mathematics exist as light, as waves, as dimensionless sinusoids with zero mass and atomic number zero? Why are you so horrified by reality being made of mathematics, existing as light? There is only one subject that has the capacity to provide a definitive answer to existence. That's mathematics. All the rest is shinola.

Many regard Albert Einstein as the greatest physicist since Newton. What exactly did he do that is so important in physics? We provide an introduction to his physics at a level accessible to an undergraduate physics student. All equations are worked out in detail from the beginning. Einstein's doctoral thesis and his Brownian motion paper were decisive contributions to our understanding of matter as composed of molecules and atoms. Einstein was one of the founding fathers of quantum theory: his photon proposal through the investigation of blackbody radiation, his quantum theory of photoelectric effect and specific heat, his calculation of radiation fluctuation giving the first statement of wave-particle duality, his introduction of probability in the description of quantum radiative transitions, and finally the quantum statistics and Bose-Einstein condensation. Einstein's special theory of relativity gave us the famous E=mc2 relation and the new kinematics leading to the idea of the 4-dimensional spacetime as the arena in which physical events take place. Einstein's geometric theory of gravity, general relativity, extends Newton's theory to time-dependent and strong gravitational fields. It laid the ground work for the study of black holes and cosmology. This is a physics book with material presented in the historical context. We do not stop at Einstein's discovery, but carry the discussion onto some of the later advances: Bell's theorem, quantum field theory, gauge theories and Kaluza-Klein unification in a spacetime with an extra spatial dimension. Accessibility of the material to a modern-day reader is the goal of our presentation. Although the book is written with primarily a physics readership in mind (it can also function as a textbook), enough pedagogical support material is provided that anyone with a solid background in introductory physics can, with some effort, understand a good part of this presentation.
