Einstein's Theory of Relativity Versus Classical Mechanics by Paul Marmet Pdf
Indeed, according to Straumann, the: "general conservation law of energy and momentum does not exist in general relativity". Twentieth century science moved backward in accepting again the magical creation of matter or energy from nothing, even if this is hidden in complicated mathematics. Contrary to what Einstein did, all the demonstrations in this book are compatible with the principle of mass-energy and momentum conservation. Using classical mechanics, we demonstrate that length contraction is a real physical phenomenon. We examine how this leads to the Lorentz equations. Then, we show how classical principles are sufficient to explain the advance of the perihelion of Mercury and derive Einstein's equation. The fundamental reason for this advance is illustrated with a classical apparatus. We also study the Lorentz transformations in three dimensions and the Doppler phenomenon.
Semi-technical account includes a review of classical physics (origin of space and time measurements, Ptolemaic and Copernican astronomy, laws of motion, inertia, more) and of Einstein's theories of relativity.

Einstein: On the Principle of Relativity by Albert Einstein,Harry Yoon Pdf
What is the Principle of Relativity? This short article is one of the very first scientific essays written by Einstein intended for the general, non-scientist, audience. It was originally written, in 1914, for the readers of one of the most widely-read newspapers in Germany at the time. Einstein published his two seminal papers on special relativity in 1905, and his work was gradually being recognized. In 1913, Max Planck and Walther Nernst made a trip to Zurich, where Einstein had been mostly living throughout his young adult life, to recruit Einstein (back) to Germany, which he agreed to. It was a triumphant return for Einstein. This article was published to celebrate this occasion, and his newly-earned prestige. Special relativity is based on the special principle of relativity, or simply the principle of relativity. This short newspaper article (~5 pages) explains what the principle of relativity is, at a very high level, and what kind of general interesting phenomena are predicted from the theory. The predictions of special relativity have all been confirmed, without exceptions. As for general relativity, he ended up completing his field equations of gravity at the end of 1915, and this article briefly describes why the generalization was necessary. This article was originally written by Einstein in German, and it is now in the public domain. This short booklet attempts at a new translation to give a somewhat clearer account of what Einstein wanted to convey in his original writing. A completely new English translation - 2024!
Einstein, Physics And Reality by Jagdish Mehra Pdf
Albert Einstein was one of the principal founders of the quantum and relativity theories. Until 1925, when the Bose-Einstein 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 Schrödinger, 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 1916-17, when he wished to predict the exact instant when an atom would radiate — and developed his theory of the A and B coefficients — he wondered whether the “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 causality”, as he wrote to his friend Max Born. However, he wrote later to Born that quantum mechanics “is certainly imposing”, but “an inner voice tells me that it is not the real thing … It does not bring us closer to the secret of the ‘Old One’. I, at any rate, am convinced that He is not playing at dice”. 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.

Relativity - the Special and General Theory/ Sidelights on Relativity by Albert Einstein Pdf
Relativity - The Special and General Theory/ Sidelights on Relativity is a compilation of two classic Albert Einstein physics papers. Special relativity is a theory of the structure of spacetime. It was introduced in Einstein's 1905 paper "On the Electrodynamics of Moving Bodies" (for the contributions of many other physicists see History of special relativity). Special relativity is based on two postulates which are contradictory in classical mechanics: The laws of physics are the same for all observers in uniform motion relative to one another (principle of relativity). The speed of light in a vacuum is the same for all observers, regardless of their relative motion or of the motion of the light source. The resultant theory copes with experiment better than classical mechanics. For instance, postulate 2 explains the results of the Michelson-Morley experiment. Moreover, the theory has many surprising and counterintuitive consequences. Some of these are: Relativity of simultaneity: Two events, simultaneous for one observer, may not be simultaneous for another observer if the observers are in relative motion. Time dilation: Moving clocks are measured to tick more slowly than an observer's "stationary" clock. Length contraction: Objects are measured to be shortened in the direction that they are moving with respect to the observer. Maximum speed is finite: No physical object, message or field line can travel faster than the speed of light in a vacuum. The effect of Gravity can only travel through space at the speed of light, not faster or instantaneously. Mass-energy equivalence: E = mc2, energy and mass are equivalent and transmutable. Relativistic mass, idea used by some researchers. The defining feature of special relativity is the replacement of the Galilean transformations of classical mechanics by the Lorentz transformations. General relativity is a theory of gravitation developed by Einstein in the years 1907-1915. The development of general relativity began with the equivalence principle, under which the states of accelerated motion and being at rest in a gravitational field (for example, when standing on the surface of the Earth) are physically identical. The upshot of this is that free fall is inertial motion: an object in free fall is falling because that is how objects move when there is no force being exerted on them, instead of this being due to the force of gravity as is the case in classical mechanics. This is incompatible with classical mechanics and special relativity because in those theories inertially moving objects cannot accelerate with respect to each other, but objects in free fall do so. To resolve this difficulty Einstein first proposed that spacetime is curved. In 1915, he devised the Einstein field equations which relate the curvature of spacetime with the mass, energy, and any momentum within it. Some of the consequences of general relativity are: Clocks run slower in deeper gravitational wells. This is called gravitational time dilation. Orbits precess in a way unexpected in Newton's theory of gravity. (This has been observed in the orbit of Mercury and in binary pulsars). Rays of light bend in the presence of a gravitational field. Rotating masses "drag along" the spacetime around them; a phenomenon termed "frame-dragging". The universe is expanding, and the far parts of it are moving away from us faster than the speed of light. Technically, general relativity is a theory of gravitation whose defining feature is its use of the Einstein field equations. The solutions of the field equations are metric tensors which define the topology of the spacetime and how objects move inertially.
Time magazine's "Man of the Century", Albert Einstein is the founder of modern physics and his theory of relativity is the most important scientific idea of the modern era. In this short book, Einstein explains, using the minimum of mathematical terms, the basic ideas and principles of the theory that has shaped the world we live in today. Unsurpassed by any subsequent books on relativity, this remains the most popular and useful exposition of Einstein's immense contribution to human knowledge. With a new foreword by Derek Raine.
This popular book on special relativity was first published in Moscow back in 1961 under the Russian title 'Очевидное? Нет, ещё неизведанное', which can be roughly translated as 'Is it evident? No, it's unexplored yet!'This clear exposition of the history of the development of physical ideas which eventually led to the discovery of special relativity is a narration of how physicists, from Galileo, Newton to Lorentz, Poincare and Einstein were distracted in their reflections by numerous fallacies (like aether, dragged or not). Then by experiment, it was finally understood that the laws of cinematics and dynamics of the objects moving at high speed can only be formulated with physical definions for what is distance, time or force. After that and from the two basic Einstein postulates — the principle of relativity and the constancy of the speed of light — everything else followed.As the emphasis is on being exact from the scientific viewpoint, it is also accessible to any person with a high school background. The last chapter 'Photon dreams' is addressed to science fiction fans. However, the author proves to the disappointed reader that the laws of physics that we know do not allow the construction of spaceships that could reach even the nearest stars during the life span of the team.

The Principle of Relativity by Albert Einstein,H. Minkowski,P. Mahalanobis Pdf
HISTORICAL INTRODUCTION Einstein's first paper on the restricted 'Theory of Relativity', originally published in the 'Annalen der Physik' in l905. Translated from the original German Papers by Dr. Meghnad Saha Lord Kelvin writing-in 1893, in his prefaceto the English edition of Hertz's Researches on Electric Waves, says" many workers and many thinkers have helped to build up the nineteenth century school of plenum, one ether for light, heat, electricity, magnetism; and the German and English volumes containing Hertz's electrical papers, given to the world in the last decade of the century, will be a permanent monument of the splendid consummation now realised." Ten years later, in 1905, we find Einstein declaring that " the ether will be proved to be superflous." At first sight the revolution in scientific thought brought about in the course of a single decade appears to be almost too violent. A more careful even though a rapid review of the subject will, however, show how the Theory of Relativity gradually became a historical necessity. Towards the beginning of the nineteenth century, the luminiferous ether came into prominence as a result of the brilliant successes of the wave theory in the hands of Young and Fresnel. In its stationary aspect the elastic solid ether was the outcome of the search for a medium in which the lightwaves may "undulate." This stationary ether, as shown by Young, also afforded a satisfactory explanation of astronomical aberration. But its very success gave rise to a host of new questionsall bearing on the central problem of relative motion of ether and matter. On the other hand, the negativeevidences in favour of the convection-coefficient had also multiplied. Mascart, Hoek, Maxwell and others sought for definite changesin different opticaleffects induced by the motion of the earth relative to the stationaryether. But all such attempts failed to reveal the slightesttrace of any optical disturbance due to the "absolute" velocityof the earthy, thus proving conclusivelythat all tne different optical effects shared in the general compensation arising out of the Fresnelian convection of the excess ether. It must be carefullynoted that the Fresnelian convection -coefficient implicitlasysumes the existence of a fixed ether (Fresnelo)r at least a wholly stagnant medium at sufficiently distant regions (Stokes), with reference to which alone a convection velocitycan have any significance.Thus the convection coefficient implying some type of a stationary or viscous, yet nevertheless "absolute" ether, succeeded in explaining satisfactorily known optical facts down to 1880.
