This book focuses on Albert Einstein and his interactions with, and responses to, various scientists, both famous and lesser-known. It takes as its starting point that the discussions between Einstein and other scientists all represented a contribution to the edifice of general relativity and relativistic cosmology. These scientists with whom Einstein implicitly or explicitly interacted form a complicated web of collaboration, which this study explores, focusing on their implicit and explicit responses to Einstein’s work. This analysis uncovers latent undercurrents, indiscernible to other approaches to tracking the intellectual pathway of Einstein to his general theory of relativity. The interconnections and interactions presented here reveal the central figures who influenced Einstein during this intellectual period. Despite current approaches to history presupposing that the efforts of scientists such as Max Abraham and Gunnar Nordström, which differed from Einstein’s own views, be relegated to the background, this book shows that they all had an impact on the development of Einstein’s theories, stressing the limits of approaches focusing solely on Einstein. As such, General Relativity Conflict and Rivalries proves that the general theory of relativity was not developed as a single, coherent construction by an isolated, brooding individual, but, rather, that it came to fruition through Einstein’s conflicts and interactions with other scientists, and was consolidated by his creative processes during these exchanges.

"This book retraces the emergence of relativity principles in early modern mechanics, documents their constructive use in eighteenth- and nineteenth-century mechanics, optics, and electrodynamics, and gives a well-rooted account of the genesis of special and general relativity in the early twentieth century. As an exercise in long-term history, it demonstrates the connectivity of issues and approaches across several centuries, despite enormous changes in context and culture." -- back cover.

“This gracefully written history of twentieth-century gravity research” brings to life the discoveries and developments that confirmed the theory of relativity (Publishers Weekly, starred review). Albert Einstein did nothing of note on May 29, 1919, yet that is when he became immortal. On that day, astronomer Arthur Eddington and his team observed a solar eclipse and found something extraordinary: gravity bends light, just as Einstein predicted. The finding confirmed the theory of general relativity, fundamentally changing our understanding of space and time. A century later, the Event Horizon Telescope examined the space surrounding Sagittarius A*, the supermassive black hole at the center of the Milky Way, to determine whether Einstein was right on the details. In Gravity’s Century, award-winning science writer Ron Cowen brings to life the incredible scientific journey between these two events and sheds light on their groundbreaking implications. From the development of radio telescopes to the discovery of black holes and quasars, and the still-unresolved place of gravity in quantum theory, Cowen breaks down the physics in clear and approachable language. Gravity’s Century vividly demonstrates how the quest to understand gravity is really the quest to comprehend the universe./

A more critical look at the man known today by most as one of the greatest scientists of all time. A unique and thought-provoking narrative quite at odds with the generally-accepted dogma. How exactly did Einstein rise to become so revered today? This is also the story of Mileva Maric, a little-known woman who just so happened to be Einstein’s first wife. When Einstein presented his famous ‘Annus Mirabilis’ or ‘Wonder Year’ papers in 1905, Mileva was of equal training in the fields of mathematics and physics and indeed, more accomplished than Einstein in many other disciplines. “He seems more an intuitive physicist,” stated Chaim Weizmann, a promoter of Einstein. “He is not an experimental physicist and though he is able to detect fallacies in the conceptions of physical science, he must turn his general outlines of theory over to someone else to work out.” Historians report that Einstein collaborated with other scientists from 1907. In 1905, there was Mileva.

Value theory is a new theory the “value mechanics” that extends w.r.t. quantum mechanics, general relativity, the unified theory of everything, and the string theory into “abstract mechanics” the abstract theory. Thus hypothetically a perfect level when human knowledge becomes ideal to realize teleportation, telepathizing to control dash boards and consoles of digitized machines with the brain. A hypothetical time for AI to reach its peak and perfect robots emergency, time travel possibility, complete understanding of the black/white/worm holes could be engineered as a program to the highest levels and the theory of infinite universe(s) becoming functionally abstract. Great theories of anti-aging would be established, thanks to “time mechanics, light and information mechanics”. Time is flexible and entangles, light photon is sensitive, and information-idea the powerhouse of the universe(s). A time when the black hole could be used to assist the universe instead of fears of it as the most powerful natural machine of destruction. The model of flexibility universality fluidity was hypothesized and tested through various experiments with figures and found to rationally agreeing with value cores and characteristics of a system. The universe(s) is itself a natural intelligent computer and at the same time a printer with time 1. To every intelligent conscious value added on a basic, there is a valuable to be further enhanced: [(v + b u + s)], ... 2. To every abstract universe, there is its exact reality with gravity and energy: [f(n) = 1/(n-1) = 1/(1-n) -n^2 n^3-n^2-1], ... 3.

Nature is made up of boundaries, barriers and gate constrictions in all things, everywhere, and at all levels, and wherever these barriers exist, there is a transition governed by time, or a time machine: [(A) = (t^2/el)+], ...

This book pieces together the jigsaw puzzle of Einstein’s journey to discovering the special theory of relativity. Between 1902 and 1905, Einstein sat in the Patent Office and may have made calculations on old pieces of paper that were once patent drafts. One can imagine Einstein trying to hide from his boss, writing notes on small sheets of paper, and, according to reports, seeing to it that the small sheets of paper on which he was writing would vanish into his desk-drawer as soon as he heard footsteps approaching his door. He probably discarded many pieces of papers and calculations and flung them in the waste paper basket in the Patent Office. The end result was that Einstein published nothing regarding the special theory of relativity prior to 1905. For many years before 1905, he had been intensely concerned with the topic; in fact, he was busily working on the problem for seven or eight years prior to 1905. Unfortunately, there are no surviving notebooks and manuscripts, no notes and papers or other primary sources from this critical period to provide any information about the crucial steps that led Einstein to his great discovery. In May 1905, Henri Poincaré sent three letters to Hendrik Lorentz at the same time that Einstein wrote his famous May 1905 letter to Conrad Habicht, promising him four works, of which the fourth one, Relativity, was a rough draft at that point. In the May 1905 letters to Lorentz, Poincaré presented the basic equations of his 1905 “Dynamics of the Electron”, meaning that, at this point, Poincaré and Einstein both had drafts of papers relating to the principle of relativity. The book discusses Einstein’s and Poincaré’s creativity and the process by which their ideas developed. The book also explores the misunderstandings and paradoxes apparent in the theory of relativity, and unravels the subtleties and creativity of Einstein.
