The new fully revised book is now better than ever, with clearer explanations, more examples and pictures, and comes with the latest research into the ageing process and a restructured and refined chapter on the link between light and God.This is the easiest book ever written on the final great theory of Einstein.What is the link between the electromagnetic and gravitational fields? How does one field generate the other and vice versa? How do we explain gravity and universal gravitation? Do we live in a purely electromagnetic universe? And are we facing the reality of only one fundamental force of nature responsible for all phenomenon in the Universe?Indeed, did Einstein succeed with his work? Is there anything we can apply from his work that could transform society and how we think about the Universe? Will there be new technologies to emerge from this work?You owe it to yourself to find out by reading this unique book


Max Born afirmó que, aunque Albert Einstein no hubiera escrito una sola línea sobre relatividad, habría sido igualmente uno de los científicos más grandes de todos los tiempos. Este libro, escrito de forma accesible por uno de los especialistas más reconocidos en el campo, explora de forma accesible la cuantía y envergadura de las contribuciones científicas de un Einstein no relativista un Einstein, por tanto, casi «desconocido» en terrenos como las fuerzas moleculares, la termoestadística, el efecto fotoeléctrico, el movimiento browniano, la opalescencia, los cuantos de energía, la estructura dual de la radiación o su posición ante la mecánica cuántica; un asunto éste relacionado con las teorías de «variables ocultas» y sus implicaciones. Tras situar cada uno de los hallazgos de Einstein en su contexto vital e histórico, El desconocido Albert Einstein finaliza indagando con lucidez en la polémica sobre la auténtica responsabilidad que pudo tener Mileva Mari, primera esposa de Albert Einstein, en algunas de las principales aportaciones científicas del mito.


In the spring of 1919, two British solar eclipse expeditions confirmed the correctness of general relativity theory and propelled Albert Einstein to instant celebrity. Before this major turning point, the majority of Einstein's writings published in this volume dealt with the clarification of general relativistic problems, such as the status of the metric field, the character of gravitational waves, the problem of energy-momentum conservation, and questions of cosmology, such as the nature and size of the universe and the distribution of matter within it. After his rise to international fame, Einstein's publications changed markedly. He faced an increasing demand for popular articles and lectures on relativity, its development and meaning. He also felt compelled to respond to a host of commentators, ranging from skeptical physicists to philosophers trying to reconcile his revolutionary theory with their views. For the first time, he also responded in print to outspoken anti-relativists, some of them fueled by cultural conservatism and, frequently, anti-Semitism. Einstein used his newly won fame to lend prestige to political causes, especially to the reconciliation among European nations and to Zionism. In the early years of Weimar Germany, Einstein spoke out vigorously for the young republic, emphasizing the rights of the individual. He agonized over the misery of the Central Europeans in the grip of starvation and economic collapse, praised the support of individuals and groups such as the Quakers, and championed the cause of Eastern European Jews. His rejection of assimilation, combined with a fierce defense of the right of Jews to higher education, led Einstein to campaign for the establishment of a university in Palestine, the land which he conceived of as a cultural center for all Jews. Since this supplementary paperback includes only select portions of Volume 7, it is not recommended for purchase without the main volume.


Mileva Maric (Titel, Serbia, 1875-Zúrich, Suiza, 1948) fue la primera esposa de Albert Einstein. Cuando el que sería autor de la teoría de la relatividad temrinó sus estudios, sólo Mileva creyó en él y estuvo a su lado, ayudándole con sus conocimientos matemáticos (superiores a los de él) y físicos, y también con su apoyo, ya que le infundió espíritu de trabajo, constancia y rigor.
