Acclaimed by Einstein himself, this is among the clearest, most readable expositions of relativity theory. It explains the problems Einstein faced, the experiments that led to his theories, and what his findings reveal about the forces that govern the universe. 1957 edition.

Albert Einstein is an icon of the twentieth century. Born in Ulm, Germany, in 1879, he is most famous for his theory of relativity. He also made enormous contributions to quantum mechanics and cosmology, and for his work he was awarded the Nobel Prize in 1921. A self-pronounced pacifist, humanist, and, late in his life, democratic socialist, Einstein was also deeply concerned with the social impact of his discoveries. Much of Einstein's life is shrouded in legend. From popular images and advertisements to various works of theater and fiction, he has come to signify so many things. In Einstein: A Biography, Jürgen Neffe presents a clear and probing portrait of the man behind the myth. Unearthing new documents, including a series of previously unknown letters from Einstein to his sons, which shed new light on his role as a father, Neffe paints a rich portrait of the tumultuous years in which Einstein lived and worked. And with a background in the sciences, he describes and contextualizes Einstein's enormous contributions to our scientific legacy. Einstein, a breakout bestseller in Germany, is sure to be a classic biography of the man and proverbial genius who has been called "the brain of the [twentieth] century."

Creation – Big Bang – Science Fiction or Science Madness The debate between creationism and scientific theories of the origin of the universe has been an ongoing and contentious one. On one side, we have the belief in a divine Creator who is responsible for the creation of the world in six days, as described in the Bible. On the other side, we have scientific theories such as the Big Bang, which posits that the universe began with a massive explosion around 13.8 billion years ago. For those who adhere to the belief in a Creator, the concept of a six-day creation holds immense significance. This belief is rooted in faith and is a fundamental tenet of many religious traditions. The idea that a higher power carefully constructed the universe, day by day, is a source of comfort and meaning for many people. Some may argue that the Big Bang theory is nothing more than science fiction or science madness, dismissing it as a fanciful and unsubstantiated idea.

This book tracks the history of the theory of relativity through Einstein’s life, with in-depth studies of its background as built upon by ideas from earlier scientists. The focus points of Einstein’s theory of relativity include its development throughout his life; the origins of his ideas and his indebtedness to the earlier works of Galileo, Newton, Faraday, Mach and others; the application of the theory to the birth of modern cosmology; and his quest for a unified field theory. Treading a fine line between the popular and technical (but not shying away from the occasional equation), this book explains the entire range of relativity and weaves an up-to-date biography of Einstein throughout. The result is an explanation of the world of relativity, based on an extensive journey into earlier physics and a simultaneous voyage into the mind of Einstein, written for the curious and intelligent reader.

Seit über 20 Jahren ist dies die erste umfassende Einstein-Biographie. Der anerkannte Autor Denis Brian untersucht die private, öffentliche und wissenschaftliche Seite der legendären Persönlichkeit dieses rätselhaften Mannes. Geschickt beleuchtet Brian Einsteins eigenartig-neugierigen Charakter, die Träume und Ereignisse, die den künftigen Wissenschaftler vorangetrieben haben auf seiner unglaublichen Reise zu den Gipfeln des Erfolges und weltweiter Anerkennung. Einsteins Lebenswerk veränderte schließlich die Sichtweise der Wissenschaft von der Welt, angefangen bei seinem ersten Entwurf der revolutionären Relativitätstheorie 1905 bis hin zur Entwicklung der Atombombe (und seiner umstrittenen Position als Gegner des nachfolgenden nuklearen Wettrüstens). Der Autor erforscht Einsteins überwältigendes Erbe in Gesprächen mit vielen Zeitgenossen. Auch lüftet Brian das Geheimnis der Formeln, Theorien und Experimente, damit wir ihre Bedeutung und Tragweite besser verstehen können. Mit Prägnanz und Liebe zum Detail entführt er uns in die Welt, in der Einstein arbeitete, zurückgezogen oder gemeinsam mit anderen; von seinen Assistenten wurde er verehrt und mit anderen Physikern seiner Zeit pflegte er freundschaftliche Beziehungen.

Albert Einstein, world-renowned as a physicist, was also publicly committed to radical political views. Despite the vast literature on Einstein, Einstein and Twentieth- Century Politics is the first comprehensive study of his politics, covering his opinions and campaigns on pacifism, Zionism, control of nuclear weapons, world government, freedom, and racial equality. Most studies look at Einstein in isolation but here he is viewed alongside a 'liberal international' of global intellectuals, including Gandhi, Albert Schweitzer, Bertrand Russell, H.G. Wells, George Bernard Shaw, Romain Rolland, Thomas Mann, and John Dewey. Frequently called upon to join campaigns on great issues of war, peace, and social values, they all knew or corresponded with Einstein. This volume examines how Einstein and comparable intellectuals sought to exert a 'salutary influence', as Einstein put it in a letter to Freud. Close attention is given to the unique qualities Einstein brought to his interventions in political debate. His influence derived in the first instance from his celebrity status as the scientist of genius whose theory of relativity was both incomprehensible to most and seemingly relevant to many aspects of aspects of culture and the cosmos. Einstein's complex and enigmatic personality, which combined intense devotion to privacy and a capacity to perform on the public stage, also contributed to the Einstein myth. Studying Einstein's politics, it is argued here, takes us not only into the mind of Einstein but to the heart of the great public issues of the twentieth century.

THUS SPOKE EINSTEIN on LIFE and LIVING Wisdom of Albert Einstein in the Context Selected, Edited, and Commented by V. Alexander STEFAN Institute for Advanced Physics Studies Stefan University

Einstein shocked the world by revealing that time can be different for different observers. This book offers a possible explanation of why it is so. It offers a never-attempted-before approach to understand the secret of time. As we all know, there is an intimate relationship between time and age of objects. But what is this relationship? The author dives deep into the possible relationships between time and age of objects- animate or inanimate- and, in turn, emerges with a novel concept of time- time is a measurement of age. The book proposes that time is acquired by age, not required for it; and thus, time is an acquired property of objects. The author also proposes that just as length, width and height are the measurements of physical extensions of objects (their three spatial dimensions) and not any independent entities; time too, being the measurement of their age, is not independent of objects. In this sense, time seems to be the fourth dimension of objects instead of space. The book attempts to justify its hypothesis by testing its compatibility with Theory of Relativity. Also discussed is the meaning of the so called passage of time and the arrow of time on the basis of the model of time proposed here. The meaning of the much debated concept of time-travel is thoroughly discussed here and it is proposed that this concept, in the sense that we usually take, is a myth. Even if you can manage to reach your future by overcoming all technological limitations (as we all know, theory of relativity allows it), all your friends will be there with you, witnessing the same future. The only difference will be- your clocks will not agree with those of your friends.
