How better to learn the Special Theory of Relativity and the General Theory of Relativity than directly from their creator.---Albert Einstein himselfIn Relativity: The Special and the General Theory, Einstein describes the theories that made him famous, illuminating his case with numerous examples and a smattering of math (nothing more complex than high-school algebra). Einstein's book is not casual reading, but for those who appreciate his work without diving into the arcana of theoretical physics, Relativity will prove a stimulating read. --This text refers to an alternate Paperback edition.

精彩书摘
Albert Einstein's Relativity: The Special and the General Theory (1920) is a cornerstone in the edifice of modern physics. With it the great scientist and humanist took his place beside other great teachers of science. Among the greatest achievements of human thinking, the theories of relativity are commonly regarded as the exclusive domain of highly trained physicists and mathematicians. Disapproving of this segregation as he was, Einstein took it upon himself to explain in this book both theories in their simplest and most down-to-earth form, intending it for "those readers who, from a general scientific and philosophical point of view, are interested in the theory, but who are not conversant with the mathematical apparatus." Indeed, within the vast literature on the philosophy of space and time, Einstein's Relativity shall remain an illuminable and intelligible exposition, highly quotable as one of the most lucid presentations of the subject matter, and a launching pad for any further inquiry on the fascinating features of our universe.Albert Einstein (1879-1955) is one of the icons of our times, requiring almost no introduction. A Nobel laureate, the author of the special and the general theories of relativity, and a key figure in the birth of quantum mechanics, he is widely acclaimed as one of the most creative intellects of human history. The German-Jewish-born "technical-expert-third-class" in the Swiss patent office in Bern originally intended to become a secondary-school teacher - a profession for which he had a natural talent, as readers of Relativity would surely appreciate - but in 1909, having completed an astonishing range of theoreticalphysics publications, written in his spare time without the benefit of close contact with scientific literature or colleagues, he was recognized as a leading scientific thinker and two years later was appointed a full professor at the Karl-Ferdinand University in Prague. A year later he returned to Zurich to begin his work on the general theory of relativity and in 1914 accepted a distinguished research position in the Prussian Academy of Sciences together with a chair (but no teaching duties) at the University of Berlin. He was also offered the directorship of the Kaiser Wilhelm Institute of Physics in Berlin, which was about to be established. After a number of false starts, Einstein published, late in 1915, the definitive version of the general theory of relativity, and in so doing forever changed our views of the cosmos.Einstein was first idolized by the popular press when British eclipse expeditions in 1919 confirmed his predictions on the bending of light rays near the sun. The London Times ran the headline on 7 November 1919: Revolution in science - New theory of the Universe - Newtonian ideas overthrown, and three weeks later printed Einstein's popular exposition on relativity. The exposition became a classic, and Einstein became an overnight sensation, the world's first and greatest scientific superstar. Two years later he received the Nobel Prize for his 1905 work on the photoelectric effect. By then Einstein was internationally known, and when he was offered a post in Princeton in 1932 he moved to the United States, never to return to Germany. His late career was marked by unsuccessful attempts to unify the laws of physics, and by a strong distaste for the fashionable so-called "Copenhagen interpretation" of quantum mechanics. A week before his death, Einstein signed his last letter, written to Bertrand Russell, in which he agreed that his name should go on a manifesto urging all nations to give up nuclear weapons. It is only appropriate that one of his last acts was to argue, as he had done all his life, for international peace. With Einstein's death in 1955 the world had not only lost one of its foremost thinkers but also a humanist fighter for peace and freedom.1905 was a remarkable year for Einstein. Among his articles published that year, the paper "On the Electrodynamics of Moving Bodies" delineated the principles of the special theory of relativity. Shortly thereafter his paper "Does the Inertia of a Body Depend upon its Energy Content?" was published; this paper contained the famous equation E = mc2 stating the equivalence of energy and mass. Both papers propounded a revolutionary operational interpretation of a certain mathematical machinery, devised originally by the Dutch physicist H. Lorentz in order to square Maxwell's theory of electrodynamics with apparently contradictory experimental results. Relying as they did on the postulate of relativity and on the postulate of the constancy of the speed of light in a vacuum, they resulted in a new conception of space and time, the radical features of which were best captured in the dramatic words of Einstein's teacher, the mathematician H. Minkowski (1908): "…space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality."The best way to understand the special theory of relativity (STR) is, according to Einstein himself, to see it as a theory of principle, its two famous principles being the relativity principle (that the laws of nature co-vary with uniformly moving reference frames, or as Bondi (1980) puts it, "that velocity does not matter"), and the light principle (that the speed of light in a vacuum is constant, independent of the speed of the source). Another famous theory of principle is thermodynamics; Einstein used to point to this theory as one of his favorites that inspired his conception of STR. In theories of principle such as thermodynamics or STR one starts from empirically observed general properties of phenomena such as the non-existence of perpetual motion machines, in order to infer general applicable results without making any assumptions on hypothetical constituents of the system at hand. Since the building blocks of these theories are "not hypothetically constructed but empirically discovered," in so doing, says Einstein, one employs "the analytic, not the synthetic method." Lorentz's contraction and dilation theory, along with statistical mechanics and its predecessor the kinetic theory of gases, are, on the other hand, examples of constructive theories. They begin, according to Einstein, with certain hypothetical elements and use these as building blocks in an attempt to construct models of more complex processes.Einstein's "principle" approach to physics in STR differs from the "constructive" approach of Lorentz in two major ways. As the late eminent CERN physicist John S. Bell (1987) notes, there is a difference in style, and a difference in philosophy. The difference in style is that theories of principle, as Relativity: The Special and the General Theory nicely demonstrates, are generally more elegant and concise, while constructive theories are usually complicated and cumbersome. The difference in philosophy is that since the question of which uniformly moving reference frame is really at rest is experimentally undeterminable, Einstein - later to be joined happily by logical positivists such as Schlick and Reichenbach - declares the notions "real rest" and "real motion" as meaningless. For him only the relative motion of the two or more uniformly moving objects is real, hence no reference frame is "specially marked out" (Part II, Chapter XVIII). Lorentz, on the other hand, along with Fitzgerald, Larmor, and Poincaré, preferred the view that there is indeed a state of real rest, defined by the "aether," even though the laws of physics conspire to prevent us from detecting it experimentally. And although Einstein's STR is commonly favored today over Lorentz's conspiracy theory, it is important to note that (1) the facts of physics do not oblige us to accept one philosophy rather than the other, and (2) it is not necessary to accept Lorentz's philosophy to accept, as Einstein himself did, "Lorentzian pedagogy" - that the laws of physics in any one reference frame account for all physical phenomena, including the observations of moving observers - especially when it is often simpler to work in a single frame, rather than hurry after each moving object in turn.The birth of the general theory of relativity was more complicated and agonizing for Einstein, although he referred to the idea that marked its conception, namely the equivalence principle between inertial and gravitational mass (originally connived by Poincaré as a skeptical argument), as "the happiest idea of my life." For a long time Einstein struggled with his famous field equations that constraint of the geometry of spacetime and the distribution of matter on it, and it was only with the help of his school friend the mathematician Marcel Grossman that he finally came to grips with their definite form.The general theory of relativity, although of very little use in building an airplane or solving the energy crisis, is a huge step toward our understanding of nature, but Einstein himself recognized in his late career that the original philosophical goal that motivated its conception was not achieved. STR "eliminated," or more precisely made relational, two Newtonian entities that were regarded as absolute, namely simultaneity and velocity. With the general theory of relativity Einstein hoped to implement Mach's principle and to eliminate another absolute entity, namely acceleration. Einstein saw Mach's principle (Part II, Chapter XXI) as a modern version of "Occam razor": unobservable theoretical entities that do no explanatory work in a physical theory are superfluous, hence should be eliminated from the theory. Newton's concept of absolute space (responsible in Newtonian mechanics for absolute acceleration) was the target of Einstein's attack, but the general theory of relativity, although explaining geometry in terms of gravity and gravity in terms of geometry, did not exorcize the ghost of absolute space. Having reconstructed accelerated motion as inertial motion on geodesics, the theory indeed changed the mean...
历史的回响:聚焦20世纪初的欧洲社会变迁 作者: [此处可填入一位虚构的历史学家或社会观察家的名字,例如:亚历山大·科瓦奇] 字数: 约 1500 字 --- 图书简介: 《历史的回响:聚焦20世纪初的欧洲社会变迁》并非一部关于物理学理论的著作,而是一部深入剖析1900年至1939年间,欧洲大陆在政治、文化、社会结构和日常生活层面经历的剧烈断裂与重塑的宏大叙事。本书旨在描绘一个在“美好年代”的浮华表象下,潜藏着深刻矛盾与不安的欧洲,并追踪这些内在张力如何最终汇集成改变世界格局的洪流。 本书的叙事焦点在于“转变”——一种从19世纪的稳定秩序向20世纪的动荡、不确定性过渡的复杂过程。我们摒弃了将历史视为一系列孤立事件的传统手法,转而采用多维度的交叉分析,力图捕捉那个时代知识分子、工人阶级、新兴中产阶级以及边缘群体的集体经验。 第一部分:旧世界的黄昏与新思潮的涌动 (1900-1914) 本部分首先描绘了“美好年代”的图景——那是一个由镀金时代的财富、维多利亚式道德规范和对科技进步的盲目乐观所构筑的表象。然而,作者敏锐地捕捉到了这光鲜外衣下的裂痕: 权力结构的焦虑: 深入探讨了欧洲各大帝国(德意志、奥匈、沙皇俄国)在民族主义、帝国主义竞争和内部社会阶层固化下面临的结构性压力。我们考察了各国君主制如何试图通过对外扩张来转移国内矛盾,以及随之而来的军备竞赛的逻辑。 城市化的冲击与工人运动的兴起: 聚焦于工业化晚期带来的城市人口爆炸、恶劣的居住条件以及随之而来的社会思潮。详细分析了社会主义、共产主义和无政府主义思潮在欧洲工人阶级中的传播与组织化过程,以及工会与政府和资方之间的激烈博弈。 文化与艺术的革命先声: 这一章是本书的亮点之一。它不侧重于科学领域的突破,而是探讨了艺术、哲学和心理学领域如何开始解构既有的现实观。从布鲁克纳的音乐、马奈的画作到尼采哲学的扩散,再到弗洛伊德对潜意识的挖掘,这些文化地震如何预示着理性主义的退潮,为后来的社会动荡铺设了心理基础。 第二部分:战争的创伤与现代性的确立 (1914-1929) 第一次世界大战是本书分析的核心转折点。作者拒绝将战争简单视为政治失败,而是将其视为一种深刻的社会和精神创伤,彻底改变了欧洲的自我认知。 总体战的社会影响: 考察了战争如何以前所未有的规模动员了整个社会——女性进入工厂、物资配给制度、前线与后方的精神联系。讨论了宣传机器的建立及其对民族主义的强化,以及战争如何瓦解了贵族阶层对军队的传统控制权。 凡尔赛体系的脆弱性: 详细分析了战后条约所带来的领土重划、巨额赔款和民族自决的悖论。书中着重探讨了新生的中欧和东欧国家(如波兰、捷克斯洛伐克)在构建民族认同和稳定民主制度时所面临的巨大挑战。 “迷惘的一代”与文化流亡: 描述了战后一代知识分子和艺术家的普遍疏离感。通过对巴黎、柏林和维也纳等文化中心的考察,展示了爵士乐的传入、达达主义的荒诞和超现实主义的梦境,如何成为对理性逻辑破产的集体抵抗。 第三部分:激进思潮的崛起与民主的衰退 (1929-1939) 本书的最后部分关注大萧条对欧洲政治生态的根本性重塑,以及自由民主制度在经济绝望面前的溃败。 经济崩溃与政治极化: 深入分析了1929年华尔街股灾如何迅速传导至依赖美国贷款的欧洲经济体,特别是德国和奥地利。重点对比了两种应对危机的模式:一是通过国家干预和福利主义的尝试(如罗斯福新政在欧洲的影响),二是通过诉诸极权主义的承诺。 法西斯主义的社会基础: 本书对法西斯主义的分析避免了纯粹的意识形态论述,而是将其置于具体的社会背景中。我们考察了法西斯如何在失去生计的工匠、恐慌的中产阶级和小农群体中获得支持,并强调了其对传统秩序的“重建”承诺如何吸引了那些厌倦了自由主义混乱的人。 文化抵抗与道德困境: 在极权主义阴影下,知识分子和艺术家面临着艰难的选择:流亡、沉默,还是积极反抗?本章探讨了西班牙内战作为欧洲意识形态斗争的预演,以及各国知识界对“集体主义”与“个人自由”之间权衡的痛苦抉择。 结语: 《历史的回响》旨在提醒读者,1939年的战争并非凭空发生,而是20世纪初一系列社会、经济和心理断裂的必然结果。本书试图通过细致入微的社会场景还原,揭示在一个看似坚固的时代框架崩塌时,人类社会所表现出的脆弱性、适应性以及最终走向毁灭的复杂动力。它是一部关于结构性危机如何孕育巨大变革的历史编年史。
