154-631: Klaus Emil Julius Fuchs (29 December 1911 – 28 January 1988) was a German theoretical physicist and atomic spy who supplied information from the American, British, and Canadian Manhattan Project to the Soviet Union during and shortly after World War II . While at the Los Alamos Laboratory , Fuchs was responsible for many significant theoretical calculations relating to the first nuclear weapons and, later, early models of

308-554: A Quaker . Fuchs had an older brother Gerhard, an older sister Elisabeth, and a younger sister, Kristel. The family moved to Eisenach , where Fuchs attended the Martin-Luther Gymnasium , and took his Abitur . At school, Fuchs and his siblings were taunted over his father's unpopular socialist political views, which they came to share. They became known as the "red foxes", Fuchs being the German word for fox. Fuchs

462-527: A hydrogen bomb in 1946 and 1947. Fuchs also stated that "The last time when I handed over information [to Russian authorities] was in February or March 1949". Fuchs was arrested on 2 February 1950, charged with violations of the Official Secrets Act. Nancy Thorndike Greenspan quotes from police notes on a visit between fellow scientist Peierls and Fuchs in detention shortly after the news of

616-435: A mathematical theory , in the sense that the word "theory" has a different meaning in mathematical terms. R i c = k g {\displaystyle \mathrm {Ric} =kg} The equations for an Einstein manifold , used in general relativity to describe the curvature of spacetime A physical theory involves one or more relationships between various measurable quantities. Archimedes realized that

770-652: A revival known as the Erweckung , or Awakening . In 1806, Napoleon's invasion of Germany promoted Rationalism and angered German Lutherans, stirring up a desire among the people to preserve Luther's theology from the Rationalist threat. Those associated with this Awakening held that reason was insufficient and pointed out the importance of emotional religious experiences. Small groups sprang up, often in universities, which devoted themselves to Bible study, reading devotional writings, and revival meetings. Although

924-729: A signed statement, which he then did at the War Office in London. The document included the statement "I was given the chance of admitting it and staying at Harwell or clearing out." Three days later, he also directed a statement more technical in content to Michael Perrin , the deputy controller of atomic energy within the Ministry of Supply. Fuchs told interrogators that the NKGB had acquired an agent in Berkeley, California , who had informed

1078-670: A working hypothesis . Lutheran Bible Translators Theologians Lutheranism is a major branch of Protestantism that identifies primarily with the theology of Martin Luther , the 16th-century German friar and reformer whose efforts to reform the theology and practices of the Catholic Church launched the Reformation in 1517. Lutheranism subsequently became the state religion of many parts of Northern Europe , starting with Prussia in 1525. In 1521,

1232-591: A century of vitality, the Pietist theologians Philipp Jakob Spener and August Hermann Francke warned that orthodoxy had degenerated into meaningless intellectualism and formalism , while orthodox theologians found the emotional and subjective focuses of Pietism to be vulnerable to Rationalist propaganda. In 1688, the Finnish Radical Pietist Lars Ulstadius ran down the main aisle of Turku Cathedral naked while screaming that

1386-404: A certain economy and elegance (compare to mathematical beauty ), a notion sometimes called " Occam's razor " after the 13th-century English philosopher William of Occam (or Ockham), in which the simpler of two theories that describe the same matter just as adequately is preferred (but conceptual simplicity may mean mathematical complexity). They are also more likely to be accepted if they connect

1540-514: A classic. Fuchs was one of the many Los Alamos scientists present at the Trinity test in July 1945. Socially, Fuchs was later judged as someone who kept to himself, and never talked about politics. He was fairly well-liked. He dated grade school teachers Evelyn Kline and Jean Parker, and occasionally served as a babysitter for other scientists. He befriended Richard Feynman . Fuchs and Peierls were

1694-500: A form of protoscience and others are a form of pseudoscience . The falsification of the original theory sometimes leads to reformulation of the theory. "Thought" experiments are situations created in one's mind, asking a question akin to "suppose you are in this situation, assuming such is true, what would follow?". They are usually created to investigate phenomena that are not readily experienced in every-day situations. Famous examples of such thought experiments are Schrödinger's cat ,

1848-766: A good example. For instance: " phenomenologists " might employ ( semi- ) empirical formulas and heuristics to agree with experimental results, often without deep physical understanding . "Modelers" (also called "model-builders") often appear much like phenomenologists, but try to model speculative theories that have certain desirable features (rather than on experimental data), or apply the techniques of mathematical modeling to physics problems. Some attempt to create approximate theories, called effective theories , because fully developed theories may be regarded as unsolvable or too complicated . Other theorists may try to unify , formalise, reinterpret or generalise extant theories, or create completely new ones altogether. Sometimes

2002-487: A great deal of research for his 2019 biography, Trinity , Frank Close confirmed that while MI5 suspected Fuchs for over two years, "it was decrypters at GCHQ who supplied clear proof of his guilt ... not the crack American team that is normally given all the credit", according to a review of the book. Under interrogation by MI5 officer William Skardon at an informal meeting in December 1949, Fuchs initially denied being

2156-808: A major in Soviet Military Intelligence and an experienced agent who had worked with Richard Sorge 's spy ring in the Far East. In late 1943, Fuchs (codename: "Rest"; he became "Charles" in May 1944) transferred along with Peierls to Columbia University , in New York City, to work on gaseous diffusion as a means of uranium enrichment for the Manhattan Project . Although Fuchs was "an asset" of GRU in Britain, his "control"

2310-526: A month. His daughter, Elisabeth, married a fellow communist, Gustav Kittowski, with whom she had a child they named Klaus. Elisabeth and Kittowski were arrested in 1933, and sentenced to 18 months imprisonment but were freed at Christmas. Emil's son, Gerhard, and his wife Karin were arrested in 1934 and spent the next two years in prison. Gerhard, Karin, Elisabeth and Kittowski established a car rental agency in Berlin, which they used to smuggle Jews and opponents of

2464-498: A new branch of mathematics: infinite, orthogonal series . Modern theoretical physics attempts to unify theories and explain phenomena in further attempts to understand the Universe , from the cosmological to the elementary particle scale. Where experimentation cannot be done, theoretical physics still tries to advance through the use of mathematical models. Mainstream theories (sometimes referred to as central theories ) are

2618-489: A permanent resident in the United States in May 1938. In 1936, Kittowski and Elisabeth were arrested again, and the rental cars were impounded. Gerhard and Karin fled to Czechoslovakia . Elisabeth was released and went to live with her father, Emil, while Kittowski, sentenced to six years, later escaped from prison and also made his way to Czechoslovakia. In August 1939, Elisabeth died by suicide by throwing herself from

2772-543: A reform movement beginning in 1830. He also wrote about 1,500 hymns, including God's Word Is Our Great Heritage . In Norway , Hans Nielsen Hauge , a lay street preacher, emphasized spiritual discipline and sparked the Haugean movement, which was followed by the Johnsonian Awakening within the state-church as spearheaded by its namesake, dogmatician and Pietist Gisle Johnson . The Awakening drove

2926-462: A return to the orthodox theologians of the 17th century and opposed modern Bible scholarship. As editor of the periodical Evangelische Kirchenzeitung , he developed it into a major support of Neo-Lutheran revival and used it to attack all forms of theological liberalism and rationalism. Although he received a large amount of slander and ridicule during his forty years at the head of revival, he never gave up his positions. The theological faculty at

3080-492: A rival of orthodoxy but adopted some devotional literature by orthodox theologians, including Arndt, Christian Scriver , and Stephan Prätorius . Rationalist philosophers from France and England had an enormous impact during the 18th century, along with the German Rationalists Christian Wolff , Gottfried Leibniz , and Immanuel Kant . Their work led to an increase in rationalist beliefs, "at

3234-498: A ship floats by displacing its mass of water, Pythagoras understood the relation between the length of a vibrating string and the musical tone it produces. Other examples include entropy as a measure of the uncertainty regarding the positions and motions of unseen particles and the quantum mechanical idea that ( action and) energy are not continuously variable. Theoretical physics consists of several different approaches. In this regard, theoretical particle physics forms

3388-401: A spy and was not detained. According to Nancy Thorndike Greenspan, author of a 2020 book, Atomic Spy: The Dark Lives of Klaus Fuchs , Skardon told Fuchs that if he admitted his earlier espionage activity, he could be permitted to continue to work at Harwell. In October 1949, Fuchs had approached Henry Arnold, the head of security at Harwell, with the news that his father had been given a chair at

3542-454: A theological and historical defence against the historical criticism of the Bible. Dissenting Lutheran pastors were often reprimanded by the government bureaucracy overseeing them, for example, when they tried to correct Rationalist influences in the parish school. As a result of the impact of a local form of rationalism, termed Neology , by the latter half of the 18th century, genuine piety

3696-438: A thermonuclear weapon design the two had collaborated on. Though it was not a viable design, it was the first instance of the idea of radiation implosion being part of a weapon design. Radiation implosion would later become a core part of the successful Teller–Ulam design for thermonuclear weapons, but its importance was not appreciated at the time. Bethe considered Fuchs "one of the most valuable men in my division" and "one of

3850-765: A train to Berlin for a secret KPD meeting, he read a newspaper article on the Reichstag fire . Fuchs correctly assumed that opposition parties would be blamed for the fire, and surreptitiously removed his hammer and sickle lapel pin . Fellow party members urged him to continue his studies in another country. He went into hiding for five months in the apartment of a fellow party member. In August 1933, he attended an anti-fascist conference in Paris chaired by Henri Barbusse , where he met an English couple, Ronald and Jessie Gunn, who invited him to stay with them in Clapton, Somerset . He

4004-725: A train, leaving Emil to raise her young son, Klaus. Fuchs applied to become a British subject in August 1939, but his application had not been processed before the Second World War broke out in Europe in September 1939. There was a classification system for enemy aliens , but Born provided Fuchs with a reference that said that he had been a member of the SPD from 1930 to 1932, and an anti-Nazi. There matters stood until June 1940, when

4158-469: A wide range of phenomena. Testing the consequences of a theory is part of the scientific method . Physical theories can be grouped into three categories: mainstream theories , proposed theories and fringe theories . Theoretical physics began at least 2,300 years ago, under the Pre-socratic philosophy , and continued by Plato and Aristotle , whose views held sway for a millennium. During

4312-643: Is a carrier of the "Word of God", or that only the communion of the Bishop of Rome has been entrusted to interpret the "Word of God". The Reformation in Sweden began with Olaus and Laurentius Petri , brothers who took the Reformation to Sweden after studying in Germany. They led Gustav Vasa , elected king in 1523, to Lutheranism. The pope's refusal to allow the replacement of an archbishop who had supported

4466-497: Is a model of physical events. It is judged by the extent to which its predictions agree with empirical observations. The quality of a physical theory is also judged on its ability to make new predictions which can be verified by new observations. A physical theory differs from a mathematical theorem in that while both are based on some form of axioms , judgment of mathematical applicability is not based on agreement with any experimental results. A physical theory similarly differs from

4620-454: Is being carried out at a place known only as Camp Y. … Simultaneously, the diffusion method is being tried here in the East. … Should the diffusion method prove successful, it will be used as a preliminary step in the separation, with the final work being done by the electronic method. They hope to have the electronic method ready early in 1945 and the diffusion method in July 1945, but (Fuchs) says

4774-444: Is fully aware of what he is doing. … He is a mathematical physicist … most likely a very brilliant man to have such a position at his age (he looks about 30). We took a long walk after dinner. … He is a member of a British mission to the U.S. working under the direct control of the U.S. Army. … The work involves mainly separating the isotopes... and is being done thusly: The electronic method has been developed at Berkeley, California, and

4928-579: Is hard to evaluate whether Fuchs's information had an accelerating effect on the research, or if it even saved much effort, as the Soviets tended to re-do the research results independently anyway. And in many respects, the Soviet programme was not simply a recapitulation of the Manhattan Project: it explored several approaches that were not done during the war, such as the successful development of

5082-603: Is possibly an allusion to Ferdinand II, Holy Roman Emperor , while the dog possibly refers to Peter Canisius . Another figure interpreted as a snail carrying a church tower is possibly a metaphor for the Protestant church. Also on the rock is the number 1599 and a phrase translating as "thus gets in the world". The historical period of Lutheran Orthodoxy is divided into three sections: Early Orthodoxy (1580–1600), High Orthodoxy (1600–1685), and Late Orthodoxy (1685–1730). Lutheran scholasticism developed gradually, especially for

5236-551: Is seen as God's Word because it has the same meaning as the original Hebrew and Greek. A mistranslation is not God's word, and no human authority can invest it with divine authority. Historically, Lutherans understand the Bible to present all doctrines and commands of the Christian faith clearly . In addition, Lutherans believe that God's Word is freely accessible to every reader or hearer of ordinary intelligence, without requiring any special education. A Lutheran must understand

5390-578: Is that the information furnished by him speeded up the production of an A-Bomb by Russia by several years because it permitted them to start on the development of the explosion [sic: explosive] and have this ready by the time the fissionable material was ready. He concluded that the Russian scientists are as good as scientists in England and the United States but there are fewer good scientists in Russia than

5544-651: Is the final authority on all matters of faith. This contrasts with the belief of the Roman Catholic Church, defined at the Council of Trent , which contends that final authority comes from both Scripture and tradition . Unlike Calvinism , Lutheranism retains many of the liturgical practices and sacramental teachings of the pre-Reformation Western Church, with a particular emphasis on the Eucharist , or Lord's Supper, although Eastern Lutheranism uses

5698-649: The Pergolenweg Ehrengrab section of Berlin's Friedrichsfelde Cemetery . He was portrayed by Denis Forest in the 1987 television miniseries Race for the Bomb . Theoretical physicist The advancement of science generally depends on the interplay between experimental studies and theory . In some cases, theoretical physics adheres to standards of mathematical rigour while giving little weight to experiments and observations. For example, while developing special relativity , Albert Einstein

5852-621: The Byzantine Rite . Lutheran theology differs from Reformed theology in Christology , divine grace , the purpose of God's Law , the concept of perseverance of the saints , and predestination , amongst other matters. The name Lutheran originated as a derogatory term used against Luther by German Scholastic theologian Johann Maier von Eck during the Leipzig Debate in July 1519. Eck and other Roman Catholics followed

6006-817: The Church Ordinance , should rest was "The pure word of God, which is the Law and the Gospel". It does not mention the Augsburg Confession . The priests had to understand the Holy Scripture well enough to preach and explain the Gospel and the Epistles to their congregations. The youths were taught from Luther's Small Catechism , available in Danish since 1532. They were taught to expect at

6160-539: The EPR thought experiment , simple illustrations of time dilation , and so on. These usually lead to real experiments designed to verify that the conclusion (and therefore the assumptions) of the thought experiments are correct. The EPR thought experiment led to the Bell inequalities , which were then tested to various degrees of rigor , leading to the acceptance of the current formulation of quantum mechanics and probabilism as

6314-739: The Inner Mission focused on renewing the situation home. Johann Gottfried Herder , superintendent at Weimar and part of the Inner Mission movement, joined with the Romantic movement with his quest to preserve human emotion and experience from Rationalism. Ernst Wilhelm Hengstenberg , though raised Reformed, became convinced of the truth of historic Lutheranism as a young man. He led the Neo-Lutheran Repristination School of theology, which advocated

6468-586: The March 1932 German presidential election , the SPD supported Paul von Hindenburg for President , fearing that a split vote would hand the job to the Nazi Party (NSDAP) candidate, Adolf Hitler . However, when the Communist Party of Germany (KPD) ran its own candidate, Ernst Thälmann , Fuchs offered to speak for him, and was expelled from the SPD. That year Fuchs and all three of his siblings joined

6622-698: The Proceedings of the Royal Society . He also received a Doctorate in Science degree from Edinburgh. Fuchs proudly mailed copies back to his father, Emil, in Germany. In Germany, Emil had been dismissed from his academic post, and, disillusioned with the Lutheran Church's support of the NSDAP, had become a Quaker in 1933. He was arrested for speaking out against the government and was held for

6776-688: The Prussian Union of Churches . The unification of the two branches of German Protestantism sparked the Schism of the Old Lutherans . Many Lutherans, called " Old Lutherans ", chose to leave the state churches despite imprisonment and military force. Some formed independent church bodies, or " free churches ", at home while others left for the United States, Canada and Australia. A similar legislated merger in Silesia prompted thousands to join

6930-642: The Reformed tradition also used that term. To distinguish the two evangelical groups, others began to refer to the two groups as Evangelical Lutheran and Evangelical Reformed . As time passed by, the word Evangelical was dropped. Lutherans themselves began to use the term Lutheran in the middle of the 16th century, in order to distinguish themselves from other groups such as the Anabaptists and Calvinists . In 1597, theologians in Wittenberg defined

7084-572: The Scientific Revolution gathered pace, the concepts of matter , energy, space, time and causality slowly began to acquire the form we know today, and other sciences spun off from the rubric of natural philosophy . Thus began the modern era of theory with the Copernican paradigm shift in astronomy, soon followed by Johannes Kepler 's expressions for planetary orbits, which summarized the meticulous observations of Tycho Brahe ;

7238-683: The Social Democratic Party of Germany (SPD), and the Reichsbanner Schwarz-Rot-Gold , an SPD-allied paramilitary organisation. He was expelled from the SPD in 1932, and joined the Communist Party of Germany (KPD). He went into hiding after the 1933 Reichstag fire and the subsequent persecution of communists in Nazi Germany, and fled to the United Kingdom, where he received his PhD from

7392-738: The University of Bristol under the supervision of Nevill Francis Mott , and his DSc from the University of Edinburgh , where he worked as an assistant to Max Born . After the Second World War broke out in Europe, he was interned in the Isle of Man , and later in Canada. After he returned to Britain in 1941, he became an assistant to Rudolf Peierls , working on " Tube Alloys "—the British atomic bomb project. He began passing information on

7546-545: The University of Erlangen in Bavaria became another force for reform. There, professor Adolf von Harless , though previously an adherent of rationalism and German idealism , made Erlangen a magnet for revival oriented theologians. Termed the Erlangen School of theology, they developed a new version of the Incarnation , which they felt emphasized the humanity of Jesus better than the ecumenical creeds. As theologians, they used both modern historical critical and Hegelian philosophical methods instead of attempting to revive

7700-400: The University of Leipzig in East Germany , and this information became a factor as well. In early January Fuchs was informed that he must resign his position at Harwell because of his father's appointment in East Germany. He was offered help in finding a university post. Meeting with Skardon for a fourth time on 24 January 1950, Fuchs voluntarily confessed that he had shared information with

7854-434: The gas centrifuge method of enrichment. Fuchs's own assessment of the effects of his actions, as reflected in an interview with his Perrin after his arrest, was he thought he could have saved the Soviets "several years" time ("one year at least") because they could have started the development of the weapon design so that it was ready by the time sufficient fissile material became available: He stated that his best estimate

8008-411: The higher critical method. The 2008 U.S. Religious Landscape Survey conducted by the Pew Research Center surveyed 1,926 adults in the United States that self-identified as Lutheran. The study found that 30% believed that the Bible was the Word of God and was to be taken literally word for word. 40% held that the Bible was the Word of God, but was not literally true word for word or were unsure. 23% said

8162-399: The hydrogen bomb . After his conviction in 1950, he served nine years in prison in the United Kingdom, then migrated to East Germany where he resumed his career as a physicist and scientific leader. The son of a Lutheran pastor, Fuchs attended the University of Leipzig , where his father was a professor of theology , and became involved in student politics, joining the student branch of

8316-547: The state religion of numerous states of northern Europe , especially in northern Germany , Scandinavia , and the then- Livonian Order . Lutheran clergy became civil servants and the Lutheran churches became part of the state. Lutheranism spread through all of Scandinavia during the 16th century as the monarchs of Denmark–Norway and Sweden adopted the faith. Through Baltic-German and Swedish rule, Lutheranism also spread into Estonia and Latvia . It also began spreading into Lithuania Proper with practically all members of

8470-411: The two-fluid theory of electricity are two cases in this point. However, an exception to all the above is the wave–particle duality , a theory combining aspects of different, opposing models via the Bohr complementarity principle . Physical theories become accepted if they are able to make correct predictions and no (or few) incorrect ones. The theory should have, at least as a secondary objective,

8624-437: The "Runaway Super" idea, and also found it to be a dead-end. Their own independent reinvention of the Teller–Ulam principle was accomplished through a different approach than in the United States. The Soviet physicist German Goncharov has noted that while Fuchs's early work did not help Soviet efforts towards the hydrogen bomb, it was in retrospect closer to the right approach than any scientists (Soviet or American) recognised at

8778-429: The 19th century. Another important event in the 19th century was the discovery of electromagnetic theory , unifying the previously separate phenomena of electricity, magnetism and light. The pillars of modern physics , and perhaps the most revolutionary theories in the history of physics, have been relativity theory and quantum mechanics . Newtonian mechanics was subsumed under special relativity and Newton's gravity

8932-462: The AB/1 series, which has been closed for access for most human beings". Fuchs was highly regarded as a scientist by the British, who wanted him to return to the United Kingdom to work on Britain's postwar nuclear weapons programme . He returned in August 1946 and became the head of the Theoretical Physics Division at the Atomic Energy Research Establishment at Harwell . From late 1947 to May 1949 he gave Alexander Feklisov , his Soviet case officer,

9086-421: The Americas usually agree to teach in harmony with the entire Lutheran confessions. Some Lutheran church bodies require this pledge to be unconditional because they believe the confessions correctly state what the Bible teaches. Others allow their congregations to do so "insofar as" the confessions are in agreement with the Bible. In addition, Lutherans accept the teachings of the first seven ecumenical councils of

9240-401: The Bible was the written Word of God, and the only infallible guide for faith and practice. He held that every passage of Scripture has one straightforward meaning, the literal sense as interpreted by other Scripture. These teachings were accepted during the orthodox Lutheranism of the 17th century. During the 18th century, Rationalism advocated reason rather than the authority of the Bible as

9394-447: The Bible was written by men and not the Word of God. 7% did not know, were not sure, or had other positions. Although many Lutherans today hold less specific views of inspiration , historically, Lutherans affirm that the Bible does not merely contain the Word of God, but every word of it is, because of plenary, verbal inspiration, the direct, immediate word of God. The Apology of the Augsburg Confession identifies Holy Scripture with

In the latter case, a correspondence principle will be required to recover the previously known result . Sometimes though, advances may proceed along different paths. For example, an essentially correct theory may need some conceptual or factual revisions; atomic theory , first postulated millennia ago (by several thinkers in Greece and India ) and

9856-546: The Elastic Constants of Monovalent Metals" was published in the Proceedings of the Royal Society in 1936. By this time, Mott had a number of German refugees working for him, and lacked positions for them all. He did not think that Fuchs would make much of a teacher, so he arranged a research post for Fuchs, at the University of Edinburgh working under Max Born , who was himself a German refugee. Fuchs published papers with Born on "The Statistical Mechanics of Condensing Systems" and "On Fluctuations in Electromagnetic radiation" in

10010-496: The GDR, Fuchs continued his scientific career and achieved considerable prominence as a leader of research. He became a member of the SED central committee in 1967, and in 1972 was elected to the Academy of Sciences where from 1974 to 1978 he was the head of the research area of physics, nuclear and materials science; he was then appointed deputy director of the Central Institute for Nuclear Physics in Rossendorf, Dresden , where he served until he retired in 1979. From 1984, Fuchs

10164-464: The KPD. Fuchs and his brother Gerhard were active speakers at public meetings, and occasionally attempted to disrupt NSDAP gatherings. At one such gathering, Fuchs was beaten up and thrown into a river. When Hitler became Chancellor of Germany in January 1933, Fuchs decided to leave Kiel, where the NSDAP was particularly strong and he was a well-known KPD member. He enrolled at the Kaiser Wilhelm Institute for Physics in Berlin. On 28 February, while on

In German-ruled Lithuania Minor , however, Lutheranism remained the dominant branch of Christianity. Lutheranism played a crucial role in preserving the Lithuanian language . Since 1520, regular Lutheran services have been held in Copenhagen . Under

With summary of early interrogations ... and details of the scientifical/technical information passed to the Russians". The date of release of this material was not stated. According to an October 2020 book review, author Nancy Thorndike Greenspan "appears to have had access to some of the Fuchs files that have been withheld at Kew, such as

10626-415: The Nazis and winning the war. Fuchs consented to the advice not to raise the question of inducement in his decision to admit guilt. After a trial lasting less than 90 minutes that was based on his confession, Lord Goddard sentenced Fuchs to 14 years' imprisonment , the maximum for espionage . The judge argued that his crime could not have been considered treason (which was a capital crime ), because

10780-408: The Old Lutheran movement. The dispute over ecumenism overshadowed other controversies within German Lutheranism. Despite political meddling in church life, local and national leaders sought to restore and renew Christianity. Neo-Lutheran Johann Konrad Wilhelm Löhe and Old Lutheran free church leader Friedrich August Brünn both sent young men overseas to serve as pastors to German Americans , while

10934-406: The Pedagogical Academy in Kiel , and in the autumn Fuchs transferred to the University of Kiel , which his brother Gerhard and sister Elisabeth also attended. Fuchs continued his studies in mathematics and physics at the university. In October 1931, his mother committed suicide by drinking hydrochloric acid . The family later discovered that his maternal grandmother had also taken her own life. In

11088-558: The Pietist movement's drive to right social wrongs and focus on individual conversion. The Neo-Lutheran call to renewal failed to achieve widespread popular acceptance because it both began and continued with a lofty, idealistic Romanticism that did not connect with an increasingly industrialized and secularized Europe. The work of local leaders resulted in specific areas of vibrant spiritual renewal, but people in Lutheran areas became increasingly distant from church life. Additionally,

11242-509: The Reformation era. The doctrinal positions of Lutheran churches are not uniform because the Book of Concord does not hold the same position in all Lutheran churches. For example, the state churches in Scandinavia consider only the Augsburg Confession as a "summary of the faith" in addition to the three ecumenical creeds. Lutheran pastors, congregations, and church bodies in Germany and

Unlike Catholics, however, they also urged complete agreement with the Book of Concord . The Neo-Lutheran movement managed to slow secularism and counter atheistic Marxism , but it did not fully succeed in Europe. It partly succeeded in continuing

11550-560: The Russians freely acknowledged that Fuchs gave them the fission bomb. Klaus Emil Julius Fuchs was born in Rüsselsheim , Grand Duchy of Hesse , on 29 December 1911, the third of four children of a Lutheran pastor, Emil Fuchs , and his wife Else Wagner. His father served in the army during World War I but later became a pacifist and a socialist , joining the Social Democratic Party of Germany (SPD) in 1921. He eventually became

Fuchs's statements to British and American intelligence agencies were used to implicate Harry Gold , a key witness in the trials of David Greenglass and Julius and Ethel Rosenberg in the United States. Fuchs later stated that he passed detailed information on the project to the Soviet Union through courier Harry Gold in 1945, and further information about Edward Teller 's unworkable "Super" design for

11858-607: The Soviet Union was classed as an ally at the time . On 21 February 1951, he was formally stripped of his British citizenship . The head of the British H-bomb project , Sir William Penney , visited Fuchs in prison in 1952. While imprisoned, Fuchs was friendly with the Irish Republican Army prisoner Seamus Murphy with whom he played chess and helped to escape. Fuchs was released on 23 June 1959 after he had served nine years and four months of his sentence (as

12012-437: The Soviet atomic project, Lavrenti Beria , did not entirely trust either his intelligence sources, nor his own scientists, and so instead used the intelligence information as a third-party check and guide, rather than exploiting it directly. Most of the scientists working on the Soviet bomb project were, accordingly, unaware that they were using any intelligence information as part of their research. Because of these conditions, it

12166-458: The Soviets. According to Nancy Thorndike Greenspan, Skardon's report on their meeting "made no mention of his promise to Fuchs to stay on at Harwell if he confessed", but at the subsequent debriefing it was agreed "to maintain FUCHS in his present state of mind, and for this state of mind to be in no way disturbed". To make it possible to prosecute Fuchs, Skardon proposed that Fuchs be asked to prepare

12320-476: The Soviets: Whether the information Fuchs passed relating to the hydrogen bomb would have been useful is still debated. Most scholars agree with Hans Bethe's 1952 assessment, which concluded that by the time Fuchs left the thermonuclear programme in mid-1946, too little was known about the mechanism of the hydrogen bomb for his information to be useful to the Soviet Union. Fuchs's knowledge and own work

12474-869: The Statistical Method in Nuclear Theory . While interned in Quebec, he joined a communist discussion group led by Hans Kahle . Kahle was a KPD member who had fought in the Spanish Civil War . After fleeing to Britain with his family, Kahle had helped Jürgen Kuczynski organise the KPD in Britain. Kristel arranged for mathematics professor Israel Halperin , the brother-in-law of a friend of hers, Wendell H. Furry , to send Fuchs some magazines, likely scientific journals. Max Born lobbied for his release. On Christmas Day 1940, Fuchs and Kahle were among

12628-649: The Word of God and calls the Holy Spirit the author of the Bible. Because of this, Lutherans confess in the Formula of Concord , "we receive and embrace with our whole heart the prophetic and apostolic Scriptures of the Old and New Testaments as the pure, clear fountain of Israel". The prophetic and apostolic Scriptures are confessed as authentic and written by the prophets and apostles. A correct translation of their writings

12782-581: The acceptance of its teaching. This teaching produces faith and obedience. Holy Scripture is not a dead letter, but rather, the power of the Holy Spirit is inherent in it. Scripture does not compel a mere intellectual assent to its doctrine, resting on logical argumentation, but rather it creates the living agreement of faith. As the Smalcald Articles affirm, "in those things which concern the spoken, outward Word, we must firmly hold that God grants His Spirit or grace to no one, except through or with

12936-407: The accusing party. The divide centered primarily on two points: the proper source of authority in the church , often called the formal principle of the Reformation, and the doctrine of justification , the material principle of Lutheran theology. Lutheranism advocates a doctrine of justification "by Grace alone through faith alone on the basis of Scripture alone", the doctrine that scripture

13090-466: The amount of uranium that it could procure, it is difficult for scholars to counterfactually judge how much time or effort was saved. Prior to the opening up of the Soviet archives in the early 1990s, scholars and analysts tended to assume that the Soviets would have applied any technical intelligence as directly as possible. However historical work after the end of the Cold War revealed that the head of

13244-419: The applications of relativity to problems in astronomy and cosmology respectively . All of these achievements depended on the theoretical physics as a moving force both to suggest experiments and to consolidate results — often by ingenious application of existing mathematics, or, as in the case of Descartes and Newton (with Leibniz ), by inventing new mathematics. Fourier's studies of heat conduction led to

13398-406: The arrest broke. When Peierls asked Fuchs why he had spied, Fuchs answered: "Knowledge of atomic research should not be the private property of any one country but should be shared with the rest of the world for the benefit of mankind." Hans Bethe once said that Fuchs was the only physicist he knew to have truly changed history. Considering that the pace of the Soviet programme was set primarily by

13552-608: The beginning of this Awakening tended heavily toward Romanticism, patriotism , and experience, the emphasis of the Awakening shifted around 1830 to restoring the traditional liturgy, doctrine, and confessions of Lutheranism in the Neo-Lutheran movement. This Awakening swept through all of Scandinavia except Iceland . It developed from both German Neo-Lutheranism and Pietism. Danish pastor and philosopher N. F. S. Grundtvig reshaped church life throughout Denmark through

13706-878: The best theoretical physicists we had." At the request of Norris Bradbury , who had replaced Robert Oppenheimer as director of the Los Alamos Laboratory in October 1945, Fuchs stayed on at the laboratory into 1946 to help with preparations for the Operation Crossroads weapons tests. The US Atomic Energy Act of 1946 (McMahon Act) prohibited the transfer of information on nuclear research to any foreign country, including Britain, without explicit official authority, and Fuchs supplied highly classified U.S. information to nuclear scientists in Britain and to his Soviet contacts. As of 2014, British official files on Fuchs were still being withheld. As of 2020,

13860-514: The body of knowledge of both factual and scientific views and possess a usual scientific quality of the tests of repeatability, consistency with existing well-established science and experimentation. There do exist mainstream theories that are generally accepted theories based solely upon their effects explaining a wide variety of data, although the detection, explanation, and possible composition are subjects of debate. The proposed theories of physics are usually relatively new theories which deal with

14014-692: The clergy. While this effectively granted official sanction to Lutheran ideas, Lutheranism did not become official until 1593. At that time the Uppsala Synod declared Holy Scripture the sole guideline for faith, with four documents accepted as faithful and authoritative explanations of it: the Apostles' Creed , the Nicene Creed , the Athanasian Creed , and the unaltered Augsburg Confession of 1530. Mikael Agricola 's translation of

14168-547: The disgrace of Finnish clergymen would be revealed like his current disgrace. The last famous orthodox Lutheran theologian before the rationalist Aufklärung , or Enlightenment , was David Hollatz . Late orthodox theologian Valentin Ernst Löscher took part in the controversy against Pietism . Medieval mystical traditions continued in the works of Martin Moller , Johann Arndt , and Joachim Lütkemann . Pietism became

14322-401: The end of life: "forgiving of their sins", "to be counted as just", and "the eternal life". Instruction is still similar. The first complete Bible in Danish was based on Martin Luther's translation into German . It was published in 1550 with 3,000 copies printed in the first edition; a second edition was published in 1589. Unlike Catholicism, Lutheranism does not believe that tradition

14476-755: The end of the Thirty Years' War , the compromising spirit seen in Philip Melanchthon rose up again in the Helmstedt School and especially in theology of Georgius Calixtus , causing the syncretistic controversy . Another theological issue that arose was the Crypto-Kenotic controversy. Late orthodoxy was torn by influences from rationalism , philosophy based on reason, and Pietism , a revival movement in Lutheranism. After

14630-635: The expense of faith in God and agreement with the Bible". In 1709, Valentin Ernst Löscher warned that this new Rationalist view of the world fundamentally changed society by drawing into question every aspect of theology. Instead of considering the authority of divine revelation, he explained, Rationalists relied solely on their personal understanding when searching for truth. Johann Melchior Goeze (1717–1786), pastor of St. Catherine's Church in Hamburg , wrote apologetical works against Rationalists, including

14784-570: The final source of knowledge, but most of the laity did not accept this Rationalist position. In the 19th century, a confessional revival re-emphasized the authority of the Scriptures and agreement with the Lutheran Confessions. Today, Lutherans disagree about the inspiration and authority of the Bible. Theological conservatives use the historical-grammatical method of Biblical interpretation, while theological liberals use

14938-638: The first Finnish New Testament was published in 1548. After the death of Martin Luther in 1546, the Schmalkaldic War started out as a conflict between two German Lutheran rulers in 1547. Soon, Holy Roman Imperial forces joined the battle and conquered the members of the Schmalkaldic League , oppressing and exiling many German Lutherans as they enforced the terms of the Augsburg Interim . Religious freedom in some areas

15092-427: The first Chinese atomic bomb , the 596 , which was tested five years later. Three historians of nuclear weapons history, Robert S. Norris, Jeremy Bernstein , and Peter D. Zimmerman , challenged this particular assertion as "unsubstantiated conjecture" and asserted that The Nuclear Express is "an ambitious but deeply flawed book". Fuchs died in Berlin on 28 January 1988. He was cremated and honoured with burial in

15246-509: The first group of internees to board a ship to return to Britain. Fuchs returned to Edinburgh in January, and resumed working for Born. In May 1941, he was approached by Rudolf Peierls of the University of Birmingham to work on the " Tube Alloys " programme – the British atomic bomb research project. Despite wartime restrictions, he became a British subject on 31 July 1942 and signed an Official Secrets Act declaration form. As accommodation

15400-628: The government out of Germany. After Emil was arrested in 1933, his other daughter, Kristel, fled to Zurich, where she studied education and psychology at the University of Zurich . She returned to Berlin in 1934, where she too worked at the car rental agency. In 1936, Emil arranged with Quaker friends in the United States for Kristel to attend Swarthmore College there. She visited her brother, Klaus Fuchs, in England en route to America, where she eventually married an American communist, Robert Heineman, and settled in Cambridge, Massachusetts . She became

15554-640: The growth of foreign missions in Norway to non-Christians to a new height, which has never been reached since. In Sweden, Lars Levi Læstadius began the Laestadian movement that emphasized moral reform. In Finland, a farmer, Paavo Ruotsalainen , began the Finnish Awakening when he took to preaching about repentance and prayer. In 1817, Frederick William III of Prussia ordered the Lutheran and Reformed churches in his territory to unite, forming

15708-416: The highest order, writing Principia Mathematica . In it contained a grand synthesis of the work of Copernicus, Galileo and Kepler; as well as Newton's theories of mechanics and gravitation, which held sway as worldviews until the early 20th century. Simultaneously, progress was also made in optics (in particular colour theory and the ancient science of geometrical optics ), courtesy of Newton, Descartes and

15862-455: The idea of energy (as well as its global conservation) by the inclusion of heat , electricity and magnetism , and then light . The laws of thermodynamics , and most importantly the introduction of the singular concept of entropy began to provide a macroscopic explanation for the properties of matter. Statistical mechanics (followed by statistical physics and Quantum statistical mechanics ) emerged as an offshoot of thermodynamics late in

16016-656: The information he had given could not have been applied so quickly and that the Russians would not have had the engineering design and construction facilities that would be needed to build large production plants in such a short time." The information that Fuchs was able to give the Soviet Union about the Manhattan Project was much more extensive, and much more technically precise, than that available from other, later-discovered atomic spies like David Greenglass or Theodore Hall . According to Fuchs's interview with Perrin after capture, among his other disclosures, he gave

16170-544: The invading forces opposing Gustav Vasa during the Stockholm Bloodbath led to the severing of any official connection between Sweden and the papacy in 1523. Four years later, at the Diet of Västerås  [ sv ] , the king succeeded in forcing the diet to accept his dominion over the national church. The king was given possession of all church properties, as well as the church appointments and approval of

16324-428: The language that scriptures are presented in, and should not be so preoccupied by error so as to prevent understanding. As a result of this, Lutherans do not believe there is a need to wait for any clergy, pope, scholar, or ecumenical council to explain the real meaning of any part of the Bible. Lutherans confess that Scripture is united with the power of the Holy Spirit and with it, not only demands, but also creates

16478-675: The late 1920s. In the aftermath of World War 2, more progress brought much renewed interest in QFT, which had since the early efforts, stagnated. The same period also saw fresh attacks on the problems of superconductivity and phase transitions, as well as the first applications of QFT in the area of theoretical condensed matter. The 1960s and 70s saw the formulation of the Standard model of particle physics using QFT and progress in condensed matter physics (theoretical foundations of superconductivity and critical phenomena , among others ), in parallel to

16632-463: The latter estimate is optimistic. (Fuchs) says there is much being withheld from the British. Even Niels Bohr , who is now in the country incognito as Nicholas Baker, has not been told everything. After the end of the war, in April 1946, he attended a conference at Los Alamos that discussed the possibility of a thermonuclear weapon ; one month later, he filed a patent with John von Neumann , describing

16786-480: The mid-1950s. Fuchs was prosecuted by Sir Hartley Shawcross and was convicted on 1 March 1950 of four counts of breaking the Official Secrets Act by "communicating information to a potential enemy." Fuchs had entered guilty pleas, and his barrister Derek Curtis-Bennett limited his case to a general plea in mitigation on the grounds of his state of mind and desire to assist the Soviets in defeating

16940-572: The middle of the 16th century. These finally ended with the resolution of the issues in the Formula of Concord . Large numbers of politically and religiously influential leaders met together, debated, and resolved these topics on the basis of Scripture, resulting in the Formula, which over 8,000 leaders signed. The Book of Concord replaced earlier, incomplete collections of doctrine , unifying all German Lutherans with identical doctrine and beginning

17094-514: The military attaché at the Soviet Union 's embassy, who worked for the GRU (Russian: Главное Разведывательное Управление ), the Red Army 's foreign military intelligence directorate. After three meetings, Fuchs was teamed up with a courier so he would not have to find excuses to travel to London. She was Ursula Kuczynski (codename: "Sonya"), the sister of Jürgen Kuczynski. She was a German communist,

17248-402: The obscuring of the Gospel teaching of justification by grace through faith alone. The Book of Concord , published in 1580, contains 10 documents which some Lutherans believe are faithful and authoritative explanations of Holy Scripture. Besides the three Ecumenical Creeds , which date to Roman times , the Book of Concord contains seven credal documents articulating Lutheran theology in

17402-613: The only members of the British Mission to Los Alamos who owned cars, and Fuchs lent his Buick to Feynman so Feynman could visit his dying wife in a hospital in Albuquerque . When Fuchs was discovered to be a spy, his former colleagues were shocked. The postwar director of Los Alamos, Norris Bradbury , later said that: Fuchs's main courier in the United States was Harry Gold , a chemist who lived in Philadelphia , but

17556-430: The only presently available sources of divinely revealed knowledge, and the only infallible source of Christian doctrine. Scripture alone is the formal principle of the faith, the final authority for all matters of faith and morals because of its inspiration, authority, clarity, efficacy, and sufficiency. The authority of the Scriptures has been challenged during the history of Lutheranism. Martin Luther taught that

17710-566: The orthodoxy of the 17th century. Friedrich Julius Stahl led the High Church Lutherans . Though raised Jewish, he was baptized as a Christian at the age of 19 through the influence of the Lutheran school he attended. As the leader of a neofeudal Prussian political party, he campaigned for the divine right of kings , the power of the nobility , and episcopal polity for the church. Along with Theodor Kliefoth and August Friedrich Christian Vilmar , he promoted agreement with

17864-465: The other two countries. He stated that he gave the Russians nothing that would speed up the production of plutonium and estimated that if he had given the same data which he gave the Russians to the United States as of the date of his arrival in the United States, he would have speeded the U.S. production of the A-Bomb only slightly. He did pass on to his Russian espionage contact what he learned concerning

18018-561: The people shouted; "We will stand by the holy Gospel, and do not want such bishops anymore". Frederick's son was openly Lutheran, which prevented his election to the throne upon his father's death in 1533. However, following his victory in the civil war that followed, in 1536 he became Christian III and advanced the Reformation in Denmark–Norway . The constitution upon which the Danish Norwegian Church, according to

18172-598: The period of Lutheran Orthodoxy. In lands where Catholicism was the state religion, Lutheranism was officially illegal, although enforcement varied. Until the end of the Counter-Reformation , some Lutherans worshipped secretly, such as at the Hundskirke (which translates as dog church or dog altar), a triangle-shaped Communion rock in a ditch between crosses in Paternion , Austria. The crowned serpent

18326-720: The police arrived and took Fuchs into custody. He was first interned on the Isle of Man and then, in July, he was sent to internment camps in Canada, first on the Plains of Abraham in Quebec City and later at a site near Sherbrooke, Quebec . During his internment in 1940, he continued to work and published four more papers with Born: The Mass Centre in Relativity , Reciprocity, Part II: Scalar Wave Functions , Reciprocity, Part III: Reciprocal Wave Functions and Reciprocity, Part IV: Spinor Wave Functions , and one by himself, On

18480-634: The preceding outward Word". Lutherans are confident that the Bible contains everything that one needs to know in order to obtain salvation and to live a Christian life. There are no deficiencies in Scripture that need to be filled with by tradition, pronouncements of the Pope , new revelations, or present-day development of doctrine . Lutherans understand the Bible as containing two distinct types of content, termed Law and Gospel (or Law and Promises). Properly distinguishing between Law and Gospel prevents

18634-491: The principal theoretical outline for creating a hydrogen bomb and the initial drafts for its development as the work progressed in England and America. Meeting with Feklisov six times, he provided the results of the test at Eniwetok Atoll of uranium and plutonium bombs and the key data on production of uranium-235 . Also in 1947, Fuchs attended a conference of the Combined Policy Committee (CPC), which

18788-419: The process of becoming established and some proposed theories. It can include speculative sciences. This includes physics fields and physical theories presented in accordance with known evidence, and a body of associated predictions have been made according to that theory. Some fringe theories go on to become a widely accepted part of physics. Other fringe theories end up being disproven. Some fringe theories are

18942-419: The production of plutonium during the final period of his work at Los Alamos. He stated that the information furnished by him alone could have speeded up the production of an A-Bomb by Russia by one year at least. He indicated that if the Russians had information on the plutonium process from any other source, the data furnished by him could have been of material assistance on this plutonium phase. Fuchs, however,

19096-548: The project to the Soviet Union through Ursula Kuczynski , codenamed "Sonya", a German communist and a major in Soviet military intelligence who had worked with Richard Sorge 's spy ring in the Far East. In 1943, Fuchs and Peierls went to Columbia University , in New York City, to work on the Manhattan Project. In August 1944, Fuchs joined the Theoretical Physics Division at the Los Alamos Laboratory , working under Hans Bethe . His chief area of expertise

19250-608: The purpose of arguing with the Jesuits , and it was finally established by Johann Gerhard . Abraham Calovius represents the climax of the scholastic paradigm in orthodox Lutheranism. Other orthodox Lutheran theologians include Martin Chemnitz , Aegidius Hunnius , Leonhard Hutter , Nicolaus Hunnius , Jesper Rasmussen Brochmand , Salomo Glassius , Johann Hülsemann , Johann Conrad Dannhauer , Johannes Andreas Quenstedt , Johann Friedrich König , and Johann Wilhelm Baier . Near

19404-534: The reign of Frederick I (1523–1533), Denmark–Norway remained officially Catholic. Although Frederick initially pledged to persecute Lutherans, he soon adopted a policy of protecting Lutheran preachers and reformers, the most significant of which was Hans Tausen . During Frederick's reign, Lutheranism made significant inroads in Denmark. At an open meeting in Copenhagen attended by King Christian III in 1536,

19558-659: The revival movements were divided by philosophical traditions. The Repristination school and Old Lutherans tended towards Kantianism, while the Erlangen school promoted a conservative Hegelian perspective . By 1969, Manfried Kober complained that "unbelief is rampant" even within German Lutheran parishes. Traditionally, Lutherans hold the Scriptures of the Old and New Testaments to be the only divinely inspired books,

19712-703: The rift between the United States and the United Kingdom on matters of atomic energy. Prior to it, the US and UK had been planning to collaborate more fully again on nuclear matters, something that had been put on hold after the passing of the Atomic Energy Act of 1946 . "Whatever hopes had existed for a tightly-integrated programme with the British and Canadians died with the Fuchs revelation", as historians Richard G. Hewlett and Francis Duncan put it. The Anglo-American "Special Relationship" would ultimately be repaired by

19866-607: The rise of medieval universities , the only acknowledged intellectual disciplines were the seven liberal arts of the Trivium like grammar , logic , and rhetoric and of the Quadrivium like arithmetic , geometry , music and astronomy . During the Middle Ages and Renaissance , the concept of experimental science, the counterpoint to theory, began with scholars such as Ibn al-Haytham and Francis Bacon . As

20020-522: The split between Lutherans and the Roman Catholic Church was made public and clear with the Edict of Worms , in which the Diet condemned Luther and officially banned subjects of the Holy Roman Empire from defending or propagating Luther's ideas, facing advocates of Lutheranism with forfeiture of all property. Half of it would be then forfeited to the imperial government and the remaining half to

20174-484: The study of physics which include scientific approaches, means for determining the validity of models and new types of reasoning used to arrive at the theory. However, some proposed theories include theories that have been around for decades and have eluded methods of discovery and testing. Proposed theories can include fringe theories in the process of becoming established (and, sometimes, gaining wider acceptance). Proposed theories usually have not been tested. In addition to

20328-472: The theories like those listed below, there are also different interpretations of quantum mechanics , which may or may not be considered different theories since it is debatable whether they yield different predictions for physical experiments, even in principle. For example, AdS/CFT correspondence , Chern–Simons theory , graviton , magnetic monopole , string theory , theory of everything . Fringe theories include any new area of scientific endeavor in

20482-474: The time. It contained in it the seed of the idea of radiation implosion , which turned out to be of great importance to the final design. In this way, Fuchs's work was a "precursor" of the Teller–Ulam design, but only recognisable as such after the fact, as it was still missing some of the key elements of it and done in the context of a fundamentally different weapon. The revelation of Fuchs's espionage increased

20636-555: The title Lutheran as referring to the true church. Lutheranism has its roots in the work of Martin Luther , who sought to reform the Western Church to what he considered a more biblical foundation. The reaction of the government and church authorities to the international spread of his writings, beginning with the Ninety-five Theses , divided Western Christianity . During the Reformation, Lutheranism became

20790-425: The traditional practice of naming a heresy after its leader, thus labeling all who identified with the theology of Martin Luther as Lutherans. Martin Luther always disliked the term Lutheran , preferring the term evangelical , which was derived from εὐαγγέλιον euangelion , a Greek word meaning "good news", i.e. " Gospel ". The followers of John Calvin , Huldrych Zwingli , and other theologians linked to

20944-539: The vision provided by pure mathematical systems can provide clues to how a physical system might be modeled; e.g., the notion, due to Riemann and others, that space itself might be curved. Theoretical problems that need computational investigation are often the concern of computational physics . Theoretical advances may consist in setting aside old, incorrect paradigms (e.g., aether theory of light propagation, caloric theory of heat, burning consisting of evolving phlogiston , or astronomical bodies revolving around

21098-530: The works of these men (alongside Galileo's) can perhaps be considered to constitute the Scientific Revolution. The great push toward the modern concept of explanation started with Galileo , one of the few physicists who was both a consummate theoretician and a great experimentalist . The analytic geometry and mechanics of Descartes were incorporated into the calculus and mechanics of Isaac Newton , another theoretician/experimentalist of

21252-569: Was concerned with the Lorentz transformation which left Maxwell's equations invariant, but was apparently uninterested in the Michelson–Morley experiment on Earth 's drift through a luminiferous aether . Conversely, Einstein was awarded the Nobel Prize for explaining the photoelectric effect , previously an experimental result lacking a theoretical formulation. A physical theory

21406-551: Was created to facilitate exchange of atomic secrets at the highest levels of governments of the United States, United Kingdom and Canada. Donald Maclean , another Soviet spy, was also in attendance as British co-secretary of CPC. By September 1949, information from the Venona project indicated to GCHQ that Fuchs was a spy, but the British intelligence services were wary of indicating the source of their information. The Soviets had broken off contact with him in February. Fuchs may have been subsequently tipped off by Kim Philby . After

21560-478: Was expelled from the Kaiser Wilhelm Institute in October 1933. Fuchs arrived in England on 24 September 1933. Jessie Gunn was a member of the Wills family, the heirs to Imperial Tobacco and benefactors of the University of Bristol . She arranged for Fuchs to meet Nevill Francis Mott , Bristol's professor of physics, and he agreed to take Fuchs on as a research assistant. Fuchs earned his PhD in physics there in 1937. A paper on "A Quantum Mechanical Calculation of

21714-435: Was found almost solely in small Pietist conventicles. However, some of the laity preserved Lutheran orthodoxy from both Pietism and rationalism by reusing old catechisms, hymnbooks, postils , and devotional writings, including those written by Johann Gerhard , Heinrich Müller and Christian Scriver . Luther scholar Johann Georg Hamann (1730–1788), a layman, became famous for countering Rationalism and striving to advance

21868-422: Was given a kinematic explanation by general relativity . Quantum mechanics led to an understanding of blackbody radiation (which indeed, was an original motivation for the theory) and of anomalies in the specific heats of solids — and finally to an understanding of the internal structures of atoms and molecules . Quantum mechanics soon gave way to the formulation of quantum field theory (QFT), begun in

22022-455: Was head of the scientific councils for energetic basic research and for fundamentals of microelectronics. He received the Patriotic Order of Merit , the Order of Karl Marx and the National Prize of East Germany . In The Nuclear Express: A Political History of the Bomb and Its Proliferation (2009) by Thomas Reed and Daniel Stillman, it is argued that a tutorial Fuchs gave to Qian Sanqiang and other Chinese physicists helped them to develop

22176-450: Was in the context of the original, erroneous "Runaway Super" idea, which was not abandoned until early 1950 in the face of new calculations that showed it would not work. The United States only developed a new, successful approach—the Teller–Ulam design —in early 1951. Fuchs could not give away the secret of the hydrogen bomb, as neither he, nor anyone else, knew it prior to his arrest in 1950. The Soviet hydrogen bomb work also investigated

22330-429: Was left-handed, but was forced to write with his right hand. Fuchs entered the University of Leipzig in 1930, where his father was a professor of theology . He became involved in student politics, joining the student branch of the SPD, a party that his father had joined in 1912, and the Reichsbanner Schwarz-Rot-Gold , the party's paramilitary organisation. His father took up a new position as professor of religion at

22484-417: Was not told how the Soviets would or would not use his information, and though certain questions from his espionage contacts suggested to him that the Soviets had additional sources within the Manhattan Project, he was unaware of their identities and knowledge. He told Perrin that he was himself "extremely surprised" at the speed at which the Soviets developed their own atomic bomb, "as he had been convinced that

22638-405: Was scarce in wartime Birmingham, he stayed with Rudolf and Genia Peierls. Fuchs and Peierls did some important work together, which included a fundamental paper about isotope separation. Soon after, Fuchs contacted Jürgen Kuczynski, who was now teaching at the London School of Economics . Kuczynski put him in contact with Simon Davidovitch Kremer (codename: "Alexander"; 1900-1991), the secretary to

22792-466: Was secured for Lutherans through the Peace of Passau in 1552, and under the legal principle of Cuius regio, eius religio (the religion of the ruler was to dictate the religion of those ruled) and the Declaratio Ferdinandei (limited religious tolerance ) clauses of the Peace of Augsburg in 1555. Religious disputes among the Crypto-Calvinists , Philippists , Sacramentarians , Ubiquitarians , and Gnesio-Lutherans raged within Lutheranism during

22946-510: Was subsequently stripped of his British citizenship . He was released in 1959, after serving nine years, and migrated to the German Democratic Republic (East Germany), where he was elected to the Academy of Sciences and became a member of the Socialist Unity Party of Germany (SED) central committee . He was later appointed deputy director of the Central Institute for Nuclear Physics in Dresden , where he served until his retirement in 1979. Post Cold War declassified information states that

23100-436: Was the problem of implosion , necessary for the development of the plutonium bomb. After the war, he returned to the UK and worked at the Atomic Energy Research Establishment at Harwell as head of the Theoretical Physics Division. In January 1950, Fuchs confessed that he had passed information to the Soviets over a seven-year period beginning in 1942. A British court sentenced him to fourteen years' imprisonment and he

23254-399: Was the problem of imploding the fissionable core of the plutonium bomb. At one point, Fuchs did calculation work that Edward Teller had refused to do because of lack of interest. He was the author of techniques (such as the still-used Fuchs- Nordheim method) for calculating the energy of a fissile assembly that goes highly prompt critical , and his report on blast waves is still considered
