The Institute for Advanced Study (IAS), located in Princeton, New Jersey, in the United States, is an independent center for theoretical research and intellectual inquiry. It has served as the academic home of internationally preeminent scholars, including J. Robert Oppenheimer, Albert Einstein, Hermann Weyl, John von Neumann, and Kurt Gödel, after they immigrated to the United States.

It was founded in 1930 by American educator Abraham Flexner, together with philanthropists Louis Bamberger and Caroline Bamberger Fuld. Although it is close to and collaborates with Princeton University, Rutgers University, and other nearby institutions, it is independent and does not charge tuition or fees.

Flexner's guiding principle in founding the institute was the pursuit of knowledge for its own sake. The faculty have no classes to teach. There are no degree programs or experimental facilities at the institute. Research is never contracted or directed. It is left to each individual researcher to pursue their own goals. Established during the rise of fascism in Europe, the institute played a key role in the transfer of intellectual capital from Europe to America. It quickly earned its reputation as the pinnacle of academic and scientific life—a reputation it has retained.

The institute consists of four schools: Historical Studies, Mathematics, Natural Sciences, and Social Sciences. The institute also has a program in theoretical biology.

It is supported entirely by endowments, grants, and gifts. It is one of eight American mathematics institutes funded by the National Science Foundation. It is the model for the other eight members of the consortium Some Institutes for Advanced Study.

History

Founding

The institute was founded in 1930 by Abraham Flexner, together with philanthropists Louis Bamberger and Caroline Bamberger Fuld. Flexner was interested in education generally and as early as 1890 he had founded an experimental school which had no formal curriculum, exams, or grades. It was a great success at preparing students for prestigious colleges and this same philosophy would later guide him in the founding of the Institute for Advanced Study. Flexner's study of medical schools, the 1910 Flexner Report, played a major role in the reform of medical education. Flexner had studied European schools such as Heidelberg University, All Souls College, Oxford, and the Collège de France–and he wanted to establish a similar advanced research center in the United States.

In his autobiography Abraham Flexner reports a phone call which he received in the fall of 1929 from representatives of the Bamberger siblings that led to their partnership and the eventual founding of the IAS:

I was working quietly one day when the telephone rang and I was asked to see two gentlemen who wished to discuss with me the possible uses to which a considerable sum of money might be placed. At our interview, I informed them that my competency was limited to the education field and that in this field it seemed to me that the time was ripe for the creation in America of an institute in the field of general scholarship and science, resembling the Rockefeller Institute in the field of medicine—developed by my brother Simon—not a graduate school, training men in the known and to some extent in methods of research, but an institute where everyone—faculty and members—took for granted what was known and published, and in their individual ways, endeavored to advance the frontiers of knowledge.

The Bamberger siblings wanted to use the proceeds from the sale of their Bamberger’s department store in Newark, New Jersey, to fund a dental school as an expression of gratitude to the state of New Jersey. Flexner convinced them to put their money in the service of more abstract research. (There was a brush with near-disaster when the Bambergers pulled their money out of the market just before the Crash of 1929.) The eminent topologist Oswald Veblen at Princeton University, who had long been trying to found a high-level research institute in mathematics, urged Flexner to locate the new institute near Princeton where it would be close to an existing center of learning and a world-class library. In 1932 Veblen resigned from Princeton and became the first professor in the new Institute for Advanced Study. He selected most of the original faculty and also helped the institute acquire land in Princeton for both the original facility and future expansion.

Flexner and Veblen set out to recruit the best mathematicians and physicists they could find. The rise of fascism and the associated anti-semitism forced many prominent mathematicians to flee Europe and some, such as Einstein and Hermann Weyl (whose wife was Jewish), found a home at the new institute. Weyl as a condition of accepting insisted that the institute also appoint the thirty-year-old Austrian-Hungarian polymath John von Neumann. Indeed, the IAS became the key lifeline for scholars fleeing Europe. Einstein was Flexner's first coup and shortly after that he was followed by Veblen's brilliant student James Alexander and the wunderkind of logic Kurt Gödel. Flexner was fortunate in the luminaries he directly recruited but also in the people that they brought along with them. Thus, by 1934 the fledgeling institute was led by six of the most prominent mathematicians in the world. In 1935 quantum physics pioneer Wolfgang Pauli became a faculty member. With the opening of the Institute for Advanced Study, Princeton replaced Göttingen as the leading center for mathematics in the twentieth century.

Early years

For the six years from its opening in 1933, until Fuld Hall was finished and opened in 1939, the institute was housed within Princeton University—in Fine Hall, which housed Princeton's mathematics department. Princeton University's science departments are less than two miles away and informal ties and collaboration between the two institutions occurred from the beginning. This helped start an incorrect impression that it was part of the University, one that has never been completely eradicated.

On June 4, 1930, the Bambergers wrote as follows to the institute's trustees:

It is fundamental in our purpose, and our express desire, that in the appointments to the staff and faculty, as well as in the admission of workers and students, no account shall be taken, directly or indirectly, of race, religion, or sex. We feel strongly that the spirit characteristic of America at its noblest, above all the pursuit of higher learning, cannot admit of any conditions as to personnel other than those designed to promote the objects for which this institution is established, and particularly with no regard whatever to accidents of race, creed, or sex.

Bamberger's policy did not prevent racial discrimination by Princeton. When African-American mathematician William S. Claytor applied to the IAS in 1937, Princeton University said they "would not permit any colored person to go to the Institute for Advanced Study." It was not until 1939, when the institute had moved into its own building, that Veblen was able to offer Claytor a position; but this time Claytor turned it down on principle.

Flexner had successfully assembled a faculty of unrivaled prestige in the School of Mathematics which officially opened in 1933. He sought to equal this success in the founding of schools of economics and humanities but this proved to be more difficult. The School of Humanistic Studies and the School of Economics and Politics were established in 1935. All three schools along with the office of the Director moved into the newly built Fuld Hall in 1939. (Ultimately the schools of Humanistic Studies and Economics and Politics were merged into the present day School of Historical Studies established in 1949.) In the beginning, the School of Mathematics included physicists as well as mathematicians. A separate School of Natural Sciences was not established until 1966. The School of Social Science was founded in 1973.

Mission

In a 1939 essay Flexner emphasized how James Clerk Maxwell, driven only by a desire to know, did abstruse calculations in the field of magnetism and electricity and that these investigations led in a direct line to the entire electrical development of modern times. Citing Maxwell and other theoretical scientists such as Gauss, Faraday, Ehrlich and Einstein, Flexner said, "Throughout the whole history of science most of the really great discoveries which have ultimately proved to be beneficial to mankind have been made by men and women who were driven not by the desire to be useful but merely the desire to satisfy their curiosity."

Fuld Hall

The IAS Bluebook says:

The Institute for Advanced Study is one of the few institutions in the world where the pursuit of knowledge for its own sake is the ultimate raison d'être. Speculative research, the kind that is fundamental to the advancement of human understanding of the world of nature and of humanity, is not a product that can be made to order. Rather, like artistic creativity, it benefits from a special environment.

This was the belief to which Flexner clung passionately, and which continues to inspire the institute today.

Impact

Institute for Advanced Study campus

From the day it opened the IAS had a major impact on mathematics, physics, economic theory, and world affairs. In mathematics forty-two out of sixty-one Fields Medalists have been affiliated with the institute. Thirty-four Nobel Laureates have been working at the IAS. Of the sixteen Abel Prizes awarded since the establishment of that award in 2003, nine were garnered by Institute professors or visiting scholars. Of the fifty-six Cole Prizes awarded since the establishment of that award in 1928, thirty-nine have gone to scholars associated with the IAS at some point in their career. IAS people have won 20 Wolf Prizes in mathematics and physics. Its more than 6,000 former members hold positions of intellectual and scientific leadership throughout the academic world.

Pioneering work on the theory of the stored-program computer as laid down by Alan Turing was done at the IAS by John von Neumann, and the IAS machine built in the basement of the Fuld Hall from 1942 to 1951 under von Neumann's direction introduced the basic architecture of all modern digital computers. The IAS is the leading center of research in string theory and its generalization M-theory introduced by Edward Witten at the IAS in 1995. The Langlands program, a far-reaching approach which unites parts of geometry, mathematical analysis, and number theory was introduced by Robert Langlands, the mathematician who now occupies Albert Einstein's old office at the institute. Langlands was inspired by the work of Hermann Weyl, André Weil, and Harish-Chandra, all scholars with wide-ranging ties to the institute, and the IAS maintains the key repository for the papers of Langlands and the Langlands program. The IAS is a main center of research for homotopy type theory, a modern approach to the foundations of mathematics which is not based on classical set theory. A special year organized by Institute professor Vladimir Voevodsky and others resulted in a benchmark book in the subject which was published by the institute in 2013.

The institute is or has been the academic home of many of the best minds of their generation. Among them are James Waddell Alexander II, Michael Atiyah, Enrico Bombieri, Shiing-Shen Chern, Pierre Deligne, Freeman J. Dyson, Albert Einstein, Clifford Geertz, Kurt Gödel, Albert Hirschman, George F. Kennan, Tsung-Dao Lee, Avishai Margalit, J. Robert Oppenheimer, Erwin Panofsky, Atle Selberg, John von Neumann, André Weil, Hermann Weyl, Frank Wilczek, Edward Witten, Chen-Ning Yang and Shing-Tung Yau.

Special Year Programs

Flexner's vision of the kind of results that can emerge in an institution devoted to the pursuit of knowledge for its own sake is illustrated by the "Special Year" programs sponsored by the IAS School of Mathematics. For example, in 2012–13 researchers at the IAS school of mathematics held A Special Year on Univalent Foundations of Mathematics. Intuitionistic type theory was created by the Swedish logician Per Martin-Löf's in 1972 to serve as an alternative to set theory as a foundation for mathematics. The special year brought together researchers in topology, computer science, category theory, and mathematical logic with the goal of formalizing and extending this theory of foundations. The program was organized by Steve Awodey, Thierry Coquand and Vladimir Voevodsky, and resulted in a book being published in homotopy type theory. The authors—more than 30 researchers ultimately contributed to the project—noted the essential contribution of the IAS saying,

Special thanks are due to the Institute for Advanced Study, without which this book would obviously never have come to be. It proved to be an ideal setting for the creation of this new branch of mathematics: stimulating, congenial, and supportive. May some trace of this unique atmosphere linger in the pages of this book, and in the future development of this new field of study.

— The Univalent Foundations Program, Institute for Advanced Study Princeton, April 2013

One of the researchers, Andrej Bauer said,

We are a group of two dozen mathematicians who wrote a 600 page book in less than half a year. This is quite amazing, since mathematicians do not normally work together in large groups. But more importantly, the spirit of collaboration that pervaded our group at the Institute for Advanced Study was truly amazing. We did not fragment. We talked, shared ideas, explained things to each other, and completely forgot who did what.

— Andrej Bauer, Mathematics and Computation, June 20, 2013

The book, informally known as The HoTT book, is freely available online.

Criticism

Richard Feynman argued that the IAS does not offer real activity or challenge:

When I was at Princeton in the 1940s I could see what happened to those great minds at the Institute for Advanced Study, who had been specially selected for their tremendous brains and were now given this opportunity to sit in this lovely house by the woods there, with no classes to teach, with no obligations whatsoever. These poor bastards could now sit and think clearly all by themselves, OK? So they don't get any ideas for a while: They have every opportunity to do something, and they're not getting any ideas. I believe that in a situation like this a kind of guilt or depression worms inside of you, and you begin to worry about not getting any ideas. And nothing happens. Still no ideas come. Nothing happens because there's not enough real activity and challenge: You're not in contact with the experimental guys. You don't have to think how to answer questions from the students. Nothing!

— Richard Feynman

Other Institutes for Advanced Study

The IAS in Princeton is widely recognized as the world's first Institute for Advanced Study. Despite later imitators of the institute's model, it took years before any similar institutions were founded. The Center for Advanced Study in the Behavioral Sciences at Stanford was the first such spinoff in 1954. This was followed by the National Humanities Center founded in North Carolina in 1978. These two institutions eventually became the core of a consortium known as Some Institutes for Advanced Study (SIAS). The SIAS consortium includes the original institute in Princeton and nine other institutes founded explicitly to emulate the model of the original IAS. These ten Institutes for Advanced Study are:

In recent years there have been other institutes loosely based on the Princeton original, in some cases established with help from IAS professors. In 1997 IAS professor Chen-Ning Yang helped the Chinese set up the Institute for Advanced Study at Tsinghua University in Beijing. The Freiburg Institute for Advanced Studies in Freiburg, Germany was founded in 2007, with IAS director at the time Peter Goddard giving the inaugural address. Princeton IAS professors André Weil and Armand Borel helped to establish close contacts with the Ramanujan Institute for Advanced Study in Mathematics, founded in 1967 as part of the University of Madras in India.

The prestigious Institut des Hautes Études Scientifiques (IHÉS) founded in 1958 just south of Paris is universally acknowledged to be the French counterpart of the IAS in Princeton. Princeton Institute director Robert Oppenheimer had a close relationship with IHÉS founder Léon Motchane and played a major role in helping to get it established.

Neither the Princeton IAS nor SIAS is connected with, and should not be confused with, the Consortium of Institutes of Advanced Studies which comprises some twenty research institutes located throughout Great Britain and Ireland. The name Institute for Advanced Study, along with the acronym IAS, is also used by various other independent institutions throughout the world, some having little to do with the Princeton model. See Institute for Advanced Study (disambiguation) for a complete list.

Directors, faculty and members

At any given time, the IAS has a faculty consisting of twenty-eight eminent academics who are appointed for life. Although the faculty do not teach classes (because there are none), they often do give lectures at their own initiative and have the title Professor along with the prestige associated with that title. Furthermore, they direct research and serve as the nucleus of a larger and generally younger group of scholars, whom they have the power to select and invite. Each year fellowships are awarded to about 190 visiting members from over 100 universities and research institutions who come to the institute for periods from one term to a few years. Individuals must apply to become members of the institute, and each of the schools has its own application procedures and deadlines.

Campus, Lands, Olden Farm and Olden Manor

The IAS owns over 600 acres of land, most of which was acquired between 1936 and 1945. Since 1997 the Institute has preserved 589 acres of woods, wetlands, and farmland. By 1936, for total of $290,000, the founding trustees of the IAS had purchased 256 acres, including the two-hundred-acre Olden Farm with Olden Manor, which was the former home of William Olden. Olden Manor, with its extensive gardens, has been, since 1940, the residence of the institute's Director.

Olden Manor is a substantial dwelling owned and maintained by the Institute and located on its main campus on Olden Lane in Princeton Township. It is the principal residence of the Director and his family, to whom it is furnished rent-free and as a term of his employment. It is also used by the Director, on behalf of the Institute, for official entertainment and for numerous faculty and trustees' meetings and conferences.

Atomic Age

From Wikipedia, the free encyclopedia

An early nuclear power plant that used atomic energy to generate electricity

The Atomic Age, also known as the Atomic Era, is the period of history following the detonation of the first nuclear weapon, The Gadget at the Trinity test in New Mexico, on July 16, 1945, during World War II. Although nuclear chain reactions had been hypothesized in 1933 and the first artificial self-sustaining nuclear chain reaction (Chicago Pile-1) had taken place in December 1942, the Trinity test and the ensuing bombings of Hiroshima and Nagasaki that ended World War II represented the first large-scale use of nuclear technology and ushered in profound changes in sociopolitical thinking and the course of technological development.

While atomic power was promoted for a time as the epitome of progress and modernity, entering into the nuclear power era also entailed frightful implications of nuclear warfare, the Cold War, mutual assured destruction, nuclear proliferation, the risk of nuclear disaster (potentially as extreme as anthropogenic global nuclear winter), as well as beneficial civilian applications in nuclear medicine. It is no easy matter to fully segregate peaceful uses of nuclear technology from military or terrorist uses (such as the fabrication of dirty bombs from radioactive waste), which complicated the development of a global nuclear-power export industry right from the outset.

In 1973, concerning a flourishing nuclear power industry, the United States Atomic Energy Commission predicted that, by the turn of the 21st century, one thousand reactors would be producing electricity for homes and businesses across the U.S. However, the "nuclear dream" fell far short of what was promised because nuclear technology produced a range of social problems, from the nuclear arms race to nuclear meltdowns, and the unresolved difficulties of bomb plant cleanup and civilian plant waste disposal and decommissioning. Since 1973, reactor orders declined sharply as electricity demand fell and construction costs rose. Many orders and partially completed plants were cancelled.

By the late 1970s, nuclear power had suffered a remarkable international destabilization, as it was faced with economic difficulties and widespread public opposition, coming to a head with the Three Mile Island accident in 1979, and the Chernobyl disaster in 1986, both of which adversely affected the nuclear power industry for many decades.

Early years

In 1901, Frederick Soddy and Ernest Rutherford discovered that radioactivity was part of the process by which atoms changed from one kind to another, involving the release of energy. Soddy wrote in popular magazines that radioactivity was a potentially "inexhaustible" source of energy, and offered a vision of an atomic future where it would be possible to "transform a desert continent, thaw the frozen poles, and make the whole earth one smiling Garden of Eden." The promise of an "atomic age," with nuclear energy as the global, utopian technology for the satisfaction of human needs, has been a recurring theme ever since. But "Soddy also saw that atomic energy could possibly be used to create terrible new weapons".

The concept of a nuclear chain reaction was hypothesized in 1933, shortly after Chadwick's discovery of the neutron. Only a few years later, in December 1938 nuclear fission was discovered by Otto Hahn and his assistant Fritz Strassmann. Hahn understood that a "burst" of the atomic nuclei had occurred. Lise Meitner and Otto Frisch gave a full theoretical interpretation and named the process "nuclear fission". The first artificial self-sustaining nuclear chain reaction (Chicago Pile-1, or CP-1) took place in December 1942 under the leadership of Enrico Fermi.

In 1945, the pocketbook The Atomic Age heralded the untapped atomic power in everyday objects and depicted a future where fossil fuels would go unused. One science writer, David Dietz, wrote that instead of filling the gas tank of your car two or three times a week, you will travel for a year on a pellet of atomic energy the size of a vitamin pill. Glenn T. Seaborg, who chaired the Atomic Energy Commission, wrote "there will be nuclear powered earth-to-moon shuttles, nuclear powered artificial hearts, plutonium heated swimming pools for SCUBA divers, and much more".

World War II

The phrase Atomic Age was coined by William L. Laurence, a journalist with The New York Times, who became the official journalist for the Manhattan Project which developed the first nuclear weapons. He witnessed both the Trinity test and the bombing of Nagasaki and went on to write a series of articles extolling the virtues of the new weapon. His reporting before and after the bombings helped to spur public awareness of the potential of nuclear technology and in part motivated development of the technology in the U.S. and in the Soviet Union. The Soviet Union would go on to test its first nuclear weapon in 1949.

In 1949, U.S. Atomic Energy Commission chairman, David Lilienthal stated that "atomic energy is not simply a search for new energy, but more significantly a beginning of human history in which faith in knowledge can vitalize man's whole life".

1950s

This view of downtown Las Vegas shows a mushroom cloud in the background. Scenes such as this were typical during the 1950s. From 1951 to 1962 the government conducted 100 atmospheric tests at the nearby Nevada Test Site.

The phrase gained popularity as a feeling of nuclear optimism emerged in the 1950s in which it was believed that all power generators in the future would be atomic in nature. The atomic bomb would render all conventional explosives obsolete and nuclear power plants would do the same for power sources such as coal and oil. There was a general feeling that everything would use a nuclear power source of some sort, in a positive and productive way, from irradiating food to preserve it, to the development of nuclear medicine. There would be an age of peace and plenty in which atomic energy would "provide the power needed to desalinate water for the thirsty, irrigate the deserts for the hungry, and fuel interstellar travel deep into outer space". This use would render the Atomic Age as significant a step in technological progress as the first smelting of bronze, of iron, or the commencement of the Industrial Revolution.

This included even cars, leading Ford to display the Ford Nucleon concept car to the public in 1958. There was also the promise of golf balls which could always be found and nuclear-powered aircraft, which the U.S. federal government even spent US$1.5 billion researching. Nuclear policymaking became almost a collective technocratic fantasy, or at least was driven by fantasy:

The very idea of splitting the atom had an almost magical grip on the imaginations of inventors and policymakers. As soon as someone said—in an even mildly credible way—that these things could be done, then people quickly convinced themselves ... that they would be done.

In the US, military planners "believed that demonstrating the civilian applications of the atom would also affirm the American system of private enterprise, showcase the expertise of scientists, increase personal living standards, and defend the democratic lifestyle against communism".

Some media reports predicted that thanks to the giant nuclear power stations of the near future electricity would soon become much cheaper and that electricity meters would be removed, because power would be "too cheap to meter."

When the Shippingport reactor went online in 1957 it produced electricity at a cost roughly ten times that of coal-fired generation. Scientists at the AEC's own Brookhaven Laboratory "wrote a 1958 report describing accident scenarios in which 3,000 people would die immediately, with another 40,000 injured".

However Shippingport was an experimental reactor using highly enriched uranium (unlike most power reactors) and originally intended for a (cancelled) nuclear-powered aircraft carrier. Kenneth Nichols was a consultant for the Connecticut Yankee and Yankee Rowe nuclear power stations wrote that while considered "experimental" and not expected to be competitive with coal and oil, they "became competitive because of inflation... and the large increase in price of coal and oil." He wrote that for nuclear power stations the capital cost is the major cost factor over the life of the plant, hence "antinukes" try to increase costs and building time with changing regulations and lengthy hearings, so that "it takes almost twice as long to build a (U.S.-designed boiling-water or pressurised water) atomic power plant in the United States as in France, Japan, Taiwan or South Korea." French pressurised-water nuclear plants produce 60% of their electric power, and have proven to be much cheaper than oil or coal.

Fear of possible atomic attack from the Soviet Union caused U.S. school children to participate in "duck and cover" civil defense drills.

Atomic City

During the 1950s, Las Vegas, Nevada, earned the nickname "Atomic City" for becoming a hotspot where tourists would gather to watch above-ground nuclear weapons tests taking place at Nevada Test Site. Following the detonation of Able, one of the first atomic bombs dropped at the Nevada Test Site, the Las Vegas Chamber of Commerce began advertising the tests as an entertainment spectacle to tourists.

The detonations proved popular and casinos throughout the city capitalised on the tests by advertising hotel rooms or rooftops which offered views of the testing site or by planning "Dawn Bomb Parties" where people would come together to celebrate the detonations. Most parties started at midnight and musicians would perform at the venues until 4:00 a.m. when the party would briefly stop so guests could silently watch the detonation. Some casinos capitalised on the tests further by creating so called "atomic cocktails", a mixture of vodka, cognac, sherry and champagne.

Meanwhile, groups of tourists would drive out into the desert with family or friends to watch the detonations.

Despite the health risks associated with nuclear fallout, tourists and viewers were told to simply "shower". Later on, however, anyone who had worked at the testing site or lived in areas exposed to nuclear fallout fell ill and had higher chances of developing cancer or suffering pre-mature deaths.

1960s

By exploiting the peaceful uses of the "friendly atom" in medical applications, earth removal and, subsequently, in nuclear power plants, the nuclear industry and government sought to allay public fears about nuclear technology and promote the acceptance of nuclear weapons. At the peak of the Atomic Age, the United States government initiated Operation Plowshare, involving "peaceful nuclear explosions". The United States Atomic Energy Commission chairman announced that the Plowshares project was intended to "highlight the peaceful applications of nuclear explosive devices and thereby create a climate of world opinion that is more favorable to weapons development and tests".

Project Plowshare "was named directly from the Bible itself, specifically Micah 4:3, which states that God will beat swords into ploughshares, and spears into pruning hooks, so that no country could lift up weapons against another". Proposed uses included widening the Panama Canal, constructing a new sea-level waterway through Nicaragua nicknamed the Pan-Atomic Canal, cutting paths through mountainous areas for highways, and connecting inland river systems. Other proposals involved blasting caverns for water, natural gas, and petroleum storage. It was proposed to plant underground atomic bombs to extract shale oil in eastern Utah and western Colorado. Serious consideration was also given to using these explosives for various mining operations. One proposal suggested using nuclear blasts to connect underground aquifers in Arizona. Another plan involved surface blasting on the western slope of California's Sacramento Valley for a water transport project. However, there were many negative impacts from Project Plowshare's 27 nuclear explosions. Consequences included blighted land, relocated communities, tritium-contaminated water, radioactivity, and fallout from debris being hurled high into the atmosphere. These were ignored and downplayed until the program was terminated in 1977, due in large part to public opposition, after $770 million had been spent on the project.

In the Thunderbirds TV series, a set of vehicles was presented that were imagined to be completely nuclear, as shown in cutaways presented in their comic-books.

The term "atomic age" was initially used in a positive, futuristic sense, but by the 1960s the threats posed by nuclear weapons had begun to edge out nuclear power as the dominant motif of the atom.

1970 to 2000

A photograph taken in the abandoned city of Pripyat. The Chernobyl nuclear power plant can be seen on the horizon.

French advocates of nuclear power developed an aesthetic vision of nuclear technology as art to bolster support for the technology. Leclerq compares the nuclear cooling tower to some of the grandest architectural monuments of western culture:

The age in which we live has, for the public, been marked by the nuclear engineer and the gigantic edifices he has created. For builders and visitors alike, nuclear power plants will be considered the cathedrals of the 20th century. Their syncretism mingles the conscious and the unconscious, religious fulfilment and industrial achievement, the limitations of uses of materials and boundless artistic inspiration, utopia come true and the continued search for harmony.

In 1973, the United States Atomic Energy Commission predicted that, by the turn of the 21st century, one thousand reactors would be producing electricity for homes and businesses across the USA. But after 1973, reactor orders declined sharply as electricity demand fell and construction costs rose. Many orders and partially completed plants were cancelled.

Nuclear power has proved controversial since the 1970s. Highly radioactive materials may overheat and escape from the reactor building. Nuclear waste (spent nuclear fuel) needs to be regularly removed from the reactors and disposed of safely for up to a million years, so that it does not pollute the environment. Recycling of nuclear waste has been discussed, but it creates plutonium which can be used in weapons, and in any case still leaves much unwanted waste to be stored and disposed of. Large, purpose-built facilities for long-term disposal of nuclear waste have been difficult to site, and have not yet reached fruition.

By the late 1970s, nuclear power suffered a remarkable international destabilization, as it was faced with economic difficulties and widespread public opposition, coming to a head with the Three Mile Island accident in 1979, and the Chernobyl disaster in 1986, both of which adversely affected the nuclear power industry for decades thereafter. A cover story in the February 11, 1985, issue of Forbes magazine commented on the overall management of the nuclear power program in the United States:

The failure of the U.S. nuclear power program ranks as the largest managerial disaster in business history, a disaster on a monumental scale ... only the blind, or the biased, can now think that the money has been well spent. It is a defeat for the U.S. consumer and for the competitiveness of U.S. industry, for the utilities that undertook the program and for the private enterprise system that made it possible.

So, in a period just over 30 years, the early dramatic rise of nuclear power went into equally meteoric reverse. With no other energy technology has there been a conjunction of such rapid and revolutionary international emergence, followed so quickly by equally transformative demise.

21st century

The 2011 Fukushima Daiichi nuclear disaster in Japan, the worst nuclear accident in 25 years, displaced 50,000 households after radiation leaked into the air, soil and sea.

In the 21st century, the label of the "Atomic Age" connotes either a sense of nostalgia or naïveté, and is considered by many to have ended with the fall of the Soviet Union in 1991, though the term continues to be used by many historians to describe the era following the conclusion of the Second World War. Atomic energy and weapons continue to have a strong effect on world politics in the 21st century. The term is used by some science fiction fans to describe not only the era following the conclusion of the Second World War but also contemporary history up to the present day.

The nuclear power industry has improved the safety and performance of reactors, and has proposed new safer (but generally untested) reactor designs but there is no guarantee that the reactors will be designed, built and operated correctly. Mistakes do occur and the designers of reactors at Fukushima in Japan did not anticipate that a tsunami generated by an earthquake would disable the backup systems that were supposed to stabilize the reactor after the earthquake. According to UBS AG, the Fukushima I nuclear accidents have cast doubt on whether even an advanced economy like Japan can master nuclear safety. Catastrophic scenarios involving terrorist attacks are also conceivable. An interdisciplinary team from MIT has estimated that if nuclear power use tripled from 2005 to 2055 (2%–7%), at least four serious nuclear accidents would be expected in that period.

In September 2012, in reaction to the Fukushima disaster, Japan announced that it would completely phase out nuclear power by 2030, although the likelihood of this goal became unlikely during the subsequent Abe administration. Germany plans to completely phase out nuclear energy by 2022.

Chronology

A large anti-nuclear demonstration was held on May 6, 1979, in Washington D.C., when 125,000 people including the Governor of California, attended a march and rally against nuclear power. In New York City on September 23, 1979, almost 200,000 people attended a protest against nuclear power. Anti-nuclear power protests preceded the shutdown of the Shoreham, Yankee Rowe, Millstone I, Rancho Seco, Maine Yankee, and about a dozen other nuclear power plants.

On June 12, 1982, one million people demonstrated in New York City's Central Park against nuclear weapons and for an end to the cold war arms race. It was the largest anti-nuclear protest and the largest political demonstration in American history. International Day of Nuclear Disarmament protests were held on June 20, 1983, at 50 sites across the United States. In 1986, hundreds of people walked from Los Angeles to Washington, D.C., in the Great Peace March for Global Nuclear Disarmament. There were many Nevada Desert Experience protests and peace camps at the Nevada Test Site during the 1980s and 1990s.

On May 1, 2005, forty thousand anti-nuclear/anti-war protesters marched past the United Nations in New York, 60 years after the atomic bombings of Hiroshima and Nagasaki. This was the largest anti-nuclear rally in the U.S. for several decades.

Nuclear arms reduction

  • 8 December 1987 – The Intermediate-Range Nuclear Forces Treaty is signed in Washington 1987. Ronald Reagan and Mikhail Gorbachev agreed after negotiations following the October 11–12, 1986 Reykjavík Summit to go farther than a nuclear freeze – they agreed to reduce nuclear arsenals. IRBMs and SRBMs were eliminated.
  • 1990–Present – Nuclear power is the primary source of electricity in France. Throughout the 1990s and 2000s (decade), France produces over three quarters of its power from nuclear sources (78.8%), the highest percentage in the world during these 2 decades.
  • 31 July 1991 – As the Cold War ends, the Start I treaty is signed by the United States and the Soviet Union, reducing the deployed nuclear warheads of each side to no more than 6,000 each.
  • 1993 – The Megatons to Megawatts Program is agreed upon by Russia and the United States and begins to be implemented in 1995. When it is completed in 2013, five hundred tonnes of uranium derived from 20,000 nuclear warheads from Russia will have been converted from weapons-grade to reactor-grade uranium and used in United States nuclear plants to generate electricity. This has provided 10% of the electrical power of the U.S. (50% of its nuclear power) during the 1995–2013 period.
  • 2006 – Patrick Moore, an early member of Greenpeace and environmentalists such as Stewart Brand suggest the deployment of more advanced nuclear power technology for electric power generation (such as pebble-bed reactors) to combat global warming.
  • 21 November 2006 – Implementation of the ITER fusion power reactor project near Cadarache, France is begun. Construction is to be completed in 2016 with the hope that the research conducted there will allow the introduction of practical commercial fusion power plants by 2050.
  • 2006–2009 – A number of nuclear engineers begin to suggest that, to combat global warming, it would be more efficient to build nuclear reactors that operate on the thorium cycle.
  • 8 April 2010 – The New START treaty is signed by the United States and Russia in Prague. It mandates the eventual reduction by both sides to no more than 1,550 deployed strategic nuclear weapons each.
