After Russia invaded Ukraine in February 2022, the Worldwide Union of Pure and Utilized Physics (IUPAP), then celebrating its one centesimal anniversary, issued an announcement condemning the conflict. It famous its dedication to “embrace and promote scientific collaboration the world over as a driver for peace”.
This rhetorical relationship between science and peace just isn’t new. All through historical past, many individuals have stated that science is intrinsically common, and that its supposed impartial language and strategies present widespread floor for transnational communication. This universalism, so the argument goes, can in flip favour peaceable relations amongst peoples and nations. However none of it is a given1. A guide we edited, Globalizing Physics, revealed earlier this 12 months, explores the various ways in which physicists, each individually and collectively, navigated the rocks and whirlpools of geopolitical tensions all through the 20th century — typically efficiently, typically much less so.
Idealism and realism
The story of how, from a shaky starting, IUPAP turned an agent of worldwide diplomacy, reveals how internationalism and universalism should be nurtured by scientists within the altering cultural, financial and political conditions into which they’re inserted. It has classes nicely past the boundaries of physics within the tense geopolitics of at this time.
IUPAP arose within the ashes of conflict. Quickly after the top of the First World Warfare, a motion sprung as much as create worldwide scientific unions underneath the umbrella of the Worldwide Analysis Council (IRC), with the thought of forging collaboration between nations and, not directly, securing lasting peace. IUPAP was a part of that motion. It was formally established in 1922 as an affiliation of nationwide physics committees. It held its first normal meeting in 1923 with 16 members — 12 from Europe, plus Canada, Japan, South Africa and the USA.

Issues didn’t begin nicely. For all of the effective internationalist sentiment, the IRC’s statutes had been formed by punitive attitudes from France and Belgium towards Germany, and had been express about excluding the conflict’s defeated events2. This exclusionary coverage was significantly irritating for IUPAP, given the central function of the German-speaking physics neighborhood within the disruptive advances in quantum physics and elsewhere of the Twenties. It resulted in IUPAP being, by the Nineteen Thirties, virtually completely defunct.
In 1931, the IRC turned the Worldwide Council of Scientific Unions (ICSU), dropping its coverage and giving extra freedom to the person scientific unions3. What might have been a possibility to revive IUPAP was scuppered, this time by Germany. German-speaking physicists had been organized into a number of scientific our bodies, and the 2 most influential, the German Bodily Society and the German Society for Technical Physics, couldn’t resolve who ought to characterize them. This downside compounded with the consolidation of the Nazis in energy and the emergence of the nationalistic scientific motion referred to as Deutsche Physik (German Physics)4 within the mid-Nineteen Thirties.
Transatlantic shift
In 1931, the US physicist Robert Millikan assumed the IUPAP presidency. He had grand plans to offer the union a function by means of the group of conferences, significantly a big one to be held in Chicago, Illinois, in 1933. His concept was not solely to advertise internationalism, but in addition to shift the union’s focus from Europe to the USA. The tough financial circumstances of the Nice Despair meant that his plans didn’t come to fruition. Along with the tensions surrounding Germany, this resulted in a widespread pessimism about the way forward for IUPAP.

This wasn’t as a result of there was no worldwide collaboration in physics. Atomic and nuclear physics had been booming as quantum concept and the speculation of relativity had been being consolidated and applied sciences akin to radio broadcasting emerged. Niels Bohr, a pioneer of quantum concept whose institute in Copenhagen had been a hub of impartial internationalism throughout the Twenties and early Nineteen Thirties, was nominated as president of IUPAP in 1934. However he turned the place down, fearing the lack of his impartial popularity had been he to be related to it.
As a tragic image of IUPAP’s failure to bolster worldwide cooperation in its early years, the union’s secretary-general and doubtless its most lively member from its inception, the French physicist Henri Abraham, was murdered within the Auschwitz focus camp, Poland, in 1943.
Chilly conflict diplomacy
Within the aftermath of the Second World Warfare, physicists discovered themselves in a reworked public and political panorama. The event and deployment of nuclear weapons had considerably altered their public picture, and so they had been now thought to be integral to state energy and safety. This shift occurred in a world marked by ideological, political, financial and army competitors between East and West, in addition to by the onset of decolonization. Consequently, the function and function of IUPAP needed to be reconfigured.
Studying from previous errors, the IUPAP secretary-general in 1946–47, Paul Ewald — a German-born crystallographer who had emigrated to the UK in 1937 to flee the Nazi regime — proposed the inclusion of physicists from defeated nations as quickly as potential. This led to the speedy entrance of Italy and, quickly after, West Germany and Japan — West Germany even earlier than it turned a sovereign state — within the union.

Regardless of these efforts, IUPAP nationwide members initially belonged to the Euro–Atlantic political alliance, alongside a number of non-aligned nations. This was principally owing to the isolationist insurance policies of the Soviet Union, which started to shift solely after the demise of its chief Joseph Stalin and the top of the Korean Warfare in 1953. IUPAP officers actively labored to alter the scenario by forging contacts with physicists from the Jap Bloc. Nevill Mott, the UK physicist who was IUPAP’s president from 1951 to 1957, declared that involving Soviet physicists was a significant objective of his presidency, and the Italian physicist Edoardo Amaldi was elected president in 1957 as a result of it was thought that he might create beneficial situations for a Soviet nationwide committee to affix.
That did finally occur in 1957, adopted by the participation of different nations within the Soviet sphere of affect. This eastwards enlargement rewrote IUPAP’s worldwide function. Physicists started to view its conferences and commissions as helpful venues for East–West encounters throughout a interval of tense worldwide relations, successfully participating in what’s now termed science diplomacy5. All through the Chilly Warfare, IUPAP officers couldn’t, and didn’t, ignore the diplomatic implications of their actions. In 1969, affiliate secretary-general Larkin Kerwin even introduced that IUPAP’s unofficial objective was to contribute to “normal worldwide understanding”6.
Disputed delegations
Political authorities in territories whose independence was contested throughout the chilly conflict had been taken with becoming a member of worldwide scientific establishments as a solution to acquire recognition. This situation emerged quickly after the doorway of the Soviet Union. IUPAP officers needed to tackle the ‘two-China’ downside, with parallel membership requests, first from the Chinese language Bodily Society in Beijing within the Individuals’s Republic of China (PRC) and the second being a US-backed request from the Chinese language Bodily Society in Taipei, Taiwan (the Republic of China, or ROC).
The same situation arose with the Bodily Society of the German Democratic Republic — East Germany — which utilized for illustration individually from West Germany. These requests had probably disruptive political implications, relying on how the time period ‘nationwide committee’ was to be interpreted.

Though governments had no official voice in IUPAP administration, the problems at stake right here had been vital for a lot of nationwide authorities. Many physicists sided with their governments’ agendas, however others didn’t. Amaldi and different IUPAP officers acted independently, advocating the speedy acceptance of all three requests by 1960. This method aimed to indicate that IUPAP might overcome chilly conflict imperatives, behaving in a balanced manner. Many years later, the admission of East Germany’s bodily society was acknowledged by IUPAP officers in letters and public statements as a pivotal second in establishing the union’s independence from governmental affect and defining its diplomatic function. IUPAP was among the many first worldwide organizations to formally acknowledge the German Democratic Republic as a separate entity.
Nevertheless, IUPAP’s assertion that admitting the East German and Taiwanese societies was politically equal revealed a restricted understanding of the distinct contexts of the German and Chinese language conditions. Not like the Germanies, each the PRC and the ROC claimed to characterize all of China, complicating their simultaneous membership in IUPAP. When IUPAP officers determined to simply accept each of those societies, the PRC’s bodily society withdrew its request. Physicists from the PRC remained excluded from the union for nearly 25 years.

Solely in 1984 did the PRC’s bodily society be a part of IUPAP, following improved relations between the PRC and the USA, but in addition plenty of work on IUPAP’s aspect over the 20 years, altering statutes and formally redefining membership, with ‘nationwide committees’ being renamed ‘liaison committees’. The ultimate inclusion of each societies turned a testomony to the physicists’ capacity to attain diplomatic outcomes parallel to, and independently of, intergovernmental diplomacy.
The popularity within the late Nineteen Fifties that IUPAP additionally had a diplomatic perform led to calls for that every one IUPAP-sponsored conferences be open to all physicists worldwide, no matter their nation of origin. This concerned the difficult job of securing visas for scientists to journey throughout the Iron Curtain. Starting with a vocal protest by IUPAP officers towards a NATO-imposed ban on East German scientists, these efforts developed right into a normal precept often known as the Free Circulation of Scientists, which was adopted by the ICSU and all its unions. Fostering this precept turned a defining job of IUPAP till the top of the chilly conflict, and was included as one of many group’s primary goals in its Nineteen Eighties statutes.
Going world
As decolonization progressed and the chilly conflict got here to an finish, IUPAP sought to characterize physicists worldwide by enlarging its membership past the chilly conflict blocs. This renewed challenges concerning IUPAP’s identification and the connection between physics and politics.
From its inception, IUPAP was conceived of as a union about each pure and utilized physics, however the meanings and the representations of each phrases modified all through the 20th century. Throughout the chilly conflict, ‘pure’ was typically used as a label to rhetorically exonerate physics from its pivotal function within the arms race, suggesting that physicists might discover a widespread floor to transcend political tensions. Concurrently, the East–West competitors for scientific supremacy disregarded the growing reliance of physicists on extra complicated and costly experimental gear that necessitated collaboration throughout borders.
Moreover, the picture of physics because the ‘king of the sciences’ was quickly fading away throughout this era7, and the importance of the self-discipline within the broader community of science and expertise in creating nations couldn’t be taken as a right. Two IUPAP commissions had been created to handle these considerations: the Fee on Physics Training in 1960, and the Fee on Physics for Growth in 1981. Each nonetheless exist.

Initially, this was marked by patronizing attitudes from many physicists in higher-income nations, who assumed that lower-income nations couldn’t afford, and had been usually not taken with, pure science, with their wants being extra aligned with sensible, industrial and technological developments.
The primary two Worldwide Conferences on Physics Training co-organized by IUPAP, held in 1960 in Paris and in 1963 in Rio de Janeiro, Brazil, highlighted this disconnect, revealing the necessity to not simply enhance physics schooling, but in addition broaden the career past a pure science practised in specialised college departments. It took a number of a long time for more-complex views to emerge concerning the connection between physics schooling and developmental points. Ultimately, IUPAP physicists reconfigured the group’s priorities, inserting better emphasis on industrial issues, inclusivity and aligning with the sustainability agendas promoted by the United Nations within the 2000s8.
Worldwide scientific organizations akin to IUPAP have functioned successfully as devices of science diplomacy solely when their scientists have express consciousness of their diplomatic roles. That carries classes into the current day. One guideline that has formed IUPAP’s actions for the reason that Second World Warfare is to cease physicists being seen merely “cog[s] within the army machine”, Ewald stated. One other, rising from its disastrous expertise within the years between the primary and second world wars, is the dedication to keep away from any type of boycott, with the objective of fostering worldwide collaboration and, informally, being a diplomatic channel when others are blocked.
The current response of IUPAP to Russia’s invasion of Ukraine demonstrates these rules. Though IUPAP condemned the conflict, it additionally issued an announcement emphasizing the significance of preserving channels of scientific cooperation open throughout all political and ideological divides, and reiterating that barring scientists from scientific exercise on the idea of their location is inappropriate.
There’s an innate pressure in these positions. Upholding them is probably possible solely as a result of IUPAP doesn’t have interaction in particular analysis tasks, particularly these with dual-use functions which can be probably each peaceful and non-peaceable. Classes from IUPAP’s historical past may not be universally relevant, being reasonably particular to sure contexts of scientific cooperation and dialogue. However they do serve for instance an central precept: that scientific internationalism just isn’t a given, however is the result of efforts from scientists each individually and collectively.
