The science and scientific legacy of Operation Chastise

Abstract

Operation Chastise, more often known as the 'Dambusters raids', was one of the most audacious aerial military operations of the Second World War, in that it made use of operationally untested technical innovations under extreme logistical constraints. Of particular interest is the scientific environment in which the mission was implemented. Here I review the principal scientific innovations that were necessary for the realisation of the mission. These went beyond the rotating depth charge itself. Simple but nevertheless ingenious methods for altitude and range finding were devised for low altitude flying, and the new system of two stage blue day–night flying was implemented for simulated night flying. Even drugs to combat airsickness during low altitude flight in turbulence were tested. The diverse technical expertise that was necessary for the original idea to be transformed into a logistical reality in less than three months provides a particularly lucid instance of effective scientific management in a framework of rapid technological change. I also describe an expedition inspired by these developments, which fifty years on used a dedicated low altitude night flying microlight aircraft (the Barnes Wallis Moth Machine) to catch insects over a rainforest canopy, illustrating the legacies that such missions can leave.     

Passing strange: the convergence of evolutionary science with scientific history

In the second half of the twentieth century, a surprising change in the notion of scientific truth gained ground when an evolutionary cosmology made the Newtonian world machine into no more than a passing phase of the cosmos, subject to exceptions in the neighborhood of black holes and other unusual objects. Physical and chemical laws ceased to be eternal and universal and became local and changeable, that is, fundamentally historical instead, and faced an uncertain, changeable future just as they had in the initial phases of the cosmos. The earth sciences along with biology had become historical in the nineteenth century; and the Big Bang cosmology in effect brought physics and chemistry into line, allowing venturesome intellects to concoct a new all‐embracing worldview that recognizes the catalytic role of the observer in defining what is observed, and how different levels of local complexity provoke new and surprising phenomena—including terrestrial life forms, and most notably for us, humanly‐constructed symbolic meanings—of which science is only oneexample. The article then argues that it is time for historians to take note of the imperial role thus thrust upon their discipline by making a sustained effort to enlarge their views and explore the career of humankind on earth as a whole, thus making human history an integral part of the emerging scientific and evolutionary worldview. Tentative suggestions of how this might be addressed, focusing on changes in patterns of communication that expanded the scale of human cooperation, and thus conduced to survival, follow. Dance, then speech, were early breakthroughs expanding the practicable size of wandering human bands; then caravans and shipping allowed civilizations to arise; writing expanded the scale of coordination; warfare and trade harshly imposed best practice across wide areas of Eurasia and Africa and kept the skills of that part of the world ahead of what the peoples of other continents and islands had at their command. Then with the crossing of the oceans after 1492 our One World began to emerge and swiftly assumed its contemporary shape with further improvements in the range and capacity of communication—for example, printing, mechanically‐powered transport, instantaneous data transmission—with consequences for human society and earth's ecosystem yet to be experienced. Much remains to be investigated and, in particular, interactions between the history of human symbolic meanings and the history of other equilibria—ecological, chemical, physical—within which we exist needs further study. But with suitable effort, history can perhaps become scientific and the emerging scientific evolutionary worldview begin to achieve logical completeness by bringing humankind within its scope.     

Between science and religion: The reaction to scientific naturalism in late Victorian England

From its ornamental and often bookish exterior to its use as an exegetical tool for understanding the Book of Nature, the 18th-century microscope was socialized as an instrument of letters as well as of science. This essay proposes a reading of the microscope as a literary artifact by examining its bindings, its texts and its illustrations. While the instrument promised to extend human sense perception and to give its user access to invisible worlds, it simultaneously threatened to alter received views concerning both aesthetics and social hierarchy. Nevertheless, the destabilizing effects of the microscopic message entered polite society cloaked in a veil of familiarity in the binding of a good book. The nostalgia-encrusted instrument absorbed the shock of the new.     

L.A. Orbeli - outstanding physiologist and science leader of the twentieth century

L.A. Orbeli and his school developed new directions in physiology: evolutionary physiology, the theory of adaptational-trophic functions of the sympathetic nervous system, the theory of coordination of functions, and neuroendocrine regulations in the body. Orbeli enriched the study of the physiology of the cerebellum, the sensory organs, the kidneys, and the study of pain. His name is associated with the development of the foundation of physiology of extreme states (the physiology of deep-sea exploration, high altitude, and high velocity flight).     

'Liberty and truth' or 'the sovereignty of reason': Carlo Cattaneo and the place of politics in the modern world

My purpose here is to place the thought of Carlo Cattaneo in relation to French Restoration liberalism, and I therefore consider the doctrinaire school (among others, Guizot and Cousin) and the Coppet Circle (notably, Constant, StaËl and Sismondi). A concern to render reason sovereign was perhaps shared by all in post-revolutionary Europe who were cultivating human or social science, yet there was in Guizot's concept of 'the sovereignty of reason' a spiritualist, authoritarian and anti-individualist implication. By contrast, Cattaneo wished to honour 'the truth of local facts', that is the specific attributes of all the parts of which a state consisted, and in this regard his thought is descended not from the doctrinaires but from the individualist liberalism of Constant. I also remark upon Cattaneo's debt, openly declared, to the earlier historical writings of Thierry,and therefore to the political precepts of the late id é ologue tradition. Il mio scopo è quello di porre il pensiero di Carlo Cattaneo in relazione al liberalismo francese durante il periodo della Restaurazione, e confrontarlo in particolare con l'Ecole Doctrinaire (tra gli altri, Guizot e Cousin) ed il Circolo Coppet (principalmente, Constant, StaËl e Sismondi). L'idea di rendere la ragione sovrana era forse un sentimento condiviso da molti intellettuali nell'Europa post-rivoluzionaria, specialmente in coloro che dedicavano attenzione ed interesse alle scienze umane e sociali; tuttavia, nel concetto di Guizot sulla 'sovranitÀ della ragione' era insita una componente spiritualista, autoritaria ed antindividualista. Cattaneo, diversamente, tendeva ad onorare 'la veritÀ delle realtÀ locali', ossia di tutte le caratteristiche insite negli innumerevoli elementi di cui lo stato è composto; ed in questo aspetto, il suo pensiero traeva ispirazione dal liberalismo individualista di Constant piuttosto che dai doctrinaires. Credo anche che il liberalismo di Cattaneo sia dichiaratamente debitore verso gli scritti di Thierry ed inoltre nei confronti della filosofia politica appartenente alla tradizione degli idéologues.

Veterinary immunology as colonial science: method and quantification in the investigation of horsesickness in South Africa, C. 1905-1945

This article examines the practice of veterinary immunology in South Africa during the first half of the twentieth century through an analysis of research into a horsesickness vaccine at the Onderstepoort Veterinary Institute. From the early 1900s, Arnold Theiler prioritized research into horsesickness, by then defined as an insect-borne disease caused by an ultravisible virus. He succeeded in devising a means of prophylaxis using a simultaneous injection of infective blood and immune serum, but he discovered antigenically different strains of the virus, which could overcome the immunity produced by his treatment. The practical value of Theiler's methods was further limited by difficulties in standardizing the biological material used in immunization, the results of which remained too erratic for application on a large scale. No further advances were made until the 1930s, by which time Onderstepoort had been drawn more closely into international scientific networks. Using techniques derived from research into yellow fever in America and canine distemper in Britain, the Onderstepoort scientist Raymond Alexander invented a method of immunization that utilized the propagation of the horsesickness virus in the brains of mice. Alexander's methods, which were characterized by successful technical adaptation and innovation, depended upon methods of quantification first developed by Paul Ehrlich to standardize diphtheria antitoxin during the 1890s. During the 1940s, vaccination expanded rapidly in South Africa, and Onderstepoort later exported the vaccine and associated technology to other countries affected by horsesickness.
