Civil engineering and social change: The early history of the ParisEcole des ponts et chaussées

Recent monographs on Russian social development have raised a number of hypotheses regarding our general understanding of processes of political and social change. In his volume on the early history of Russian workers Reginald Zelnik, for instance, proposes that moderate labor unrest reinforced traditional repressive patterns, while extreme conflicts motivated innovative reform. In the work of Robert E. Johnson and of Victoria Bonnell we find the suggestion that workers in small-scale enterprises and artisan shops were often more radical and organized than those in larger industrial enterprises. The fragmented and antagonistic nature of Russian society, with multiple splits of both an intergroup and intragroup nature, has been noted in the work of both Roberta Manning and Allan Wildman. Diane Koenker, focusing her research on the period of the 1917 revolutions, has brought out the moderating and integrating effect of the urban setting on Russian workers. These are only a few of the many thought-provoking hypotheses that have been raised.

The Way

No appreciation for the early history of the Turkish Republic can begin without a proper understanding of the origins, desires, and tribulations of the Young Turks. Their era by no means constituted a mere placeholder or prologue to the dramatic events that occurred thereafter. Turkey, as it came to be defined philosophically, was the unintended offspring of this movement. The most profound attributes of Atatürk’s state, its thirst for radical social change, its predilection for chauvinistic nationalism, and its oligarchic structure, descended directly from the Committee of Union and Progress’ approach towards politics. Ultimately, their displacement from the imperial stage allowed for Mustafa Kemal to rise to prominence and paved the way for an altogether new regime.

Twin Crisis

The formative period of Imami Shiʿism from the mid-8th century to the mid-10th century remains obscure in many respects. This study is an attempt to organize the historical information about the period around a central problematic: the twin crisis of the nature of the Imamate and the succession to this office. The crisis of the Imamate and the efforts to resolve it serve as a focal point for constructing a conceptually coherent overview of these two formative centuries from a sociohistorical perspective. This perspective requires that the endeavors to create a stable system of authority in Imami Shiʿism be considered in the context of the social change and politics of the early ʿAbbasid era: ʿAlid–ʿAbbasid relations, massive conversion of the population of Iran to Islam, and the dialogue and competition between Shiʿism and other contemporary religious and intellectual trends and movements. Our approach suggests a new periodization of the early history of Imami Shiʿism.

Electron Microscopes

By 1940, a half dozen or so commercial or home-built transmission electron microscopes were in use for studies of the ultrastructure of matter. These operated at 30-60 kV and most pioneering microscopists were preoccupied with their search for electron transparent substrates to support dispersions of particulates or bacteria for TEM examination and did not contemplate studies of bulk materials. Metallurgist H. Mahl and other physical scientists, accustomed to examining etched, deformed or machined specimens by reflected light in the optical microscope, were also highly motivated to capitalize on the superior resolution of the electron microscope. Mahl originated several methods of preparing thin oxide or lacquer impressions of surfaces that were transparent in his 50 kV TEM. The utility of replication was recognized immediately and many variations on the theme, including two-step negative-positive replicas, soon appeared. Intense development of replica techniques slowed after 1955 but important advances still occur. The availability of 100 kV instruments, advent of thin film methods for metals and ceramics and microtoming of thin sections for biological specimens largely eliminated any need to resort to replicas.
