This article traces the etymology of the term ‘revolution’ as it developed in Việt Nam between the second half of the nineteenth and the early twentieth centuries. It argues that the term was slow to catch on, and that activists who used it did so in often contradictory ways. The term's historical development complicated efforts to fix its meaning, and it was not until the later part of the 1920s that it came to be consolidated, in part through Hồ Chí Minh's publication of a short book entitledĐường Kách Mệnh(The road to revolution).

Great Complexity

As in every other branch of learning, the study of the early history of Christianity has undergone massive changes during the last century. This has been due not only to the vast accumulation of knowledge through new discoveries, but to new approaches to the subject, together with the rise of archaeology as a principal factor in providing fresh information. The study of the early Church has as a result moved steadily from dogma to history, from attempts to interpret divine revelation through the development of doctrinal orthodoxy down the ages, to research into the historical development of an earthly institution of great complexity and of great significance in the history of mankind over the past two thousand years.

The University

Alfred Wegener never set out to be a geologist. With an education in meteorology and astronomy, his career seemed clear when he was appointed Lecturer in those subjects at the University of Marburg, Germany. It wasn’t until 1912, when Wegener was 32, that he published a paper titled “Die Entstehung der Kontinente” (The origin of the continents) in a recently founded journal called Geologische Rundschau. This meteorologist had just fired the opening shot in a revolution that would change the way that geologists thought about the earth. In a series of publications and talks both before and after World War I, Wegener pressed the idea that continents moved around the earth independently of each other and that the present continents resulted from the splitting of a large landmass (we now call it a “supercontinent”) that previously contained all of the world’s continents. After splitting, they moved to their current positions, closing oceans in front of them and opening new oceans behind them. Wegener and his supporters referred to this process as “continental drift.” The proposal that continents moved around the earth led to a series of investigations and ideas that occupied much of the 20th century. They are now grouped as a set of concepts known as “plate tectonics.” We begin this chapter with an investigation of the history of this development, starting with ideas that preceded Wegener’s proposal. This is followed by a section that describes the reactions of different geologists to the idea of continental drift, including some comments that demonstrate the rancorous nature of the debate. The next section discusses developments between Wegener’s proposal and 1960, when Harry Hess suggested that the history of modern ocean basins is consistent with the concept of drifting continents. We finish the chapter with a brief description of seafloor spreading and leave a survey of plate tectonics to chapter 2. Although Wegener is credited with first proposing continental drift, some tenuous suggestions had already been made. We summarize some of this early history from LeGrand (1988).

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.
