“…These attributes have led many countries to pursue research on laser isotope separation. See Boureston and Ferguson (2005). Evidence of the optimism surrounding laser processes is that, at the time Urenco was developing their latest centrifuge technology, the US DOE instead concentrated its resources on developing the atomic vapor laser isotope separation (AVLIS) technique.…”

“…The lower energy and space requirements of a laser enrichment facility would theoretically make it more difficult to detect with conventional means than a centrifuge enrichment plant or a gaseous diffusion facility. [2,3] In addition, LIS processes involve airtight vessels filled with gasses that will not remain gaseous at room temperature. [4] This suggests that an LIS device is unlikely to leak anything into the surrounding environment that might be detectable from a distance.…”

“…France is competing with its ongoing Mégajoule project, with 240 lasers; other projects are under development in several other countries. The negative aspect is that progress in using such laser techniques for isotope separation seems to promise a method of uranium enrichment 62 that may be cheaper and more difficult to detect by means of inspections (Boureston and Ferguson 2005).…”

The Evolution of Knowledge

View full text Add to dashboard Cite

This volume presents results of an interdisciplinary research project on the globalization of knowledge. The project is centered at the Max Planck Institute for the History of Science. It was launched in 2007 at the 97 th Dahlem Workshop on Globalization of Knowledge and its Consequences, a Dahlem Conference hosted by the Free University Berlin and supported by the Deutsche Forschungsgemeinschaft (DFG). The Dahlem Conferences, with their unique mode of scholarly interaction, have played a key role in fostering an interdisciplinary cooperation that covers a vast array of disciplines, cultures and historical periods. I am grateful to Katharina Ochse, as well as to my colleagues from the Advisory Board of the Dahlem Conferences, for initiating us into the procedures of this workshop model. The numerous documents, papers, commentaries, reviews and discussion statements that have been produced in the process have all turned out to be essential in producing this volume.The project is part of the research program of a historical epistemology whose aim is to contribute also to the reflexivity of present science and its institutions. It pursues a comparative history of knowledge in which present processes of globalization are conceived as the outcome of historical developments and their interactions. The four research foci of the project have been chosen such that theoretical claims can be validated with reference to outstanding historical phases in which knowledge production, transmission and transformation were critical for advancing processes of intercultural exchange. The theoretical framework developed in the course of the project comprises a core set of concepts which should be extended and revised in the course of further research.The scholarly network, established in 2007, has since been significantly expanded. The participating scholars have collaborated in a variety of meetings and exchanges dedicated to the production of this working group volume. In addition to the papers originally submitted at the Dahlem Conference, a number of invited contributions have been integrated. All contributions have been peer-reviewed and also partly revised by members of an internal board, which met on several occasions to discuss the overall results of the cooperation and their presentation in the introductory survey chapters to each of the four parts of this volume. The internal board comprised
