The aims of the association are to promote cooperation amongst European research organisations and their scientific communities in furthering research involving computationally intensive methods. It began as a laboratory in Orsay, a campus of the University of Paris, and moved to Lyon in the early 1990s. Since the beginning of 2008, CECAM is hosted by the Swiss Institute of Technology Lausanne, Switzerland. Its director is Dominic Tildesley. ==Early years of CECAM in Orsay== The laboratory was initiated in 1968 by Carl Moser, an American scientist naturalized in France. Moser was an associate of the well known French theoretical chemist Raymond Daudel,〔R. Daudel, R. Lefebvre and C. Moser, Quantum Chemistry〕 who was the Director of ''Centre Mechanique Ondulatoire'' in Rue de Maroc. Moser moved from Rue de Maroc to the Orsay campus, Université de Paris XI, and established a laboratory which served to connect the rather isolated community of French computational physicists, chemists and biologists with their homologues in the rest of Europe, the UK, and the USA. At the time the laboratory was set up, large-scale computational facilities were not readily available in most of Europe. Furthermore, the concept of basic simulations was not highly acclaimed as there were many physicists who believed that pencil, paper, and brain-power were all that was needed for scientific creativity. However, Moser's background in quantum chemistry, his familiarity with the work of S. F. Boys, and his stint in crystallography at the Institut Pasteur made him acutely aware of the need for computational approaches. Moser's concept of the laboratory was unique, in that it had basically very few or no permanent members. Instead it ran a series of "workshops", directed by one or two invited scientists who remained at CECAM during the period of the workshop. These workshops could run from three months to a few weks or even a week, with twenty or more participants. This enabled CECAM to cover a kaleidoscope of subjects, at a time when the approach of workshops was not well known. Many distinguished scientists, including Walter Kohn, Lars Hedin, Martin Karplus, R. K. Nesbet, Michael Klein, Art Williams, Anees Rahman, Mark Rasolt, Gabor Somorjai and plasma physicists including Hans Griem, Don DuBois, Balaz Rosznyai, James Dufty, were among the visitors to CECAM. A number of Russian scientists, including Ginzburg, also visited the laboratory. Many French scientists like Madam Marguerite Cornille, Michele Gupta, Francois Grimaldi, Francois Perrot, Madam Lebfevre and other friends of Moser were often seen at the laboratory. A few scientists like Chandre Dharma-wardana (NRCC), Gianni Jacucci and Girolamo Ramuni (CNAM), and Charles Sommers were longer-term members at various times in the mid-1970s. Wanda Andreoni was a post-doctoral fellow at the time, directed by Walter Kohn. But almost any one who was important in simulation physics in the USA or UK and Europe had visited the laboratory at some time or other. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Centre européen de calcul atomique et moléculaire」の詳細全文を読む スポンサード リンク
