Computers and Liquid State Statistical Mechanics

The advent of electronic computers has revolutionised the application of statistical mechanics to the liquid state. Computers have permitted, for example, the calculation of the phase diagram of water and ice and the folding of proteins. The behaviour of alkanes adsorbed in zeolites, the formation of liquid crystal phases and the process of nucleation. Computer simulations provide, on one hand, new insights into the physical processes in action, and on the other, quantitative results of greater and greater precision. Insights into physical processes facilitate the reductionist agenda of physics, whilst large scale simulations bring out emergent features that are inherent (although far from obvious) in complex systems consisting of many bodies. It is safe to say that computer simulations are now an indispensable tool for both the theorist and the experimentalist, and in the future their usefulness will only increase. This chapter presents a selective review of some of the incredible advances in condensed matter physics that could only have been achieved with the use of computers.Comment: 22 pages, 2 figures.

American Medical and Intellectual Reaction to African Health Issues, 1850-1960: From Racialism to Cross-Cultural Medicine

During recent decades, social scientists, particularly anthropologists, sociologists and medical historians, have looked increasingly at how social and cultural factors inform a society\u27s medical community and vice-versa. As Roger Cooter recently stated, ... medicine is a social phenomenon capable of being properly studied only when treated as a part of its social, political, economic and cultural totality. [1] In America, a steady flow of medical sociologists -- most notably Henry E. Sigerist in the 1940s, Talcott Parsons in the 1950s, David Mechanic in the 1960s and 1970s, and Vern and Bonnie Bullough in the 1980s -- contributed numerous empirical studies that revealed that the development of American medicine was shaped moreso by its social and cultural context than clinical discoveries.[2] These studies have demonstrated conclusively that the American health profession\u27s approaches to disease (etiology and therapy), the institutional structure of medical research and care, and public health care policy all have been deeply influenced by socioeconomic and cultural factors specific to historical epochs of evolving American society

Relation of Magnetic and Gravity Field Data to Selected Structural Elements of the Central Portion of the Arkoma Basin

In order to acquire a greater understanding of some of the major basement structural features characteristic of the Arkoma basin, magnetic and gravity data have been collected and analyzed for a selected area. Several anomalies exist and are found to be associated with faulting or major fracturing in the Precambrian basement. Modelling of source bodies based on magnetic and gravity values provides quantitative estimates of the depth as well as the geometry of basement structural geology
