Physicists with Philips

Technical Data from Philips

Radiological physicists

JUAN A. DEL REGATO, Radiologicalphysicists, New York, American Institute ofPhysics for the American Association of Physicists in Medicine, 1985, 4to, pp. v, 188, illus., $25.00. Radiology provided perhaps the main route by which physicists entered medicine in the period leading up the Second World War. Among other things, they were needed to develop and service X-ray and radium equipment; to de...

Physicists Thriving with Paperless Publishing Heath

The Stanford Linear Accelerator Center (SLAC) and Deutsches Elektro-nen Synchrotron (DESY) libraries have been comprehensively cataloguing the High Energy Particle Physics (HEP) literature online since 1974. The core database, SPIRES-HEP, now indexes over 400,000 research articles, with almost 50% linked to fulltext electronic versions (this site now has over 15 000 hits per day). This database...

Bayesians, Frequentists, and Physicists

PHYSTAT2003 brought statisticians together with particle physicists, astrophysicists, and cosmologists. This paper, which is taken from the text of the keynote address, concerns the uneasy relationship between Bayesian and frequentist statistics, with particular attention to the “neutrino problem”: how to set confidence limits for a parameter known to be non-negative. Model selection, an object...

Immunology for physicists

The immune system is a complex system of cells and molecules that can provide us with a basic defense against pathogenic organisms. Like the nervous system, the immune system performs pattern recognition tasks, learns, and retains a memory of the antigens that it has fought. The immune system contains more than 107 different clones of cells that communicate via cell-cell contact and the secreti...
