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...

Drafting with Sequences

The numbers on the inner circle are those that exist in the modular arithmetic. If we continue beyond 7, as shown in the outer ring, the numbers wrap around the wheel. Numbers on the same spoke are equivalent. For example, 0 and 8 are equivalent, 1 and 9 are equivalent, 2 and 10 are equivalent, and so on. Another way to look at it is that when 9 is introduced into modular arithmetic with 8 shaf...

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...

Drafting Indemnification Clauses

A typical indemnification clause requires the indemnitor to “indemnify and hold the indemnitee harmless.” It might also require the indemnitor to “defend” the indemnitee. While most legal authorities agree that the obligation to defend is different from the obligations to indemnify and hold harmless, many regard the promises to indemnify and hold harmless as synonymous, suggesting that either b...
