Abstract
PROF. P. W. BRIDGMAN, to whom the Nobel Prize for Physics for 1946 has been awarded, is celebrated for his comprehensive researches into the properties of matter at very high pressures, which began in 1906 and have continued with unabated vigour to the present day. By the ingenious applications of prin ciples in themselves simple and by the informed utilization of new steels, he extended the range of pressures at which systematic measurements could be made from 3,000 atmospheres, the limit reached by Amagat, to 12,000 atmospheres. Up to this pressure he measured, for example, compressibilities, vis cosities, electrical conductivities, thermal E.M.F. S and transition points of a large number of elements and compounds, with results of the highest interest. This work, which necessarily involved the working out of new methods of measuring pressure, is described in his book The Physics of High Pressure, which appeared in 1931 and has become the classic of the subject.
