摘要:
The interactions of π mesons with nuclei are reviewed and interpreted in terms of the Serber model of nuclear reactions at high energies. This involves introducing the concept of a mean free path for both meson scattering and absorption in nuclear matter. These quantities are discussed in relation to the relevant experimental data. A discussion of the “optical model” of nuclear scattering is also included.

摘要:
The first application of the method of constructing the image of a point object by means of an unrefracted central ray and a ray which is parallel to the axis and is refracted through the focus was made by Robert Smith. A section of hisA Compleat System of Opticksis here reproduced.

摘要:
The units of susceptibility and magnetization can be chosen so that they are identical in the (unrationalized) 3- and 4-dimensional cgs systems. These units and the defining equations are given, and inconsistencies in the literature are pointed out. Adoption of the present definitions would eliminate much existing confusion and satisfy the various schools of thought.

摘要:
The concept of radiation pressure exerted against a reflecting surface by electromagnetic waves and by sound waves in gases is a familiar one. The absence of radiation pressure for sound waves in a “linear medium” is becoming well known. The equations are somewhat different for the radiation pressure for these two cases where the radiation pressure is not zero. The mechanisms usually called on to explain them (nonlinearity of the equation of state of the gas, acceleration of charges in the reflector by the electromagnetic waves) are widely removed from each other. Consequently, it is not evident on the surface whether radiation pressure is a general property of waves or the capricious result of isolated physical phenomena associated with some waves.A generalized concept of radiation pressure is here developed and then applied to several kinds of waves: sound waves in various media, waves on strings and springs, electromagnetic waves. Also, a simple demonstration of radiation pressure (for waves in a ripple tray) is described.
