摘要:

For the first time the vibrational population lifetime of simple normal modes of polyatomic molecules in liquids has been directly measured, according to the experimenters, Alfred Laubereau, Dietrich von der Linde and Wolfgang Kaiser (Munich Technical University). Earlier the vibrational dephasing lifetime in both liquids and solids had been measured by the Munich group, who studied polyatomic molecules in liquids and lattice vibrations in diamond, and by Robert Alfano and Stanley Shapiro (General Telephone and Electronics), who measured lattice vibration lifetimes in calcite and molecular vibrational lifetimes in liquid nitrogen. Some observers believe that the technique opens a new field for the study of molecular relaxations in liquids and optical phonon relaxations in solids.

摘要:

The electron–positron storage ring, SPEAR, is now running at SLAC as scheduled, and performance attained so far meets all expectations. Now SLAC, in collaboration with the Lawrence Berkeley Laboratory (LBL), is looking ahead to a still more powerful colliding‐beam device called “PEP”, a device that would involve collisions between protons, electrons and positrons.

摘要:

Although “everyone” has heard of IUPAP, many of us are unaware of what it is (a membership organization? an organization of other organizations?), what it does, and how it is financed (does the money come out of our American Physical Society or Optical Society dues? out of our taxes?).

摘要:

Conceived in 1965, born in 1968, and by now a healthy, growing four‐year‐old, the European Physical Society is an excellent example of successful cooperation among physicists of different countries. This article is the story of how this new society came into being. It takes us across the continent, north and south, east and west; it introduces us to the many individuals who had a part in the evolution of EPS, and it demonstrates how cultural and political differences can be submerged when the goal is worthwhile.

摘要:

Physicists in the US, and other scientifically advanced countries, can make a significant contribution to the growth of less developed countries throughout the world. Yet, probably only a few members of the physics community know that we are now living in the Second United Nations Development Decade, designed to aid in the evolution of the less developed countries. Because of the crucial role that science and technology must play in this development, a World Plan of Action for the Application of Science and Technology has been established, and is now being studied by the various bodies of the UN with the aim of eventual adoption by the General Assembly (see box for details of plan). Obviously, if this plan encounters indifference from the scientific community, it is likely to fail even if the governments of the more developed countries formally agree to participate in the plan. The lack of adequately trained manpower and a scientific isolation from the rest of the world are the two main problems facing these less developed countries. Therefore, in this article, I will propose some programs with which we physicists in the more advanced countries can mitigate these problems and thus contribute to the scientific emergence of the developing countries. I do this, however, with the full realization that the main task of science development must be carried out by indigenous personnel and manpower and that outside assistance must be primarily catalytic in nature. The purpose of international assistance is to make itself superfluous in the shortest possible time, and thus scientific help must aim at the vigorous development of local scientific infrastructures that can be self‐sufficient and productive in the not too distant future.
