摘要:

A simple physical explanation is given for the formation of Cooper pairs in a superconducting metal, for the origin of the attractive force causing the binding of the pairs, for the forming of a degenerate Bow gas by the Cooper pairs, for the finite energy gap that prevents the ensemble of electrons from changing its quantum state at low temperatures, and for the existence of permanent currents in a superconducting wire.

摘要:

Data from space missions of various kinds coupled with those from Earth-based observatories have allowed us to pass beyond the separate study of individual planets to the study of the Solar System as a composite physical system. We can identify those physical principles which are characteristic of planetary bodies over the full range of possible sizes. This article offers a broad general survey of the physics of planetary interiors in these terms, without concentrating in detail on any particular planetary body. The aim is to highlight significant areas which could repay future study, as well as to explain what is already understood. Magnetism will not be included nor will matters involving possible origins of the Solar System.

摘要:

There falls on the Earth's atmosphere a rain of particles and photons the high energy part of which is termed the Cosmic Radiation. This article is concerned specifically with primary particles of the highest known energies, i.e. 1017-1020eV and deals with the evidence for their existence, their nature and their origin.

摘要:

The neutron spin-echo (NSE) spectrometar provides the highest energy resolution available in neutron scattering experiments. The article describes the principles behind the first NSE spectrometer (at the Institute Laue-Langevin, Grenoble, France) and, as an example of one of its applications, some recent results on polymer chain dynamics are presented.
