摘要:

From its beginnings in the 18th century the metric system has increased in recognition and has developed towards the SI units which are now in use throughout the world for scientific, technological, and increasingly for everyday use. MKS electrical units, devised at the beginning of this century to simplify electrical calculations, have also developed, and are now incorporated in the SI units. The advent of this simple and unified system of units has stimulated a revolution in the teaching of the theory of electricity and magnetism.

摘要:

The study of solids, at static pressures up to 500 kilobars, and transient pressures up to ∼ 5 × 106bars (1 bar = 0.99 atmospheres), has increased rapidly in the last ten years. Under pressure, all solids show a variety of atomic and electronic transformations into more condensed forms, eventually approaching a metallic state. As well as providing novel forms of matter to study, these experiments give data on the stability and cohesion in different types of crystal, the transition from the insulator to the metallic state, equations of state, melting phenomena and geophysical problems. In this review the experimental methods are briefly surveyed, and some of the more important results on typical ionic, covalent, metallic and molecular crystals are discussed.

摘要:

During the last decade an acceptable explanation of superconductivity at the atomic level has been developed. In this article the physical principles underlying the electron pair theory are described. Experimental verification of the theory and its application to real superconductors are examined.

摘要:

In this article the various pieces of apparatus at present available for use in schools or colleges that can be used to give useful experimental data are considered and comparisons made as regards cost, ease of use by students, and accuracy.

摘要:

The accurate measurement of the thermal conductivity of metals still poses considerable experimental difficulty. The reasons for this, and the main ways in which the problem has been approached, are summarized. A detailed examination of the development in technique and methods of measurement shows that while most of the steady-state methods introduced over 50 years ago are still being improved, the emphasis in the last few years has been on the development of methods which give more rapid results, particularly at high temperatures.
