摘要:

Michael Faraday, the experimentalist, is a well-known and beloved figure in the history of science; Michael Faraday, the theorist, is almost a stranger. The purpose of this paper is to describe Faraday's theoretical ideas on the structure of matter and to illustrate his use of these ideas as guides in his researches on electrolysis, static induction and ordinary electrical conduction.

摘要:

Radar Astronomy is a new and growing branch of Astronomy. Although it seems that radio echo studies must be confined to the solar system, they can play an important part in developing our understanding of the Sun and the planets. At the present time these objects are barely detectable by radar techniques and much of the work has been concerned only with the moon. However it seems likely that within a decade we shall be able to measure the distances of the nearer planets and study their surfaces by this astronomical technique. This paper outlines what has already been achieved in the study of the moon and indicates some of the possible future results.

摘要:

When Oliver Cromwell's decision to place the Post Office under the control of Parliament was ratified by Charles II in 1660, the main business of the Post Office was communication—transmission of the written word by letter. Since these days the Post Office has become responsible for many other services, either on its own account, or as an agent for other Government Departments; communication, however, is still its main business, although many new forms of it have been added during the last hundred years.
