摘要:

A lecturer to first year undergraduates in Manchester in 1952 fell sick and the Head of Department, the late Sir Frederic Williams, decided to give the lecture in his place. He asked me to demonstrate for him.

摘要:

The Scottish Higher Grade Physics syllabus has recently been altered to include some detailed work on photodiodes. This article is from the Scottish Schools Equipment Research Centre (SSERC) to assist teachers in Scotland in introducing the topic. We include this article as we feel that it has a wider use for older students. Many of the techniques described would make good (and cheap!) practical investigations for ‘A’ level physics and electronics students. Much of the data described will be invaluable to those doing project work in electronics.

摘要:

During last year the Editorial Board decided to feature articles and projects suitable for 11–13 year olds. This I hope will be the first of many, perhaps teachers could share their projects with others in the form of an article, or if any of you have a project idea that you would like the Editorial team to develop, please contact us.

摘要:

Technological change and innovation can occur either through haphazard discovery or through focused research and development. The occurrence of innovation by chance is particularly apparent in basic research. Oersted discovered the relationship between electricity and magnetism as he happened to hold an electric wire parallel to a needle during the course of a lecture. Galvani, a physiologist, noticed that a frog's legs contracted due to the generation of an electric spark when they were left hanging on a set of different metals. Oersted's observations led to the development of the dynamo. Galvani's observations led to the development of the electric battery. At the present time technological innovation has become increasingly institutionalised through corporate, university and governmental research programmes.

摘要:

In previous articles {Electronics Education Spring 1991 and Autumn 1991), I discussed the need for control programming languages to be compatible with the educational aims of teaching computer control. One technique for structured problem-solving, which I did not dwell on then, is ‘top-down-development’. With the launch of some new ‘languages’ at BETT92, now is an appropriate time to consider this issue.

摘要:

The article titled ‘Useful circuits’ in the Spring issue would be incomplete without considering how the circuits could be assembled. Every teacher of science or technology using electronics has a method of construction that they are comfortable with. There are three methods that we consider to be appropriate for student use.

摘要:

I'm rushing along in a train at minus 100 miles per hour. Minus 100? I need to think about that. Through the window I can see the lampposts flicking backwards—or do I mean forwards? I suppose I mean both. Travel these days is so boring… that's why I like to take lots of little breaks. (I'm sorry that's a play on words, but you probably won't get it till later) MINUTE'S UP — HOP!
