    His headmaster said he would never make a success out of anything, he was expelled from school at the age of 15, and the only way he could get a job was by a friend pulling some strings behind the scenes. Such was the inconspicuous start Albert Einstein made to a brilliant career in science. The advances he was to make over the next 60 years can be matched only by those of Newton two centuries before, and his theories of relativity shook the very foundations of 20th century science. He challenged the absoluteness of space and time in his papers of 1905 (when he was only 26), and his General Theory of 1915 still forms the basis of our current understanding of gravitation

Bit-slice microprocessors—their use and application in minicomputers

    Although the effort necessary to develop an effective bit-slice-microprocessor microprogrammed design initially seems significant, the benefits far outweigh the investment. After microprogramming techniques are developed, new applications become much easier to accomplish. Although a designer may have to learn new methods, once mastered, a very powerful design tool can be applied to solving complex data processing or control communication systems

    ‘As technologies converge, the industries based upon them inevitably collide’, as a recent E&P ‘Focus’ article said.* No current technological development is likely to shape our future as much as the convergence of the semiconductor and computer technologies, and this convergence is now inevitably leading to a very real collision between the semiconductor companies and the established computer industry. This collision is shown most clearly by the introduction of minicomputer-like 16-bit ‘supermicros’, which are bringing the semiconductor and minicomputer companies into direct competition. However, this development is just part of the far-reaching confrontation between the two industries

    The microprocessor industry is now showing signs of maturity as the methods by which microprocessor-based products are developed are becoming clearly defined. This article is intended to emphasise the need for the correct tools to be used in development. Serious professional work with a microprocessor needs to be undertaken with a healthy understanding of the risks and pitfalls. The author and his colleagues are nearing the completion of a project in which development aids have been studied by in-depth laboratory evaluation. This work shows that a great deal of time and money can be wasted without prudent choice of the correct tools. This article describes the parts of these tools which it is important to evaluate. Microprocessor product development is highly labour intensive and the engineers with the right knowledge and experience are at the moment rare and expensive. It is important therefore to use equipment that is quick and efficient in order to deploy these engineers effectively

    The perinatal death rate is still too high. For every 1000 deliveries in England in 1975, there were 19 deaths during the period between the start of labour and the seventh day of life. Eight of these deaths occurred after birth. All work towards lowering the risk is of benefit, and may contribute to the gradual decline in perinatal mortality that has been seen since records began

    The explosive growth of the use of the microcomputer, involving many automated processes now done partly or wholly by hand or by earlier automatic systems, will greatly influence the qualities required of those people working with such systems. Many traditional skills will be supplanted; others will be required. With this scenario, we must radically rethink how we educate children, especially those not destined for higher education and, of equal importance, how we should retrain our existing work force

    ‘Light rapid transit’ is essentially an upgraded tramway; in the popular idiom it is a ‘supertram’. It is often developedon the basis of a conventional electric tramway, it generally operates on its own segregated right of way, and it incorporates up-to-date equipment based on proven and accepted technology, but without necessarily incurring all the costly system in on the middle ground: betweeen the ordinary street-running transport mode(the bus) and the fully-equipped rapid transit system (the London Underground)

    Edison's work on electric lighting, which shaped the future of the whole electrical industry, was guided by one clear aim: ‘to effect [an] exact imitation of all done by gas, to replace lighting by gas by lighting by electricity’. The early development of the electrical industry was based on the simple strategy of using the superiority of the electric lamp to drive the gas companies out of the highly profitable lighting market. For over a decade this strategy worked, but then the gas companies hit back with a new form of gas lighting that neatly turned the tables on the electric lamp. This new threat to electrical development delayed the final triumph of the electrical industry for nearly 20 years
