The problem of the relation between our bodies and our minds, and espe cially of the link between brain structures and processes on the one hand and mental dispositions and events on the other is an exceedingly difficult one. Without pretending to be able to foresee future developments, both authors of this book think it improbable that the problem will ever be solved, in the sense that we shall really understand this relation. We think that no more can be expected than to make a little progress here or there. We have written this book in the hope that we have been able to do so. We are conscious of the fact that what we have done is very conjectur al and very modest. We are aware of our fallibility; yet we believe in the intrinsic value of every human effort to deepen our understanding of our selves and of the world we live in. We believe in humanism: in human rationality, in human science, and in other human achievements, however fallible they are. We are unimpressed by the recurrent intellectual fashions that belittle science and the other great human achievements. An additional motive for writing this book is that we both feel that the debunking of man has gone far enough - even too far. It is said that we had to learn from Copernicus and Darwin that man's place in the universe is not so exalted or so exclusive as man once thought. That may well be.

<p>So much has been written about the scientific contributions of Sherrington that the man himself, and his thoughts, have been overshadowed. More and more, students of history are calling for creative writing on the whole man, particularly when he is a genius. Those interested in the genesis of ideas want to know the settings for discoveries and the relevant circumstances which ushered in new truths and new insights. The "prepared mind" which Pasteur saw as the only one to be "favoured by fortune" is of immense importance in science, and our account of Sherring ton, we hope, will fill a very real gap in this field. During his life Sherrington actively discouraged any sugges tions that a biography be written. For that reason it was not until 1947 that there were any biographical notes by John Fulton, Graham Brown and A. D. Ritchie in a number of the British Medical Journal commemorating his ninetieth birthday, and in addition there was a leading article entitled "The Influence of Sherrington on Oinical Neurology". He left no autobiographical material except the few pages of reminiscences entitled "Mar ginalia", an essay written in honour of Charles Singer (1953).</p>

Semiconductor device modelling has developed in recent years from being solely the domain of device physicists to span broader technological disciplines involved in device and electronic circuit design and develop­ ment. The rapid emergence of very high speed, high density integrated circuit technology and the drive towards high speed communications has meant that extremely small-scale device structures are used in contempor­ ary designs. The characterisation and analysis of these devices can no longer be satisfied by electrical measurements alone. Traditional equivalent circuit models and closed-form analytical models cannot always provide consis­ tently accurate results for all modes of operation of these very small devices. Furthermore, the highly competitive nature of the semiconductor industry has led to the need to minimise development costs and lead-time associated with introducing new designs. This has meant that there has been a greater demand for models capable of increasing our understanding of how these devices operate and capable of predicting accurate quantitative results. The desire to move towards computer aided design and expert systems has reinforced the need for models capable of representing device operation under DC, small-signal, large-signal and high frequency operation. It is also desirable to relate the physical structure of the device to the electrical performance. This demand for better models has led to the introduction of improved equivalent circuit models and a upsurge in interest in using physical models.
