Booth, Andrew Donald Booth, Andrew Donald<br />
College were introduced to the world <strong>of</strong> computers<br />
much earlier than others studying numerical methods<br />
and, as a consequence, were <strong>of</strong>ten subjected to much<br />
less <strong>of</strong> the drudgery <strong>of</strong> hand computation than their<br />
contemporaries.<br />

This short paper describes two analog machines <strong>of</strong> use<br />
in the analysis <strong>of</strong> crystal structures. The first is rather<br />
specialized, but the second is a simple device for<br />
summing cosines.<br />

This is a very early work on electronic computers.<br />
After an simple introduction to mechanical calculating<br />
machines and a description <strong>of</strong> their electronic equivalents,<br />
it discusses the design <strong>of</strong> a computer and how it might be<br />
implemented using electronics. By this time the Booths<br />
had acquired considerable experience with the creation<br />
<strong>of</strong> different types <strong>of</strong> memory devices. This experience is<br />
shown in the very well-developed section on computer<br />
memories, ranging from mechanical devices invented by<br />
the Booths (see illustration), through magnetic drums, to<br />
delay line and electrostatic memory devices. They even<br />
have a small section on magnetic core memory and an<br />
aside that implies that they had been thinking about thin–<br />
film plated memory. The book finishes with a discussion
