An informal and highly accessible writing style, a simple treatment
of mathematics, and clear guide to applications have made this book
a classic text in electrical and electronic engineering. Students
will find it both readable and comprehensive. The fundamental ideas
relevant to the understanding of the electrical properties of
materials are emphasized; in addition, topics are selected in order
to explain the operation of devices having applications (or
possible future applications) in engineering. The mathematics, kept
deliberately to a minimum, is well within the grasp of a
second-year student. This is achieved by choosing the simplest
model that can display the essential properties of a phenomenom,
and then examining the difference between the ideal and the actual
behaviour. The whole text is designed as an undergraduate course.
However most individual sections are self contained and can be used
as background reading in graduate courses, and for interested
persons who want to explore advances in microelectronics, lasers,
nanotechnology, and several other topics that impinge on modern
life.
Metamaterials is a young subject born in the 21st century. It is
concerned with artificial materials which can have electrical and
magnetic properties difficult or impossible to find in nature. The
building blocks in most cases are resonant elements much smaller
than the wavelength of the electromagnetic wave. The book offers a
comprehensive treatment of all aspects of research in this field at
a level that should appeal to final year undergraduates in physics
or in electrical and electronic engineering. The mathematics is
kept at a minimum; the aim is to explain the physics in simple
terms and enumerate the major advances. It can be profitably read
by graduate and post-graduate students in order to find out what
has been done in the field outside their speciality, and by experts
who may gain new insight about the inter-relationship of the
physical phenomena involved.

Getting the Message is a unique and engaging exploration of the
fascinating history of communications, starting with ancient
civilisations, the Greeks and Romans, then leading through the
development of the electric telegraph, and up to the present day
with email and smartphones. The technology is explained in a
particularly simple and accessible way, and themes from politics,
economics, and society weave in and out of the scientific ideas.
The book concludes with a look at the possible future of
communications, the new developments to come, and the implications
these will have for our everyday lives. Lavishly illustrated, and
including many original illustrations that show just how these new
developments were received in their time, the book presents an
informative and highly entertaining introduction to the field of
communications. This revised second edition looks at the new
developments in communications over the two decades since the first
edition's release.

These plays cover one thousand years of the ancient world from the
golden age of Athens to 5th century Alexandria. The protagonists
are Anaxagoras, Archimedes and Hypatia, scientists, mathematicians,
philosophers. All three of them came into conflict with the
prevalent views of the time. Anaxagoras maintained that the sun was
a big burning rock of the size of the Peleponnesus. He was
condemned to death on the charge of impiety. Archimedes, the first
example of the efficacy of technology combined with science, built
fortifications that could withstand the might of the Roman Army.
His popular fame rests on him shouting Eureka and jumping naked out
of his bath when he discovered the laws of Hydrostatics. He is also
known by his statement: 'give me a fixed point and I shall move the
Earth.' Hypatia was a philosopher and mathematician, a believer in
the old faith. She was hacked to death by a bunch of monks at the
instigation of Cyril, a Saint of the Christian Church.
Geniuses are few and far between. Most of them will have honors and
prizes showered upon them. But there will be exceptions, numerous
exceptions: We don't know how many because they never make it; they
fall by the wayside. They believe themselves to be alone in a
hostile world, unable to adapt, unable to bring their ideas to
fruition. They detest their inferiors and detest even more their
superiors. One such genius, a historian with acute observations
about the past and the future, was immortalized by Ibsen in his
play Hedda Gabler. The Portrait of a Genius tells a similar story.
Dramatis personae are the following: Helen Gascoigne, young,
beautiful, uncompromising; Leslie Brock, the dean of the faculty
who wants to bed her; George Turner, Helen's devoted husband, a
scientist not burdened with great leaps of imagination; Esmund, the
reckless genius who invents an entirely new kind of computer; and
finally, Rosalind, girlfriend and admirer of Esmund.
Assassination of prominent people occurred in all countries at all
times over the history of mankind. They are not random events in
the sense that there is always a motive behind them. In our
analysis we shall more or less adhere to the following criteria:
(i) The victim must be a public personage, (ii) The assassination
must be premeditated, (iii) It must be done by stealth, (iv) There
must be a motive and (v) The assassin aims only at the death of the
person selected. In Part I we give a chronology of all major
assassinations from biblical times onward. The number of
assassinations in any particular year may often be seen to bear
some strong correlation with the historical events unfolding. There
is actually a year, 1934, that presages most major conflicts in
Europe. Part II contains brief biographies of both victims and
perpetrators. It is not unusual that he who arranges an
assassination will be assassinated in his turn. As stated in
Matthew's gospel: 'They that take the sword shall perish with the
sword.' The various categories of assassinations are discussed in
Part III together with definitions and classifications and with
descriptions of historical periods dominated by assassinations, as
for example the French Wars of Religion.
