Despite their apparent simplicity, the behaviour of pendulums can
be remarkably complicated. Historically, pendulums for specific
purposes have been developed using a combination of simplified
theory and trial and error. There do not appear to be any
introductory books on pendulums, written at an intermediate level,
and covering a wide range of topics. This book aims to fill the
gap. It is written for readers with some background in elementary
geometry, algebra, trigonometry and calculus. Historical
information, where available and useful for the understanding of
various types of pendulum and their applications, is included.
Perhaps the best known use of pendulums is as the basis of clocks
in which a pendulum controls the rate at which the clock runs.
Interest in theoretical and practical aspects of pendulums, as
applied to clocks, goes back more than four centuries. The concept
of simple pendulums, which are idealised versions of real pendulums
is introduced. The application of pendulums to clocks is described,
with detailed discussion of the effect of inevitable differences
between real pendulums and simple pendulums. In a clock, the
objective is to ensure that the pendulum controls the timekeeping.
However, pendulums are sometimes driven, and how this affects their
behaviour is described. Pendulums are sometimes used for occult
purposes. It is possible to explain some apparently occult results
by using modern pendulum theory. For example, why a ring suspended
inside a wine glass, by a thread from a finger, eventually strikes
the glass. Pendulums have a wide range of uses in scientific
instruments, engineering, and entertainment. Some examples are
given as case studies. Indexed in the Book Citation Index- Science
