Nature is a book one can read, but the language is mathematics.
The day Galileo Galilei discovered the law of the pendulum, I’m sure he thought he was reading the book of nature, and when I play my pendulums I sometimes have a similar feeling. I can not control their movement and can only try to follow their rhythm, their natural rhythm. The law of the pendulum is only one among thousands of laws that control the world we live in, not counting those yet undiscovered, but it is a natural law that can be seen and heard rather easily, and often people who attend performances of Galileo also feel that they are not only hearing music, but also reading a bit from the book of nature.
a composition/instrument that swings on five pendulums. The slowest of
these hangs from a line about 260 cm long, suspended from a height of
about four meters. The other four pendulums must be carefully measured,
following the formula discovered by Galileo Galilei some 500 years ago,
so as to make their cycles in 1/2, 2/3, 3/4, and 4/5 the time necessary
for the longest. A sequence of short compositions allow us to hear all
the different combinations of tempos. The piece has evolved slowly from
three pendulums to five, from 10 minute to over 40, in a variety of
