Glossary of Physical Terms used in the Poems

Entropy: Entropy can be thought of as a measure of the disorder of some system of particles - and remember almost everything can be described as a system of particles called atoms. By disorder we mean something without any discernable pattern. E.g. a crystal has a high degree of order whereas a gas does not. In a 'closed' system of particles, i.e. one in which neither energy nor particles can be gained or lost, the system always tends towards a state of maximum entropy, or in simple language, 'maximum disorder'. The universe itself is thought to form a closed system and it could be said that we are all hurtling towards an oblivion of total disorder!
