Entropy

This is from The Elegant Universe:

[P]hysicists have given a fully quantitative definition to entropy [a measure of disorder or randomness] by using a definite numerical value: Larger numbers mean greater entropy, smaller numbers mean less entropy. Although the details are a little complicated, this number, roughly speaking, counts the possible rearrangements of the ingredients in a given physical system that leave its overall appearance intact. When your desk is neat and clean, almost any rearrangement […] will disturb its highly ordered organization. This accounts for low entropy. On the contrary, when your desk is a mess, numerous rearrangements of the [stuff] will leave it a mess and therefore will not disturb its overall appearance. This accounts for high entropy.

The above was posted to my personal weblog on May 17, 2003. My name is Peter Lindberg and I am a thirtysomething software developer and dad living in Stockholm, Sweden. Here, you’ll find posts in English and Swedish about whatever happens to interest me for the moment.
