    Did I say that? When? Do you have a link – I’ve answered rather a few questions now so having trouble finding it.

    Hi there, if you want a good introduction to exactly what it is I can recommend this wikipedia article:
    http://en.wikipedia.org/wiki/Introduction_to_entropy

    No point me re-writing it here but if you have any more questions afterward feel free to ask :-)

    Thanks for your questions by the way, they’ve been great!

    I like to think of it as “chaos” and whether or not something is reversible….like you can never ‘unfry’ an egg.

    It’s more specifically a measure of the amount of energy that isn’t being used for anything useful, such as a mechanical approach. It’s associated sometimes with disorder, but it’s not a measure of it.
