  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:

  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.
