Crikey, no need to be cheeky. If you want me to start from Mickey Mouse engineering definitions then I shall:
The Second Law of Thermodynamics:
Hot Stuff gets Colder.
Heat flows spontaneously from High Temperature Bodies to Low Temperature bodies. There are 2 classical statements of this principle:
Clausius: No process is possible which only results in the transfer of heat from a colder body to a hotter one
Kelvin: No process is possible which only results in the absorption of heat from a resevoir and the conversion of all this heat to work.
We now need to define a new state variable, Entropy, S:
dS=dQ/T [where Q is Heat due to Reversible Processes, T temp]
I'm not going to waste my time by attempting to go further and type out he integrals concerned, suffice to say any decent undergraduate Physics textbook will then show that in any physical process the change in entropy is never negative.
Hence, the entropy of the universe is constantly increasing, and would eventually reach a maximum should an equilibrium be encountered. As entropy is a measure of the disorder in a system, I think I'm vindicated in saying that the universe will tend to chaos [utter confusion and DISORDER, see OED]. If you want to talk about Chaos Theory, as in Sensitive Dependence on Initial Conditions and all that malarkey, you're more than welcome. But it's not explicitly what I was referring to in my earlier post.
Now, rant over. I've not been ignoring you people, just haven't had time to post recently, things have been a bit, well, chaotic over here. I've not had time to read all the posts, although I have gleaned that things have been getting rather heated. No need really, is there? Anyway, I'll read through the stuff and get back to you Unconvinced et al ASAP.
Cheers
Nick
