no. you should specify

It really isn't trivial to compute on paper without simulation

But it doesn't.

If I see one more dumbass think that wavefunction collapse is some kind of esoteric thing that has to do with consciousness I really will scream.

>what is entropy
Basically, it is the internal energy of a system that cannot be used to do work. Classically, entropy is a state function--which means it is a variable is path independent-- that satisfies
[eqn]\Delta S=\int\frac{\delta Q}{T}[/eqn] which basically says the change of entropy of a system during some kind of thermodynamic process is equal to the sum of the tiny increments of heat that flow into the system from its surrounding divided by the current temperature.
If you ask a stat mech fag, he will tell you that entropy is proportional to the sum of probabilities of microstates times the log of blahblahblah which turns out to be equal to the log of the number of micro-states within a system. Or [math]S=k_b\log\Omega[/math].
In practice, you lookup entropy on a table that has been compiled with lots and lots of experimentation.
>What is the energy that is contained within a piece of wood? Does it just come from the binding energies between the atoms?
This is pretty vague. But the energy that comes from a piece of wood when you burn it does come from the energy stored in chemical bonds. Yes.
>lets say I have a 10x10 block of wood, what is its energy?
I don't know how big a 10x10 block is.
