It is best explained in rap by MC Hawkings

Entropy
Trash Talk
Harm me with harmony.
Doomsday, drop a load on 'em.

Verse 1
Entropy, how can I explain it? I'll take it frame by frame it,
to have you all jumping, shouting saying it.
Let's just say that it's a measure of disorder,
in a system that is closed, like with a border.
It's sorta, like a, well a measurement of randomness,
proposed in 1850 by a German, but wait I digress.
"What the **** is entropy?", I here the people still exclaiming,
it seems I gotta start the explaining.

You ever drop an egg and on the floor you see it break?
You go and get a mop so you can clean up your mistake.
But did you ever stop to ponder why we know it's true,
if you drop a broken egg you will not get an egg that's new.

That's entropy or E-N-T-R-O to the P to the Y,
the reason why the sun will one day all burn out and die.
Order from disorder is a scientific rarity,
allow me to explain it with a little bit more clarity.
Did I say rarity? I meant impossibility,
at least in a closed system there will always be more entropy.
That's entropy and I hope that you're all down with it,
if you are here's your membership.

Chorus
You down with entropy?
Yeah, you know me! (x3)
Who's down with entropy?
Every last homey!

Verse 2
Defining entropy as disorder's not complete,
'cause disorder as a definition doesn't cover heat.
So my first definition I would now like to withdraw,
and offer one that fits thermodynamics second law.
First we need to understand that entropy is energy,
energy that can't be used to state it more specifically.
In a closed system entropy always goes up,
that's the second law, now you know what's up.

You can't win, you can't break even, you can't leave the game,
'cause entropy will take it all 'though it seems a shame.
The second law, as we now know, is quite clear to state,
that entropy must increase and not dissipate.

Creationists always try to use the second law,
to disprove evolution, but their theory has a flaw.
The second law is quite precise about where it applies,
only in a closed system must the entropy count rise.
The earth's not a closed system' it's powered by the sun,
so **** the damn creationists, Doomsday get my gun!
That, in a nutshell, is what entropy's about,
you're now down with a discount.

Chorus

Trash Talk
Hit it!
Doomsday, kick it in!

Entropy can be considered as the state of orderliness in the universe (and in any smaller closed system). For example if you have a pallet loaded with say 1,000 small blocks of wood stacked as an orderly large cube, you could take a snapshot of it and say that it posseses a certain random amount of "entropy." If the forklift carrying the blocks hits a wall and spills all the blocks, the orderliness is degraded and entropy increases. In fact it would take work to put all the blocks back together reducing its entropy to the original amount. However, the person putting the blocks together must breathe using up oxygen to burn sugars in the bloodstream to produce energy as well as water and carbon dioxide as waste products (which are less organized than the sugar being burned). Energy from the sun was used to grow the plants which produced the sugar. Conversion of hydrogen into helium by fusion in the sun was required to produce the light needed to grow the plant that produced the sugar.

In every case, energy must be expended to create greater organization, reducing local entropy. But the source of energy becomes less organized (and its entropy increases) in order to re-organize (and reduce the entropy) of a subset of matter within the system under consideration.

In a perpetual motion system, there would be no increase in entropy because it would remain organized and unchanged forever. Because of friction, there are no true perpetual motion systems known to man.

Consider the "Big Bang" that created the universe. How much energy would be required to force the universe back into its dot -sized singularity? Where in the universe would you get the energy? Hope that helps a little.

Entropy is the tendency for all matter to seek a state of lower energy, and thus more disorder.

Entropy itself is not increasing in the universe. It is a basic principle of how matter operates. What you may be thinking about is that disorder is always increasing. Ultimately (in billions of years from now) entropy will lead the the universe to end in a Little Fizzle, the culmination a long process since the Big Bang.

Unless of course, some other forces (gravity for example) halt the entropic process.

Entropy is randomness. with every change in universe the randomness keeps increasing. thats pretty easy to understand if we take an example like,,,,,,,,,,,, consider a process with 2 possible outcomes. when the process takes place the outcome is random among the 2..........and this outcome will lead to another process which has 2 random possible outcomes............... and so on...... now can anyone tell what the outcome will be on the 8th step for sure? no its probability......and probability exactly states the randomness involved.

if u wanna discuss more about it u can chat me on t_rex_boi@yahoo.com

Entropy is the tendency for everything to migrate toward randomness.

The real question is.... why is evolution differant?

Get a life! Does it really matter if you can understand it. If you have a wife or kids spend that time with them. Besides it is much more difficult to understand a woman.
