[Intro] 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 jump and shout and 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 f** is entropy?", I hear 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 f** the damn creationists, Doomsday get my gun That, in a nutshell, is what entropy's about You're now down with a discount [Chorus] [Outro] Hit it! Doomsday, kick it in!
