Galileo, Newton, Watt: they were geniuses, all
Without them we'd be freezing in the dark at the mall
James Joule found total energy remains the same,
(no matter what its form) that's why it carries his name

Chemical, electrical, potential and heat,
Radiant, kinetic, ooh the list is incomplete,
They're always changing back and forth it's really quite a blur,
(Oh how could he) I've forgotten nuclear!

Ride a barrel down the falls,
Then cook spaghetti with meatballs,
Really make your friends amazed,
Nuke it with some gamma rays,

Fly to Venus in a rocket,
Put your finger in a socket,
You may suffer from exhaust
But none of that energy is ever really lost!

Then why can't we make a clean machine that moves perpetually?
'Cause there's another law with which all energy must agree:
Whenever it changes form it loses quality,
(In other words) Damn that rising entropy!

It's entropy you see that turns finesse to mess,
A palace to a pig sty, why it's simply scandalous,
Energy once neat degenerates into waste heat,
(We must repeat) Because of entropy!
