:::::Also, I've had students throw the second law of thermodynamics at me when I'm trying to explain evolution. The Earth's surface isn't a closed system either because it's constantly receiving energy from the sun--so the second law of thermodynamics is inapplicable there as well. The only truly closed system that I can think of is in Washington...and, yes, entropy there is ''always'' increasing! --[[User:RudrickBoucher|RudrickBoucher]] 09:05, 9 January 2012 (EST) | :::::Also, I've had students throw the second law of thermodynamics at me when I'm trying to explain evolution.
