The second law is not derived from quantum mechanics as the current introduction suggests, it may be better to refer to statistical mechanics.
 
The second law is not derived from quantum mechanics as the current introduction suggests, it may be better to refer to statistical mechanics.
 
It may be better to put a bit more emphasis on the statistical nature of the law, that entropy can decrease in a closed system, but it is extremely unlikely, so not observed for all practical purposes. [[User:Richardm|Richardm]] ([[User talk:Richardm|talk]]) 09:42, 25 September 2016 (EDT)

:This is not a scientific statement: "entropy can decrease in a closed system, but it is extremely unlikely, so not observed for all practical purposes."  Statistical mechanics is a primitive, pre-[[quantum mechanics]] approach that leads some to make non-scientific claims, like the quoted one.

:I will add "in the absence of intelligent intervention" to "This principle correctly predicts that heat will never flow from a cold body to a warmer one," although it is already implied.--[[User:Aschlafly|Andy Schlafly]] ([[User talk:Aschlafly|talk]]) 15:32, 25 September 2016 (EDT)
