Thanks once again to Jolaine Incognito for:
a) subscribing to Scientific American!
b) sending me a link to something cool!
Seems like Maxwell’s demon is alive and well and featured in Scientific American this month. The thought experiment is being used to look for ways to cool molecules to near Absolute Zero (Tee hee, “near absolute”.).
Read more about it here: http://www.scientificamerican.com/article.cfm?id=demons-entropy-and-the-quest (Sorry, you have to subscribe to get the whole article.)
There’s a cool animation about it here.
