Diluting Felicia

It's not hard to describe just how silly homeopathy is -- after all, diluting a substance in water until nothing is left is clearly not a great way to base a medicinal practice. Unless you're trying to cure dehydration. But if describing homeopathy's silliness is easy, doing it well is another matter; most people don't have a very good sense of scale when it comes to very big and very small numbers (I guess numbers that dwarf even a trillion weren't necessary for our ancestors on the plains of Africa, so we never evolved a way to grasp them). However, Steve DeGroof at MadArtLab (the same guy who does the skeptic web comic Tree Lobsters) has found a way to put homeopathy into perspective: use Felicia Day!
