This is possibly because I really believe that Homeopathy works, just like placebos. I am reminded of the conversation in "The Simpsons". Homer Simpsons panics after seeing one bear and gets the mayor to have a bear patrol. Then,
Homer: Not a bear in sight. The Bear Patrol must be working like a charm. Lisa: That's specious reasoning, Dad. Homer: Thank you, dear. Lisa: By your logic I could claim that this rock keeps tigers away. Homer: Oh, how does it work? Lisa: It doesn't work. Homer: Uh-huh. Lisa: It's just a stupid rock. Homer: Uh-huh. Lisa: But I don't see any tigers around, do you? [Homer thinks of this, then pulls out some money] Homer: Lisa, I want to buy your rock. [Lisa refuses at first, then takes the exchange]
Anyway, back to the paper. Homeopathy believes, contrary to all scientific evidence and thought, that potency increases with decrease of concentration. Thus "medicines" are sold at various dilutions from 1c to 200c. The paper discusses the procedure and concludes, "Further, we have shown that despite large differences in the degree of dilution from 6c to 200c (10^12 to 10^400), there were no major differences in the nature of the particles (shape and size) of the starting material and their absolute concentrations (in pg/ml)." All it means that no dilution really occurs beyond 6c.
