I admit that I am a bit behind on my reading.  I usually read when I travel, but I haven’t been traveling as much this year, so I’m behind on my reading.  There’s really no point to me telling anyone this, other than I guess I feel guilty when I find something interesting that I want to blog about, but realize that the information is a few months old.  So – I guess I’m saying that I know that you may have already seen this, and, yes, I am a bit behind, but, no, I hadn’t heard about it, so I am blogging about it now.  Besides, how many advertising people are reading the New Journal of Physics anyway?
