I was drawn to this preprint, not because I found it fascinating (it is, in some way, after I started reading it), not because I'm interesting in raindrops, and not because I've been pondering about the falling raindrops problem before it is "revisited". No, the reason why this article attracted my attention was due to the name of the author - Alan D. Sokal.
Yes, that would be the same Alan Sokal of the infamous Sokal Hoax of several years ago. I'm not going to deny that when he did that and the proverbial feces hit the ceiling fan, he automatically became my "hero". :)
So this is another opportunity to mention this "event" and to point out the link in case you have not been aware of it.
