Since I've said so many contrary things in response to David already, I'll first just say that I rather liked this article.-I did have a couple of minor quibbles with it, but nothing major:-1) It could be generalized to all sciences and while the focus on physics is perfectly appropriate given the author's position, I would have liked for that to at least have been noted.-2) I don't know who all the author expected their audience to be, but they seem to have failed to consider how their words might be misconstrued. It's a bit light on pointing out that the "hastily erected shanty-town" isn't a weakness, that's just how science works.
