Many thanks to Dennis for linking, from the NYT site, an article I wrote one year ago to comment a crackpotty paper by an otherwise esteemed scientist.
The essay just appeared on the New York Times
site is excellent, as always with Overbye, but it is also way more balanced than my rather vitriolic attack on the theory of backward causation and, in particular, the idea that one should use the Large Hadron Collider to test it by deciding to run or not to run based on the turn of a card.
The web site of the Cornell preprint archive, arxiv.org, says it best: successful submissions to the preprint archive are a source of considerable pride (darn it, the page with the exact statement is only available just after you submit a paper, so I cannot quote it literally here since my browser has by now forgotten it!).
Ah, the pleasure of study! I had forgotten the immense intellectual pleasure one may derive by reading a stimulating, informative book. And if half a lifetime has passed from the last time you studied something, and what is left in your brain of it is just Culture, then reading it back again combines the pleasure of the discovery (a rediscovery, in this case) with the one of putting things in perspective, combining the bits of information you recollect with all the knowledge you have acquired since the last time you put the book down.
