My old friend Dan Vergano wrote an article in USA Today the other day about the irrational fears over the Large Hadron Collider. It's a pretty good collection of the silliness that's gone on from people who think the LHC will destroy the world (and it has a brief list of a few other fizzled doomsday scares).
It's a pretty even-handed and rational response to the doomcriers. That's good, because my own inclination is to mimic Brian Cox's response.
Tip o' the tin foil beanie to ... my mom, who told me about this article.
