shnood: (roughly) an imposter; a person oblivious to just how trivial or wrong his ideas are.
â€œWere there any interesting speakers at the conference?â€
â€œNo, just a bunch of shnoods.â€
â€œThe magazine New Scientist loves to feature shnoods on the cover.â€
Note: someone whoâ€™s utterly contemptible would not be a shnood, but rather a schmuck.

Those of you interested in the way the Wobosphere functions as a disputation arena (“We Can Fact-Check Yo’ Ass!”) may be interested in the following sordid tale of intrigue and skullduggery. I originally wrote most of this last October, in a lengthy comment on David Brin’s blog. The moral of the story, insofar as I can find one, is this: if you say that you can move your car forward by bouncing a soccer ball back and forth inside it fifty thousand times, you’ll get a quizzical look (at best). If you say the same thing but with “microwave photons” instead of soccer balls, you’re reporting on cutting-edge science!
Back in September, New Scientist magazine published an article on the “EmDrive”, a machine purportedly able to propel itself using microwaves bouncing inside a box. Those of us who remember the Dean drive and umpty-ump other wonder machines have no trouble recognizing this as the same old stuff: like all the wonder-powered spacedrives before it, it can only putter forward by violating the conservation of momentum. New Scientist‘s reportage provoked science-fiction writer Greg Egan to write an open letter saying he was “gobsmacked by the level of scientific illiteracy” the magazine showed.
So it goes, as they say on Tralfamadore. Claims of exotic spacedrives fuelled by violations of fundamental physics are, sadly but understandably, about twopence a dozen. The aspect of the affair which Egan found truly disturbing — indeed, reprehensible — was the way New Scientist glibly provided a “news” piece full of pseudoscientific gibberish purely to justify how the EmDrive might work. (Their argument really pushed the limits of the absurd, too: Einstein’s relativity has momentum conservation built into its mathematical structure, so you can’t use relativity jargon like “reference frames” to sidestep the conservation law.)
Egan posted his letter to the moderated Usenet group sci.physics.research, and the physicist John Baez put a copy on the blog he co-hosts, The n-Category CafÃ©. This spurred enough people to write New Scientist that the magazine opened a blog thread to discuss the issue, opening with a self-exusing note from the editor, Jeremy Webb. (Said note, as far as I can tell, satisfied nobody.)
