Thus spake Tom Carter circa 10/14/2009 11:30 PM: These days, most mathematicians are so comfortable with associativity that they'll go ahead and include that as part of the definition (of, e.g., a geometric algebra) . . . and then also they won't have a bunch of theorems that start out, Let

[FRIAM] synthetic black holes

So yesterday I'm reading about solar energy and thinking -- blah, blah, blah -- of all the known solutions. Today Slashdot gives me a blurb about synthetic black holes, which I follow to new scientist and on to http://arxiv.org/abs/0910.2159v1 The abstract: Traditionally, a black hole is a
