Some time ago the intellects at the Perimeter Institute who rightly used to call themselves "today's Einsteins" started cooking "souffle of particles with gravity" but someone must have explained to them how dangerous that was and now it is not clear what they are cooking. Just in case, they don't call themselves "today's Einsteins" anymore: http://maisonneuve.org/index.php?&page_id=12&article_id=2934 "CRISES + PARADOX = REVOLUTION. WELCOME TO THE PERIMETER INSTITUTE WHERE TODAY'S EINSTEINS ARE HARD AT WORK. It's lunchtime at the Black Hole Bistro, an in-house restaurant at Waterloo's Perimeter Institute for Theoretical Physics. Amid the mounting clatter and chatter, conversation at a corner table moves from one universal subject to another: from the questionable authenticity of the buffet chicken to the union of quantum mechanics and general relativity. The marriage of these two theories of the universe-incomplete on their own, but incompatible with each other-is the coveted Rosetta stone of physics. Quantum theory pertains to things on a very small scale, such as particles; it's important for the study of chemistry and atomic physics. Relativity pertains to the very large, such as gravity; it's important for the study of astronomy and cosmology. A successful souffle of particles with gravity, so to speak, would amount to nothing less than the "theory of everything"......." Pentcho Valev pvalev@yahoo.com
