D. who has been working as an economist here in New York for many years, and someone I&#8217;ve often enjoyed talking to over the years.  Going back to his days as a graduate student, he has been working on some of his own far out of the mainstream ideas about geometry and physics (which I&#8217;ve never seen the details of).  Eric has finally gotten to the point where he is willing to talk about these ideas publicly, and he is giving a <a href=\"http:\/\/www.simonyi.ox.ac.uk\/simonyi-lectures\/special-simonyi-lecture-2013-eric-weinstein\">lecture today in Oxford<\/a>, something that was arranged by Marcus du Sautoy.  The Guardian has a long article about him and his work <a href=\"http:\/\/www.guardian.co.uk\/science\/blog\/2013\/may\/23\/roll-over-einstein-meet-weinstein\">here<\/a>.<\/p>\n<p>There&#8217;s a bit of an analogy with the Garrett Lisi physics outsider story here, although I think Eric will get less media attention since he doesn&#8217;t have the surfing angle going for him. Both he and Garrett are pursuing what seems to me one of the deepest questions around: what is the relationship between the SU(3)xSU(2)xU(1) geometry of the Standard Model, and the 4d pseudo-Riemannian geometry of space-time and general relativity?  Garrett was trying to understand this in terms of E(8) symmetry, and I&#8217;m looking forward to seeing what Eric&#8217;s ideas about this are. I&#8217;m not sure when he&#8217;ll have a paper out on the arXiv, or whether some sort of version of his lecture will be available.<\/p>\n<p><strong>Update:<\/strong>  The Guardian now has a <a href=\"http:\/\/www.guardian.co.uk\/science\/2013\/may\/23\/eric-weinstein-answer-physics-problems\">very enthusiastic article<\/a> about this by Marcus du Sautoy, while New Scientist has a skeptical take <a href=\"http:\/\/www.newscientist.com\/article\/dn23595-weinsteins-theory-of-everything-is-probably-nothing.html\">here<\/a>.<\/p>\n<p><strong>Update<\/strong>: See <a href=\"http:\/\/blogs.scientificamerican.com\/cocktail-party-physics\/2013\/05\/24\/dear-guardian-youve-been-played\/\">Jennifer Ouellette<\/a> for a critical take on the Guardian coverage.<\/p>\n<p><strong>Update<\/strong>: It seems that claims that physicists were not invited to Weinstein&#8217;s talk are not true: an announcement and posters were sent to the physics department, but did not get widely disseminated.
