Two weeks of fancy physics

Two intensive weeks of physics of black holes are over. This year the Michigan Center for Theoretical Physics in Ann Arbor organized the "Black Holes in String Theory Workshop" which I attended. It was a very productive meeting in which most of the discussions and talks were on black holes, fuzzballs and entanglement.

Back in Cambridge on Friday I attended the Harvard Physics Postdoc Retreat which I was also co-organizing. Postdocs from all the areas of the Physics Department gave 10 minute presentations. And aside from a lot of delicious food we had also break-out (interaction) sessions and, a great trivia "science" game also scheduled for the day. Stephen Wolfram was the special guest at the Retreat's dinner (see pic below). In spite of saying that he did not remember any female physicist working in his team or that nowadays he is hiring more IT-graduates than physicists, hearing about his experience as entrepreneur was extremely interesting. In all, the meeting was a success and we are all now looking forward to the 2014 edition!

Meanwhile at Harvard ... the last two speakers at our High Energy Theory Group Journal Club were Paul Chesler "On the instability of asymptotically AdS spacetime" and Douglas Stanford telling us about "Black Holes and Butterfly effect" based on http://arxiv.org/abs/arXiv:1306.0622.

A week of prizes in theoretical physics

This past week, not only the Sakurai Prize for Theoretical Particle Physics was awarded but just yesterday the Nobel prize in Physics, for "the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles", was announced.
The main difference in the prizes is the money involved! Last week I visited CEA-Saclay and during after lunch coffee I met Kosower, whom was very happy for the receipment of this year's Sakurai prize, and he mentioned that the prize was U$D10.000 divided by three (the number of awardees). In contrast, the Nobel prize in 2013 is U$D 1.235million (to be divided between Englert and Higgs).
The Nobel prize in physics -- that can only be awarded to at most three people -- this year is also somehow controversial. While the Sakurai prize for the "Higgs boson" was awarded in 2010 to the six authors of the symmetry breaking Physical Review Letters (PRL) paper saga of the summer of 1964, the Nobel committee left out the three authors on the last paper of the discovery. Let me remind you that the first paper was submitted by Englert and Brout (who passed away in 2011 and hence could not be awarded the Nobel prize). Then Higgs submitted his paper on Aug. 31 1964 and, 48 days later, Guralnik, Hagen and Kibbles submitted their paper to PRL (for more details you can browse an older post on my blog) which was published a month later.
There are also a lot of expectations regarding a Nobel prize for next year which is expected to be for the experimental discovery of the Higgs@CERN that this year was also not recognized.
In spite of all the drama and tension it is great to see that theoretical physics gets also a lot of recognition!

Before finishing my post let me just mention we had Thomas Dumitrescu at the High Energy Journal Club at Harvard telling us about "On Scale and Conformal Invariance in Four Dimensions" based on http://arxiv.org/abs/1309.2921
