Here is an announcement of a program I will be organizing at the KITP from Jan 17 thru March 9 2012. It is a program on numerical methods for gravity and QFT. The web page of the program is located here.

Here is the image I made to illustrate the program: it is generated by taking a set of modes in a box with a UV cutoff. Then amplitudes are seeded for these modes with random numbers and phases multiplied by the typical quantum uncertainty on each mode. The result is a picture like the one below.

It is also fun to animate it.

Right now I have to start chasing people and reminding them that the (first) deadline for applications is coming soon (April 30th).

In the meantime stay tuned.

This is a short announcement that the West Coast LHC meeting is going to be taking place in Santa Barbara, on April 15th 2011. Here is our website:

WCLHC meeting 2011.

As you can imagine we have been busy at UCSB putting this together.

I have been enjoying the hospitality of the Simons Center for Physics and Geometry these past two weeks. I have been attending the workshop on Mathematics and Physics that has been going on yearly for the past few years.

It is a fun filled event where there is about one talk per day (on most days) and where I get to have a lot of conversations with very many people that I don’t see all that often.

The most interesting day of the week is when we have a seminar at the beach. We get together and drive away for about an hour to reach Smith Point Park. We then get to hear a whiteboard talk from some participant under a tent while the rest of the passer-byes gawk at  us: the idea of going all the way to the beach to hear someone speak about physics just floors them.

There are some pictures about those events that you can find in the webpage of the workshop, so you can go there to have a look (if you really must).

Perhaps because of my sense of humor, I kind of imagine us as a flock of kids who suddenly find themselves without their toys: the laptops are missing and we have to have `fun’ without doing calculations. Such activities involve tanning, getting in the sea and riding the waves, walking on the beach and perhaps even play volleyball.

All in all I definitely recommend the experience and welcome the chance to get some rest from my laptop.

There will be a school on quantum gravity this summer in Morelia, Mexico, from June 23rd to July the 3rd. Don Marolf, the chair of the event asked me to promote the event. The deadline for applications is January 31st (the end of this week).

There is also going to be a workshop on future directions in lattice gauge theory, this summer at CERN. This is of interest to me, but I don’t know if I will be able to make it or not.

Also, the deadline for the Aspen Center for Physics summer 2010 session is by the end of this week.

In the fall there will also be an interesting workshop on aspects of the AdS/CFT correspondence at the Galileo Galilei Institute for Theoretical Physics in Florence. Again, very interesting, but I don’t know if I will be able to make it.

I have just attended the XV European Workshop on String Theory. It took place in Zürich, Switzerland. Here is the link to the conference information and the talk slides. The conference featured a lot of young speakers who I had not met before. I found it very entertaining. Curiously enough, I really got to feel for the first time that different countries have their own way of doing physics. I think this reflects a bit on the attitudes of different cultures on what constitutes good taste. There is nothing wrong per se with any such preferences, it’s just an observation that I have heard many times before, but it had not really made itself so obvious to me as this time around. The menu of topics covered was rather formal and the hospitality of the event was incredible. I’m very grateful to Matthias and Matthias for providing such a welcoming environment. Here is a picture of Zürich (the best of the ones I took while wandering aimlessly through the streets of the city).


The weather was absolutely perfect and the town is truly a lovely place to loose oneself into.
