Just got an email that I was selected to be part of the 2008 CERN-Fermilab HCPSS this summer.
From August 12th to 22nd I am going to be at Fermilab near Chicago!
Yeeeeehaa!

CERN Open Days 2008
This weekend was probably the last chance for the public to see the LHC and all its experiments.
I took part in quite a few visits (ATLAS, LHC, ALICE, CMS, LHCb, LHC control room, see pictures and my gallery) on Saturday (which was open only for CERN members and their families) and did about 7 tours (of one hour each) of the ATLAS detector on Sunday.
It has been a tremendous success and CERN managed to allow underground visits for a stunning number of 11.000 people on Saturday and 20.000 people on Sunday. The total number of visitor was estimated to be 23.000 on Saturday and 53.000 on Sunday.
ATLAS itself managed bring down about 2.200 visitors on Saturday and 3.500 visitors on Sunday. With tours starting roughly every 15 minutes we still had people waiting for about 4 hours to get to see the experiment.
I think, besides minor details, it has been a great success and I had a lot of fun showing people around and explaining them the LHC, ATLAS and many other things, even though I was completely wasted after about 9 hours of guiding (about 7 tours) and cleaning up and so forth.
I love that shit ;-)

Pi Day – 3/14

There’s a day for everything, even for Pi! An guess what, its today!
Simply because these crazy Americans write their date in a funny way (dd/mm).
Isn’t it great! Anway, the best Pi Day ever was actually March 14th 1592 (3.1415926535…).
But for some reason people didn’t appreciate it that much back than!?
It was March 14th 1988 they first started thinking about the relevance of this number and therefore founded the Pi Day.
Annual Meeting of the German Physics Society
Yesterday I came back from the Annual Spring Meeting of the German Physics Society in Freiburg. One week of more or less interesting talks, presentations and discussions on and about particle physics. Accompanied by some stuff about gravitation, astro-physics and other subjects.
Besides some good talks in the partcile physics sessions, it turned out that the other subjects were actually the best part.
You might ask, what other subjects means … good question!
First of all it means: speakers with private addresses not affiliated with any institute or university!
Hmm, you might ask why’s that … again good question!
Well, if you see the theories/idea/experiments, you know why!
My personal favourite, a guy exlaining everything utilising the E8 group! And when I say everything I mean it, or better he does! From the amino acids, on to the origin of mass, til the description of the fundamental constants.
Simply amazing …
Another guy was creating anti-gravitation using an improved version of his 12-vacuum-cleaner-engines-machine, and a third one was proving that the heat production in the earth is cause by the moon’s rotation around it, or something like that …
I actually made some movies, but they are unfortunately in German only.
W mass in ATLAS e-News
The ATLAS e-News recently published an article written by Troels (my former supervisor) about the forseen precision measurement of the W boson mass at ATLAS. Illustrating the development of the measured value and its uncertainty and giving a short summary of the results we published in our note (to be published soon, hopefully).
I am, amoung others, also mentioned in the end :-)
