This is after an early(ish) start to the morning (7:30am) and with going late to bed last night (1:30am). A good lunch afterward helped restore things to a balance a bit, but I need to rest some more.

I’ve been modifying my lectures during the process of giving them, making adjustments for time and the kind of questions I get. This means that I end up kicking some parts to later lectures, and then trying to spend some of the afternoon writing new material, as well as on the train back to my hotel, and in the evenings.

Well, briefly in the evenings so far. That is because last night was set aside for a tour of some of the tapas you can find in the old part of Madrid. I had the presence of mind to go back to my hotel and get a short nap first, and then met my gracious […] Click to continue reading this post →

Recall that a few days back they hit the landmark of getting the machine to circulate beams again for the first time. (If you’ve forgotten what all of this is for, please search the blog for “LHC” and/or look in the related posts list at the bottom of this one.) Above right is a visual reconstruction of some of the collision data seen at the ALICE detector, and you can see more of this sort of data at CERN’s website (from where I got this graphic).
