Make-up of a CERN Collaboration

Screen shot 2010-02-11 at 3.10.40 PM

Grad students working for the CMS detector.

The experiments at CERN are, in total, a collaboration of several thousands of physicists, scientists, engineers, and students. Here I show the make-up of just graduate students from just one of the experiments at CERN, the CMS detector.

People come from all over the world to contribute to these projects. It’s fantastic that so many countries and cultures are represented, and work with each other on common goals such as: recreating the big bang in the lab, studying these mini big-bangs to understand out the laws of nature that govern our universe, and then sharing these discoveries with people all over the world.

These are lofty goals, but you can be sure that whatever discoveries are made, with all the languages spoken at CERN, the knowledge will spread far.

    To make it even more fantastic: There are people whose nationality is different from the nationality of the institution they are affiliated with. The CMS database does not record the nationality of individual person, but the CERN database does.

    Here is a picture showing how many people comes from countries/nations which have institutions affiliated with CERN.


    And here is a picture showing the nationalities of people at CERN .. irrespective whether their countries of nationality have institutions affiliated with CERN or not.


    The second picture shows that there more countries represented at CERN than just represented by the countries of the academic/research institutions.

    Do you have a similar pie-chart for the other experimental collaborations like ATLAS and LHCb?

  • @ac
    Unfortunately, I don’t happen to have plots for other experimental collaborations. You’d have to ask someone on those experiments.
