message: I don't see explict mention of one of the most important scientific achievements to come out of CERN: the precision measurement of the Z lineshape.  There's an indirect mention: the 1989 publications on the number of light neutrino species based on the first few Z events collected in 1989.  However, there are two main reasons why that isn't quite the same.  First, orders of magnitude more data were collected (with much better precision) from 1990 to 1995; in fact, the 1989 data were not even used in the final lineshape measurement.  And second, the Z lineshape does more than give the number of light neutrinos: it constrains the Higgs boson mass, provides several precision measurments of the Standard Model (e.g., lepton universality, unitarity of the neutrino mixing matrix, etc.), and constrains parameters of Supersymmetry and other beyond-the-Standard-Model theories.   
So, I thought I'd add it.  However, it's hard to assign a date to the lineshape measurement.  The bulk of the data used for the measurement was collected from 1990 to 1995 when LEP ran at the Z pole, and several preliminary results were published in the mid-1990s. However, the LEP electroweak working group continuously refined the systematics and didn't publish their final result until 2005 (after incorporating data from SLAC).  So in the absence of any other ideas, I'll put down 1995-2005 as the date of the measurement.  But if anyone has other opinions, feel free to change it. Gdlong (talk) 17:53, 11 April 2023 (UTC)
thread_title:  Z Lineshape 

message: Here's an excerpt from another language:
In the aftermath of the Second World War, European research in physics was almost non-existent, whereas it had been at the height of its glory a few years earlier.  It was under these conditions that the Frenchman Louis de Broglie, Nobel Prize in Physics in 1929, launched the idea, at the European Conference on Culture held in Lausanne in 1949, to create a European scientific laboratory.
In 1952, with the support of UNESCO, which promotes the creation of regional scientific laboratories, eleven European governments decide to create a European Council for Nuclear Research (CERN).  It is during a meeting in Amsterdam that the site where the CERN facilities will be located is chosen: it will be in Switzerland, in the municipality of Meyrin, located against the Franco-Swiss border, near Geneva.

replies: text: It's strange. Contemporary video footage clearly shows a "Centre Européen pour la Recherche Nucléair" sign when the construction works began. Then, at the time of laying the foundation stone by Felix Bloch, it was called as European Institute for Nuclear Research.  — Preceding unsigned comment added by Yogurt (talk • contribs) 09:37, 29 September 2023 (UTC)
thread_title:  History, missing quite a lot 

message: The "Computer science" section says about the World Wide Web, "It became the dominate way through which most users interact with the Internet."  As far as I know, even "British English Oxford spelling" doesn't replace "dominant" (the adjective) with "dominate" (the verb).  This is admittedly a trivial error, but one that I've encountered often enough that it annoys me every time. 173.61.40.240 (talk) 22:08, 6 December 2023 (UTC)
