  • Higgs boson and conformal symmetry

    Updated: 2012-08-30 18:38:42
    So far, I believed to be the only man on Earth to trust a complete absence of mass terms in the Standar Model (we call this conformal symmetry). I was wrong.  Krzysztof Meissner and Hermann Nicolai anticipated this idea. Indeed, in a model where mass is generally banned, there is no reason to believe that [...]

  • Why is CERN silent?

    Updated: 2012-08-28 05:42:00
    : Physics Without Ideology Bite by Bite The search for a theory of everything : satire about bad candidates and gentle fun about good candidates , such as the strand-spaghetti . model 28 August 2012 Why is CERN silent The LHC is producing collisions at a steady pace . The amount of 2012 data 12.7 inverse femtobarn is already the double of that used in the July 2012 announcements below 6 inverse femtobarns But there are no updates on the results . A few week ago I questioned why the ATLAS experiment changed its data retroactively and Matt Strassler answered that he hopes that this will happen regularly . I am simplifying the statements somewhat , of course Well , it is now time for CERN to change their old data again We all remember that the Higgs bump was huge in December 2011, and then

    Updated: 2012-08-26 08:58:33
    Neil Armstrong passed away yesterday (see here and here). He was the first man to put his feet on the Moon. He started all my dreams when I was just nine and that July’s night I was staring at his extraordinary enterprise together with Buzz Aldrin (see here) and Michael Collins on the Apollo 11. Now, I [...]

  • The Fabric of the Cosmos

    Updated: 2012-08-15 11:07:17
    TweetWhat is the fabric of the cosmos? Einstein told us that it is made up of a dynamic balance between the properties of space and time. For example he told us that space is a sort of multidimensional fabric, where the presence of mass causes the fabric of space to curve.  However he did not [...]
