Madam, - Dr William Reville's excellent article of October 2nd on the Large Hadron Collider experiment (curiously misspelled as "Collidor" in the headline and opening sentence) correctly points out that Ireland is not one of the 111 nations formally participating in the project.
While this is a sad state of affairs, it should be pointed out that many Irish physicists, both those working in Ireland and those of us overseas, have played and continue to play an active role in what is arguably the greatest scientific experiment of the century.
Here in Cambridge we actively collaborate with a group of physicists at University College Dublin on a project to help unravel the substructure of the proton using data from the LHC.
The contribution of Irish physicists to the LHC project deserves greater recognition. - Yours, etc,
