From Michael Berkson
The Large Hadron Collider is a wonderful achievement, but I am not convinced by Anil Ananthaswamy describing it as “the largest machine in the world” (30 August, p 31). I was told otherwise, ironically by a physicist at CERN, while I was employed by a telecoms company: this honour belongs instead to the worldwide telecommunications network.
From Mark Burrard
Given the amount of energy circulating the LHC and the much-debated possibility of it making Earth-consuming black holes, did anyone else find the small wall-mounted fire-extinguisher in the photo of the inside of the LHC tunnel a little bit incongruous?
