From David Ayre
Thank you for the great article “Tools maketh the monkey” (11 October, p 42). It seems that Douglas Adams was, again, right in The Hitchhiker’s Guide to the Galaxy, where it is written: “a news report brought to you here on the Sub-Etha waveband, broadcasting around the galaxy, around the clock; we’ll be saying a big hello to all intelligent life forms everywhere, and to everyone else out there, the secret is to bang the rocks together”. It is particularly fitting that the article was published on page 42.
