‘Anomalies’ by Gregory Benford
This recalls Timescape in both subject (scientific investigation) and location (Cambridge). An amateur astronomer discovers an anomaly with the moon and promptly informs the Astronomer Royal. Since he is refered to as Martin we are to assume the story is set in the present day. However, it exists in some sort of neverneverland of class caricature. The original discoverer of the anomaly is a doughty working class furniture maker who actually folds his cap in his hands before saying:
Me, I’m just a five-inch ‘scope man. Don’t care about much beyond the priority, sir.
Later he goes with the Astronomer Royal to see a don who serves them tea and “small sandwiches with the crust cut off” before “deftly opening a bottle of sherry”. (Incidently this don is described as a “post-postmodern philosopher” which is what exactly?) And in addition to all this it is told in a grating documentary style.
