How odd, that University Challenge (BBC2) and Only Connect (BBC4), which follows straight on from it - Monday is quizzing night - should both have questions on the speed at which an object becomes hypersonic and on Britten's Young Person's Guide to the Orchestra tonight. Victoria Coren also threw in a reference to the origin of the benzine ring, which I know is a quizzing staple but one I've definitely heard used elsewhere within the past week.
Are the question setters moonlighting? Is it coincidence? Or am I just sensitized to such repetitions, seeing significance where none really lies (there is a "proper word" for this phenomenon, short of paranoid delusion, but I can't recall it).
It was news to me, by the way, that Britten's piece was a 1946 commission from the Ministry of Education. Yet another reason to admire the Attlee government!
