Thursday, 29th. January 1976.

It was 0ºC in central London when I arrived – 10 minutes late – for my first geography lecture of the day, which was more of a practical: we were practising the use of stereoscopes to gain 3D images from aerial photographs, and to good effect. This is something that ‘spies’ do when looking at aerial and satellite images of, for example, evidence of potential weapons systems in hostile countries. This afternoon Climatology was on air pollution, and in particular a study underway on Kingsway and the Aldwych by the Joint School of Geography (King’s & LSE), measuring pollution at 3 metre intervals from the ground up as well as horizontally, using instruments attached to street lamps. It was interesting to see how concentrations dissipated quite rapidly away from the road both vertically and horizontally.

I spent 17p on lunch and managed to finish the NME crossword except for one clue – frustrating. This evening’s television included one of my favourite programmes at the time – Tomorrow’s World (BBC1). Why hasn’t something like that made a comeback? Tonight’s film was Only Two Can Play – Peter Sellers (1962).
