Letter: Letter: Digital manouevres

Published 10 February 1990

From SIMON GOODMAN

When I got my first digital watch (it was also my last), I was struck
by the impossibility of the compass problem that Ariadne mentioned last
month (20 January). How was I to point the hour hand at the Sun, and, by
means of the method Ariadne described, find the direction of South? After
thinking for all of 3 milliseconds (or was it 5?) I twigged to the brilliant
thought experiment of imagining where the hour hand could possibly be (the
watch tells me – geddit?) and pointing that at the Sun instead.

I guess the old girl must be losing her thread.
