YOUR recent editorial on maths fun ("Anything that makes learning fun is welcome", The Herald, July 9) reminded me of our night school maths class at Coatbridge Tech some 60 years ago. Saint Pat's across the road was used as an overspill annex and a senior member of its maths department saw fit to come out at nights to take our class in what was always a challenging subject for us weary students.

I still clearly remember Mr Maccetti telling us of how Archimedes worked out some of his calculus theories while doodling in the foam in his bath. I never forgot this bit of his lecture and had the opportunity, in the course of time, to use it and pass it on to others as a valuable tool and fun too.
