Now, at that time in Melbourne there was a sixth form which was the top two years, it was called Pass Sixth and then Honours Sixth. And because of our financial situation I had to leave at the end of Pass Sixth, whereas those students who were thinking of going to university normally went on to do Honours Sixth, and I got a cadetship, as it was called, in the University of Melbourne. Now, that was a real stroke of luck, it meant that I could go to the university, attend the chemistry classes as what they call day release, but I was a technician in the Chemistry Department so I didn't have to walk far, and then in the evening I would study the other subjects one by one, in the evening. It was a long day.

[Q] Sounds it, Norman, I have to say.

I have to say because it was by now in the war and as part of the war effort the university donated some of its technicians to CSIR [The Council for Scientific and Industrial Research], the Government research organisation, now called CSIRO [The Commonwealth Scientific and Industrial Research Organisation], and... I was one of the youngsters who was transferred into this. So I joined a group which was studying the shock initiation of nitroglycerine. Nitroglycerine, as you well know, is a very temperamental liquid explosive, the slightest tap will set it off.
