ABSTRACT
A young research chemist, working on a military device during the War, was washing out a small clear plastic ampoule containing iodine. As he put the ampoule under the tap and the brown solution spilled over into the sink, there flashed into his mind a memory from his childhood in India, in which, at the age of seven, he and his father and mother had driven away for the day and had picnicked by a waterfall.
