In the heat of the afternoon I retire to our cool bedroom to read The New Scientist. Is it the intensity of the heat or my limited knowledge but incipient lethargy collapses my concentration and I am no nearer understanding how you measure a proton let alone discovering that its dimensions are considerably smaller than previously supposed? The femtometer, a very fine unit of measurement indeed, is used for the gauge. A new word for me, so I have learnt something. Chambers Dictionary defines the prefix femto as signifying a thousand million millionth. My Oxford Reference Dictionary doesn't mention it all. Perhaps it is too small for the editors to have noticed.
In the vegetable garden I cut some courgettes (zucchini), about the length of my little finger. Not to be measured in femtometers, but small enough to be a pleasure to toss in a frying pan with olive oil and a clove or two of garlic alongside the strident orange coloured flowers.
