>… where W is word count, T is temperature and c is a constant the value of which I haven’t quite worked out yet. My basis for this theory? The fact that yesterday evening, still sweltering in the UK heatwave, I laboured for two hours over maybe five hundred words of manuscript that at best were distinctly average. This morning, I got up bright and early (well, early) and in one hour rewrote most of what I wrote last night and added another five hundred words for good measure. I reckon the temperature difference between the two sessions was a good twelve degrees. QED. I shall now submit my findings to the Nobel Foundation in the hope of receiving the recognition I deserve.
