There once was a time when I was struggling with difficult theoretical problems, and I would wake up in the middle of the night with solutions, or at least with important insights. Once the morning arrived, I would recall getting the insights, but couldn't remember what they were. To fix the problem I put a notepad and pen beside my bed, and went to bed with the firm resolve to write down any ideas I got in the night. It worked: I woke up with yet another brilliant idea, and spent some time writing down all the details. In the morning, I found the sort of scrawl a two-year-old might have written. -- Peter Moylan, Newcastle, NSW, Australia. http://www.pmoylan.org For an e-mail address, see my web page.

However, since then, air-conditioners have become more common, and so there is no net saving of electricity at all. In fact, our power people say we use more electricity in summer than in winter and slightly more during our most recent experiment with daylight saving time. -- Rob Bannister
