Teasing equations on public transport
There was a man on the bus this evening who was furiously scribbling little mathematical notations on a grubby piece of paper. I was so curious to find out what he was doing! He was really going for it — several lines of closely-written squiggles. The only things I could make out properly were the long division lines separating numerator from denominator, and some Σs.
Was it maths? Physics? Engineering? I want to know! :-) It makes such a change from people reading Jackie Collins or talking loudly on their phones.
I got a phone call this afternoon from my aunt and uncle asking if my parents were okay in China. They are fine, though there might be difficulty getting out of the country now? I’m not sure, maybe there is not much disruption. It’s a very large place, after all.
