When I was taking a walk this morning, I met a gentleman, whose age is probably nearly 70 or 80 years old, on a way back to the clock tower in Abinger Hammer from the North Downs. The begining was just a brief exchange of greetings, but gradually our conversation evolved into a comment about colourful British landscape in early autumn (meaning now), global warming, and finally superstring theory! Surprisingly, this old gentleman is thirsty for knowledge, particularly on science. It seems physics is his best interest. I have never met an ordinary people (I mean, non-scientists) who knows that the M-theory implies we are living in the D-brane floating in the 11-dimensional world! I respcet this kind of people, with full of curiosity and a strong will trying to improve themselves.
Surrounded by English myst in October, I guess we have talked more than 30 minutes on the village path, about the fate of the universe. Maybe, blackbirds and robins were singing in the fence of the cow fields, and the sounds were transmitted through the fog. The white sun was about to appear with lights to make the colour of the North Down Hill more vivid. This environment and nice, respectful people.... is the reasons why I sometimes like a life in Britain, doing physics.
