Dear Rebecca Thank you for your letter. I seem to recall that it was my turn to write to you, but life had other ideas so Iā€™m glad you have kick-started our correspondence again. It sounds like you and Jim have been very busy -- exciting stuff. As for downsizing, everyone seems to be at it. My best friend and his wife have moved from the detached house theyā€™ve lived in for 41 years to a two bedroom apartment. He said that getting rid of hundreds of books was the most painful part.

Greetings! Here in London the mood is one of joyous celebration. People are dancing in the street, and giving hugs to random strangers. The unaccustomed heat (68 F today and that was cool by recent standards) has not been enough to prevent the merriment.

When I taught Economics I was always on the look-out for games and simulations that would help me get across certain difficult economic concepts. The ones I employed were Stockpiler and Running The Economy, which were, of course, intended to be used for such a purpose. But I also used Sim City and even Monopoly. This book looks at the maths concepts — and, to some extent, the physics concepts — hidden in popular video games.
