Mid afternoon, I start my second U3AC course (University of the Third Age in Cambridge) in Cambridge this academic year. It is called "Ascent of Man" following the work of Jacob Bronowski who did a TV series some years ago. I recently got a second hand copy of the hardback book which accompanied the series. It was much cheaper than a new paperback copy.
The University of the Third Age has a huge range of courses in Cambridge. We are very lucky.
UPDATE 1745z: The course was very disappointing. Also we almost immediately divided into 4 groups of 3 to discuss questions and formulate answers. This is a format I just detest and with my poor voice I find discussing topics very hard. The lecturer was not very good as well. I may change courses. Already I have contacted the U3AC office to check availability on another course.
