Very informative, cross and inter-disciplinary course. Lot of effort is put into formulating and developing the course. Thanks for all the people who have contributed to run the course successfully.

I see the world differently now. Lots of interesting and important information that I either never knew or long-ago forgot. I bought the Maps of Time book for reference so I won't forget it again!
