8.30 p.m. |HINT| What the Romans Did for Us: Ahead of Their Time
Adam Hart-Davis rediscovers the innovations and inventions the Romans brought to Britain. In Roman times, 176 days a year were public holidays. Adam looks at the entertainment that the Romans laid on to keep the citizens of the Empire content including the Hydraulis--the first ever keyboard instrument. He also tries out an automaton--a forerunner of today's robots. Adam discovers drawings for some farsighted ideas and recreates an inflatable portable bridge--similar to those used today by rescue services. But, as we see, the most lasting innovations were in the buildings--the Romans introduced concrete that has survived 2,000 years!
