Explanation:
The Thames Barrier is a major part of the flood defenses scheme to protect London against rising water levels. The defenses also included raised embankments and in furthermore, flood gates at strategic points, including the Barking Barrier. The unique structure that is the Barrier spans the 520-meter wide Woolwich reach and consists of 10 separate movable gates, each pivoting and supported by concrete structures which house the operating machinery.
When raised, the four main gates each stand as high as a five-story building and as wide as the opening of Tower Bridge. Each measures 3700 tonnes. During the first twelve years of operation, the Barriers has been closed twenty times to protect London.
View the Barrier from the comfortable cafeteria. Picnic on the riverside. Picnic on the riverside embankment. Enjoy the beautiful view from the riverside walk. Visit the shop which stocks a large selection of souvenirs, books, and Barrier information.
There is a children's play area suitable for 4- to 12- year olds, located adjacent to the riverside walk. A visit to the spectacular Thames Barrier is a memorable experience.

So, the author's intent was to show that the early inventions fed new discoveries.
