Though architecture is surely an art, it is also a science and this program focuses on the scientific component. Skyscrapers have to stand up, not only to gravity but also to wind, precipitation, and sometimes earthquakes. The program also looks at another fascinating achievement of modern architectural science, the "intelligent home," many of whose features, including lighting or heating the house and even preparing morning coffee, can be fully programmed and executed automatically. Finally, the program tells us about concrete, a construction material that has become the symbol of modern architecture and is undergoing constant improvement. (23 minutes)
