8. The development of new materials (throughout the 1900's)
Much of the technology of
the 1900's resulted from the introduction of new materials. Aluminum
and alloy steels, for example, contributed to the evolution of aircraft
into a reliable and safe component of the world's transportation
network. These materials also played a key role in the development of
rocketry. Plastics
and other polymers came into widespread use. Today, manufacturers
use them to make the casings of telephones, televisions, radios, and
computer chips. In addition, plastics are used to produce film, pipes,
garden hoses, garbage bags, automobile parts, CD's,
computer keyboards, and thousands of other items.
