Twentieth Century Inventions

1903-The first flight succeeded In 1900, Wilbur Wright said flight was possible for man. After much work, he and his brother Orville Wright made this dream come true.On December 17, 1903, the brothers made the first successful airplane flight on a windy beach at Kitty Hawk, North Carolina. The brothers' plane flew 120 feet. Although the flight lasted only 12 seconds, it moved the course of history in a new direction.

1935-Nylon was invented In 1928, a new chemical lab was opened to make a kind of man-made materials. Wallace Carothers took part in the team when he was 32 years old. In 1934, he made fibers(纤维), but the fibers were quite weak. He didn't give up. After many experiments, he produced the fibers "nylon". Carothers was very satisfied with his work. Nylon hit the markets in 1939, and quickly became a replacement of silk. But it was a pity that he didn't see the wide use of his invention. He died in April, 1937.

1968-The computer mouse was first shown in public.As a graduate student, Douglas Engelbart began to imagine ways in which all sorts of information could be on screens. In 1964, Douglas Engelbart made the first computer mouse. The computer mouse had a wooden shell with two metal wheels. In 1968, the first computer mouse appeared in public. It was named"mouse "because a tail came out at the end. In later years. the computer mouse became more and more important. Douglas Engelbart changed the way that computers worked. Now computer mice are becoming increasingly useful. And there are many different shapes of computer mice in the world.
