    X—rays were discovered in 1895 by a German Professor, Wilhelm Roentgen. People all over the world were amazed by his invention---- the X-ray machine. This invention was so important that Roentgen was awarded the first Nobel Prize for physics in 1901.

    The telephone was invented by Alexander Graham Bell, a doctor and a speech teacher for the deal. The first phone call was made by Bell in 1876. He had spilled(溅出) acid(酸) on his pants and wanted his assistant, Thomas Watson, to help him. The first words spoken on the telephone were “Mr Watson, come here! I need you!”

    Television was invented in 1926 by John Logie Baird, a Scottish inventor. Baird’s television certainly didn’t look like a television today! It was made of a box, knitting needles, a cake tin, a bicycle lamp, and a cardboard disc. Electronic televisions like the ones we have today were invented by Vladimir Zworykin in the 1920s in the United States.

    The first computer was built in 1946 by two American engineers, J.P.Eckert and John Mauchly. It was developed for the army, and it was so large that it took up an entire room! Later, in 1971, the “microchip” was invented, and small home computers were first produced for personal use. Today computers are involved(包含)in almost everything we do and are found almost everywhere we go.
