Top Five Best Inventions of The 20th Century

Have you ever wondered how something was invented? Have you ever wondered why they were invented? Well, I have and this is the result of that wondering.

During the twentieth century, inventions were needed to keep up with the times and be the best country we can be. Most of these inventions were used to keep up with the war, such as the radio and the airplane.

Other inventions, such as the car and television, were necessary to keep up with the automotive and technological world. Without all of these wonderful inventions, where we be today? Well, for starters, there would be no space travel, or for that matter, no travel at all.

The Radio:

Guliemo Marconi first created the radio. He invented it for navigational purposes. Marconi tried to mass-produce his idea but no bankers would lend him money because they thought there would be no money in it. After searching high and low for investors Marconi gave up. Later on in his life the U.S. government bought out his idea for navel and army uses. The government realized that they can do a lot more with it than use it as a navigational tool: They figured out that they can send voices and sounds through it and used it as a two-way communication device, then later found out that it can be used as more than a two-way. As this device was progressing, it became TV station waves (Later stated). The radio played a big part in world war I and II, not only on the battle field but on the home-front as well: People bought radios to use a listening devices to hear the news and there favorite broadcasting programs such as The Shadow, War of the Worlds, Suspense and Amos& Andy.

The Television:

The television was not ...

...act in 3/10 of a second. This computer was made out of tubes, switches, and relays and had over 750,000 of them. This computer was not the biggest made but for its work it was the largest and heaviest. The Mark one weighed over 5 tons and it was 50 feet long by 8 feet high. "Sounds like a room full of ladies knitting," said Howard. Aiken thought that the idea of a computing device "computer" would not become useful to every day people, just experts and scientists. If only he could see us now.
