One of the most important inventions is the invention of the telephone. The idea behind the telephone is simple. a system which changes sound into a series of electrical impulses of differing frequencies (頻率), and then reverses this procedure to recreate the sound.

As early as 1831, Mickael Faraday proved that vibrations (震動) of metal could be changed into electrical impulses. This was the basic principle of the telephone, but no one made us of such technology until 1861, when German inventor, Johann Reis, successfully built some equipment that changed sound to electricity and back again. The equipment had built some equipment that changed sound to electricity and back again. The equipment had many flaws, unable to transmit many frequencies and therefore was never fully developed.

Two men in the United States Elisa Gray and Alexander Graham Bell (a Scottish inventor), both worked hard to create what would be known as the telephone almost at the same time, and amazingly both filed for a patent within hours of one another, Bell beating his rival by merely two hours on February 14 th, 1876.

The first comprehensible telephone conversation was said to have taken place between Bell and his assistant, who was sitting in another room. Bell said, “Come here, Watson, I want you”, which Watson successful heard via the receiver and the invention of the telephone was complete. The Bell Telephone Company (AT&T) was soon established and grew to be the largest telephone company in existence.

The following year, in 1877, the first telephone system was put in place in Hartford, Connecticut, while the first exchange linking two cities was established between Boston and New York in 1883. London hosted the first exchange put into practice outside the US in 1879.

Louis Armstrong had two famous nicknames(綽號). Some people called him Bagamo. They said his mouth looked like a large bag. Musicians often called him Pops, as a sign of respect for his influence(影響)on the world of music.

Born in 1901 in New Orleans, he grew up poor, but lived among great musicians. Jazz was invented in the city a few years before his birth. Armstrong often said, “Jazz and I grew up together. ”

Armstrong showed a great talent for music when he was taught to play the cornet(短號)at a boy’s home. In his late teens, Armstrong began to live the life of a musician. He played in parades, clubs, and on the steamboats that travelled on the Mississippi River. At that time, New Orleans was famous for the new music of jazz and was home to many great musicians. Armstrong learned from the older musicians and soon became respected as their equal.

In 1922 he went to Chicago. There, the tale of Louis Armstrong begins. From then until the end of his life, Armstrong was celebrated and loved wherever he went. Armstrong had no equal when it came to playing the American popular song.

His cornet playing had a deep humanity(仁愛)and warmth that caused many listeners to say, “Listening to Pops just makes you feel good all over. ”He was the father of the jazz style and also one of the best-known and most-admired people in the world. His death, on July 6, 1971, was headline news around the world.
