The impact

Before the invention of the radio, the communication back then wasn't that effective, then it is now . For example; people finding out what the weather will be like the day after, or if there are any emergency/news reports, and also entertainment. Inventing the radio made a big difference. We can now use them to signal out things or to talk through them, like Walkie-Talkies.

Guglielmo Marconi Dream goal

Gulglielmo Marconi began to experiment with these devices in the attic of his parent’s home. Guglielmo's goal was to use radio telegraphy and to transmit the waves as sort of a radio telegraph. The wireless telegraphy was something that he was aiming to produce. The first devices consisted of an oscillatior, capacitor placed above the ground,a receiver, telegraph key, and telegraph register. Guglielmo began the experiments indoors, and then later transferred them outside.

Invention of the Radio

The Future

Guglielmo developed an early interest in science and electricity. He began noticing the connection between electromagnetic waves and energy waves also known as radio waves. Guglielmo began an interest in these waves after the death of Heinich Hertz, one of the early pioneers in studying the waves. Marconi began to study these waves in depth in 1894.

Guglielmo Marconi successfully sent the first radio message across the Atlantic Ocean in December 1901 from England to Newfoundland. Marconi's radio did not receive voice or music, but did receive buzzing sounds created by a spark gap transmitter sending a signal using Morse code.

Radios are being combined with computers to connect the computer to the Internet. Eventually radios will convert from analog to digital broadcasting. Analog signals are subject to fade and interference, digital signals are not. They can produce high quality sound like that found on a CD.

Italian officials did not seem to be interested in Marconi's new device. It was not until Marconi demonstrated his wireless telegraph to William Preece which was an electrical engineer in London. Marconi traveled to London and began to impress the local engineer, Preece. Wireless messages developed enough to show to the public that they were quite impressed by the messages and the transmissions.

Guglielmo Marconi

Guglielmo Marcni was born in Bologna, Italy, in 1874. He was a Nobel Prize-winning physicist and inventor credited with the groundbreaking work for all future radio technology. Through his experiments in wireless telegraphy, Gugulilmo had developed the first effective system of radio communication. In 1899, the Marconi Telegraph Company was founded. In 1901, he successfully sent wireless signals across the Atlantic Ocean, disproving the dominant belief of the Earth's curvature affecting transmission. Guglielmo shared with Karl Braun, the 1909 Nobel Prize in Physics. He died in Rome in 1937.

Invention of the Telephone

Alexander Graham Bell

While he was moving jobs and locations around the UK and North America, Bell had developed a machine that could reproduce human speech.

Speech had become his life: his mother had gone deaf, and Bell’s father had developed a method of teaching deaf people to speak, which Bell taught. His research into mechanizing human speech had become a relentless obsession: in the UK it had driven him almost to collapse.

The very first telephone was invented in 1876

The Impact on Society

Before the invention of the telephone, the way people communicated was not very effective because it was a long process to send and receive mail back. The impact on society back then, was a major breakthrough and the telephones made a huge difference. Life now is much easier for people, because we can communicate by using the telephone, which makes our lives much more sophisticated.

Alexander Graham Bell was born on March 3, 1847, in Edinburgh, Scotland. He was a Scottish-born American scientist and inventor, most famous for his pioneering work on the development of the telephone. From his early life, Alexander had joined his father in his work with the deaf and soon assumed full charge of his father’s London operations. On one of his trips to America, Alexander’s father discovered its healthier environment and decided to move the family there. In July, 1870, the family settled in Brantford, Ontario, Canada. There, Alexander set up a workshop to continue his study of the human voice.

Passion for Shaping the Future

Alexander's Dream Goal Reached to a Success

In 1880, Bell was awarded the French Volta Prize for his invention and with the money, where he continued experiments in communication, in medical research, and in techniques for teaching speech to the deaf. In 1885 he reached land in Nova Scotia and established a summer home there where he continued experiments, particularly in the study of flying aircraft. In 1888, Bell was one of the founding members of the National Geographic Society, and served as its president from 1896 to 1904. Alexander died on August 2 ,1922 at his home in Nova Scotia.

Bell had long been fascinated by the idea of transmitting speech, and by 1875 had come up with a simple receiver that could turn electricity into sound. Others were working along the same lines, including an Italian-American Antonio Meucci, and debate continues as to who should be credited with inventing the telephone. However, Bell was granted a patent for the telephone on March 7, 1876 and it developed quickly. Within a year the first telephone exchange was built in Connecticut and the Bell Telephone Company was created in 1877. This was a huge success, and quickly made him a famous, wealthy man.
