Meet the Inventor:

Guglieelmo Marconi was born on on April 25, 1874 in Bologna, Italy. He was the second son of Giuseppe Marconi, and Annie Jameson.
He received his education privately in Bologna, Florence and Leghorn. As a young man he was interested in physical and electrical science. He studied the works of Maxwell, Hertz, Righi, Lodge and others. He started laboratory experiments in his father's country estate at Pontecchio where he successfully sent wireless signals over a distance of one and a half miles in 1885. So he proved the radio was capable of communicating. Before 1899 he sent the first wireless signal across the English Channel. About two years later received a "S", telegraphed from England to Newfoundland. This was the first successful telegraph message by radio to cross the Atlantic in 1902.
Marconi was awarded honors by many countries. In 1909, Guglielmo Marconi and Karl Ferdinand Braun won the Nobel Prize in physics for his achievement in wireless telegraphy. In World War I he was put in charge of the Italian wireless service. He developed short-wave transmission as a way of secretly communicating.

.I htink that this website was good but not as good as the second website. It s purpose was to inform. The author was Mary Bellis. The copyright is 2010 so I think that the information was fairly recent. It did give you other cites that you could go to to get information so that is really good.This site was to find and verify which is what I think all of the cites our gruop used were for.

I think that this was a really good website. This was a really good website that was ment to inform. It did give you other links which is good. The author was a company so the information can be more accurate. Its copyright date was 1909 so it could be more accurate but the information being from a company makes it better. I think that this website was to find some facts.
http://www.ideafinder.com/history/inventors/marconi.htm This site was not very accurate cause it did not provide good enough information, such as it did not give the authors name. The site seems somewhat up to date being electronically published in 1997. The purpose of this website was to inform me on my inventor and it did a good job at that.I say that the site could have added more information. It did provide links with other websites which was helpful. I usd this site to find some additional information on my inventor. It mostly helped me find what i was looking for.I think that this website was to confirm and verify previous facts.

Invention:

We give credit to Guglielmo Marconi for the invention of the radio.
Guglielmo was an Italian inventor. In 1895 he sent and received his first radio signal in Italy. By 1899 he flashed the first wireless signal across the English Channel, two years later received the letter "S", telegraphed from England to Newfoundland. This was the first successful transatlantic radiotelegraph message in 1902.



In 1890 he became interested in wireless telegraphy. By 1895 he had developed apparatus, with which he succeeded in sending signals to a point kilometers away by means of an antenna.

After he patented his system in Great Britain, he formed Marconi's Wireless Telegraph in 1897. In 1899 he established communication across the English Channel between England and France. In 1901 he communicated signals across the Atlantic Ocean. His system was soon adopted by the British and Italian navies. By 1907 had been so much improved that transatlantic wireless telegraph service was established for the use of the public.

While Working on the Radio:

At first, the distances were short. The distance was the one hundred meters between his house and the end of the garden. It then became essential to show that, by using the broadcast was also expected between two points estranged by an obstacle. Scientists and other experts detained that electromagnetic influence could only be transmitted in a straight line and then only if there was nothing there, or in the way.

In particular, they thought that the main barrier was the curvature of the earth's exterior. Marconi was more involved in practice than theory, and so he located his transmitter near his home, the receiver three kilometers away, behind a hill. Overseeing it, there was the Marconi's servant, Mignani, whose only duty consisted in firing a rifle shot when the signal was acknowledged. When Mignani fired his firearm, for the first time in history the three dots of the letter "S" of the Morse alphabet had traveled through space.
The invention of the radio has impacted our lives mostly positvely. It has boosted our lives and our knowledge in technology and we can only move forward from the invention. Guglielmo Marconi was a very intelligent man and deserves full credit for all of his lifes accomplishments.

Web. 12 Oct. 2010. <http://www.italian-american.com/marconi.htm>. I find that this site was probably not the most accurate site to use. They did not provide an author for the selection. Also some of the grammar is off and some of the words are misspelled. The site is not very up to date since it was made in 1996. It did inform me more of the invention like intended. It also added links to other sites related to the topic. It helped me gather more information.

This particular site was overwhelming in information. All of this sites content seems very up-to-date being that it was only made two years ago. It did provide an author. It was also very easy to understand. It did not have links to other sites relating to the information. It helped me confirm everything i knew or needed to know about the radio. The purpose of it was to inform.

Additional Facts:


Some of Guglielmo Marconi's major events in life were he founded his own wireless telegraph company in 1897 in England.Marconi also served in World War 1, and directed Italy's radio service.He was also an Italian delegate to the 1919 Paris Peace Conference.Some of his lifetime accompishments are he go the Noble Prize for Physics, which he shared with a Geman physicist Ferdinand Braun. He was the first to discover that, because some radio waves travel by reflection from the upper regions of the atmosphere, transmission conditions are sometimes more favourable at night than during the day. Also, he was the first radio message from England to Australia in September 1918. Then he also was the president of the Royal Italian Academy in 1930. Something that makes him special is he was just full of ideas. He was always striving to make sure that his invention would work. He was so good at what he did that he was named the father of wireless/the radio. Some contributions he has made to society are that he sent the Morse Code messages through the air for short distances over land.
He later sent them across the Atlantic Ocean. By virtue of its Statute, Vatican Radio is the broadcasting station of the Holy See, legally based in the Vatican City State. It is a means of communication and evangelization created to serve the Pope's Ministry. It was established by him and inaugurated by Pius XI (Radio message Qui arcano Dei) on February 12th 1931. - helping the faithful to evaluate today's problems in the light of the teachings of the Church.Also at the age of only 21 he discovered how to telegraph through space. Some interesting facts about Guglielmo Marconi are that he was given a state funeral after his death in 1937. Also, he was an Irish-Italian inventor. Here is a little backround on our inventor Guglielmo Marconi.

I found that this was a really useful and really ful of facts.It also had a lot of extentions to other cites. The author Robert MacGregor Mitchell was really good at organizing the website. It doesn't tell you when the cite was last updated but seemed really up to date.The purpose of this website was definately ment to inform. I think that this website was to find information.

I think that this was a really organized website. It was separated by headlines, which is really helpful. For the information they gave I think that the information in the first website was a lot more helpful but this was still a good website to use.Another thing is that it was published by a company not a person so it may be more accurate. It's copyright date was 2003 so I guess its still pretty accurate. The purpose of this website is to inform and mabey have an advertisment for the company. I think that there were some extentions to ohter sites that could be very helpful. i think this was to confirm some facts.

I think that this website was probably the most useless out of the three I used. I think that the author of the website was Google but i'm not sure. It also doesn't tell me when the site was last updated but I think that it's up to date information.The purpose of this website is to inform. You can tell because its a timeline. It had a lot of extentions to other websites but I don' tknow if all of them were very accurate. I think that this website was to confirm and verify some previous facts.
