Experiments on communication with electricity, initially unsuccessful, started in about 1726. Scientists including Laplace, Ampère, and Gauss were involved.

An early experiment in electrical telegraphy was an 'electrochemical' telegraph created by the German physician, anatomist and inventor Samuel Thomas von Sömmerring in 1809, based on an earlier, less robust design of 1804 by Spanish polymath and scientist Francisco Salva Campillo.[8]Both their designs employed multiple wires (up to 35) in order to visually represent almost all Latin letters and numerals. Thus, messages could be conveyed electrically up to a few kilometers (in von Sömmerring's design), with each of the telegraph receiver's wires immersed in a separate glass tube of acid. An electric current was sequentially applied by the sender through the various wires representing each digit of a message; at the recipient's end the currents electrolysed the acid in the tubes in sequence, releasing streams of hydrogen bubbles next to each associated letter or numeral. The telegraph receiver's operator would visually observe the bubbles and could then record the transmitted message, albeit at a very low baud rate.[8] The principal disadvantage to the system was its prohibitive cost, due to having to manufacture and string-up the multiple wire circuits it employed, as opposed to the single wire (with ground return) used by later telegraphs.

The first working telegraph was built by Francis Ronalds in 1816 and used static electricity.[9]

Charles Wheatstone and William Fothergill Cooke patented a five-needle, six-wire system, which entered commercial use in 1838.[10] It used the deflection of needles to represent messages and started operating over twenty-one kilometres (thirteen miles) of the Great Western Railway on 9 April 1839. Both Wheatstone and Cooke viewed their device as "an improvement to the [existing] electromagnetic telegraph" not as a new device.

On the other side of the Atlantic Ocean, Samuel Morse developed a version of the electrical telegraph which he demonstrated on 2 September 1837. Alfred Vail saw this demonstration and joined Morse to develop the register—a telegraph terminal that integrated a logging device for recording messages to paper tape. This was demonstrated successfully over three miles (five kilometres) on 6 January 1838 and eventually over forty miles (sixty-four kilometres) between Washington, D.C. and Baltimore on 24 May 1844. The patented invention proved lucrative and by 1851 telegraph lines in the United States spanned over 20,000 miles (32,000 kilometres).[11] Morse's most important technical contribution to this telegraph was the simple and highly efficient Morse Code, co-developed with Vail, which was an important advance over Wheatstone's more complicated and expensive system, and required just two wires. The communications efficiency of the Morse Code preceded that of the Huffman code in digital communications by over 100 years, but Morse and Vail developed the code purely empirically, with shorter codes for more frequent letters.

The submarine cable across the English Channel, wire coated in gutta percha, was laid in 1851.[12] Transatlantic cables installed in 1857 and 1858 only operated for a few days or weeks (carried messages of greeting back and forth between James Buchanan and Queen Victoria) before they failed.[13] The project to lay a replacement line was delayed for five years by the American Civil War. The first successful transatlantic telegraph cable was completed on 27 July 1866, allowing transatlantic telecommunication for the first time.

Explanation:

Humans have a desire for better conditions and improvement since their first step on the planet, specially in communication. Language, distance weather conditions and others have always been a problem oh humans communication effectivelly, because of these mentioned points.

In order to solve all these communication problems gifted mem worked hard and devoted their lives to make other peoples lives better, it started with de creation of a communication code by Morse, the code, baptized with his name, was the precursor of many other modern equipment we have nowadays.

Not happy with this and looking for more modernity and evolution on communicating  another man started thinkind ahead and had the great idea to develop Morse´s idea on something better for all, and then the telegraph was made shortening distances and multiplying  the speed information was shared around the globe.

It was brilliante we must confess but none of the already mentioned were good enough to satisfy men´s needs, because of ths Graham Bell sat at a working desk and just rested after criating a machine that could permit communication by long distance not using signal but real voice.

When everyone thought it was enough or the top of invention new inventors bring everyday new inventins like cell phones and communication with videos, voice messages and app to facilitate life and communication.

the french revolution main idea was to give power to the people. the revolution was influenced by the enlightenment ideas, reasoning and skepticism pushed people to revolt against standards and norms in french society.

the problem was that the revolution caused political turmoil, and napoleon saw this as an opportunity and launched a coup d’état in november 1799. he became the first consul of france and later named french emperor.

some people see napoleon as a hero of the revolution and others see him as a traitor.

people see him as a traitor because he noticed the political turmoil and used this moment to rise to power. others see him as a hero of the revolution because he had some political and military achievements - in which he was committed to promoting the achievements of the french revolution - he had extensive public constructions, made a civil reform.

in a bigger picture, napoleon had some huge achievements in france which made him very important, but the fact that he seized power to himself makes him an undeniable traitor to the revolution since the main idea of it was to remove people from power and give power to the people.
