Samuel Morse demonstrated the ability of a telegraph system to transmit information over wires. The information was sent as a series of electrical signals. Short signals are referred to as dits represented as dots.Morse code is a method of transmitting information as a series like, lights or clicks that can be directly understood by a skilled listener or observer without special equipment.The telegraph revolutionized long-distance communication. The electrical signals were transmitted over a wire laid between stationsIn addition to helping invent the telegraph, Samuel Morse developed a code (bearing his name) that assigned a set of dots and dashes to each letter of the English alphabet and allowed for the simple transmission of complex messages across telegraph lines.
The telegraph changed the method of communication during the 2nd revolution. It was invented by Claude Chappe in 1794. This system was visual and used semaphore, a flag-based alphabet, and depended on a line of sight for communication. The optical telegraph was replaced by the electric telegraph. It is a device used to transmit coded electrical pulses through a cable to a receiver, where the message was decoded messages. It couldn’t transmit voice or other data and used only the encoding pulses to content.
The word "telegraph" usually refers to the system of long-distance communication in which messages are transmitted via electrical signals on wires. Normally a person does not refer to the wireless telegraph and radiotelegraph, and are not part of the popular concept of the device.

In 1844, Morse sent his first telegraph message, from Washington, D.C., to Baltimore, Maryland; by 1866, a telegraph line had been laid across the Atlantic Ocean from the U.S. to Europe. Although the telegraph had fallen out of widespread use by the start of the 21st century, replaced by the telephone, fax machine and Internet, it laid the groundwork for the communications revolution that led to those later innovations.

The first airplane was created by the Wright brothers, Orville and Willbur and it was invented in 1903 in Britain and then in America.They were americans pioneers and inventors of aviation. They created their own milestone two years later when they built and flew the first fully practical airplane.
These two American brothers, converted the dreams into reality by building the first real flying machine called 'Airplane'. The Wright Brothers designed their first aircraft: a small, biplane glider flown as a kite to test their solution for controlling the craft by wing warping. Wing warping is a method of arching the wingtips slightly to control the aircraft's rolling motion and balance.

The search for alternative power sources started almost as soon as the Industrial Revolution began. However, it was a very long process and it was not until the middle of the 19th century that these alternatives began to be put into use. In some cases they started life as just interesting experiments, with seemingly no practical application. Only after a long period of time did they emerge as useful power.
In 1831, Faraday made the fundamental discovery that an electric current was induced in a coil of wire when a magnet, placed near the coil, was moved. By this discovery, he underlined the close relation between the sciences of electricity and magnetism. This relationship had first been demonstrated by Øersted (a company) eleven years ago, when they showed that an electric current produced a magnetic field. Faraday went on to show that the induced current could be produced in several different ways: for example, the coil could be moved while the magnet remained stationary, or a current could even be produced without any movement if an electro-magnet, which could be switched on and off, was used.
By 1832, the idea had been developed into a practical electrical generator, which was demonstrated in Paris during that same year. By mid 19th century, industrial uses were being found for electricity and, by the 1880s, electrical energy was being generated on a large scale. The two main areas being investigated at this time for the use of electricity were in lighting and as a driving force.
