INVENTIONS THAT CHANGED OUR LIFES

The telegraph machine and morse code

Samuel Morse and other innovators created the telegraph between 1830 – 1840 to transform long-haul communication. A wire connecting stations transmitted the electrical signals. Samuel Morse also invented a system called Morse code, which allows messages to be transmitted easily across telegraph wires. Based on the frequency of use, it allocated the English alphabet and numerals with a set of points (short marks) and dashes (long marks). According to some academics, the telegraph provided the basis for contemporary conveniences such as telephones and computer coding. Both systems are the same, however the Morse Code is easier and more accurate. The first Morse Code for instance uses speck and spatial examples to address a portion of the letters, while the International Morse utilizes spot and brief content blends for all letters. In addition, instead of utilizing the different lengths used in the primary Morse code, the International Morse Code utilizes consistent length screws.

 

Press Printing

The printer allowed information to go around the world before the Internet was able to disseminate information. Press, mechanism through which text and images are transmitted via ink to the paper or other medium. Although both moveable type and paper existed earlier in China, printing was automated in Europe for the first time.  German goldsmith Johannes Gutenberg is accredited for developing the printing press in1436, but the book printing process was not fully automatic. Printing of woodblocks in China goes back to the 9th century and a century earlier, Korean bookies printed moving metal types. Johannes Gutenberg’s machine, nonetheless, enhanced the all-around existing presses and acquainted them with the West. By 1500, Gutenberg presses were working all through Western Europe with a creation of 20 million materials, from singular pages, to flyers, and books. Of course, the creation of the press itself owes a lot to the mediaeval press, which was patterned on the ancient Mediterranean wine and olive press. A lengthy handle was applied to spin a large wooden screw, pressing down on the paper, which was placed on a wooden plate above the type. The wooden press reigned in the main for more than 300 years and on one side it was produced at a rate not much different from 250 sheets per hour.

Television

Television, is moving pictures and sounds from a source to a receiver are sent electronically. Television significantly affects society by growing the feelings of seeing and tuning in past the limits of actual distance. Conceived at the beginning of the 20th century as a viable means of education and interpersonal connection, it was transformed into a dynamic medium for broadcasting by the half-century, employing the broadcasting radio paradigm to provide people worldwide news and entertainment. In 1884 Paul Julius Gottlieb Nipkow invented an image rasterizer who was a 23-year-old German university student, which had a spinning disc with a spiral hollow pattern, such that a line of picture was scanned from each hole. Georges Rignoux and A. Fournier demonstrated for the first time in 1909 in Paris the instantaneous transmission of pictures. In 1911, Boris Rosing and his pupil, Vladimir Zworykin, built a method that sent primitive picture to a cathode tube or receiver with the use of a mechanical mirror drum scanner through drums. However, the technology was not sufficiently responsive to allow pictures to move.  Technical standards for contemporary television were developed for the first time in the middle of the 20th century, both monochrome (black and white) and color. Since then, improvements is  continuing and TV technology has altered significantly in the beginning of the 21st century.

Camera

In photography, a camera is a light-tight box with an aperture to allow light focused onto a sensitized film or plate for recording a picture of an object on a light-sensitive surface; it is essentially a light-tight box with an aperture to admit light focused onto a sensitized film or plate. This contemporary innovation experienced several phases of development — dark cameras, daguerreotypes, dry discs, calotypes, SLRs and DSLRs. In 1826, Joseph Nicéphore Niépce created the first permanent shot by using a sliding wooden cabinet camera built by Charles and Vincent Chevalier. Digital cameras have been developed to save images on memory cards instead of films with technical developments. Eugene F. Lally’s concept to snap photos of planets and stars began the history of the digital camera. The first Digital Camera was created in 1975 and afterwards invented by Kodak engineer Steven Sasson. It was constructed from bits of kits around the Kodak plant. The camera was approximately the size of a breadbox and a single photograph took 23 seconds. At least one built-in camera can be used to shoot video on any smartphone nowadays.
