Electricity is the greatest gift of science to mankind. We have reached a point of our civilization when electricity is used for all purposes. Without it, our existence will be impossible. Electricity is a source of energy.
History[ edit ] Peter Mitterhofer's typewriter prototype Although many modern typewriters have one of several similar designs, their invention was incremental, developed by numerous inventors working independently or in competition with each other over a series of decades.
As with the automobiletelephoneand telegrapha number of people contributed insights and inventions that eventually resulted in ever more commercially successful instruments.
Historians have estimated that some form of typewriter was invented 52 times as thinkers tried to come up with a workable design.
In an Italian printmaker, Francesco Rampazetto, invented the scrittura tattile, a machine to impress letters in papers. The patent shows that this machine was actually created: He also invented carbon paper to provide the ink for his machine. Pratt 's "pterotype" InEssay about invention of electricity William Austin Burt patented a machine called the " Typographer " which, in common with many other early machines, is listed as the "first typewriter".
The Science Museum London describes it merely as "the first writing mechanism whose invention was documented," but even that claim may be excessive, since Turri's invention pre-dates it.
Burt and his promoter John D. Sheldon never found a buyer for the patent, so the invention was never commercially produced. Because the typographer used a dial, rather than keys, to select each character, it was called an "index typewriter" rather than a "keyboard typewriter.
By the midth century, the increasing pace of business communication had created a need for mechanization of the writing process. Stenographers and telegraphers could take down information at rates up to words per minute, whereas a writer with a pen was limited to a maximum of 30 words per minute the speed record.
It was an advanced machine that let the user see the writing as it was typed. In that same year the Brazilian emperor D. Pedro IIpresented a gold medal to Father Azevedo for this invention. Many Brazilian people as well as the Brazilian federal government recognize Fr.
Azevedo as the inventor of the typewriter, a claim that has been the subject of some controversy. Hansen Writing Ball[ edit ] Main article: Rasmus Malling-Hansen of Denmark invented the Hansen Writing Ballwhich went into commercial production in and was the first commercially sold typewriter.
It was a success in Europe and was reported as being used in offices in London as late as According to the book Hvem er skrivekuglens opfinder?
Who is the inventor of the Writing Ball? Malling-Hansen placed the letters on short pistons that went directly through the ball and down to the paper.
This, together with the placement of the letters so that the fastest writing fingers struck the most frequently used letters, made the Hansen Writing Ball the first typewriter to produce text substantially faster than a person could write by hand. The Hansen Writing Ball was produced with only upper-case characters.
The Writing Ball was used as a template for inventor Frank Haven Hall to create a derivative that would produce letter prints cheaper and faster. On the first model of the writing ball fromthe paper was attached to a cylinder inside a wooden box. Inthe cylinder was replaced by a carriage, moving beneath the writing head.
Then, inthe well-known "tall model" was patented, which was the first of the writing balls that worked without electricity.
Malling-Hansen attended the world exhibitions in Vienna in and Paris in and he received the first-prize for his invention at both exhibitions.
Soule in Milwaukee, Wisconsinalthough Sholes soon disowned the machine and refused to use, or even to recommend it. It looked "like something like a cross between a piano and a kitchen table.
Remington and Sons then famous as a manufacturer of sewing machines to commercialize the machine as the Sholes and Glidden Type-Writer. This was the origin of the term typewriter. Remington began production of its first typewriter on March 1,in Ilion, New York.
It had a QWERTY keyboard layout, which because of the machine's success, was slowly adopted by other typewriter manufacturers.Electricity is them most important invention of all time.
Greeks first found around BC that rubbing amber and fur together caused static electricity. For many years electricity was a mystery and many inventors experimented in order to understand more about how electricity work and how it could be used/5(4). The goal of Sudoku is to fill in a 9×9 grid with digits so that each column, row, and 3×3 section contain the numbers between 1 to 9.
At the beginning of the game, . The Online Writing Lab (OWL) at Purdue University houses writing resources and instructional material, and we provide these as a free service of the Writing Lab at Purdue. Like telephone, television is a wonderful gift of science after the invention of electricity.
Today, television is an important means of entertainment and education. With plays inspired by the sciences growing into a full genre, I thought readers would find it helpful to have this annotated list of such plays reviewed at CurtainUp.
All things considered, everything on this list offered something of interest though there were as many misses as hits. A typewriter is a mechanical or electromechanical machine for writing characters similar to those produced by printer's movable attheheels.comlly, a typewriter has an array of keys, and pressing one causes a different single character to be produced on the paper, by causing a ribbon with dried ink to be struck against the paper by a type element similar to the sorts used in movable type.
