Transcript of Computer History

By: Dixit Sandhu and Sahil Minhas History of Computers 50,000 B.C. -1000 A.D. Back in the BC and A.D. times there was no technology built. Actually, back then Benjamin Franklin did not yet discover electricity. Now that I think about it, he was not even born then. Well back on task, did you know the pioneers had used many natural things like rocks and bones to calculate math. Well any ways interesting fact, in 2600 B.C. Chinese invented an object to calculate math. That object’s name was an abacus. Abacus were also called abaci for plural or abacuses, it is now called a counting frame. Abaci were constructed with beans, stones and tablets of wood, stone, and metal. Now days they make a bamboo frame and beads sliding on wire. They had beans or stones moved in grooves in sand or on tablets of wood, stone, or metal to make them. After this invention, Chinese then started decimals and that was all for the BC and AD. 1400 Nothing happened much on the 1400s. Johannes Gutenberg had completed his development on the first printing press. While that was happening Leonardo Da Vinci had thought about inventing the 13, digit cog-wheeled adder used to fix decimal notation (10 digits). 1500 The 1500 were big. Leonardo created the first mechanical calculator and Peter Henlien had created the first watch. You might not think that the inventing a watch is that big but back then it was huge deal. It is like when the iPhone 5 came out. It was a huge deal to everyone was fascinated in technology. 1600 Did you know William Gilbert had created the term electricity from the Greek word elecktra, probably not. You might be surprised but in the 1612, the word “computer” was originally to describe a person who performed calculations or computations. Computer had meant the same thing until the end of the 1900s. Now dictionary.com defines the word “an electronic device designed to accept data, perform prescribed mathematical and logical operations at high speed, and display the results of these operations”. John Napier also created a system called "Napiers Bones," Napiers bones was made from horn, bone or ivory. These devices can multiple by adding numbers and divide by subtracting. Also in the 1600s, the German Wilhelm Schickard invented the first workable mechanical calculator. Wilhelm Schickard based the machine on the idea of Napier’s bones. That is a perfect example of how one invention leads to another. Gottfried Leibniz made our life easier by making the step reckoner, it was a machine that can multiply, divide, and evaluate square roots. It is also a calculator now days. 1700 On June 1752, Benjamin Franklin discovered electricity after his kite was electrocuted. Claude Chappe also invented the first non-electric telegraph. It was not that much as the other millenniums. 1800 1800 was a big millennium for the human race. Frances Joseph-Marie Jacquard invented the fully automated loom that is programmed by punched cards. Charles Xavier Thomas de Colmar had created the first successful calculating machine called the arithmetic". A man in Princeton invented the first working telegraph. Semen Korsakov uses punch cards just like Frances Joseph-Marie Jacquard to store and search for information. Once again a perfect example of an invention leading to another invention. I do not know what the Morse code is but I do know Samuel Morse invented it. That amazing code used different numbers to represent the letters of the English alphabet and then it used digits. March 25, 1857 was when Frenchman Édouard-Léon Scott de Martinville had invented the phonograph. It is able to transcribing sound to a medium. The telephone is very old as it was invented in 1876 and was said to be invented by Scottish-Canadian-American, Alexander Graham Bell. Emile Berliner invented something close to the telephone she invented the first microphone. Friedrich Reintzer had discovered liquid crystals. In addition, a German created the Cathode-Ray Oscilloscope, that German was the scientist Karl Ferdinand Braun. Thankfully, Wilhelm Röntgen had discovered the amazing X-rays on November 8, 1895. On a completely new subject, John Loud created the ballpoint pen on October 30, 1888. The last invention in the 1800s was the remote control invented by Nikola Tesla. 1900 I do not know how Paul Eisler invents the printed circuit board while working on the radio but somehow he did. Lowa State Colleges John Vincent Atanasoff and Clifford Berry had tried to invent their very first atanasoft berry computer. Chester Carlson invented the Xerox machine on October 22, 1938 after he produced the first electro photographic image. The Z3 was a fully program-operational calculating machine invented by Konrad Zuse. Enrico Fermi designs and creates the world's first Nuclear Reactor December 2, 1942.The world’s first nuclear reactor was designed and built by Enrico Fermi on December 2, 1942. The Colossus is the name of the first eclectic programmable computer invented by Tommy Flowers and the computer was released to the public to see on December 1943. What I cannot believe is that Motorola’s Dan Noble designed a walkie-talkie that weighed 35 pounds and that was the backpack version. It might be useful to know that that Luna 2 was the first human made object to land on the moon. I do not know if this is important but it was cool as physicist Theodore Maiman created the first laser in May 16, 1960. 2000 I just want to tell you how much I think 2000 has developed because In 2006 the PS3 was realised and now it is so popular in Canada almost everyone has it. My point is that 2000 has come so far with technology compared to the 1900s. Like look in 1965, it was black and white now we have things like HD and 3D, which would have been impossible in the 1900s. Most people think that Bill Gates dropped out of high school but he dropped out of Harvard to create Microsoft with his partner Allen. What I am sure that will shock you is that Wikipedia was created on January 15, 2001 so that means in 11 years a Wikipedia became the most popular web site on the planet. Now, unfortunately my awesome prezi is done. Hope you learned a lot of information. If you haven't then you could go to the site that I used for all the amazing information.The site is http://www.computerhope.com/history/ . http://www.youtube.com/watch?v=3gjDfc2AF3w By: Dixit Sandhu and Sahil Minhas These are some very importnt invetions.
Year: 1440
Invention: The printing press
Creator(s): Johannes Gutenberg
Significance: It is the reason we do not have to tire out our hands. It also makes our work more organized and neater looking.

Year: 1500
Invention: The mechanical calculator
Creator(s): Leonardo Da Vinci
Significance: This amazing invention helped all humans with mathematics, as not everybody is good at math.

Year: 1502
Invention: The first watch
Creator(s): Peter Henlein
Significance: The first watch had made humans not get late for stuff and helps us tell the time.

Year: 1939
Invention: The Complex Number Calculator capable of adding, subtracting, multiplying and dividing complex numbers.
Creator(s): George Stibitz
Significance: This calculator has more mathematical terms than the older calculators do which is even better.

Year: 1940
Invention: The first handheld two-way radio
Creator(s): Motorola
Significance: This is a great way for pilots and the army to communicate with other people. For example if a plane is going down then the pilot can call for help.
