Famous computer science biography

Famous and great informatics, programmers, people who have made an invaluable contribution to the development of computer science Leonardo di Sero Pierro da Vinci on April 15 - May 2 Italian artist painter, sculptor, architect and scientist Anatom, natural scientist, writer, writer, musician, one of the largest representatives of art suggested a kind of modification of Abak at the end centuries.

Leonardo da Vinci created a sketch of a discharge summing device with ten -toothed rings. The drawings of this device were found among the two -volume meeting of Leonardo by mechanics, known as “Codex Madrid”. This device is something like a counting machine, which is based on the rods, on the one hand, the smaller on the other, all the rods of only 13 were to be located so that the smaller on one rod touches the larger on the other.

Ten revolutions of the first wheel were supposed to lead to the same complete circulation of the second, 10 to one full of the third, or on August of Ada King, a nee Bairon, Countess Lovelyis - a mathematician. It is known primarily by the creation of a description of the computer, the project of which was developed by Charles Babbiga. Compiled the world's first program for this machine.

The terms “cycle” and “work cell” introduced into use. Ada describes the algorithm for calculating Bernoulli numbers on an analytical machine. It was recognized that this is the first program specially implemented for reproduction on a computer. Nowadays, Hell Lovelyis is rightfully called the first programmer in the world, despite the fact that the Babbiga car was never constructed during the life of hell.

Muhammad Ben Musa al-Khorezm OK. It was called the "Kitab al-Jebr" "Kitab al-Jabr Wa L-Muqabala". This book gave the name to the science of Algebra. Another book of Al-Khrezmi played a very large role, in which he described in detail Indian arithmetic. Three hundred years later, this book was translated into Latin, and it became the first textbook of the Indian, that is, our modern arithmetic for all European cities.

Muhammad Ben Mus Al-Khorezm, we owe the appearance of the term "algorithm". The rules in the books of al-Khorezmiv in the Latin translation “Algoritmi de Numero Indorum” began with the words “algorism said”. In other Latin translations, the author was called "algorithmus." Over time, it was forgotten that Algorithmus Algorithmus is the author of the rules, and these rules began to be called algorithms.

For many centuries, algorithms have been developed to solve more and more problems of problems, but the very concept of the algorithm did not have an accurate mathematical definition. Currently, the concept of the algorithm is clarified. Konrad Tsuze - a German engineer, a computer -building pioneer, was born on June 22 in Berlin. His father, Emil Tsuze, was a postal official, earned a little, but together with his wife Maria Tsuze, and Sister Konrad - Liselotta, did everything that he could to support his son’s interest in constructing computing machines.

He was going to build a series of computers originally called Versuchsmodell experimental model. The first Versuchsmodell, V-1, built in the year, was completely mechanical, for 16 machine words and occupied an area of ​​4 square meters. The Versuchsmodell Tsuza series considered as a working tool for engineers and scientists who dealt with complex aerodynamic calculations. Tsuze wrote a small essay where he spoke about his creation and the possibilities of using it to solve such problems as sorting numbers and performing operations in binary arithmetic.

Having learned to play chess, Tsuze wrote several fragments of programs on Plankalkul, which allowed the computer to evaluate the chess position. Many ideas of Plankalkul have remained unknown to the whole generation of programmers. Only in the year the work of Tsuz was published entirely, and this publication forced experts to think about what influence could have had Plankalkul, if it was known earlier.

One of them says that any effectively axiomatized theory, in a rather rich language that is sufficient to determine natural numbers and operations of addition and multiplication, is incomplete or contradictory. Incompleteness means the presence of statements that cannot be proved or refuted based on the axiom of this theory. Contractiveness is the opportunity to prove any statement: both true and false.

Effective axiomatization is understood as an opportunity to algorithmically decide whether this statement is an axiom. An extremely important phenomenon of algorithmic insoluability is associated with Gedel's theorem of Gedel. It is based on the fact that there are classes of correctly posed mass problems that allow the use of algorithms, for which, nevertheless, the absence of any algorithms for their solution has been proved.

Theorems proven by Gödel have broad consequences for both mathematics and philosophy. Laid the foundations of theoretical computer science. Jeff Raskin English. Raskin left Apple in and founded the company Information Appliance, Inc. Information Appliance later supplied Swyft as a separate computer.In the year, the project was renamed Archy. The works were continued by his son, Azu Raskin, in Humanized, founded shortly after the death of Jeff Raskin to preserve his heritage.

Humanized released the ENSO program dedicated to Jeff's memory and based on his interface work. Steve Jobs is an American businessman, a talented leader, co -founder of Apple Corporation, her ideological inspirer, director and chairman of the board of directors. It happened at the end of the x. Jobs later saw the commercial potential of the graphic interface guided by the mouse, which led to the appearance of Apple Lisa computers and, a year later, Macintosh Mac.

In the year, Jobs left Apple and founded Next - a company that developed a computer platform for universities and businesses. In the year, he acquired a division of computer graphics of the film company Lucasfilm, turning it into a Pixar studio. He remained CEO Pixar and the main shareholder until the studio was acquired by The Walt Disney Company, which made Stephen Paul the largest private shareholder and member of the Disney Directors Board.

In the year, Apple bought Next. As part of the transaction, Steve Jobs received the post of Apple adviser. By the year, Jobs returned control of Apple, heading the corporation. Under the leadership of Steve Paul Jobs, the company was saved from bankruptcy and a year later she began to profit. Charles Babbage December 26 - October 18 English mathematician, inventor of the first analytical computing machine.

In the year he created a different car and was awarded the first gold medal of the astronomical society. But the small variable machine was experimental, had a small memory and could not be used for large calculations. In the year I thought about creating a programmable computer, which he called the analytical prototype of a modern computer. Unlike a diverse machine, the analytical machine made it possible to solve a wider series of problems.

It was this car that became the matter of his life and brought posthumous glory. He assumed that building a new machine would require less time and means than refinement of a different machine, since it was supposed to consist of simpler mechanical elements. Since the year, Babbage began to design an analytical machine. The architecture of a modern computer is largely similar to the architecture of the analytical machine.

In the analytical machine, Babbage provided the following parts: Store warehouse, factory or Mill mill, control element of Control and information input and output devices. Babbage provided the ability to enter instructions into the car using punch. However, this machine was not finished, since the low level of technology of that time was the main obstacle to its creation.

Charles Babbija is often called the “father of the computer” for the analytical machine he invented, although its prototype was created many years after his death.

Babbage left a huge mark in the history of the XIX century. And made a coup not only in mathematics and computing technology, but also in science as a whole. Gottfried Wilhelm Leibniz on June 21 - November 14, a German philosopher, logician, mathematician, mechanic, physicist, lawyer, historian, diplomat, inventor and linguist created a mathematical analysis - differential and integral calculus; created combinatorics as a science; Only in the whole history of mathematics he worked equally freely both with continuous and discrete; He laid the foundations of mathematical logicia described the binary number system with numbers 0 and 1, on which the modern computer equipment was founded in the year, after meeting with Christian Huygens, Leibniz created a mechanical calculator an arithmometer that performs addition, subtraction, multiplication and division of numbers, as well as the extraction of roots and erecting a degree.

The car was demonstrated at the French Academy of Sciences and the London Royal Society. For many years he devoted to energy, dealing with the problem of stability of energy systems. At the end of the 10ths, seeing the need for the national economy and the defense industry in computer technology, he switched to a new scientific field. Since the year, Lebedev worked in Moscow, where he headed the laboratory at the Institute of Exact Mechanics and Computer Technology of IMT and TT, and since the year he was the director of this institute.

Niclaus virtual German. Niklaus Wirth, kind. Leading developer of languages ​​Pascal, Module-2, Oberon. Its most famous development, of course, is the Pascal programming language, which had a huge impact on several generations of programmers and became the basis for creating a large number of programming languages. Another fundamental work, the participant of which was the WIRT - the development of structural programming technologies, which became in programming, of course, the strongest formalization of at least the 10th -10ths.

This technology has been developed, substantiated and implemented by only three outstanding people - Virta, Deikstroy and Hoar. Commentators have repeatedly noted that Virta’s ideas often ahead of the development of the computer industry for years, sometimes for decades.Bill Gates is an American entrepreneur and public figure, philanthropist, one of the creators together with Paul Allen and the former largest shareholder of Microsoft.

Until June, he was the head of the company, after leaving the post he remained in the position of its non -executive chairman of the board of directors. He is also the co -chair of the Bill and Melinda Hates, a member of the Board of Directors Berkshire Hathaway, gene. In the year, after developing the new Altair personal computer, Gates contacted the president of the MITS developer company, and said that he and his friend are working on the software of this computer.

The company was specially designed to develop programs for MITS in Igor Anatolyevich Danilov on April 22, Leningrad - a famous Russian programmer, author of the popular antivirus Dr. Web, Technical Director and Founder of Doctor Web. He graduated from the Kachinsky Higher Military School of Pilots, Volgograd. He was a military pilot. After studying at the Leningrad Institute of Aviation Instrumentation, he worked as an engineer for aviation defense projects at the Leninsky Central Department Store.

From a year, he has been developing in the field of antivirus protection. Igor Danilov wrote his first viral analyzer out of enthusiasm, wanting to save his research institute from viral threats. In m began the development of antivirus Dr. In M, he founded the company "Doctor Web". The company's staff is from above by offices in Moscow and St. Petersburg.
