This period is known as the classical period, and made an enormous contribution to the systematization of
reasoning. -
He was the discoverer of algorithms. The term "algorithm" derives from his name. He was Persian mathematician -
He was an Italian mathematician and he was the first to write about Arabic numerals in the West and he learned Arabic numbering and positional notation with zero. He wrote book that served to introduce Arabic numerals into Europe. -
He was an Italian mathematician was the one who demonstrated, in 1545, that debts and similar phenomena could be treated with negative numbers. -
He began to use letters to symbolize unknown values (variables) and thus laid the foundations of algebra. -
Was a Scottish mathematician and inventor that invented logarithms. He also made the use of the decimal point in arithmetic operations common. -
He laid the foundations for mathematical formulation. -
Edmund Gunter was an English clergyman and mathematician. He invented a precursor to the calculation rule. -
He designed and built what is considered the first digital calculator. Schickard's calculator allowed automatic additions and subtractions, and partially automated,
multiplications and divisions. His entire family died during an epidemic, and his invention had no diffusion -
He discovered analytical geometry. -
He was the inventor of the calculator,
manufactured his wits twenty years after Schickard and was less advanced. -
He was an excellent theoretical thinker and a prominent pragmatic man. He wrote: "It is a waste of time for qualified people to waste hours as slaves in the work of calculating, which could be delegated to
anyone else if machines could be used.". Some machines based on the same principles as Leibniz's,
have played a leading role in World War II. He was also the first Western thinker to investigate binary arithmetic and laid the foundations for symbolic
logic. -
He was one of the founding members of the Royal Astronomical Society of England. He proposed two computer machines moved by steam machines. -
He published "An Investigation into the Laws of Truth", In this work he established for the process of reasoning a symbolic representation. -
Swedish inventor, build a highly specialized "differential" machine -
Created a punch card technology that was used to control the census. This technology proved to be faster and allowed more questions to be asked in the census questionnaire. -
His main interest was to find an efficient method to solve systems of linear equations. -
He began working on the ENIAC project and took part in discussions about the design of a new machine, the EDVAC. -
He designed and built, in 1944, an electromechanical machine named Mark 1 capable of multiplying two numbers in six seconds and dividing them by twelve. -
The designer of ENIAC, the first large-scale digital computer.
-
Created FORTRAN. Winner of the Turing Award in 1977 for his work on high-level programming systems.
-
Created Common Business-Oriented Language. -
He wrote an essay on the concept of the Intergalactic Network, where the whole world is interconnected and can access programs and data from anywhere on the planet. -
Created PASCAL. In 1959 he obtained the title of Electronic Engineer at the Federal Polytechnic School of Zurich in Switzerland. -
Began the development of the protocol that would later be called TCP / IP. -
Novelized the new world and coined the term "cyberspace"
