Abu Ja`far Mohammed ibn Musa al-Khowarzmi
This Persian mathematician discovered the algorithm
wich derives of the name of his deiscoverer. [aj] -
600 BCE
Plato
introduced the ideas or abstractions of mathematics.[aj] -
500 BCE
Aristotle
presesnted: deductive and systematized reasoning.[aj] -
500 BCE
zero
The Hindu numbering system invented zero. [a,j] -
350 BCE
Euclid
established the anxiomatic methood.[a.j] -
1 BCE
The Romans
invented the abacus. [a,j] -
1202
Leonardo Fibonacci
He travelled extensively through North Africa, where he learned the arabic numbering and positional use of zero, after this,Fibonacci wrote a book that served to introduce Arabic numerals into Europe.[aj] -
1545
Geronimo Cardano
This Italian mathematician, demonstrated that debts and similar phenomena could be treated with negative numbers. [a,j] -
1580
Francois Viéte
began to use letters to symbolize unknown values (variables) and thus laid the foundations of algebra.[a.j] -
John Napier
invented logarithms. [a,j] -
Edmund Gunter
He invented a precursor to the calculation rule.[a.j] -
Wilhem Schickard
Schickard designed and built what is considered the first digital calculator. Schickard's calculator allowed automatic additions and subtractions, and partially automated, multiplications and divisions. Unfortunately, Schickard and his entire family died during an epidemic, and hisinventionhad no diffusion. [a,j] -
Galileo
Galileo laid the foundations for mathematical formulation.[a.j] -
René Descartes
He discovered analytical geometry.[ja] -
Blaise Pascal
Although he is generally regarded as the inventor of the calculator, he manufactured his wits twenty years after Schickard and was less advanced. It was based on a toothed wheel system and given the technology of the time failed to manufacture any reliable models.[a.j] -
Gottfried Wilhelm Leibniz
He was, along with Isaac Newton, the co-discoverer of calculus.Based on Pascal's work he built a device, known as the Leibniz wheel. This device could automatically perform additions, subtractions, multiplications and divisions. Leibniz was also the first Western thinker to investigate binary arithmetic and laid the foundations for symbolic logic, based on symbols and variables abstracting the semantics of propositions. [a,j] -
Charles Babbag
He was one of the founding members of the Royal Astronomical Society of England. He proposed two computer machines moved by steam machines.[a.j] -
Pehr George Scheutz
Managed in to build a highly specialized "differential" machine. It operated using punched cards containing series of operations and data. [a,j] -
Boole
His most prominent contribution was a book "An Investigation into the Laws of Truth"[a.j] -
John V. Atanasoff
Physicist, and associate professor at Iowa State University, with the help of an undergraduate student named Clifford E. Berry. built the ABC (Atanasoff Berry Computer), it used binary arithmetic and was single-purpose. [a,j] -
John von Neumann
An outstanding mathematician, became interested in the design of computers. When he was twenty-three he was already a renowned mathematician throughout the world. He had carried out important studies in formal logic and collaborated to axiomatize mathematics. Von Neumann combined the systematization of logic and the possibility of performing calculations quickly and reliably. [a,j] -
Howard T. Aiken
Collaborated with a group of IBM engineers, designed and built an electromechanical machine (Mark 1) capable of multiplying two numbers in six seconds and dividing them by twelve.[a.j] -
John Mauchly
The designer of ENIAC, the first large-scale digital computer.[a.j] -
John Backus
He developed the first high-level language called FORTRAN (FORmula TRANslator). [a,j] -
Grace Hopper
She developed a high-level language (for computing) called COBOL (Common Business-Oriented Language).[a.j] -
J.C.R. Licklider
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. In October of that year, Lickider was the first director of ARPA. [a,j] -
Niklaus Wirth
He developed de high-level language PASCAL.[a.j] -
Vinton Cerf
He began the development of the protocol that would later be called TCP / IP, a protocol aimed at communicating some networks over others. [a,j] -
William Gibson
He was thw one who novelized the new world and coined the term "cyberspace". [a,j]
