This Persian mathematician discovered the algorithm
wich derives of the name of his deiscoverer. [aj] -
introduced the ideas or abstractions of mathematics.[aj] -
presesnted: deductive and systematized reasoning.[aj] -
The Hindu numbering system invented zero. [a,j] -
established the anxiomatic methood.[a.j] -
invented the abacus. [a,j] -
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] -
This Italian mathematician, demonstrated that debts and similar phenomena could be treated with negative numbers. [a,j] -
began to use letters to symbolize unknown values (variables) and thus laid the foundations of algebra.[a.j] -
invented logarithms. [a,j] -
He invented a precursor to the calculation rule.[a.j] -
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 laid the foundations for mathematical formulation.[a.j] -
He discovered analytical geometry.[ja] -
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] -
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] -
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] -
Managed in to build a highly specialized "differential" machine. It operated using punched cards containing series of operations and data. [a,j] -
His most prominent contribution was a book "An Investigation into the Laws of Truth"[a.j] -
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] -
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] -
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] -
The designer of ENIAC, the first large-scale digital computer.[a.j] -
He developed the first high-level language called FORTRAN (FORmula TRANslator). [a,j] -
She developed a high-level language (for computing) called COBOL (Common Business-Oriented Language).[a.j] -
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] -
He developed de high-level language PASCAL.[a.j] -
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] -
He was thw one who novelized the new world and coined the term "cyberspace". [a,j]
