They developed a large number of calculation methods, with the intention of streamlining them, based primarily on trial-error methods. they obtained multiplication tables, tables of squares and roots, tables of cubes and cube roots, exponential tables to obtain compound interest ... -
He Made a fundamental step in computer, wich development was the discovery of algorithms. -
They made an enormous contribution to the systematization of reasoning from 600BC to 300BC, in wich the formal principles of mathematics were developed. Characters like Plato, Aristotle or Euclid are the main representatives.
-
he is a greek philosopher that Presented deductive and systematized reasoning. -
He wass a greek philosopher, and he introduced the ideas or abstractions of the formal principles of mathematics that were developed in Greece. -
Is the character that has had the greatest influence on mathematicians throughout history, by establishing the axiomatic method. -
they used a different counting system so to perform arithmetic operations, the Greeks, Etruscans and Romans used the abacus
-
They first used the decimal numbering of position, we use comes from the Hindu numbering system who invented zero, and called it "sunya", which means "empty". -
Was the first person to write about Arabic numerals in the West. He had the opportunity to travel extensively through North Africa. There he learned Arabic numbering and positional notation with zero. -
Was the one who demonstrated that debts and similar phenomena could be treated with negative numbers. Until that point, mathematicians had believed that all numbers had to be greater than zero. -
Began to use letters to symbolize unknown values (variables) and thus laid the foundations of algebra -
Laid the foundations for mathematical formulation. -
He invented logarithms and made common the coma´s use in arithmetic operations. He also made an excellent discussion of theorems in spherical trigonometry. -
Invented a precursor to the calculation rule. He also made many trigonometry instruments and was one of the first scientifics to discover the terrestial magnetical declination. -
Designed and built what is considered the first digital calculator. Schickard's calculator allowed automatic additions and subtractions, and partially automated, multiplications and divisions. -
Discovered analytical geometry, and he also developed the cartesian geometry. He also invented the convencion of representating uknowns of ecuantions(with x, y, z....). -
Is generally regarded as the inventor of the calculator, 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. -
Was both an excellent theoretical thinker and a prominent pragmatic man. He was, along with Isaac Newton, the co-discoverer of calculus. -
Was one of the founding members of the Royal Astronomical Society of England. He proposed two computer machines moved by steam machines "The Difference Machine" and "The Analytical Machine". -
Built a highly specialized "differential" machine. It operated using punched cards containing series of operations and data. -
He established for the process of reasoning a symbolic representation. To do this he used variables that could only adopt two values "1" (true) and "0" (false), discarding any value of "half truth". Boole's ideas did not have a major impact over the next fifty years until the emergence of a thesis by Claude E. Shannon who demonstrated that the analysis of complex electronic circuits could be performed using Boole’s algebra. -
He had carried out important studies in formal logic and was collaborating with Hilbert in his attempts to axiomatize mathematics. -
Built a machine, similar to the Howard´s one, and several improved versions were built successively.. -
Designed the first fully electronic digital computer with the help of an undergraduate student named Clifford E. Berry. -
Collaborating with a group of IBM engineers, designed and built an electromechanical machine named Mark 1capable of multiplying two numbers in six seconds and dividing them by twelve -
Was the designer of ENIAC,wich was the first large-scale digital computer.His work influenced an explosion in computer development in the late 1940s everywhere in the world. -
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.
