Plimpton 322 is a Babylonian clay tablet, notable as containing an example of Babylonian mathematics. It has number 322 in the G.A. Plimpton Collection at Columbia University. This tablet, believed to have been written about 1800 BC, has a table of four columns and 15 rows of numbers in the cuneiform script of the period. -

The Mesoamerican calendars are the calendars devised and used by the pre-Columbian cultures of Mesoamerica. In addition to the control of the passage of time, Mesoamerican calendars were also used in religious ceremonies, in social rituals and in divination -
John Napier
Napier's bones, also known as Napier rods or canes, were developed by the inventor of logarithms to perform multiplications, divisions and square roots. Napier's bones consisted of an individualized and particular version of the multiplication tables. -
Wilhem Schickard
The calculator clock or also called the Schickard machine is an automatic machine created in 1623 by the German mathematician Wilhelm Schickard. -
Edmund Wingate
The calculation rule is a calculation instrument that acts like an analog computer. It has several mobile numerical scales that facilitate the fast and convenient performance of complex arithmetic operations, such as multiplications, divisions, etc -
Blaise Pascal
The pascalina was the first calculator that worked on wheels and gears, invented in 1642 by the French philosopher and mathematician Blaise Pascal. The first name he gave his invention was "arithmetic machine." Then he called it "Pascalina wheel", and finally "Pascalina" -
Sir Samuel Morlan
A mechanical calculator was an object or calculation and calculation system that bases its operation on a mechanical principle to return the results of an arithmetic operation. -
Wilhelm Leibniz
1ª Máquina de cálculos aritméticos= A Leibniz wheel or Leibniz cylinder is a cylinder-shaped drum, with a set of teeth of incremental length to which a counting wheel is attached. It was used as the calculation engine of a class of mechanical calculators. -
Joseph Jacquard
The perforated card or simply card is a sheet made of cardboard that contains information in the form of perforations according to a binary code. These were the first means used to enter information and instructions to a computer in the 1960s and 1970s -
Charles Babbage
The Analytical Engine was a proposed mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage. It was first described in 1837 as the successor to Babbage's difference engine, a design for a simpler mechanical computer. -
Ada Lovelace
In 1834, Babbage had plans for the construction of a new type of calculating machine, a general analytical machine. ... Ada was the first person in the world to describe a general programming language in interpreting Babbage's ideas even better than himself. -
George Boole
El álgebra de Boole y la codificación binaria- Boolean algebra, also called Boolean algebra, in digital electronics, computer science and mathematics is an algebraic structure that schematizes logical operations The binary code is the coding system used for the representation of texts, or computer instruction processors, using the binary system (two-digit number system, or bit: "0" and "1"). -
Herman Hollerith
The tabulating machine is one of the first computer application machines.Herman Hollerith had developed an electric punch card system based on Boolean logic, applying it to a tabulation machine of his invention. The Hollerith machine was used to tabulate the census of that year in the United States, during the total process no more than two and a half years. Thus, Hollerith created the Tabulating Machine Company. -
Leonardo Torres Quevedo
Built in 1894 by Leonardo Torres Quevedo, with funding from the Royal Academy of Sciences, thanks to the presentation of a memory with the description of the machine that would allow solving algebraic equations.
Algebraic Machine of Torres Quevedo
The objective of the machine was the continuous and automatic obtention of polynomial function values. Being an analog machine, the variable can go through any value (and not just some discrete default values). -
Ejercito alemán
Máquina Enigma= Enigma was the name of a rotor machine that allowed it to be used both to encrypt and decrypt messages. -
Vannevar Bush
1er Analizador Diferencial= The Differential Analyzer (in English, Differential Analyzer) was a mechanical analog computer designed to solve differential equations by integration, using wheel and disk mechanisms to perform the integration. -
Alan Turing
Máquina Universal de Turing= Universal Turing Machine ... It is also known as a universal computing machine, universal machine. In terms of computational complexity, a universal multi-tape Turing machine only needs to be slower by a logarithmic factor, compared to the machines it simulates. -
John Atanasoff
ABC= 1ª computadora electrónica y digital automática- The Atanasoff Berry Computer (ABC) was the first automatic electronic and digital computer that was used with numbers and letters (although this is now attributed to Konrad Zuse's Z1 completed in 1938). -
Konrad Zuse
Z1= The Z1 was a mechanical computer designed by Konrad Zuse from 1936 to 1937 and built by him from 1936 to 1938.
Z2= The Z2 was a mechanical and relay computer completed by Konrad Zuse in 1940.
Z3= The Z3 was a German electromechanical computer designed by Konrad Zuse.
Z4= The Z4 was the world's first commercial digital computer, designed by German engineer Konrad Zuse and built by his company Zuse Apparatebau in 1945. -
George Robert Stibitz
Calculadora de números complejos=CNC= Numerical control is the automated control of machining tools and 3D printers by means of a computer. A CNC machine processes a piece of material to meet specifications by following a coded programmed instruction and without a manual operator. -
Norbert Wiener
Cybernetics is the interdisciplinary study of the structure of regulatory systems. In other words, it is the science that studies energy flows closely linked to control theory and systems theory. -

The abacus is an instrument that serves to perform simple arithmetic operations1 (addition, subtraction, division and multiplication and other more complex ones, such as calculating roots). It consists of a wooden box with parallel bars that run movable balls, useful also to teach these simple calculations.
