Before the machine
Early calculation devices: devices were used to perform calculations, such as the abacus, which dates back to at least 2,500 B.C.
John Napier and the Napier bones: in the seventeenth century he developed 'The Napier bones' which were wooden tablets engraved with numbers and used to perform mathematical and logarithmic calculations.
Gottfried Wilhelm Leibniz and the calculating machine: In the seventeenth century, this German philosopher and mathematician contributed to the development of calculating machines, designing a machine that could multiply, divide and extract square roots.
Joseph-Marie Jacquard and programmable looms: developed an automatic loom that used punched cards to control the weaving pattern.
The first calculators
Pascal's Calculator (Pascaline): it was designed to perform addition and subtraction automatically, it was one of the first mechanical calculation devices and was used in accounting and astronomical navigation.
Leibniz's calculating machine: it was based on the decimal system and used a cogwheel mechanism to perform addition and multiplication operations.
Babbage Machine: Charles Babbage designed various machines such as the Difference Machine and the Analytical Machine.
Scheutz calculator: it was developed by the Swedish mathematician per-Georg Scheutz and his son, it used punched cards to perform multiplication and division operations.
The punch card
punch card marked the beginning of the transition toward automated storage and processing of data, directly influencing the design og the first computers and computer systems.
Although obsolete, punch cards are a milestone in the history of computing, laying the foundation for current technologies. They represent the evolution from mechanical to digital systems and are a reminder of how early limitations drove technological innovation.
