We can't actually talk about the history of computing without talking about two things: Their work helped Claude Shannon, an American electrical engineer, invented the first digital circuit that implements boolean algebra. We reached the modern conception of an abstract mathematical structure: Boolean algebra. They were all studying a systematic mathematical treatment of logic.
To help his father, a tax collector in Rouen, Pascal developed the Pascaline, which could handle multiplication and division through repeated additions or subtractions.Īfter a few years, philosophical mathematicians, including Leibniz and Lambert, started treating the operations of formal logic followed by George Boole, then Augustus De Morgan, and then others like Jevons, Schröder, and Huntington. We're in the middle of the European Renaissance, whose very first traces appear in Italy, where a polymath named Leonardo da Vinci conceived the first mechanical calculator, followed by the French mathematician Pascal Blaise. With the advent of the base 10 system and Arabic numerals from India, Europeans replaced the Roman numerals and moved away from abacus use. Starting from the 12th century, Europeans focused on studying Greek, and Arabic culture, and the Hindu-Arabic numerals were introduced to Europe through the writings of Al-Kindi and Al-Khawarizmi. This Arabic polymath gave birth to cryptanalysis through his very famous book and documented the first "crypto attack". In the 9th century, history knew the first hacker: Al-Kindi. The word algorithm comes from the name of the 9th-century Persian mathematician Al-Khwarizmi. This was when we started using algorithms. The Egyptians subsequently adopted the same system followed by the Greeks around the 5th century BC, the Romans around 300 BC, then the Chinese around 200 BC.Īfter mastering the first mathematical arithmetics, attention turned to using it to solve problems far more complex than counting, selling, or buying like automated reasoning and data processing. We nonetheless see the result of it: The first calculator - the first counting device used to count large numbers - the "Abacus". How do we, as humans, conceptualize a number as big as 1000 or 10000? And even though we might never know who came with the idea of abstracting numbers. In addition to the first love song and the first lullaby, the Sumerians invented the first calculator too. They're the distant ancestors of the base 60 that we still use when we count the seconds and minutes in each hour. These early writings made use of a sexagesimal system.
They have left the oldest known written texts. The Sumerians used the power of imagination and started abstracting the concept of numbers.
Over time, with bountiful harvests, their society became more prosperous, their economy kept scaling, and they felt the need for a computational system: an information processing system that can be represented mathematically. They were fishermen, herdsmen, and farmers. On the rivers of Tigris and Euphrates, more than 4000 years ago, lived an ancient civilization: The Babylonians and their ancestors, the Sumerians. This is the tale of computing, in which humans are heroes, and their greatest weapon is the imagination. Then we'll go back to modern times to talk about the first web server, virtualization, cloud computing, Docker, and Kubernetes. We'll talk about the technologies that have marked contemporary and modern history. I'm your host Kassandra Russel and today, we will navigate through history to discover how our ancestors made knowledge out of information.
#Abacus technology back door code
No doubt, your first lines of code rely on the combined outcomes of thousands of years of accumulated knowledge and wisdom. Maybe you were a gamer, and you blew the cartridges on your family computer? Do you remember the first time you touch the computer keyboard?ĭo you remember the typewriter clanging sound?ĭo you remember your first HTML rendered on the world wide web or your first "hello world" application?
