The Antikythera mechanism (/ ˌ æ n t ɪ k ɪ ˈ θ ɪər ə / AN-tik-ih-THEER-ə, US also / ˌ æ n t aɪ k ɪ ˈ-/ AN-ty-kih-) [1] [2] is an Ancient Greek hand-powered orrery (model of the Solar System). It is the oldest known example of an analogue computer. [3] [4] [5] It could be used to predict astronomical positions and eclipses decades ...
In 2014 and 2015 it conducted robotic mapping surveys over the two ancient wreck sites, cooperating with the Woods Hole Oceanographic Institution and the Australian Centre for Field Robotics of the University of Sydney. Subsequent excavations of the Antikythera Wreck in 2014–2016 delivered new finds from the ship: wood elements from the hull ...
Derek John de Solla Price (22 January 1922 – 3 September 1983) was a British physicist, historian of science, and information scientist.He was known for his investigation of the Antikythera mechanism, an ancient Greek planetary computer, and for quantitative studies on scientific publications, which led to his being described as the "Herald of scientometrics".
The first digital electronic computer was developed in the period April 1936 - June 1939, in the IBM Patent Department, Endicott, New York by Arthur Halsey Dickinson. [35] [36] [37] In this computer IBM introduced, a calculating device with a keyboard, processor and electronic output (display). The competitor to IBM was the digital electronic ...
The way computers can understand is at a hardware level. This language is written in binary (1s and 0's). This has to be written in a specific format that gives the computer the ruleset to run a particular hardware piece. [68] Minsky's process determined how these artificial neural networks could be arranged to have similar qualities to the ...
Fragment of the Antikythera mechanism, a mechanical computer from the 2nd century BCE showing a previously unknown level of complexity. An out-of-place artifact (OOPArt or oopart) is an artifact of historical, archaeological, or paleontological interest to someone that is claimed to have been found in an unusual context, which someone claims to challenge conventional historical chronology by ...
One of the ancient lands the project aims to explore is Doggerland, which is thought to have thrived in North Sea region some 8,200 years ago. “Twenty-thousand years ago, the global sea level ...
As an analog computer does not use discrete values, but rather continuous values, processes cannot be reliably repeated with exact equivalence, as they can with Turing machines. [58] The first modern analog computer was a tide-predicting machine, invented by Sir William Thomson, later Lord Kelvin, in 1872. It used a system of pulleys and wires ...
