First computer of the world | you must have to know About it.

World's first and oldest computer. 

  The world's first computer is a topic of much debate among historians, as there were many early calculating devices and machines that could be considered precursors to the modern computer. However, one of the most significant and well-known early computing machines is the Antikythera mechanism, a complex astronomical calculator built by the ancient Greeks over 2,000 years ago.

  The Antikythera mechanism was discovered in 1901 in the wreckage of a Greek merchant ship that had sunk off the coast of the island of Antikythera in the Aegean Sea around 80 BCE. It was initially thought to be a simple navigational device, but further investigation revealed that it was a sophisticated astronomical instrument capable of predicting the positions of the sun, moon, and planets, as well as lunar and solar eclipses, with remarkable accuracy.

  The mechanism consists of a complex system of gears, dials, and inscriptions, housed in a wooden case roughly the size of a shoebox. It had at least 30 bronze gears, many of them with triangular teeth, that were designed to mesh together to perform various calculations. Inscriptions on the mechanism's front and back surfaces provided information about the movements of celestial bodies and other astronomical phenomena.

  It is not entirely clear who designed or built the Antikythera mechanism, but historians believe that it was likely the work of a team of skilled craftsmen, including astronomers, mathematicians, and metalworkers. The mechanism may have been used to create astronomical calendars or to aid in predicting future celestial events.

  The Antikythera mechanism is a remarkable achievement of ancient engineering and technology, and its discovery has provided important insights into the sophistication of ancient Greek science and mathematics. It is a testament to the enduring human fascination with the workings of the universe and our desire to understand and predict its movements and rhythms.

  Today, the Antikythera mechanism is housed at the National Archaeological Museum in Athens, where it continues to inspire awe and wonder among visitors and scholars alike. Its legacy can be seen in the modern computer, which relies on many of the same principles of logic, calculation, and precision that were first developed by the ancient Greeks over two millennia ago.
