(25) Antikythera MechanismMar 7, 2013

In 1901, the ancient Greek wreck was discovered in the waters of Antikythera Island. Among the items retrieved from the wreck was a decayed and complicated mechanism. The mechanism is called 'Antikythera Mechanism', which was restored in 2006 after scientific research and study for decades. It includes 30 gears to predict the motion of the sun, the moon and five planets, and the eclipses of the sun and moon. It was also used to calculate leap year and the year of the Olympic Games. It was seemingly made in the 2nd century B.C., 100 years ago before the Julian calendar was instituted. When looking at this excellent mechanism, we can feel the passion of those who made full use of mathematics and techniques.
