The Antikythera Analog Computer (A2, passive voice)
The Antikythera Analog Computer
A long time ago, around 2000 years, people built a very special machine. This machine is called the Antikythera Mechanism. It was found in 1901 near the Greek island of Antikythera. The machine was in a shipwreck under the sea.
The Antikythera Mechanism is the first known analog computer. It helped people to study the stars and planets. The machine had many small gears inside. When people turned a handle, the gears moved and showed the position of the Sun, Moon, and planets. It also showed when there would be eclipses.
Scientists were very surprised when they found the machine. It was very advanced for its time. Today, people use computers to study space, but the Ancient Greeks used this machine!
The Antikythera Mechanism is now in a museum in Athens. It is very old, but it still helps us understand history and technology.
