2000-year-old 'computer'



Alternate science fans have known of this for a long time, the 2nd century BC Greek astronomical calculator with 37 gear-wheels. Now it has been deciphered using X-ray technology, and it is more impressive than previously thought.

The calculator function could add, multiply, subtract & divide.

It could align the number of lunar months with years and display where the sun and the moon appeared in the zodiac.

It also had a dial that predicted when there was a likely to be a lunar or solar eclipse, and it took into account the elliptical orbit of the moon.
