Updated! April 26th Open Dome - The Antikythera mechanism


Recommended Posts

There is a change to the advertised talk this coming Thursday. Start time 7pm as previous but details of the talk ammended as follows:

 

Dr Maria Pavlidou of Birmingham University will be talking about “The Antikythera mechanism”

The Antikythera mechanism is an ancient Greek analog computer and orrery used to predict astronomical positions and eclipses for calendar and astrological purposes decades in advance. It could also track the four-year cycle of athletic games which was similar to an Olympiad, the cycle of the ancient Olympic Games. Detailed imaging of the mechanism suggests that it had 37 gear wheels enabling it to follow the movements of the moon and the sun through the zodiac, to predict eclipses, and even to model the irregular orbit of the moon, where the moon’s velocity is higher in its perigee than in its apogee.

 

Doors open at 6:30pm with refreshments available. A suggested donation of £2 per person would be welcomed towards running costs. Under 16's welcome but must be accompanied by an adult please.

 

After the talk there will be opportunity for observing if clear, or a short guide to the night sky if not. There will also be an opportunity to tour the observatory for anybody wishing to do so.
