The next Public Open Dome Event is on Thursday 26th April at the usual time of 7pm. 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.
Refreshments are available from 6:30pm. All welcome with no membership required. Suggested donation of £2 per adult is welcomed towards refreshments etc. Under 16’s welcome but must be accompanied by an adult please.
After the talk if the weather permits there will be opportunity for observing in the purpose built observatory. If not then a short guide to the night sky will follow with opportunity for a tour of the observatory for those who wish to view the facilities.
