While the Ancient Greeks gave the mathematical basis of perfect intervals in music over two and a half thousand years ago, there are still many considerations (not all understood) that influence and affect how we experience music today. These include culture, memory, familiarity, setting, acoustics, physics, mathematics and psychology – to name but a few. In this introductory talk (with many audio examples), I’ll look at just one aspect – the physics and mathematics of sound. From this, can we scientifically explain concepts like dissonance/consonance in music? How is this related to the Western 12-tone scale? What has this to do with MP3 compression? Or maybe music just transcends any crude scientific reductionism?
NLO members, John Bardsley, Bill Hitchings & Pete Youd have spent the last year restoring this wonderful 19th century Orrery to full working order. It was donated by Howard Anderson, a member of the British Sundial Society.
On arrival it consisted of a painted wooden base, the Sun and Mercury and the clockwork mechanism but no other planets. Pete restored and french polished the base. John who is a master watchmaker/repairer, worked on the mechanism,repaired the gears and made new arms. Bill restored the Earth and the Cambridge Design Partnership 3D printed Saturn and the remaining planets (this orrery also includes asteroids, Ceres, Pallas, Vesta).
It is believed to have been made in Germany circa 1895, but we would be grateful for further information about this remarkable model of the solar system.
The Norman Lockyer Observatory will be open to the public for viewing the Transit of Mercury
from 12.00pm on Monday 9th May 2016. This is quite a rare event happening just 13 times each century.
Using our telescopes we will be able to safely see the small planet transiting across the face of the Sun.
There is no charge for attending and visitors are welcome to drop in at any time during the day
(providing the Sun is shining!) to join us for observing this rare event.
