From: TerryMoselaol.com Date: 18 November 2006 13:29:55 GMT Subject: IAA Leonid watch, AP on RTE, Structure of Matter, Armagh lecture Hi all, 1. OBSERVING EVENING + LEONID WATCH: The Irish Astronomical Association will be holding an observing evening tonight, weather permitting, at Delamont Country Park, just South of Killyleagh on the road to Downpatrick, Co Down. It's a great dark-sky site, with plenty of room for parking & observing. The barrier at the entrance will be open until 9 p.m. this evening, so be there before 9 if you want to get in. The barrier opens automatically on exit, so you can get out any time you want. There will be ordinary telescopic & binocular observing first, followed by a session on the Leonid meteors, hopefully lasting right through to the "Asher - McNaught Peak" at about 04.45. This is expected to be a brief but intense burst of activity of faint meteors, when hourly rates of up to 120 or 150 might be seen. But note that the main burst of activity won't last long: one prediction is that the 'Full Width Half Maximum" will last about 40 minutes; in other words the level will be at least half of the maximum rate for a period of 40 minutes centred on 04.45. Extending that prediction slightly might indicate a rate of at least 40 per hour from about 04.15 to 05.15, and over about 30 per hour from 04.00 to 05.30. But please note that most of the meteors are expected to be faint, so you will need to have a very dark sky to see that rate! You can get a final check on whether it's going ahead by checking the IAA website, Bring a flask of hot tea or coffee to keep you going, and wrap up REALLY warm! 2. ARMAGH PLANETARIUM ON RTE: Have a look at the Armagh Planetarium interview that was aired on Irish RTE prime time news. The interview covers the latest imagery from Mars, ESA missions, meteorites and lots more. Link 3. "String theory, fermions and field theories" A lecture for those interested in the fundamental structure of matter, which may eventually lead to a 'Theory of Everything', linking gravity to the other three fundamental forces of nature. I imagine that this is one for those with a good grounding in physics and maths! "Award-winning Dutch physicist, Prof Robbert Dijkgraaf, is giving a specialist public lecture in Dublin on Wednesday, November 22nd. Dijkgraaf, who studied for his PhD under Dutch Nobel laureate, Gerard 't Hooft, is now a professor at the University of Amsterdam, having previously worked at the Princeton Institute for Advanced Study. In 2003 he received the highest scientific award in the Netherlands, the NWO Spinoza Prize. Dijkgraaf's Dublin talk is entitled: Gauge Theories and Free Fermions (the abstract below). Admission free, all welcome. Wednesday 22nd November at 3.30 pm (NOTE time), DIAS, 10 Burlington Road, Dublin 4 For more information on DIAS and its events, see Link Abstract: Many exact solutions of 4d supersymmetric gauge theories can be formulated in terms of 2d free fermion systems. This talk will show how ideas from string theory naturally lead to such a description that connects instanton computations, conformal field theories, and integrable systems. 4. ROBINSON LECTURE, ARMAGH: A reminder: The 2006 Robinson Lecture will be delivered by Professor Eric Priest FRS, of the School of Mathematics and Statistics at the University of St. Andrews. The lecture, entitled "Our Enigmatic Sun" will begin at 7.30 pm on Friday 24 November 2006 in The Synod Hall, Abbey Street, Armagh, and is scheduled to end at 9.00 pm, followed by light refreshments. The abstract of the lecture is: "For centuries mankind in societies such as the ancient Egyptians worshipped the Sun, and today modern observations from space have shown that the Sun is much more puzzling than we realised. Indeed, most of the fundamental properties of the Sun (which have important implications for the rest of astronomy) are not yet understood. The lecture will introduce you to the main properties of the Sun and will describe many of the modern puzzles, using the latest images and movies. It will also describe a trip the author took to Egypt to watch a solar eclipse, and will describe observations of huge ejections of mass from the Sun and their effects on the Earth. Attendance at the Robinson Lecture is free, but if you would like to attend, please contact the Armagh Observatory in order to obtain tickets. Please write, telephone or send an e-mail to: Mrs Aileen McKee, Armagh Observatory, College Hill, Armagh, BT61 9DG; Tel: 028-3752-2928; Fax: 028-3752-7174; e-mail: ambnarm.ac.uk. Further information about the 2006 Robinson Lecture is available at: Link In addition Professor Priest is delivering the Robinson Schools Lecture in the Royal School, College Hill, Armagh, at 2.00 pm on Thursday, 23 November 2006. Teachers and pupils who would like to attend should contact Warren Fowles, The Royal School, College Hill Armagh. Tel.: 028 3752 2807; e-mail: sfowles830royalschool.armagh.ni.sch.uk.
