11 September Meeting – 7pm

September 9th, 2010 | Author: admin

Meet at Acadia University, Huggins Science Hall, Room 202

Main Presentation:
The Tides of Fundy
by Roy Bishop
Roy was asked to be the speaker at the closing banquet the 2010 General Assembly of the Royal Astronomical Society of Canada held in Fredericton in July, and that his topic be The Tides of Fundy. He will repeat that presentation at MAG this Saturday. Roy spoke on tides at the first meeting of MAG 16 years ago (1994 November 12). The 2010 version of his presentation on tides has been updated, in both content (better physics and astronomy) and technology (PowerPoint)!

Come and join us for casual astronomy talk and interaction after Roy’s talk.

Navigation: Determining position on the third planet

by Roy Bishop

The surface of a planet is primarily two dimensional, thus two coordinates suffice to specify position. Several techniques of increasing precision have been used to determine position and thereby enable the preparation of maps, promotion of commerce, and expansion of empires. Latitude, the angle of the plumb bob direction to Earth’s axis of rotation, is relatively easy to establish using the stars. Longitude, location in the direction of Earth’s rotation, is both arbitrary and not as easy to determine. Techniques for finding latitude and longitude have been developed over the past five centuries, the most recent advance occurring within our lifetimes.
