For our February lecture, UCC Professor of Physics and Astronomy Dr Paul Callanan will talk about those mysterious objects so fundamental to astronomy, black holes. The date is Mon 10th Feb 2020 at 8 pm, and the venue is UCC. Please arrive 10 minutes early, or if you wish to join, then ideally at 7.40 if you can.
Understanding the nature of black holes remains one of the great challenges of modern astronomy.
More than 100 years ago, Einstein produced a remarkable theory which could be used predict the basic properties of black holes, but it was only this year, in 2019, when we finally got a glimpse of what a black hole really looks like. In this talk Paul will explore what we know about black holes, and what the most recent observations tell us about them. We will also see how Irish astronomers, 100 years ago this year, made observations which helped to show that Einstein’s theory of gravity was correct; an important milestone in the application of his theory to black holes and the universe at large.
For our January lecture, Master Mariner and nautical science lecturer Bill Kavanagh will explain how traditional methods were used to obtain a ship’s position by observing astronomical objects, and how such methods are being used again today in an era of global navigation satellite systems. The date is Mon 13th Jan 2020 at 8pm, and the venue is UCC. Please arrive 10 minutes early, or if you wish to join, then ideally at 7.40 if you can.
Bill is a committee member of Cork Astronomy Club. Captain Bill Kavanagh MA, FNI to give him his full title, lectures in the National Maritime College of Ireland at Ringskiddy. After a 20-year career at sea including 8 years in command, he moved ashore to start a new career in education and training. He currently lectures and co-ordinates the award year of the BSc honours degree in nautical science, and is an adjunct lecturer in research methods with Jade University of Applied Sciences, Oldenberg, Germany. While at sea, he navigated the Atlantic, Pacific and Indian Oceans using celestial navigation techniques.
