Cafe Scientifique

Café Scientifique is a forum for debating science issues and promoting public engagement with science. Audiences consist of people who are interested in science but generally never have the opportunity to discuss their views with, and ask questions of, someone "in the know".

Meetings generally start with a short talk from the speaker, who is usually a scientist or a writer on science, followed by a short break for drinks. This is followed by a session of about an hour for questions and answers and general discussion. Cafés are free although a voluntary contribution may be asked for to cover any expenses. (It does not pay fees to a speaker).

Meetings take place once a month on the second Wednesday of each month, starting at 7.30pm.

Next Meeting: Wednesday 10th December, 2014, 7.30pm

Place: The Old Bookroom, Hope Street Hotel

Title: Variation in length of day

Guest Speaker: Richard Holme, School of Environmental Sciences, University of Liverpool

“The Earth’s length of day varies on time scales of days or less (due to the atmosphere) to billions of years (due to tides from the moon). In this talk, I will focus particularly on intermediate time scales of decades, which are associated with change in motions in Earth’s fluid core. As a result, there is a strong link between such changes and the geomagnetic field. My recent work has particularly considered intradecadal variations, with a period of about 6 years – these variations are probably caused by motions of the Earth’s solid inner core. I discuss the evidence for such motions, and what further probes they provide concerning the structure and processes of the deep Earth.”
