This lecture is part of a series of public lectures organised by Computing Science and Mathematics, University of Stirling.
We all have a general understanding of how and why daylight hours vary with the seasons, but it is perhaps not as simple as we think. For example, did you know that the evenings start getting lighter in December before we reach the shortest day? We shall try to explain this and other phenomena by looking at the mathematics of planetary motion and consider how the sun's position in the sky really varies throughout the year.
All are welcome to attend this free event, there is no need to book a place.
