Speakers: Prof Alan Davies

In four previous IOP lectures Professor Davies described a variety of atmospheric optical phenomena and the elementary physics and mathematics which describes them. In this talk he will give a brief review and expansion of the ideas already presented.
This will lead to his describing other optical effects and he will start with phenomena associated with the varying density of the atmosphere. He will say some more about how dust particles and clouds in the sky lead to a variety of spectacular colour effects. Finally he will explain a variety of shadow effects including crepuscular rays. Everybody is aware of the earth’s shadow in a lunar eclipse, however much less appreciated is the possibility of seeing the shadow against the earth’s atmosphere.
Alan Davies is Professor of Mathematics at the University of Hertfordshire
