The science of rainbows

2015 is The year of Light so what better way to celebrate than to look at that most well-known and loved phenomenon:  The rainbow.

Physical Sciences and Astronomy: a matter of scale

February 15 2015

Ideas invited

It is around this time of year that we start thinking about next year’s programme.  If you have any special requests that you would like us to consider then please complete the form and send it over.

What is an Aurora?

What causes It?

What do we know about the Aurora?

Can we see any from the UK?

We shall see a wide variety of rainbow phenomena some of which will be familiar to all of us, others will be not so well-known.  We shall explain the double bow and why the colours are always in the same order.  We’ll see rainbows in places other than in the sky and we shall answer the question “Can you see that rainbow?”

Alan Davies is Professor of Mathematics at the University of Hertfordshire where his teaching and research has been in numerical applied mathematics.  In 2006 he retired from his position as Head of Department and now concentrates on outreach activities.  He has, for more than twenty years, had a very close association with Royal Institution Mathematics

Masterclass Programmes in Hertfordshire, London and elsewhere.  He presents a wide variety of topics to young people of all ages from primary through secondary into higher education and gives public lectures to general audiences on popular applications of mathematics and physics.
