Why is the sky blue and why are sunsets red? When can I see a
rainbow? Why is the moon sometimes visible in daylight? In Out of
the Blue skywatcher John Naylor offers practical advice about where
and when you can expect to see natural phenomena, what you will see
and how to improve your chances of seeing it. Naylor takes in both
the night and the day sky, and deals only with what can be seen
with the naked eye. Drawing on science, history, literature and
mythology, and assuming only basic scientific knowledge, Out of the
Blue is for everyone who enjoys being outdoors and who feel curious
or puzzled about things optical and astronomical. John Naylor was
born in England, but spent his childhood in Peru. A graduate of
London University with a degree in philosophy, he teaches physics
at a secondary school in London.
