Many people find no beauty and pleasure in maths - but, as
Lewis Dartnell explains, our brains have evolved to
take pleasure in rhythm, structure and pattern. Since these
topics are fundamentally mathematical, it should be no
surprise that mathematical methods can illuminate our
aesthetic sense.
Did you know that you can't average averages?
Or that Paris is rainier than London ... but it rains
more in London than in Paris? Andrew Stickland
explores the dangers that face the unwary
when using a single
number to summarise complex data.
Most of us have heard of "stealth" - a technology used
by the military to disguise craft from enemy radar. But
nature's stealth fighters are not so well known -
creatures that use motion camouflaging to approach their
prey undetected. Lewis Dartnell looks at the vector mathematics
behind the phenomenon.
Mathematician and physicist John Baez declares
himself fascinated by exceptions in mathematics. This
interest has led him to study the octonions, and, through
them, to find out more about the origins of complex numbers
and quaternions. In the second of two articles, he talks
about the characters of the different dimensions,
beauty and utility in mathematics, and just why he likes
dimension 8 so much.
Jose Munoz explains how engineering can allow
you to explore the unknown, from understanding
how mechanical structures bend to investigating
the way genes affect the
shape of embryos.
