### Description

It is a sad fact that many people believe that mathematics is about

doing arithmetic and memorizing formulas. However, if these people

were to ask a mathematician what their profession is about they

might be surprised by the answer. “A mathematician, like a painter

or poet, is a maker of patterns. If his patterns are more permanent

than theirs, it is because they are made with ideas.” So said the

number theorist G. H. Hardy in his 1940 essay ‘A Mathematician’s

Apology’, and in this talk I will attempt to convey this alternative

point of view using a series of examples of visual mathematics. Each

example will take the form of an easy-to-explain statement about

numbers or geometric shapes, followed by a purely visual proof of

the statement. The success of the talk may be judged by the number

of ‘Eureka!’ moments it generates in the audience.
