Did you know that every instant, gravity waves from outer space are stretching and squeezing you - and everyone and everything else in the universe? Learning more about this mysterious radiation will help us to probe the structure and origins of the universe, explains Anita Barnes.
Most people think that mathematics consists of either just arithmetic, or a collection of very abstract and technical topics which the layperson has no chance of grasping. But this really is not true: of course many areas are too technical for the non-mathematician, but there are also many beautiful and non-trivial facts which can be expressed in ordinary language for everyone to appreciate.
"As long as a branch of science offers an abundance of problems", proclaimed David Hilbert, "so is it alive". These words were delivered in the German mathematician's famous speech at the 1900 International Congress of Mathematics. He subsequently went on to describe 23 problems which he believed would spur on mathematical thought for the upcoming century.
"Mathematical Apocrypha" is, as its subtitle intimates, a book of stories and anecdotes about mathematicians and the mathematical. However, in contrast with many books about mathematicians, Steven Krantz focuses on contemporary figures such as Wiener, Littlewood and Hardy, and says very little about the usual myths regarding Pythagoras, Descartes or Euler.
We live in a world that obeys many physical laws, and that can be modelled by a variety of mathematics. It is surprising what a variety of problems can be described by very similar models. Robert B. Banks does not concentrate on the most common examples of applied mathematics, but instead covers a fascinating selection of topics as varied as the US national debt, the Eiffel Tower, and the flight of golf balls.
