Infinity is more than simply the biggest ever number, and even this simple description has caused problems for mathematicians throughout the ages. From the ancient Greeks to Newton, from Newton to present-day mathematicians such as Cristian Claude and Boris Pavlov of New Zealand, infinity has posed both practical and conceptual problems.
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.
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.
Are you interested in maths just for the fun of it? Or does mathematics seem irrelevant? Either way, this book is for you. Keith Ball is eager to share with his readers the way some of the numbers around us in the world work, and their uses.
It seems amazing that the universe could be characterised by a mere six numbers, yet, according to Astronomer Royal Martin Rees, this is the case. He makes an excellent case for the necessity of these numbers, though he does not show that they are the only numbers we need.
