halfmanhalfbook's review against another edition
3.0
Think of a number, any number...
Multiply it by 2
Add 10
Then divide by 2
Subtract your original number
And I will tell you your answer later on.
Stewart has a knack of making complicated and difficult mathematical concepts easy to comprehend and understand. In this book he introduces us to the numbers that we come across day in and day out. Some will be familiar, zero, one and Pi for example. Other are less familiar, from logs (not trees) to that strange areas of mathematics that encompass imaginary numbers and the vastness of infinity.
In this journey we venture through the primes, peers back into the history of mathematicians, informs us what is a rational number, traverses the circular numbers, plumbs the depths of fractals and explains the birthday paradox. There is a brief sojourn to the really small, before seeing the really really large numbers stretching away in the distance, and reaching the restaurant at the end of the universe with a reservation at table 42.
Occasionally complex, most of this is written with the layman in mind. Stewart writes with clarity on a subject that he knows and loves, and what really comes across is his enthusiasm to get other to love, or at the very least like maths once again.
Oh, and the answer is 5.
