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.

Here the prolific math popularizer uses the different kinds of numbers (integers, reals, rationals, complex numbers, irrationals, transfinite cardinals) as hooks on which to hang a lot of little forays into various areas of mathematics. Some of the forays follow well-worn paths, and proofs are noticeably lacking. Good reading though. geen besprekingen | voeg een bespreking toe

At its heart, mathematics is about numbers, our fundamental tools for understanding the world. In Professor Stewart's Incredible Numbers, Ian Stewart offers a delightful introduction to the numbers that surround us, from the common (Pi and 2) to the uncommon but no less consequential (1.059463 and 43,252,003,274,489,856,000). Along the way, Stewart takes us through prime numbers, cubic equations, the concept of zero, the possible positions on the Rubik's Cube, the role of numbers in human history, and beyond! An unfailingly genial guide, Stewart brings his characteristic wit and erudition to b Geen bibliotheekbeschrijvingen gevonden. |

As an example: he talks about parities of permutations. He then says these show that the 15 puzzle is unsolvable, because the starting grid is an odd permutation of the required final grid but you can only make even permutations. But he doesn't show or explain how this is true. It's just a random fact that you learn and move on and can't actually apply.
