Top customer reviews
Each of the books in this series is dedicated to a particular branch of mathematics - in this case, we have `cryptanalysis'.
'Is maths making you miserable?
Are you confused by ciphers and baffled by binary?
Let 'Murderous Maths' take the agony out of cryptanalysis and you'll be a code-cracking genius in no time.
The Pure Mathematicians explain how a computer can make buying shoes safe and the secrets of ENIGMA are revealed.
Plus, find out Dolly Snowlips' waist size and a tatty tablecloth can help the Gangsters with their latest money-making scheme.'
The colourful, humorous cover opens to 160 pages, split over 11 chapters:-
A sneaky start
The Enigma machine
The uncrackable credit card code
written in a variety of fonts in the usual Kjartan Poskitt entertaining style, e.g.:-
'As you launch yourself into this extraordinary book, notice that arranged within the main text there are many cunningly concealed kinds of trick messages, only you don't see any just yet.
Hah! Did you spot it? No? We hate to tell you this but you have `already' read a secret message.
Yes indeed, a hidden announcement of national importance was sneaked into that first sentence!
It uses one of the easiest sorts of codes, but don't worry if you didn't see it as we'll explain it soon............'
Black and white illustrations/cartoons throughout.
Maths as you have never seen it before!
