Product description

Amazon Review

Sarah Flannery is the Irish teenager who last year stunned the world by inventing a way of making public-key encryption much more efficient. Given that this is the underlying security technology of e-commerce, that is an achievement that many of the world's leading research laboratories would have been proud of. That it came from a modest, well-adjusted, cheerful Irish teenager is nothing short of miraculous.

In Code is the story of how she did it, and of what happened to her and her family as a result. It's an engaging, almost playful, book in which the reader is encouraged to spend lots of time working out mathematical puzzles set by the authors. This is not sadism on their part, but a cunning plot to get the reader thinking like a cryptographer. It's also a reflection of the way the Flannery family works, for it's clear that puzzle-solving is as much a part of their communal life as eating. The puzzles are interwoven with a narrative of Sarah's annus mirabilis, in which she found a stupendously clever way of easing the computational load which public-key cryptography imposes on machines. What's striking about this account is its level-headed, self-deprecating, eminently sane tone. This is a girl whose head hasn't been turned by fame. And that, in a way, is her greatest achievement.--John Naughton

Synopsis

At the age of 16, the author became the Irish Young Scientist of the Year with a highly innovative, speedy and secure system of encoding data on the Internet. An inspiring account of a mathematical education with many puzzles and examples it offers into cryptography and numeracy.
