Casti, Nature) 'A paean to intellectual adventure.' (Times Educational Supplement) 'An engaging, almost playful, book in which the reader is encouraged to spend lots of time working out mathematical puzzles are interwoven with a narrative of Sarah's annus mirabilis. Sarah's story should serve as an inspiration for all young people contemplating a life in mathematics.but for anyone interested in the human spirit and its boundless capacity for innovation and imagination.' (John L. The amazing life of this young woman and her incredible mathematical journey, told here by herself and her father-tutor, are sure to captivate you like few other human stories!' (Eli Maor, author of To Infinity and Beyond and e: The Story of a Number' 'A wonderfully moving story about the thrill of the mathematical chase. What every aspiring young scientist and mathematician needs: love, humor, inspiration and.a copy of this book.' (Richard Mankiewicz, author of The Story of Mathematics) 'Whether you're a math fan or have always shied away from it, you'll be hooked on Sarah Flannery's story from the very first page. 'A TERRIFIC ADVENTURE IN CRYPTOGRAHY.' (Simon Singh, author of Fermat's Enigma and The Code Book' 'A veritable mathematical travelogue. A memoir with mathematics, In Code tells how the girl next door moved from the simple math puzzles that were the staple of dinnertime conversation to number theory, the Sieve of Eratosthenes, and Femat's Little Theorem Finally culminating in a passion for public key cryptography, and the creative breakthroughs that led to her own discoveries. How did Sarah, an above average student who loves 'maths' but adamantly refuses epithets like brilliant or genius, astound the world with an algorithm In Code, cowritten with Sarah's father and teacher, David Flannery, is a surprising and heartwarming story that will have readers cheering Sarah on. Her story was splashed across the front page of the London Times - and suddenly this teenager from Country Cork had an international reputation. Her research and discoveries in Internet cryptography won her both Ireland's Young Scientist of the Year and European Young Scientist of the Year awards. From the Publisher: From puzzles on the blackboard in an Irish country kitchen to her acclaimed Cayley-Purser algorithm, Sarah Flannery has made an extraordinary beginning as a mathematician.
