David Flannery lectures on mathematics at Ireland's Cork Institute of Technology

Sarah Flannery is a student at Cambridge University.

Originally published in England and cowritten with her father, "In Code" is "a wonderfully moving story about the thrill of the mathematical chase" ("Nature") and "a paean to intellectual adventure" ("Times Educational Supplement"). A memoir in mathematics, it is all about how a girl next door became an award-winning mathematician. photo insert.
