Mitchell Waldrop, author of the critically acclaimed Complexity and formerly a senior writer at Science magazine, brings to life the story of J.C.R. Licklider (or "Lick" as he was generally known) — a gifted MIT psychologist with a proficiency in subjects ranging from electrical engineering to mathematics.
