�I�m an explorer, OK? I like to find out!�
   One of the towering figures of twentieth-century 
  science, Richard Feynman possessed a curiosity that was the stuff of legend. 
  Even before he won the Nobel Prize in 1965, his unorthodox and 
  spellbinding lectures on physics secured his reputation amongst students and 
  seekers around the world.
  It was his outsized love for life, however, that earned him 
  the status of an American cultural icon -
  here was an extraordinary intellect devoted to the proposition that the 
  thrill of discovery was matched only by the joy of communicating it to others. 
  In this career-spanning collection of letters, many published here for the 
  first time, we are able to see this side of Feynman like never before.
  Beginning with a short note home in his first days as a 
  graduate student, and ending with a letter to a stranger seeking his advice 
  decades later, Perfectly Reasonable Deviations from the Beaten Track 
  covers a dazzling array of topics and themes, scientific developments and 
  personal histories.
  With missives to and from scientific luminaries, as well as 
  letters to and from fans, family, students, crackpots, as well as everyday 
  people eager for Feynman�s wisdom and counsel, the result is a wonderful de 
  facto guide to life, and eloquent testimony to the human quest for knowledge 
  at all levels. Feynman once mused that �people are �entertained� enormously by 
  being allowed to understand a little bit of something they never understood 
  before.�
  As edited and annotated by his daughter, Michelle, these 
  letters not only allow us to better grasp the how and why of Feynman�s 
  enduring appeal, but also to see the virtues of an inquiring eye in 
  spectacular fashion. Whether discussing the Manhattan Project or developments 
  in quantum physics, the Challenger investigation or grade-school textbooks, 
  the love of his wife or the best way to approach a problem, his dedication to 
  clarity, grace, humor, and optimism is everywhere evident.
