Our little systems have their day; They have their day and cease to be; They are but broken lights of thee, And thou, O Lord, art more than they. Tennyson (1850)
I would like to thank my former colleagues at the Jet Propulsion Laboratory, Chris A. Curzon, Orwyn Sampson, and William M. Owen, Jr., my parents, George and Rita, and David Groseth for carefully reviewing the text and making many valuable suggestions. Kimo Yap scanned the book cover image (along with some other images in the Web pages).
Dedicated to my parents, George and Rita
