Until recently a lack of precision around China’s economic size was taken for granted but caused little lost sleep: room to expand and the pace of growth were self-evident, and everything beyond that was academic for most purposes. But today the pace and even direction of China’s growth is prone to volatility, and the nation is sizable enough to cause global disruption. This study reassesses China’s nominal economic size from the bottom up. It compares China’s practices with international standards and reviews the long-standing arguments about Chinese economic statistics to separate real concerns from distractions.

The medieval Catholic Church, widely considered a source of intolerance and inquisitorial fervor, was not anti-science during the Dark Ages -- in fact, the pope in the year 1000 was the leading mathematician and astronomer of his day. Called "The Scientist Pope," Gerbert of Aurillac rose from peasant beginnings to lead the church. By turns a teacher, traitor, kingmaker, and visionary, Gerbert is the first Christian known to teach math using the nine Arabic numerals and zero. In The Abacus and the Cross, Nancy Marie Brown skillfully explores the new learning Gerbert brought to Europe. A fascinating narrative of one remarkable math teacher, The Abacus and the Cross will captivate readers of history, science, and religion alike.

One of the most famous science books of our time, the phenomenal national bestseller that "buzzes with energy, anecdote and life. It almost makes you want to become a physicist" (Science Digest). Richard P. Feynman, winner of the Nobel Prize in physics, thrived on outrageous adventures. In this lively work that “can shatter the stereotype of the stuffy scientist” (Detroit Free Press), Feynman recounts his experiences trading ideas on atomic physics with Einstein and cracking the uncrackable safes guarding the most deeply held nuclear secrets—and much more of an eyebrow-raising nature. In his stories, Feynman’s life shines through in all its eccentric glory—a combustible mixture of high intelligence, unlimited curiosity, and raging chutzpah. Included for this edition is a new introduction by Bill Gates.
