Among the most cherished artifacts of Oak Ridge National Laboratory is a small unassuming logbook with pages yellowed by time. The book was used by a group of researchers doing classified work in 1943 to record experiments at the X-10 Pile, a facility that later became known throughout the American scientific community as the Graphite Reactor. The book's most famous entry is dated November 4, 1943, with scrawled handwriting that reveals the author's excitement. The entry records a historic event of profound significance that had taken place in the hours just before dawn. In the hills of rural East Tennessee, the world's first powerful nuclear reactor had gone critical, ushering in the age of nuclear power and forever changing our assumptions about how we view science and its impact on our lives.
