Book excerpt: The Historical Dictionary of Science and Technology in Modern China provides the most up-to-date information on science and technology in China from the late nineteenth century to the present. Special attention is given to the historical factors, scientists, and historical figures behind each scientific development. In particular, this book pays attention to the scientists who were persecuted to death or tortured during the Cultural Revolution (1966-1976), and whose scientific research was therefore tragically cut short. The historical dictionary provides information on science and technology in China from the late nineteenth century to the present including: a chronology; introduction; extensive bibliography; over 700 cross-referenced dictionary entries on major scientific and technological fields and sub-fields; entries on western scholars and educators who also impacted scientific achievements in China. This book is an excellent access point for students, researchers, and anyone wanting to know more about the science and technology in China.
