The first A–Z resource on the history of science from 1900 to 1950 examining the dynamic between science and the social, political, and cultural forces of the era. Though many books have highlighted the great scientific discoveries of the early 1900s, few have tackled the wider context in which these milestones were achieved. Science in the Early Twentieth Century covers everything from quantum physics to penicillin and more, including all the major scientific developments of the period, detailing not only the scientists and their work, but also the social and political forces that dominated the scientific agenda. Over 200 A–Z entries chronicle the landmark scientific discoveries and personalities of the period, including such scientific giants as Albert Einstein and Marie Curie. Placing science firmly within its cultural context, this thoroughly researched, accessible resource takes a uniquely interdisciplinary approach, making it an invaluable text for scientists, educators, students, and the general reader.
