This is a lively and compact biography of P. M. S. Blackett, one of the most brilliant and controversial physicists of the twentieth century. Nobel laureate, leader of operational research during the Second World War, scientific advisor to the British government, President of the Royal Society, member of the House of Lords, Blackett was also denounced as a Stalinist apologist for opposing American and British development of atomic weapons, subjected to FBI surveillance, and named as a fellow traveler on George Orwell's infamous list. His service as a British Royal Navy officer in the First World War prepared Blackett to take a scientific advisory role on military matters in the mid-1930s. An international leader in the experimental techniques of the cloud chamber, he was a pioneer in the application of magnetic evidence for the geophysical theory of continental drift. But his strong political stands made him a polarizing influence, and the decisions he made capture the complexity of living a prominent twentieth-century scientific life.

Contemporary political theory has become alienated from politics. It often neither discusses concrete political events nor touches the world of political action. Stephen Eric Bronner wants to change that, and Ideas in Action takes a bold step in that direction. With elegance and power, Bronner surveys 20th century political traditions. In the process, he places theories and thinkers in their social, historical, and political contexts. His sweeping presentation is organized into four imaginatively articulated phases that signal the direction of political thinking in the twentieth century. Offering distinctive interpretations and criticisms, presenting a new internationalist perspective, Bronner imbues the text with original voices and primary sources from Adorno to Zetkin.
