Steps forward in mathematics often reverberate in other scientific disciplines, and give rise to innovative conceptual developments or find surprising technological applications. This volume brings to the forefront some of the proponents of the mathematics of the twentieth century, who have put at our disposal new and powerful instruments for investigating the reality around us. The portraits present people who have impressive charisma and wide-ranging cultural interests, who are passionate about defending the importance of their own research, are sensitive to beauty, and attentive to the social and political problems of their times. What we have sought to document is mathematics' central position in the culture of our day. Space has been made not only for the great mathematicians but also for literary texts, including contributions by two apparent interlopers, Robert Musil and Raymond Queneau, for whom mathematical concepts represented a valuable tool for resolving the struggle between 'soul and precision.'

Lives of mathematicians allow us to glimpse not only the creative process at work in science, but to see how their lives were affected by the turmoil of the century in which they lived and worked Excerpts from literary works make evident how pervasive mathematics is in culture as a whole Contributions from leading mathematicians in Italy today help put recent developments in historical perspective Includes supplementary material: sn.pub/extras
