Shing-Tung Yau is a name familiar to most mathematicians and theoretical physicists, through his fundamental work in geometric analysis and the theory of Calabi–Yau manifolds. Professor Yau is also known to the educated public, particularly in China, by his many expository works, his publications in the news media, and his tireless work over the years in promotion of mathematics and mathematical education.

This volume presents collected impressions of Yau and his mathematical world, written by his friends, students, and colleagues from past and present. Together, these impressions paint a vivid portrait of an extraordinary kind of scholar.
