This unique book contains a biographical portrait, accounts of Chandrasekhar's role and impact on modern science, historical perspectives and personal reminiscences, several of which appeared in Physics Today, and reviews by leading experts in areas which Prof. Chandrasekhar pioneered. The reviews, which appeared in the Bulletin of the Astronomical Society of India, are either based on papers presented by scholars in the Chandrasekhar Centennial Symposium at the University of Chicago during 15-17 October 2010, or were additional reviews covering topics not represented at the conference by other distinguished astrophysicists. It provides a glimpse of some of the most exciting areas of modern astrophysics as a tribute to Prof Chandrasekhar on his birth centenary. A recent centenary celebration of Subrahmanyan Chandrasekhar, one of the few greatest astrophysicists of the 20th century, is the basis of this excellent, authoritative and important new volume. -- J P Ostriker "Princeton University" Chandra was exceptional in the range and depth of his researches, which extended over 60 years. This book offers authoritative assessments of his contributions, and their impact on our current understanding. Those who knew him and worked with him also offer their reminiscences, and fine vignettes of a man of extraordinary dedication and intellect. -- M J Rees "University of Cambridge" Chandra was not only a giant of 20th century science, he was a mentor and inspiration to generations of young researchers. My own career in the world of post-Newtonian gravity sprang directly from Chandra's work. And my own outlook on living life as a scientist was influenced by my encounters with him, first as his postdoc and later as a colleague. This book is a fitting and beautiful tribute to his many contributions to physics and astronomy. -- C M Will "Washington University" This volume is a fitting tribute to S Chandrasekhar (Chandra), one of the greatest astrophysicists of all time. It contains wonderful chapters, suitable for the casual reader, that describe Chandra the scientist, Chandra the warm human being, and Chandra's impact on science and on people. And it contains lucid chapters, designed for working scientists and advanced students, that describe the modern state of bodies of science that Chandra pioneered. I recommend this volume to the casual reader and the serious scientist alike. -- Kip S Thorne "California Institute of Technology" This unique book contains reviews by leading experts in areas which Prof. Chandrasekhar pioneered, as well as a historical perspective, a biographical portrait and personal reminiscences. The reviews, which first appeared in the Bulletin of the Astronomical Society of India, include papers presented by scholars at the Chandrasekhar Centennial Symposium held in the University of Chicago on 15 17 October 2010, and some additional reviews by other distinguished astrophysicists covering topics not represented at the conference.
