"Choudhuri gives us a condensed history of the study of the sun and of sunspots over the past few centuries back to Galileo Gailiei, whose discovery of the Sun's 27-day rotation marked the serious start of solar physics. The remarkable tale includes skilled amateurs as well as professional academics, the rivalries between the main players, and a probable husband-wife murder-suicide thrown into the mix. Yes, there is a lot in the story of studying the sun, and the author does a masterful job of making it a fascinating read." -- Simon Constable, Forbes "A fascinating, engaging and enjoyable book." -- Contemporary Physics "This captivating book immerses the readers in the development of solar physics as though they were participating in a theatre play. Many personal memories provide fascinating links to the historical development of solar science. It is a book hard to put down once started!" -- Pascal Demoulin, Observatoire de Paris "Going through Nature's Third Cycle - A Story of Sunspots by Arnab Rai Choudhuri is equivalent to having a ringside view of the gradual unveiling of one of the abiding mysteries associated with the Sun . In the academic community, Rai Choudhuri is known as a wonderful teacher and a brilliant scientist.

He uses his expertise as a teacher to take the readers effortlessly through the complexities of solar physics." -- Sushan Konar, Resonance "This [book] establishes new (unprecedentedly high) standards of scientific writing . Already in the beginning, the reviewer has to tell that this book is among the best he has ever taken in his hands . It should be stressed that reading this book will be easy for geoscientists . [and] will attract more young people to science." -- Dmitry A. Ruban, Zentralblatt fuer Geologie und Palaeontologie.
