We review ``"The Cult of Pythagoras: Math and Myths" by Alberto A. Martinez, 2012. The book sets out a number of mathematical myths and dissolves them by a combination of checking historical sources and calculating results using the mathematics of the time. We pay particular attention to a chapter on division by zero. We record the earliest dates for particular solutions to the problem of division by zero and the ambition to have total mathematical systems.

The book “Geger Sepoy: Sejarah Kelam Perseteruan Inggris dan Keraton Yogyakarta (1812-1815)” was written against the background of the lack of in-depth study of geger sepoy. Some book sources that tell the events of the commotion are not written systematically, specifically, and chronologically. The writing of this is expected to add insight and detailed historical sources, chronology, and sharp analysis of the history of Yogyakarta, especially the commotion incident. The writing of this book is intended for the general public, especially for the millennial generation. This can refer to an effort to provide knowledge and lessons about the great history that has occurred in the "Keraton Ngayogyakarta" environment. In addition, this is can improve understanding for observers of the history of the land of Java and especially for observers of the history of the palaces in Java. This book contains objective information, although the sources studied are subjective. This can be seen from the content and discussion in the book that deliberately presented the history of the establishment of the Yogyakarta Palace and the history of the perpetrators of the commotion, including Sultan Sepuh, Sunan Pakubuwono IV, Sultan Hamengku Buwono III, Pangeran Prangwedono, Pangeran Notokusumo, Chinese Chief Tan Jin. Sing, Daendels and Raffles. In addition, it also explains the history of places that were silent witnesses of commotion, such as Vrendeburg Fort, Baluwarti Fortress, North Square, and South Square. This book has received attention to be reviewed because it has several supporting reasons, including 1) it has new sources of knowledge that support historical learning, 2) contains a systematic and structured discussion according to the chronology that occurs, 3) is objective in providing a discussion of the content, and 4) this also has received recommendations from several prominent figures in the Yogyakarta palace, including Drs. H.GBPH. Yudaningrat, MM. who is the son of Sultan Hamengkubuwono IX and KRT. H. Jatiningrat, SH., is the public relations officer of the Yogyakarta Palace.
