Astronomy and Astrophysics Abstracts, which has appeared in semi-annual volumes since 1969, is de voted to the recording, summarizing and indexing of astronomical publications throughout the world. It is prepared under the auspices of the International Astronomical Union (according to a resolution adopted at the 14th General Assembly in 1970). Astronomy and Astrophysics Abstracts aims to present a comprehensive documentation of literature in all fields of astronomy and astrophysics. Every effort will be made to ensure that the average time interval between the date of receipt of the original literature and publication of the abstracts will not exceed eight months. This time interval is near to that achieved by monthly abstracting journals, com pared to which our system of accumulating abstracts for about six months offers the advantage of greater convenience for the user. Volume II contains literature published in 1974 and received before August IS, 1974; some older literature which was received late and which is not recorded in earlier volumes is also included. Begin ning with this volume some minor changes of our classification scheme have been made. We acknowledge with thanks contributions to this volume by Dr. J. BouSka, who surveyed journals and publications in the Czech language and supplied us with abstracts in English, and by the Common wealth Scientific and Industrial Research Organization (C.S.I.R.O.), Sydney, for providing titles and abstracts of papers on radio astronomy.

This book is about the social, political and cultural content of elementary and secondary textbooks in American education. It focuses on the nature of the discourses—the content and context—that represent what is included in textbooks.

This book is made up of two parts, the first devoted to general, historical and cultural background, and the second to the development of each subdiscipline that together comprise Chinese mathematics. The book is uniquely accessible, both as a topical reference work, and also as an overview that can be read and reread at many levels of sophistication by both sinologists and mathematicians alike.

A journey across centuries of religious conflict Toby Green’s incredible new book brings a vast panorama to life by focusing on the untold stories of individuals from all walks of life and every section of society who were affected by the Inquisition. From witches in Mexico, bigamists in Brazil, Freemasons, Hindus, Jews, Moslems and Protestants, the Inquisition reached every aspect of society. This history, though filled with stories of terror and the unspeakable ways in which human beings can treat one another, is ultimately one of hope, underscoring the resilience of the human spirit. Stretching from the unification of Spain under Ferdinand and Isabella in the fifteenth century to the Napoleanic wars, The Inquisition details this incredible history in all its richness and complexity.
