SGN. The UPSC-Deputy Superintending Archaeologist Exam-History Subject Practice Sets eBook PDF Covers Objective Questions With Answers.

The application of chemistry within archaeology is an important and fascinating area. It allows the archaeologist to answer such questions as "what is this artefact made of?", "where did it come from?" and "how has it been changed through burial in the ground?", providing pointers to the earliest history of mankind. Archaeological Chemistry begins with a brief description of the goals and history of archaeological science, and the place of chemistry within it. It sets out the most widely used analytical techniques in archaeology and compares them in the light of relevant applications. The book includes an analysis of several specific archaeological investigations in which chemistry has been employed in tracing the origins of or in preserving artefacts. The choice of these investigations conforms to themes based on analytical techniques, and includes chapters on obsidian, ceramics, glass, metals and resins. Finally, it suggests a future role for chemical and biochemical applications in archaeology. Archaeological Chemistry enables scientists to tackle the fundamental issues of chemical change in the archaeological materials, in order to advance the study of the past. It will prove an essential companion to students in archaeological science and chemistry, field and museum archaeologists, and all those involved in conserving human artefacts.

Ramachandra Guha’s India after Gandhi is a magisterial account of the pains, struggles, humiliations and glories of the world’s largest and least likely democracy. A riveting chronicle of the often brutal conflicts that have rocked a giant nation, and of the extraordinary individuals and institutions who held it together, it established itself as a classic when it was first published in 2007. In the last decade, India has witnessed, among other things, two general elections; the fall of the Congress and the rise of Narendra Modi; a major anti-corruption movement; more violence against women, Dalits, and religious minorities; a wave of prosperity for some but the persistence of poverty for others; comparative peace in Nagaland but greater discontent in Kashmir than ever before. This tenth anniversary edition, updated and expanded, brings the narrative up to the present. Published to coincide with seventy years of the country’s independence, this definitive history of modern India is the work of one of the world’s finest scholars at the height of his powers.

Tantrasangraha, composed by the renowned Kerala astronomer Nīlakantha Somayājī (c.1444-1545 AD) ranks along with Āryabhatīya of Āryabhata and Siddhāntaśiromani of Bhāskarācārya as one of the major works which significantly influenced further work on astronomy in India. One of the distinguishing features is the introduction of a major revision of the traditional Indian planetary model. Nīlakantha arrived at a unified theory of planetary latitudes and a better formulation of the equation of centre for the interior planets (Mercury and Venus) than was previously available. In preparing the translation and explanatory notes, K. Ramasubramanian and M. S. Sriram have used authentic Sanskrit editions of Tantrasangraha by Surand Kunjan Pillai and K V Sarma. All verses have been translated into English, which have been supplemented with detailed explanations including all necessary mathematical relations, illustrative examples, figures and tables using modern mathematical notation.
