Book Review

history of science. For all these one has to be a scientist whose interest goes beyond narrow boundaries of professional disciplines. Professor Arun Kumar Biswas has been able to write this beautiful book by virtue of his unique background. Over several decades now, the author has systematically specialized in several areas: applied chemistry, mineral engg., metallurgy, history of science and civilization as well as Ramkrishna and Vivekananda literature. He has degrees from University and MIT, USA. He was a Professor at IIT Kanpur for many years (1963 – 95) and after retirement held prestigious positions in Asiatic Society, Kolkata, Institute of Advanced Studies, Simla and to write extensively on history of science with special emphasis on ancient and medieval . His well acclaimed books and articles testify evidences from ancient texts, archeological evidences and information on available archeomaterials to establish ancient and medieval India’s achievements. In the book under review he examines a wider canvas based on his knowledge in two areas, namely, history of science in Europe and India and mineral sciences. The book critically reviews the birth and progress of Mineral Processing to Elemental Science in the mineral processing to modern chemistry during the three th th Medieval World: India and Europe, By : Arun momentous centuries ( 16 – 18 ) in medieval Europe.

The history of science, as Bernal had observed, is mostly taught and understood as a narration of various Chapter 1 of the monograph discusses, amongst other discoveries in sequence of time whereas it should really things why Agricola’s (1495-1555) monumental work De be studied and understood as history of relationship Re Metallica, published after his death, should be taken between science and society. This scholarly book does as the definitive starting point in the annals of not only this. It avoids chronological narration, it discusses, with the subject of mineral processing but also scientific references to mineral sciences and applied chemistry, how renaissance that initiated a dramatic review of Alchemy. and why particular issues need to be examined and how The author raises the important question as to why the findings were used to shape society and vice-versa. science of chemistry had a slow start when great advances Philosophy of science cannot be discussed by people where made by Galileo, Kepler, Newton, Boyle and so many who know only philosophy, magicians cannot talk about others in the fields of astronomy, mathematics and magic of science and ordinary historians would not know physics.

The author quotes from countries including excellent glass made in India. numerous texts to establish how detailed observations were recorded and analysed. There are quotations from the Chapter 6 reviews some other important texts, Vedas, Upanishads and other sources to show India’s particularly writings of Biriguceio who also wrote against achievements in various fields, specially iron and zinc, the alchemy calling it as ‘vain wish and childish folly’.
