The ?igveda is the first book of humankind and the most sacred scripture of Hinduism. It also happens to be the most ill-understood book of our times. Despite the extensive study by academic and religious scholars, the purpose and meaning of the ?igveda and many ancient Hindu scriptures remain unclear. In this pathbreaking book, the discovery of the ?igveda as a book of ancient cosmology is described, and related to the seals of ancient Indus Valley Civilization, thereby challenging our perception of humanity."The Vedas have always been lauded as containing the secrets of cosmogenesis. Raja Roy in his remarkable book shows how this is true not only from the yogic vison but according to the latest insights of modern physics. The book takes the reader on a vast panoramic journey through the universe of matter, mind and human history as well."David Frawley (Vamadeva Shastri), Director, American Institute of Vedic Studies"Roy presents a new framework for the understanding of the Vedic hymns from the point of view of physics and then he draws parallels with recent theories on the nature of the universe. We celebrate the new path he has hewn through the bush of old scholarship."Professor Subhash Kak, Oklahoma State University

To understand modern science as a coherent story, it is essential to recognize the accomplishments of the ancient Hindus. They invented our base-ten number system and zero that are now used globally, carefully mapped the sky and assigned motion to the Earth in their astronomy, developed a sophisticated system of medicine with its mind-body approach known as Ayurveda, mastered metallurgical methods of extraction and purification of metals, including the so-called Damascus blade and the Iron Pillar of New Delhi, and developed the science of self-improvement that is popularly known as yoga. Their scientific contributions made impact on noted scholars globally: Aristotle, Megasthenes, and Apollonius of Tyana among the Greeks; Al-Biruni, Al-Khwarizmi, Ibn Labban, and Al-Uqlidisi, Al-Ja?iz among the Islamic scholars; Fa-Hien, Hiuen Tsang, and I-tsing among the Chinese; and Leonardo Fibbonacci, Pope Sylvester II, Roger Bacon, Voltaire and Copernicus from Europe. In the modern era, thinkers and scientists as diverse as Ralph Waldo Emerson, Johann Wolfgang von Goethe, Johann Gottfried Herder, Carl Jung, Max Müller, Robert Oppenheimer, Erwin Schrödinger, Arthur Schopenhauer, and Henry David Thoreau have acknowledged their debt to ancient Hindu achievements in science, technology, and philosophy. The American Association for the Advancement of Science (AAAS), one of the largest scientific organizations in the world, in 2000, published a timeline of 100 most important scientific finding in history to celebrate the new millennium. There were only two mentions from the non-Western world: (1) invention of zero and (2) the Hindu and Mayan skywatchers astronomical observations for agricultural and religious purposes. Both findings involved the works of the ancient Hindus. The Ancient Hindu Science is well documented with remarkable objectivity, proper citations, and a substantial bibliography. It highlights the achievements of this remarkable civilization through painstaking research of historical and scientific sources. The style of writing is lucid and elegant, making the book easy to read. This book is the perfect text for all students and others interested in the developments of science throughout history and among the ancient Hindus, in particular.

The study of Mahabharata, the only surviving historical document, enables one to know about the scientific and cultural legacy of great India. This paper tries to unravel the scientific and technological advancement of India at the age of Mahabharata, i.e. 5000 years ago when Indian civilization was at its pinnacle. This study would help proper portrayal of India's past scientific achievements thereby recognition of India's contribution to the world civilization in science and technology.
