In addition to fieldwork and traditional methods, paleoanthropologists and archaeologists now draw upon genetics and other cutting-edge scientific techniques. In fifty chapters, Prehistoric Investigations tells the story of the many thought-provoking discoveries that have transformed our understanding of the distant past.

    He set about subduing every kingdom possible including those of his brothers. The only person to oppose his arrogance was his half-brother, Bahubali, who defeated Bharata in single combat. However, Bahubali abdicated all claims to the throne and left for the forests to meditate. Centuries later Chavundaraya, a commander-in-chief of the Ganga dynasty built a 57 feet high statue of Bahubali at Shravana Belagola. This story has been taken from Pampa's Adi Purana and Panchabana's Bhujabali Charita.

    In this Very Short Introduction, Peter M. Higgins, a renowned popular-science writer, unravels the world of numbers, demonstrating its richness and providing an overview of all the number types that feature in modern science and mathematics. Indeed, Higgins paints a crystal-clear picture of the number world, showing how the modern number system matured over many centuries, and introducing key concepts such as integers, fractions, real and imaginary numbers, and complex numbers. Higgins sheds light on such fascinating topics as the series of primes, describing how primes are now used to encrypt confidential data on the internet. He also explores the infinite nature of number collections and explains how the so-called real numbers knit together to form the continuum of the number line. Written in the fashion of Higgins' highly popular science paperbacks, Numbers accurately explains the nature of numbers and how so-called complex numbers and number systems are used in calculations that arise in real problems.

    Putting people into places and situations unprecedented in history is stirred the imagination while the human experience was expanding and redefining. Yet, space exploration compels humans to confront a hostile environment of cosmic radiations, radical changes in the gravity and magnetic fields, as well as social isolation. Therefore, any space traveller is submitted to relevant health-related threats. In the twenty-first century, human space flight is poised to continue, but it will enjoy the ongoing developments in science and technology. It will become more networked, more global, and more oriented toward primary goals. A novel international human space flight policy could help achieve these objectives by clarifying the rationale, the ethics of acceptable risk, the role of remote presence, and the need for balance between funding and ambition to justify the risk of human lives. In order to address such a challenge, a preliminary careful survey of the available scientific data is mandatory to set forth adequate countermeasures. Envisaged solutions should provide a sound and technically feasible approach for counteracting microgravity and cosmic rays effects, which represent the main health risk for space crews. This objective must necessarily be sustained by national/international space agencies, which would coordinate their common efforts into a defined international spaceflight program.

    The Perfection Point is ideal for sports fans interested in the scientific basis of athletic excellence and a fascinating read for science fans interested in the physics of sports.

    But there were restrictions too, that come with growing up in an orthodox Tamil Brahmin family, as well as the rarely spoken about dangers of predatory male relatives. Ruskin College, Oxford, gave her her first taste of freedom in 1955, at the age of 22. Oxford brought her a degree in philosophy and economics—as well as hardship, as she washed dishes in a cafe to pay her fees. It was here, too, that she had her early encounters with the sensual life. With rare candour, she writes of her romantic liaisons in Oxford and Harvard, and falling in love with her ‘unsuitable boy’—her husband, Lakshmi Jain, whom she married against her beloved father’s wishes.Devaki’s professional life saw her becoming deeply involved with the cause of ‘poor’ women—workers in the informal economy, for whom she strove to get a better deal. In the international arena, she joined cause with the concerns of the colonized nations of the south, as they fought to make their voices heard against the rich and powerful nations of the former colonizers. Her work brought her into contact with world leaders and thinkers, amongst them, Vinoba Bhave, Nelson Mandela, Desmond Tutu, Henry Kissinger, Amartya Sen, Doris Lessing and Iris Murdoch, her tutor at St Anne’s College, Oxford, who became a lifelong friend.In all these encounters and anecdotes, what shines through is Devaki Jain’s honesty in telling it like it was—with a message for women across generations, that one can experience the good, the bad and the ugly, and remain standing to tell the story.

    Abdul Kalam, our most distinguished scientist, and close associate Y.S. Rajan examine India's strengths—and weaknesses—to offer a vision of how India can be among the world's first five economic powers in the year 2020. They cite growth rates and develoent trends to show that the goal is not an unrealistic one. Past successes, too, bear them out. For example, we were able to launch the green revolution at a time when experts had all but given up on India ever becoming self-sufficient in food. Similarly, in the field of space technology we started from scratch to have today a system of satellite-based communication linking remote regions of the country. The same sense of purpose can lead us to success in many other areas crucial to achieving the goal of a prosperous, strong nation, assert Kalam and Rajan.

    We start counting our fingers and toes and end up balancing checkbooks and calculating risk. So powerful is the appeal of numbers that many people ascribe to them a mystical significance. Other numbers go beyond the supernatural, working to explain our universe and how it behaves. In Cosmic Numbers, mathematics professor James D. Stein traces the discovery, evolution, and interrelationships of the numbers that define our world. Everyone knows about the speed of light and absolute zero, but numbers like Boltzmann’s constant and the Chandrasekhar limit are not as well known, and they do far more than one might imagine: They tell us how this world began and what the future holds. Much more than a gee-whiz collection of facts and figures, Cosmic Numbers illuminates why particular numbers are so important—both to the scientist and to the rest of us.

    Approaching science with a freshness unbound by convention or previous expectations, he produced some of the most original scientific thinking of the nineteenth century - and his discoveries went on to shape the twentieth century.

    However, recent discoveries of astonishing accomplishments from the Neolithic Age - in art, technology, writing, math, science, religion, medicine and exploration - demand a fundamental rethinking of humanity before the dawn of written history.In this fascinating book, Richard Rudgley describes how:* The intrepid explorers of the Stone Age discovered all of the world's major land masses long before the so-called Age of Discovery* Stone Age man performed medical operations, including amputations and delicate cranial surgeries* Paleolithic cave artists of Western Europe used techniques that were forgotten until the Renaissance* Prehistoric life expectancy was better than it is for contemporary third-world populationsRudgley reminds us just how savage so-called civilized people can be, and demonstrates how the cultures that have been reviled as savage were truly civilized. The Lost Civilizations of the Stone Age shows the great debt that contemporary society owes to its prehistoric predecessors. It is a rich introduction to a lost world that will redefine the meaning of civilization itself.

    Students, researchers, historians, specialists — in short, everyone with an interest in mathematics — will find it engrossing and stimulating.Beginning with the ancient Near East, the author traces the ideas and techniques developed in Egypt, Babylonia, China, and Arabia, looking into such manuscripts as the Egyptian Papyrus Rhind, the Ten Classics of China, and the Siddhantas of India. He considers Greek and Roman developments from their beginnings in Ionian rationalism to the fall of Constantinople; covers medieval European ideas and Renaissance trends; analyzes 17th- and 18th-century contributions; and offers an illuminating exposition of 19th century concepts. Every important figure in mathematical history is dealt with — Euclid, Archimedes, Diophantus, Omar Khayyam, Boethius, Fermat, Pascal, Newton, Leibniz, Fourier, Gauss, Riemann, Cantor, and many others.For this latest edition, Dr. Struik has both revised and updated the existing text, and also added a new chapter on the mathematics of the first half of the 20th century. Concise coverage is given to set theory, the influence of relativity and quantum theory, tensor calculus, the Lebesgue integral, the calculus of variations, and other important ideas and concepts. The book concludes with the beginnings of the computer era and the seminal work of von Neumann, Turing, Wiener, and others."The author's ability as a first-class historian as well as an able mathematician has enabled him to produce a work which is unquestionably one of the best." — Nature Magazine.

    Essentially, you make an initial guess, and then get more data to improve it. Bayes Theorem, or Bayes Rule, has a ton of real world applications, from estimating your risk of a heart attack to making recommendations on Netflix But It Isn't That Complicated This book is a short introduction to Bayes Theorem.

The examples are intentionally kept simple to focus solely on Bayes Theorem without requiring that the reader know complicated probability distributions. If you want to learn the basics of Bayes Theorem as quickly as possible, with some easy to duplicate examples, this is a good book for you.

    Of the wider issue of global politics, he reasons, the rise of Islamic fundamentalism has been a side effect. And religious intolerance places the minority communities of the country in a precarious position.They have to come to terms with a rapidly changing situation. A White Trail is an ethnographic study of these communities and the changes they are having to face. At a time when almost all accounts of religious minorities in the country focus on the persecution and discrimination they experience, A White Trail delves deeper into their lives, using the occasion of religious festivals to gain a deeper insight into the psyche of Pakistani Hindus, Sikhs, Christians, Zoroastrians and Bahais. It seeks to understand, through the oral testimonies of the members of these communities, larger socio-political issues arising from the situation.A White Trail originally began as a series of newspaper articles written by Lahore - based Haroon Khalid for Pakistans widely - circulated weekly, The Friday Times.

    Lying and killing for the sake of peace and order, Indra felt he was unworthy of being king of heaven. A new king was installed on his throne! Now it was up to Indra’s wife Shachi to ensure that his honour survived. Would the gods ever regain their respect for her beloved?
