In college, I ran against Kenyans, and wondered whether endurance genes might have traveled with them from East Africa. At the same time, I began to notice that a training group on my team could consist of five men who run next to one another, stride for stride, day after day, and nonetheless turn out five entirely different runners. How could this be?We all knew a star athlete in high school. The one who made it look so easy. He was the starting quarterback and shortstop; she was the all-state point guard and high-jumper. Naturals. Or were they?The debate is as old as physical competition. Are stars like Usain Bolt, Michael Phelps, and Serena Williams genetic freaks put on Earth to dominate their respective sports? Or are they simply normal people who overcame their biological limits through sheer force of will and obsessive training?The truth is far messier than a simple dichotomy between nature and nurture. In the decade since the sequencing of the human genome, researchers have slowly begun to uncover how the relationship between biological endowments and a competitor’s training environment affects athleticism. Sports scientists have gradually entered the era of modern genetic research.In this controversial and engaging exploration of athletic success, Sports Illustrated senior writer David Epstein tackles the great nature vs. nurture debate and traces how far science has come in solving this great riddle. He investigates the so-called 10,000-hour rule to uncover whether rigorous and consistent practice from a young age is the only route to athletic excellence.Along the way, Epstein dispels many of our perceptions about why top athletes excel. He shows why some skills that we assume are innate, like the bullet-fast reactions of a baseball or cricket batter, are not, and why other characteristics that we assume are entirely voluntary, like an athlete’s will to train, might in fact have important genetic components.This subject necessarily involves digging deep into sensitive topics like race and gender. Epstein explores controversial questions such as:Are black athletes genetically predetermined to dominate both sprinting and distance running, and are their abilities influenced by Africa’s geography?Are there genetic reasons to separate male and female athletes in competition?Should we test the genes of young children to determine if they are destined for stardom?Can genetic testing determine who is at risk of injury, brain damage, or even death on the field?Through on-the-ground reporting from below the equator and above the Arctic Circle, revealing conversations with leading scientists and Olympic champions, and interviews with athletes who have rare genetic mutations or physical traits, Epstein forces us to rethink the very nature of athleticism.

    Drawing on a wide range of classic and recent studies in anthropology and sociology, Eriksen examines the relationship between ethnicity, class, gender and nationhood, as well as current issues of racism, globalisation and multiculturalism. Influential theories are presented and critically compared in a lucid and comprehensive manner. A core text for all students of social anthropology and related subjects, Ethnicity and Nationalism has been a leading introduction to the field since its original publication in 1993. This new edition - expanded and thoroughly revised - is indispensable to anyone seriously interested in understanding ethnic phenomena. New chapters cover recent studies of migration, cultural creolisation, racism, gender and nationalism, and the dilemmas of multiculturalism.

    Where did everything else come from? Supernovas, the huge unstable suns whose immense convulsions and titanic explosions are the largest and most shattering events in the universe. Untold trillions of these giant crucibles in space, erupting down the long reaches of time, are now known to have forged all the heavier elements that in turn formed the metals, the rocks, and--at least once--life itself. Did earlier civilizations watch in wonder at the flash of distant supernovas? What about the 1987 "next-door" supernova? Have supernovas ever threatened life on Earth? Will they in years to come? Offering a compelling view of supernovas and the new understanding about the evolution of the universe, Isaac Asimov's The Exploding Suns is one of the most breathtaking science books ever to address these and many other questions.

    This short treatise on Renaissance statecraft and power has been controversial and inspiring since its first publication nearly 500 years ago. Machiavellis analysis of the ways men seize, retain, and lose power represented the first expose of realpolitik and it has been used ever since as a handbook for manipulating events to one?s own advantage. Here, Machiavellis text is interpreted for the modern day world of business. Tim Phillipss interpretation of Machiavellis work is not a substitute for the original its purpose is simply to illustrate the timeless nature of Machiavellis insights by bringing them to life through modern business and political case studies. This brilliant interpretation of The Prince Is an entertaining accompaniment to one of the most famous books ever written.

    In the intervening years, the country has experienced a bitter war with Iraq, the transformation of society under the clergy and, more recently, the expansion of the state and the struggle for power between the old elites, the intelligentsia and the commercial middle class. The author is a compassionate expositor. While he adroitly negotiates the twists and turns of the country's regional and international politics, at the heart of his book are the people of Iran. It is to them and their resilience that this book is dedicated, as Iran emerges at the beginning of the twenty-first century as one of the most powerful states in the Middle East.

    They may also contaminate evidence, or not know what to look for in crime scenes that typically are far more chaotic and confusing, whether inside or outside, than on TV.   Forensic experts will tell you that the most important person entering a scene is the very first responding officer - the chain of evidence starts with this officer and holds or breaks according to what gets stepped on, or over, collected or contaminated, looked past, or looked over, from every person who enters or interprets the scene, all the way through the crime lab and trial.  And forensic experts will tell you the success of a case can depend on any one expert's knowledge of quirky things, such as:"The Rule of the First Victim": (the first victim of a criminal usually lives near the criminal's home) Criminals' snacking habits at the scene"Nature's Evidence Technicians," the birds and rodents that hide bits of bone, jewelry, and fabric in their nestsThe botanical evidence found in criminals' pants cuffs Baseball caps as prime DNA repositoriesThe tales told by the application of physics to falling blood drops.      Forensic experts talk about their expertise and their cases here.  They also talk about themselves, their reactions to the horrors they witness, and their love of the work.  For example, a DNA analyst talks about how she drives her family crazy by buccal-swabbing them all at Thanksgiving dinner.  A latent print examiner talks about how he examines cubes of Jell-O at any buffet he goes to for tell-tale prints.  A crime scene investigator gives his tips on clearing a scene of cops: he slaps "Bio-hazard" and "Cancer Causing Agent" stickers on his equipment.  And an evidence technician talks about how hard it is to go to sleep after processing a scene, re-living what you've just witnessed, your mind going a hundred miles an hour.   This is a world that TV crime shows can't touch.  Here are eighty experts - including beat cops, evidence technicians, detectives, forensic anthropologists, blood spatter experts, DNA analysts, latent print examiners, firearms experts, trace analysts, crime lab directors, and prosecution and defense attorneys - speaking in their own words about what they've seen and what they've learned to journalist Connie Fletcher, who has gotten cops to talk freely in her bestsellers What Cops Know,  Pure Cop, and Breaking and Entering.   Every Contact Leaves A Trace presents the science, the human drama, and even the black comedy of crime scene investigation.   Let the experts take you into their world. This is their book - their words, their knowledge, their stories.  Through it all, one Sherlock Holmesian premise unites what they do and what it does to them: Every contact leaves a trace.

    Planetary science has mainly been a descriptive science, but it is becoming increasingly experimental. The space probes that went up between the 1960s and 1990s were primarily generalists-they collected massive amounts of information so that scientists could learn what questions to pursue. But recent missions have become more focused: Scientists know better what information they want and how to collect it. Even now probes are on their way to Mercury, Venus, Mars, and Pluto, with Europa-one of Jupiter's moons-on the agenda. In a sweeping look into the manifold objects inhabiting the depths of space, Lives of the Planets delves into the mythology and the knowledge humanity has built over the ages. Placing our current understanding in historical context, Richard Corfield explores the seismic shifts in planetary astronomy and probes why we must change our perspective of our place in the universe. In our era of extraordinary discovery, this is the first comprehensive survey of this new understanding and the history of how we got here.
