The authors trace the formation and breakup of the planets,asteroids, and comets where meteorites originated, their longjourney through space, their fall to Earth, their recovery, andwhat scientists are learning from them. The book contains a greatdeal of material about the “84001 Martian meteorite,” which hasraised provocative new questions about life on the red planet.Looking forward, the authors chart the exciting new era ofplanetary, asteroidal, and cometary exploration planned for thiscentury.

A dazzling journey across the sciences and humanities in searchof deep laws to unite them. -- The Wall Street Journal One of our greatest living scientists--and the winner of twoPulitzer Prizes for On Human Nature and TheAnts --gives us a work of visionary importance that may be thecrowning achievement of his career. In Consilience (a wordthat originally meant "jumping together"), Edward O. Wilson renewsthe Enlightenment's search for a unified theory of knowledge indisciplines that range from physics to biology, the social sciencesand the humanities. Using the natural sciences as his model, Wilson forges dramaticlinks between fields. He explores the chemistry of the mind and thegenetic bases of culture. He postulates the biological principlesunderlying works of art from cave-drawings to Lolita. Presentingthe latest findings in prose of wonderful clarity and oratoricaleloquence, and synthesizing it into a dazzling whole, Consilience is science in the path-clearing traditions ofNewton, Einstein, and R

Thinking about moving to mars? Well, why not? Mars, after all,is the planet that holds the greatest promise for humancolonization. But why speculate about the possibilities when youcan get the real scientific scoop from someone who's been happilyliving and working there for years? Straight from thenot-so-distant future, this intrepid pioneer's tips for physical,financial, and social survival on the Red Planet cover: - How toget to Mars (Cycling spacecraft offer cheap rides, but the smell isnot for everyone.)- Choosing a spacesuit (The old-fashioned butreliable pneumatic Neil Armstrong style versus the sleek new--butanatomically unforgiving--elastic "skinsuit.")- Selecting a habitat(Just like on Earth: location, location, location.)- Finding a jobthat pays well and doesn't kill you (This is not a metaphor onMars.)- How to meet the opposite sex (Master more than fortyMars-centric pickup lines.) With more than twenty originalillustrations by Michael Carroll, Robert Murray, and other renownedspace artists,

For everyone who has looked up at the stars on a clear nightand longed to know more about them, here is the perfectintroduction and guide to discovering the stars. Discover the Stars leads you on a tour of all the stars andconstellations visible with the naked eye and introduces you todeep-sky objects that can be seen with binoculars or a simpletelescope. The tour is conducted by the editor of Astronomymagazine, Richard Berry, whose two-color, computer-plotted sky mapsand clear instructions make stargazing fun and productive from yourfirst night out. The heart of Discover the Stars is two sections of big, beautifulsky maps and charts. The first section features twelve maps thatshow the entire sky overhead as it appears during each month of theyear. These outline all the constellations visible anywhere in theNorthern Hemisphere, and the accompanying text reveals the richancient mythology that surrounds the star groups. The second section is made up of twenty-three star ch

There has been an explosive growth in the field ofcombinatorial algorithms. These algorithms depend not only onresults in combinatorics and especially in graph theory, but alsoon the development of new data structures and new techniques foranalyzing algorithms. Four classical problems in networkoptimization are covered in detail, including a development of thedata structures they use and an analysis of their running time.Data Structures and Network Algorithms attempts to provide thereader with both a practical understanding of the algorithms,described to facilitate their easy implementation, and anappreciation of the depth and beauty of the field of graphalgorithms.

Anthrax. Smallpox. Incurable and horrifying Ebola-relatedfevers. For two decades, while a fearful world prepared for nuclearwinter, an elite team of Russian bioweaponeers began to till a newkilling field: a bleak tract sown with powerful seeds of massdestruction--by doctors who had committed themselves to creating abiological Armageddon. Biohazard is the never-before-told story ofRussia's darkest, deadliest, and most closely guarded Cold Warsecret. No one knows more about Russia's astounding experiments withbiowarfare than Ken Alibek. Now the mastermind behind Russia's germwarfare effort reveals two decades of shocking breakthroughs...howMoscow's leading scientists actually reengineered hazardousmicrobes to make them even more virulent...the secrets behind thediscovery of an invisible, untraceable new class of biologicalagents just right for use in political assassinations...thestartling story behind Russia's attempt to turn a sample of theAIDS virus into the ultimate bioweapon.
