In this eloquent, persuasive book, Neil Postman alerts us to the real and present dangers of this state of affairs, and offers compelling suggestions as to how to withstand the media onslaught. Before we hand over politics, education, religion, and journalism to the show business demands of the television age, we must recognize the ways in which the media shape our lives and the ways we can, in turn, shape them to serve out highest goals.

    Hazen writes of how the co-evolution of the geosphere and biosphere—of rocks and living matter—has shaped our planet into the only one of its kind in the Solar System, if not the entire cosmos.With an astrobiologist’s imagination, a historian’s perspective, and a naturalist’s passion for the ground beneath our feet, Hazen explains how changes on an atomic level translate into dramatic shifts in Earth’s makeup over its 4.567 billion year existence. He calls upon a flurry of recent discoveries to portray our planet’s many iterations in vivid detail. Through his theory of “co-evolution,” we learn how reactions between organic molecules and rock crystals may have generated Earth’s first organisms, which in turn are responsible for more than two-thirds of the mineral varieties on the planet.The Story of Earth is also the story of the pioneering men and women behind the sciences. Readers will meet black-market meteorite hawkers of the Sahara Desert, the gun-toting Feds who guarded the Apollo missions’ lunar dust, and the World War II Navy officer whose super-pressurized “bomb”—recycled from military hardware—first simulated the molten rock of Earth’s mantle. As a mentor to a new generation of scientists, Hazen introduces the intrepid young explorers whose dispatches from Earth’s harshest landscapes will revolutionize geology.

    He exposes the people and organizations that manipulate our perceptions and profit from our anxieties: politicians who win elections by heightening concerns about crime and drug use even as both are declining; advocacy groups that raise money by exaggerating the prevalence of particular diseases; TV news-magazines that monger a new scare every week to garner ratings.

    This was a military expedition into hostile territory'. In 1803 President Thomas Jefferson selected his personal secretary, Captain Meriwether Lewis, to lead a pioneering voyage across the Great Plains and into the Rockies. It was completely uncharted territory; a wild, vast land ruled by the Indians. Charismatic and brave, Lewis was the perfect choice and he experienced the savage North American continent before any other white man. UNDAUNTED COURAGE is the tale of a hero, but it is also a tragedy. Lewis may have received a hero's welcome on his return to Washington in 1806, but his discoveries did not match the president's fantasies of sweeping, fertile plains ripe for the taking. Feeling the expedition had been a failure, Lewis took to drink and piled up debts. Full of colourful characters - Jefferson, the president obsessed with conquering the west; William Clark, the rugged frontiersman; Sacagawea, the Indian girl who accompanied the expedition; Drouillard, the French-Indian hunter - this is one of the great adventure stories of all time and it shot to the top of the US bestseller charts. Drama, suspense, danger and diplomacy combine with romance and personal tragedy making UNDAUNTED COURAGE an outstanding work of scholarship and a thrilling adventure.
