A tour of Mars in the human imagination, from ancient astrologers to modern explorers. Mars and its secrets have fascinated and mystified humans since ancient times. Due to its vivid color and visibility, its geologic kinship with Earth, and its potential as our best hope for settlement, Mars embodies everything that inspires us about space and exploration. For the Love of Mars surveys the red planet’s place in the human imagination, beginning with ancient astrologers and skywatchers and ending in our present moment of exploration and virtual engagement.   National Air and Space Museum curator Matthew Shindell describes how historical figures across eras and around the world have made sense of this mysterious planet. We meet Mayan astrologer priests who incorporated Mars into seasonal calendars and religious ceremonies; Babylonian astrologers who discerned bad omens; figures of the Scientific Revolution who struggled to comprehend it as a world; Victorian astronomers who sought signs of intelligent life; and twentieth- and twenty-first-century scientists who have established a technological presence on its surface. Along the way, we encounter writers and artists from each of these periods who take readers and viewers along on imagined journeys to Mars.   By focusing on the diverse human stories behind the telescopes and behind the robots we know and love, Shindell shows how Mars exploration has evolved in ways that have also expanded knowledge about other facets of the universe. Captained by an engaging and erudite expert, For the Love of Mars is a captivating voyage through time and space for anyone curious about Curiosity and the red planet.

Harold C. Urey (1893-1981) was one of the most famous American scientists of the twentieth century. Awarded the Nobel Prize in 1934 for his discovery of deuterium and heavy water, Urey later participated in the Manhattan Project and NASA's lunar exploration program. In this, the first ever biography of the chemist, Matthew Shindell shines new light on Urey's achievements and efforts to shape his public and private lives. Shindell follows Urey through his orthodox religious upbringing, the scientific work that won him the Nobel, and his subsequent efforts to use his fame to intervene in political, social, and scientific matters. At times, Urey succeeded, including when he helped create the fields of isotope geochemistry and cosmochemistry. But other endeavors, such as his promotion of world governance of atomic weapons, failed. By exploring those efforts, as well as Urey's evolution from farm boy to scientific celebrity, we can discern broader changes in the social and intellectual landscape of twentieth-century America. More than a life story, this book immerses readers in the struggles and triumphs of not only an extraordinary man, but also his extraordinary times.

How do scientists evaluate environmental knowledge for public policy? Discerning Experts examines three sets of landmark environmental assessments involving acid rain, ozone depletion, and sea level rise, exploring how experts judge scientific evidence and determine what the scientific facts are. The three case studies also explore how scientists come to agreement on contested issues, why consensus is considered important, and what factors contribute to confusion, bias, and error, and how scientists understand and navigate the boundaries between science and policy. The authors also suggest strategies for improving the assessment process. As the first study of the internal workings of large environmental assessments, this book explores the strengths and weaknesses of the assessment process and explains what it can—and cannot—be expected to contribute to public policy and the common good.
