Transported to the 21st century, Oppenheimer, Leo Szilard, and Enrico Fermi grapple with the legacy of the atom bomb in this “shattering and beautiful” time travel novel (Entertainment Weekly). Oh Pure and Radiant Heart plucks the three scientists who were key to the invention of the atom bomb—J. Robert Oppenheimer, Leo Szilard, and Enrico Fermi—as they watch history’s first mushroom cloud rise over the desert on July 16th, 1945 . . . and places them down in modern-day Santa Fe. One by one, the scientists are spotted by a shy librarian who becomes convinced of their authenticity. Entranced, bewildered, overwhelmed by their significance as historical markers on the one hand, and their peculiar personalities on the other, she, to the dismay of her husband, devotes herself to them. Soon the scientists acquire a sugar daddy—a young pothead millionaire from Tokyo who bankrolls them. Heroes to some, lunatics or con artists to others, the scientists finally become messianic religious figureheads to fanatics, who believe Oppenheimer to be the Second Coming. As the ever-growing convoy traverses the country in a fleet of RV’s on a pilgrimage to the UN, the scientists wrestle with the legacy of their invention and their growing celebrity, while Ann and her husband struggle with the strain on their marriage, a personal journey married to a history of thermonuclear weapons. “Possesses the nervy irreverence of Kurt Vonnegut and Joseph Heller . . . Can only be described as, well, genius.” —Vanity Fair
In Measuring Shadows, Raz Chen-Morris demonstrates that a close study of Kepler’s Optics is essential to understanding his astronomical work and his scientific epistemology. He explores Kepler’s radical break from scientific and epistemological traditions and shows how the seventeenth-century astronomer posited new ways to view scientific truth and knowledge. Chen-Morris reveals how Kepler’s ideas about the formation of images on the retina and the geometrics of the camera obscura, as well as his astronomical observations, advanced the argument that physical reality could only be described through artificially produced shadows, reflections, and refractions. Breaking from medieval and Renaissance traditions that insisted upon direct sensory perception, Kepler advocated for instruments as mediators between the eye and physical reality, and for mathematical language to describe motion. It was only through this kind of knowledge, he argued, that observation could produce certainty about the heavens. Not only was this conception of visibility crucial to advancing the early modern understanding of vision and the retina, but it affected how people during that period approached and understood the world around them.
