From Space to Earth tracks the evolution of the technology of photovoltaics, the use of solar cells to convert the sun's energy into electricity. John Perlin's painstaking research results in a fascinating account of the development of this technology, from its shaky nineteenth-century beginnings mired in scientific controversy to its high-visibility success in the space program, to its current position as a versatile and promising power source.

Electric currents are fundamental to the structure and dynamics of space plasmas, including our own near-Earth space environment, or “geospace.”This volume takes an integrated approach to the subject of electric currents by incorporating their phenomenology and physics for many regions in one volume. It covers a broad range of topics from the pioneers of electric currents in outer space, to measurement and analysis techniques, and the many types of electric currents. First volume on electric currents in space in over a decade that provides authoritative up-to-date insight on the current status of research Reviews recent advances in observations, simulation, and theory of electric currents Provides comparative overviews of electric currents in the space environments of different astronomical bodies Electric Currents in Geospace and Beyond serves as an excellent reference volume for a broad community of space scientists, astronomers, and astrophysicists who are studying space plasmas in the solar system.

NEW YORK TIMES BOOK REVIEW EDITORS’ CHOICE • An outsider who can travel between worlds discovers a secret that threatens the very fabric of the multiverse in this stunning debut, a powerful examination of identity, privilege, and belonging. WINNER OF THE COMPTON CROOK AWARD • FINALIST FOR THE LOCUS AWARD • “Gorgeous writing, mind-bending world-building, razor-sharp social commentary, and a main character who demands your attention—and your allegiance.”—Rob Hart, author of The Warehouse ONE OF THE BEST BOOKS OF THE YEAR—NPR, Library Journal, Book Riot Multiverse travel is finally possible, but there’s just one catch: No one can visit a world where their counterpart is still alive. Enter Cara, whose parallel selves happen to be exceptionally good at dying—from disease, turf wars, or vendettas they couldn’t outrun. Cara’s life has been cut short on 372 worlds in total. On this dystopian Earth, however, Cara has survived. Identified as an outlier and therefore a perfect candidate for multiverse travel, Cara is plucked from the dirt of the wastelands. Now what once made her marginalized has finally become an unexpected source of power. She has a nice apartment on the lower levels of the wealthy and walled-off Wiley City. She works—and shamelessly flirts—with her enticing yet aloof handler, Dell, as the two women collect off-world data for the Eldridge Institute. She even occasionally leaves the city to visit her family in the wastes, though she struggles to feel at home in either place. So long as she can keep her head down and avoid trouble, Cara is on a sure path to citizenship and security. But trouble finds Cara when one of her eight remaining doppelgängers dies under mysterious circumstances, plunging her into a new world with an old secret. What she discovers will connect her past and her future in ways she could have never imagined—and reveal her own role in a plot that endangers not just her world but the entire multiverse. “Clever characters, surprise twists, plenty of action, and a plot that highlights social and racial inequities in astute prose.”—Library Journal (starred review)
