PDF-(EBOOK)-The Perfect Machine: Building the Palomar Telescope

Almost a halfcentury after is completion the 200inch Palomar telescope remains an unparalleled combination of vast scale and microscope detail As huge as the Pantheon of Rome and as heavy as the Statue of Liberty this magnificent instrument is so precisely built that its seventeenfoot mirror was handpolished to a tolerance of 21000000 of an inch The telescopes construction drove some to the brink of madness made others fearful that mortals might glimpse heaven and transfixed an entire nation Ronald Florence weaves into his account of the creation of the perfect machine a stirring chronicle of the birth of Big Science and a poignant rendering of an America mired in the depression yet reaching for the stars.

Michael Hanlon says the photos "illustrate that our universe is not only deeply strange, but also almost impossibly beautiful."  . From newborn galaxies to icy worlds and blazing quasars, a behind-the-scenes story of how Palomar Observatory astronomers unveiled our complex universe.Ever since 1936, pioneering scientists at Palomar Observatory in Southern California have pushed against the boundaries of the known universe, making a series of dazzling discoveries that changed our view of the cosmos: quasars, colliding galaxies, supermassive black holes, brown dwarfs, supernovae, dark matter, the never-ending expansion of the universe, and much more. In Cosmic Odyssey, astronomer Linda Schweizer tells the story of the men and women at Palomar and their efforts to decipher the vast energies and mysterious processes that govern our universe.Palomar was the Apollo mission of its era. The first images from the 200-inch George Ellery Hale telescope, commissioned in 1948 as the world\'s largest, generated as much excitement as images from the moon in 1969 and from the Hubble Space Telescope more recently. So far, Palomar\'s Big Eye and three other telescopes have yielded more than 75,000 telescope-nights of precious data. Schweizer takes readers behind the scenes of scientific discovery, mapping the often chaotic process of detours, dead ends, and serendipitous leaps of insight. Although her focus is on Palomar, she follows threads of discovery across the world to other teams and observatories. Based on more than one hundred interviews and enhanced by research in scientific journals, her account paints a fascinating picture of how discrete insights acquired over decades by researchers in a global community cascade, collide, and finally coalesce into the discoveries we come to accept as facts.
