Biography Climbing Julian Mountain Schwinger Scientific

In the 1930s, physics was in a crisis. There appeared to be no way to reconcile the new theory of quantum mechanics with Einstein's theory of relativity. Several approaches had been tried and had failed. In the post-World War II period, four eminent physicists rose to the challenge and developed a calculable version of quantum electrodynamics (QED), probably the most successful theory in physics. This formulation of QED was pioneered by Freeman Dyson, Richard Feynman, Julian Schwinger, and Sin-Itiro Tomonaga, three of whom won the Nobel Prize for their work. In this book, physicist and historian Silvan Schweber tells the story of these four physicists, blending discussions of their scientific work with fascinating biographical sketches. Setting the achievements of these four men in context, Schweber begins with an account of the early work done by physicists such as Dirac and Jordan, and describes the gathering of eminent theorists at Shelter Island in 1947, the meeting that heralded the new era of QED. The rest of his narrative comprises individual biographies of the four physicists, discussions of their major contributions, and the story of the scientific community in which they worked. Throughout, Schweber draws on his technical expertise to offer a lively and lucid explanation of how this theory was finally established as the appropriate way to describe the atomic and subatomic realms.

When mountain climber Simon Yates cut the rope and sent his friend and climbing partner Joe Simpson plummeting to an ordeal few mountaineers can have contemplated, the outcome was totally unpredictable. That Simpson survived his experience on Peru's Siula Grande is a revelation of the power of the human spirit to overcome fear, pain and deprivation of almost unimaginable intensity. He did not expect to live it all over again - more than once. The first test was to write his award-winning account of the ordeal in Touching the Void. That meant dragging the terrifying experience out of the deeper shadows of his memory. Next, another fall in the Himalaya crippled and almost broke him. He felt forced to test his nerve again, and struggled on crutches to 20,000 feet on Pumori, near Everest. On his descent he heard that a young, first-time climber had been killed by a chance rockfall. What sense could he make now of this game of ghosts that had claimed the lives of so many of his friends over the years he had been climbing, while he had survived so many events that should have meant certain death? In an attempt to find catharsis for his confused emotions he wrote this e xtraordinary memoir, revealing his early ife and his fifteen years of climbing on three continents, before and after the life-changing experience of Siula Grande. His gripping story recounts, with total honesty, experiences that range from hilarious to poignant to nearly unbelievable. Here are the signposts that have directed him since childhood to measure fear and embrace the unknown. He wonders about the luck or the choices along the way that have caused the loss of so many climbing friends: "Ghosts everywhere I look, all Isee are ghosts - or perhaps I am the ghost, a spectre of my past, standing in the rubble of my present, anxiously awaiting the future". This is a compelling work of adventure and introspection that will hold both moutaineers and armchair travelers spellbound.

Julian Schwinger - Julian Seymour Schwinger (February 12, 1918 -- July 16, 1994) was an American theoretical physicist. He formulated the theory of renormalization and posited a phenomenon of electron-positron pairs known as the Schwinger effect.

Cannon Mountain (New Hampshire) - Cannon Mountain (formerly Profile Mountain) is a 4,186 foot (1,276 meter) peak in the White Mountains of New Hampshire. Known for both its technical rock climbing (particularly on Cannon Cliff, pictured) and its skiing (it is a state owned ski area), the mountain was home to the Old Man of the Mountain until its collapse on May 3, 2003.

THU Wei-Mei Climbing Wall - The Wei-Mei Climbing Wall completed in 2004, in memory of Wei-Mei Lin, who was the leader of Mountaing Climbing Club, died in mountain accident in 2001. She devoted herself to establish a climbing wall for students at Tunghai University.
