Godel's Proof.

1964119482London: Routledge and Kegan Paul Ltd 1964. Early printing of this work on Godel. Octavo original cloth. Near fine in a near fine dust jacket. From the library of physicist Stephen Hawking. Stephen Hawking was a theoretical physicist cosmologist and author who was director of research at the Centre for Theoretical Cosmology at the University of Cambridge at the time of his death. Hawking's scientific works included a collaboration with Roger Penrose on gravitational singularity theorems in the framework of general relativity and the theoretical prediction that black holes emit radiation often called Hawking radiation. He was the first to set out a theory of cosmology explained by a union of the general theory of relativity and quantum mechanics. Hawking may be one of the most recognizable of theoretical physicists in part due to ALS which gradually paralyzed him over the decades. After the loss of his speech he was able to communicate through a speech-generating device--initially through use of a handheld switch and eventually by using a single cheek muscle. He is also well known since he achieved commercial success with several works of popular science in which he discussed his theories and cosmology in general. His book A Brief History of Time appeared on the Sunday Times bestseller list for a record-breaking 237 weeks. The Universe in a Nutshell which many consider a sequel to A Brief History explains to a general audience various matters such as Godel's Incompleteness Theorem. Hawking also gave a sold-out lecture at Texas A&M University entitled "Godel and the End of Physics" in which he said "Godel's theorem ensured there would always be a job for mathematicians. I think M theory will do the same for physicists." This book was likely used in Hawking's research in writing The Universe in a Nutshell and his other writings on this topic. A wonderful association. In 1931 Kurt Godel published his fundamental paper "On Formally Undecidable Propositions of Principia Mathematica and Related Systems." This revolutionary paper challenged certain basic assumptions underlying much research in mathematics and logic. Godel received public recognition of his work in 1951 when he was awarded the first Albert Einstein Award for achievement in the natural sciences--perhaps the highest award of its kind in the United States. The award committee described his work in mathematical logic as "one of the greatest contributions to the sciences in recent times." However few mathematicians of the time were equipped to understand the young scholar's complex proof. Ernest Nagel and James Newman provide a readable and accessible explanation to both scholars and non-specialists of the main ideas and broad implications of Godel's discovery. It offers every educated person with a taste for logic and philosophy the chance to understand a previously difficult and inaccessible subject. Routledge and Kegan Paul Ltd hardcover books

John Quincy Adams: A Public Life A Private Life

19972311772New York: Alfred A. Knopf 1997. First Edition. Hard Cover. Good/Near Fine. First edition. Jacket near fine. Ink underlining and marginalia a few pages dog-eared. 1997 Hard Cover. We have more books available by this author!. xi 432 pp. "February 21 1848 the House of Representatives Washington D.C.: Congressman John Quincy Adams rising to speak suddenly collapses at his desk; two days later he dies in the Speaker's chamber. The public mourning that followed writes Paul C. Nagel "exceeded anything previously seen in America." Forgotten was his failed presidency and his often cold demeanor. It was the memory of an extraordinary human being--one who in his last years had fought heroically for the right of petition and against a war to expand slavery--that drew a grateful people to salute his coffin in the Capitol and to stand by the railroad tracks as his bier was transported from Washington to Boston. Nagel probes deeply into the psyche of this cantankerous misanthropic erudite hardworking son of a former president whose remarkable career spanned many offices: minister to Holland Russia and England U.S. senator secretary of state president of the United States 1825-1829 and finally U.S. representative the only ex-president to serve in the House. On the basis of a thorough study of Adams' seventy-year diary among a host of other documents the author gives us a richer account than we have yet had of JQA's life--his passionate marriage to Louisa Johnson his personal tragedies two sons lost to alcoholism his brilliant diplomacy his recurring depression his exasperating behavior--and shows us why in the end only Abraham Lincoln's death evoked a greater outpouring of national sorrow in nineteenth-century America. We come to see how much Adams disliked politics and hoped for more from life than high office; how he sought distinction in literary and scientific endeavors and drew his greatest pleasure from being a poet critic translator essayist botanist and professor of oratory at Harvard; how tension between the public and private Adams vexed his life; and how his frustrations kept him masked and aloof and unpopular. Nagel's great achievement in this first biography of America's sixth president in a quarter century is finally to portray Adams in all his talent and complexity. Alfred A. Knopf hardcover books
