Paperback. Condizione: New. This introduction to the basic ideas of structural proof theory contains a thorough discussion and comparison of various types of formalization of first-order logic. Examples are given of several areas of application, namely: the metamathematics of pure first-order logic (intuitionistic as well as classical); the theory of logic programming; category theory; modal logic; linear logic; first-order arithmetic and second-order logic. In each case the aim is to illustrate the methods in relatively simple situations and then apply them elsewhere in much more complex settings. There are numerous exercises throughout the text. In general, the only prerequisite is a standard course in first-order logic, making the book ideal for graduate students and beginning researchers in mathematical logic, theoretical computer science and artificial intelligence. For the new edition, many sections have been rewritten to improve clarity, new sections have been added on cut elimination, and solutions to selected exercises have been included.…

1 Blatt Bahlsen-Briefpapier mit zweifarbigem Briefkopf, Design Martel Schwichtenberg. Rückseite mit Hintergrundillustration von Bahlsen-Bauten. Gestempelt "für H. Bahlsens-Keksfarbik K.-G." und Unterschrift. 29,5 x 21 cm * Obgleich Martel Schwichtenberg (1896-1945) - seit 1917 verantwortlich für das Corporate Design der Firma Bahlsen - bereits 1933 Deutschland verlassen hatte, blieb ihre vertragliche Beziehung mit Bahlsen in den 1930er und 1940er Jahren weiter bestehen. Das vorliegende Blatt zeigt den 1927 von Martel Schwichtenberg entworfenen neuen Schriftzug "Bahlsen", der auf die Unterschrift des Firmengründers Hermann Bahlsen zurückgeht - er wurde bis in die 1950er Jahre verwendet.…

Condizione: Good. 6 page group of correspondence. The main letter is typed on The Lovelace Foundation for Medical Education and Research letterhead. Dr. Schwichtenberg was Head of the Department of Aerospace Medicine & Bioastronautics. Mr. Nolan was the acting Director of Manned Flight at NASA. This sensitive letter was sent to his home address. There were two documents attached. Dr. Schwichtenberg suggested that after reading it, Mr. Nolan perhaps destroy it. This clearly did not happen! This is believed to be the only existing copies. Dr. Mayo worked at NASA for at least the period between 1958-65. His papers are at the Smithsonian and cover mainly space-related topics, generally revolving around human factors, as well as NASA activities and space program benefits. There was great concern over an article that appeared in January 1962 issue of Aerospace Journal by Mr. Walter Williams and Mr. Warren North which suggested astronaut selection criteria which were viewed by Dr. Schwichtenberg, Dr. Mayo, Chuck Roadman, and Mr. Nolan as wrongheaded and potentially dangerous. Dr. Schwichtenberg admonished Williams and North that "The burden of all this is that your requirements are out of line with the actually demonstrated requirements as pilots of spacecraft, and fail almost altogether to take into account the scientific requirements of the national space program. Aside from excessive education and flight time, your requirements as stated are somewhat more what the military services will require when their space efforts get under way rather than the purpose for which the NASA effort was intended." On April 9, 1959, at a press conference in Washington, Glennan (NASA ADMINISTRATOR) introduced to the public the seven men chosen to be this Nation's nominees for the first human voyagers into space. They were to be called "astronauts," as the pioneers of ballooning had been called "Argonauts," for they were to sail into a new, uncharted ocean. These personable pilots were introduced in civilian dress; many people in their audience forgot that they were volunteer test subjects and military officers. They were a contingent of mature Americans, average in build and visage, family men all, college-educated as engineers, possessing excellent health, and professionally committed to flying advanced aircraft. Compared with the average, white, middle-class American male, they enjoyed better health, physically and psychologically, and they had far more experience among and above the clouds. Slightly short of average in stature, they were above average in seriousness of purpose. Otherwise these seven seemed almost random samples of average American manhood. Yet the names of Carpenter, Cooper, Glenn, Grissom, Schirra, Shepard, and Slayton were perhaps to become as familiar in American history as those of any actor, soldier, or athlete. The astronauts were first and foremost test pilots, men accustomed to flying along in the newest, most advanced, and most powerful vehicles this civilization had produced. They were talented specialists who loved to fly high-performance aircraft and who had survived the natural selection process in their profession. The demand for excellence in piloting skills, in physical health, and psychological adaptability becomes ever more stringent as one ascends the ladder toward the elite among military aviators, those senior test pilots with upwards of 1500 hours' total flying time. Although the psycho physiological criteria for the selection of the best possible pilots for manned space flight had been under discussion for several years, the actual arrangement of the selection procedures for Mercury was directed by a NASA selection committee consisting of a senior management engineer, Donlan; a test pilot engineer, North; two flight surgeons, White and Augerson; two psychologists, Allen O. Gamble and Voas; and two psychiatrists, George E. Ruff and Edwin Z. Levy. These seven men had done the screening of records and the interviews and testing in Washington, constituting phases one and two of the selection program, before remanding their pool of 32 candidates to the medical examiners at the Lovelace Foundation. Back at Space Task Group headquarters at Langley, late in March 1959, phase five began. The final evaluation of data was made by correlating clinical and statistical information from New Mexico and Ohio. Eighteen of the 31 candidates came recommended without medical reservations for final consideration by Donlan and North. According to Donlan, although the physicians, psychiatrists, psychologists, and physiologists had done their best to establish gradations, the attrition rate was too low. So the final criteria for selecting the candidates reverted to the technical qualifications of the men and the technical requirements of the program, as judged by Donlan, North, White, and finally Gilruth. The selection tests, as it turned out, were largely tests of tests, "conducted as much for the research value in trying to formulate the characteristics of astronauts as for determining any deficiencies of the group being examined." The verbal responses at the interviews, before and after the psychophysiological testing, therefore, seem to have been as important final determinants as the candidates' test scores.
