第147页 - The story used to be told about him in Princeton that while he was indeed a demigod he had made a detailed study of humans and could imitate them perfectly. Actually he had great social presence, a very warm, human personality, and a wonderful sense of humor. These qualities, together with his incredible mental capacity, made him a superb teacher.?
第23页 - Preliminary discussion of the logical design of an electronic computing instrument," by AW Burks, HH Goldstein, and J. von Neumann, was written 15 years before the term was coined. We find it fascinating to compare the design therein with all computers produced to date. It is a tribute to von Neumann's genius that this design, originally intended to solve nonlinear differential equations...?
第35页 - Mauchly, working at the Moore School of Electrical Engineering of the University of Pennsylvania, then began formulating his own ideas on how a general-purpose computer might be built.?
第139页 - A research physicist at the National Bureau of Standards (now the National Institute of Standards and Technology) from 1951-1969, he was its director from 1 969- 1 972.?
第26页 - College and joined the staff of the Moore School of Electrical Engineering at the University of Pennsylvania.?
第39页 - Computer), which was first demonstrated at the Moore School of Electrical Engineering at the University of Pennsylvania at Philadelphia Feb 14, 1946.?
第145页 - ... we should realize that the proposed machine turned out to contain over 17,000 tubes of 16 different types operating at a fundamental clock rate of 100,000 pulses per second. . . . once every 10 microseconds an error would occur if a single one of the 17,000 tubes operated incorrectly; this means that in a single second there were 1.7 billion . . . chances of a failure occurring . . . Man had never made an instrument capable of operating with this degree of fidelity or reliability, and this is...?
第146页 - ENIAC contract that the university "in cooperation with and under the direction of representatives of the Ballistic Research Laboratory . . . shall engage in research and experimental work in connection with the development of an electronic numerical integrator and computer. . . ." The university agreed to furnish copies of reports and in the event "the contract results in the fabrication and completion of any part or unit . . . [it] shall be delivered to the Government. . . ." At the beginning,...?
第145页 - Goldstine later explained the risks associated with attempting the proposed electronic calculator project: 8 ... we should realize that the proposed machine turned out to contain over 17,000 tubes of 16 different types operating at a fundamental clock rate of 100,000 pulses per second. . . . once every 10 microseconds an error would occur if a single one of the 17,000 tubes operated incorrectly; this means that in a single second there were 1.7 billion . . . chances of a failure occurring...?
第145页 - ... which can readily be put in the form of iterative equations. Purely mechanical calculating devices can be devised to expedite the work. However, a great gain in the speed of the calculation can be obtained if the devices which are used employ electronic means for the performance of the calculation, because the speed of such devices can be made very much higher than that of any mechanical device.?
