Softcover. Zustand: very good. Time-Lag in a Control System: "It often happens in physical experiments and in technical processes that there is some physical quantity, subject to random disturbances, which it is required to keep as nearly constant as possible by the operation of some controlling gear. For example, it may be required to keep a room, or a reaction vessel, at a constant temperature by controlling the electric current passing through a heating coil, or steam passing through heating pipes, or the operation of a heating or cooling engine. The operation of the controlling gear could be by trial and error, but it may often be desirable that it shall be made to depend in some definite way on the behaviour of the physical quantity to be controlled (controlling gear); and the apparatus employed (control apparatus). The two together comprise the Control System." No. 756. Volume 235. pp. 415-444. Co-authored by: A. Callender of the Research Department, I.C.I (Alkali) Limited, D.R. Hartree, F.R.S. and A.

Hardcover. Zustand: Very Good. 1st Edition. 8vo; pp. xiii, 528; Hartree pp. 342-364 [whole volume offered]. A MECCANO DIFFERENTIAL ANALYZER. Hartree's important account of the 'differential analyser' with photographs of the Manchester analyser, and Hartree's pioneering Meccano model. The most comprehensive of the early essays on the differential analyser, with diagrams and photographs illustrating the design, accounts of the use and applications of the machine, and a useful bibliography. The Differential Analyser was invented by Vannevar Bush, and first described in print in 1931; Bush's invention was the culmination of a line in computer design that goes back to the work of James and William Thomson (Lord Kelvin), most famously the latter's tide-predicting machine. The Differential Analyser was hugely successful, circulating around the world via the unconventional medium of the children's construction-set Meccano. Very good condition: not ex-library; spine with a 5mm split at the top, otherwise very good; internally clean and unmarked throughout; barely noticeable foxing to a handful of page edges, not affecting the Hartree essay.

Original Wraps. Zustand: Very Good in Wraps. dj. First Edition. First Edition. Original Wraps. First printing of Hartree's famous inauguration speech, as issued. "[T]he first booklet on electronic computers separately published by a conventional publisher, and also one of the earliest discussions of how these machines could be used in scientific calculations . Hartree reported his experiences with ENIAC and touched upon the possible future applications of large general-purpose computers in science, medicine and economics". [Origins of Cyberspace 649] This work marks tipping point between computers being an academic and scientific curiosity to a tool which would revolutionize scientific research and the world as a whole. "This can be seen as the start of Hartree's work on bringing computers and their potential to the attention of the scientific community." [Dictionary of Scientific Biography]. [N.B. Published in 1947, there is an interesting question as to whether Hartree knew of the classified work done at Bletchley park and the creation and use of the Colossus machines for code-breaking purposes.however, he certainly moved in social and scientific circles which suggest he might.] Uncommon generally, scare as issued and found here.

Hardcover. Zustand: very good. first edition. First printing of this critical work in the history of computing and a foundational text that launched a circulation through an international scientific journal. In "Nature", Vol 158. October - December, 1946. Entire volume offred with ENIAC [Electronic Numerical Integrator And Computer] article Pp. 500-506. [Entire volume: Pp. 459-956]. Hartree, a British mathematician, first learned of ENIAC in 1945, when he saw the as-yetuncompleted machine during a visit to the Moore School at the University of Pennsylvania. It was here that this first general-purpose Turing complete digital electronic computer, was built between 1943 and 1946. The first computer course was given at the Moore School in Summer 1946, leading to an explosion in computer development all over the world. Hartree was a participant in the lectures, advising on nonmilitary uses of the ENIAC while being the first Englishman to work with the machine. Later, Hartree helped stimulate the development of more powerful computers like Cambridge University's EDSAC. The ENIAC was 10 feet high, and 3 deepand contained 18,000 vacuum tubes, about 70,000 resistors, 10,000 capacitors, and 6,000 switches. It consumed 140 kilowatts, so much power that when operated the lights in a nearbytown dimmed. Royal 8vo bound in contemporary cloth.
