"Hartree's chief contribution to science was his development of powerful methods of numerical mathematical analysis, which made it possible for him to apply successfully the so-called self-consistent field method to the calculation of atomic wave functions of polyelectronic atoms, that is, those which in the neutral condition have more than one electron surrounding the nucleus. These calculations involved the numerical solution of the partial differential equations of quantum mechanics for many-body systems subject to the usual boundary conditions" (D. S. B. 6: 147). Chapter 12 is "Organization of Calculations for an Automatic Machine" (pp. 255-273).…

Soft cover. Condición: Near Fine. 1st Edition. Pamphlet in self-wraps, as issued, 216 x 139mm; pp. 1-[30]. EXCEPTIONALLY SCARCE SEPARATE PRINTING OF HARTREE'S IMPORTANT LECTURE ON THE DIFFERENTIAL ANALYZER Hartree's comprehensive lecture on the 'differential analyser' with photographs of the Manchester analyser, and Hartree's pioneering Meccano model. 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.

8vo. xiv, 287 pp. 31 figs., bibliog., index. Navy cloth, gilt spine, dust-jacket. Ownership rubber stamps of Robert L. White. Fine. FIRST EDITION. "Calculation originally, and over a long period, meant numerical calculation â" the repertoire of arithmetical operations such as addition, subtraction, multiplication and division, and procedures such as extraction of square roots, which could be applied to arbitrary numbers: integers, fractions, and rational, irrational and transcendental numbers. Subsequent developments of such procedures into powerful methods for the solution of general mathematical problems in numerical terms came to known, in English, as numerical analysis."

First UK edition of 'the first comprehensive exposition of electronic digital computing', originally published the previous year in the US. In addition to his significant contributions to ballistics and quantum theory, British mathematician Douglas Hartree (1897-1958) was a leader in efforts to automate scientific calculations. He was 'involved in the development of the digital electronic computer, which emerged from wartime attempts to automate calculation further. In 1946 Hartree's advice was sought in the application of the United States army's ENIAC (electronic numerical integrator and computer) to the production of ballistic tables' (Oxford Dictionary of National Biography). The present volume is 'based upon a series of lectures delivered at the University of Illinois in 1948. These lectures were intended for a well-informed scientific audience outside the tiny group of professionals then involved with electronic computing. They represented the first comprehensive exposition of electronic digital computing, and this book was one of the first two treatises on the subject. The other book, Edmund Berkley's Giant Brains or Machines That Think was written for a more popular audience and achieved greater sales. Reflecting Hartree's English background, this book contained more information on the English machines than did Berkley's. Foremost among the digital machines discussed in Hartree's work are the Harvard Mark I and ENIAC. Chapter 8, entitled "Projects and Prospects", contains the first generally available comprehensive account of the stored-program machines then in development, including EDVAC, ACE, and EDSAC' (Hook & Norman, Origins of Cyberspace 652). First UK edition, first impression; tall 4to; diagrams and monochrome illustrations from photographs throughout the text, neat contemporary ownership inscription to the front free endpaper, contents toned; original burgundy cloth, titles to spine gilt, spine rolled, cloth rubbed and marked, corners bumped, very good condition; 138pp. Hook & Norman, Origins of Cyberspace 652.…

Hardcover. Condición: 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.
