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.

Soft cover. Zustand: 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.
