SAUER, R., and H. POESCH, Integrating

Machine for Solving Ordinary Differential

Equations, _Engineers Digest_ (American

Edition), vol. 1, May 1944, pp. 326-328.

From the historical point of view there are some interesting papers on

a machine for solving differential equations by Sir William Thomson

(Lord Kelvin), including one by his brother James Thomson. They are

in the _Proceedings of the Royal Society_, vol. 24, Feb. 1876, pp.

262-275. The method of integration by a machine is described, but

the state of machine tools at the time was such that no accurate

mechanism was constructed. Another interesting paper foreshadowing the

differential analyzer is:

Engine_, Chicago: University of Chicago,

thesis for Master’s Degree, 1923, 28 pp.

analyzers are covered in:

NETWORK ANALYZERS

A third branch of the analogue calculating machine is the network

analyzer. To solve problems, this machine uses the laws governing a

network of electrical circuits. For example, an electric power company

with a system of power lines over hundreds of miles may have a problem

about electrical power: will an accident or a sudden demand cause a

breakdown anywhere in the system? In the General Electric Company

in Schenectady, N. Y., there is a machine called the A.C. Network

Analyzer. All the properties of the power company’s network of lines

can be fed on a small scale into the analyzer. Certain dials are turned

and certain plugwires are connected. Then various kinds of “accidents”

and “sudden demands” are fed into the machine, and the response of the

system is noted. The answers given by the machine are multiplied by the

proper scale factor, and in this way the problem of the power company

is solved.

There are two kinds of problems that network analyzers are built to

solve: the steady state conditions and the transient conditions. For

example, you may not overload a fuse with an electric iron when it is

plugged in and being used, but as you pull out the cord, you may blow

the fuse: the steady state does not overstrain the system, but the

transient does.

ENIAC, THE ELECTRONIC NUMERIC INTEGRATOR AND CALCULATOR

There is as yet no full-scale, published scientific account of the

Eniac. At the Ballistic Research Laboratories, Aberdeen, Md., where

the machine now is, there are a few copies of some long mimeographed

reports on the machine and the way it works. These were prepared by

H. H. Goldstine and others when at the Moore School of Electrical

Engineering, as a part of the contract under which the machine was

constructed for the U. S. Government. It is possible that these reports

might be consulted on request by serious students.
