The total number of multiplications involved in the practical solution of our problem exceeds 450,000. This task alone would mean a two-year job, at 120 multiplications per hour. Fortunately, the recent invention of the Simultaneous Calculator by Professor Wilbur of the Massachusetts Institute of Technology has made it possible to perform all the necessary computations in a small fraction of the time they otherwise would have required. This apparatus solves nearly automatically a system of nine simultaneous linear equations. (Wassily Leontief)

The inevitable counterpart of specialization is organization. This is what brings the work of specialists to a coherent result. If there are many specialists, this coordination will be a major task. So complex, indeed, will be the job of organizing specialists that there will be specialists on organization and organizations of specialists on organization. More perhaps than machinery, massive and complex business organizations are the tangible manifestation of advanced technology. View quote

To make our position clearer, we may formulate it in another way. Let us call a proposition which records an actual or possible observation an experiential proposition. Then we may say that it is the mark of a genuine factual proposition, not that it should be equivalent to an experiential proposition, or any finite number of experiential propositions, but simply that some experiential propositions can be deduced from it in conjunction with certain other premises without being deducible from those other premises alone.

The problem of distinguishing prime numbers from composite numbers and of resolving the latter into their prime factors is known to be one of the most important and useful in arithmetic. It has engaged the industry and wisdom of ancient and modern geometers to such an extent that it would be superfluous to discuss the problem at length. ... Further, the dignity of the science itself seems to require that every possible means be explored for the solution of a problem so elegant and so celebrated. View quote

Industrial production, the flow of resources in the economy, the exertion of military effort in a war, the management of finances --all require the coordination of interrelated activities. What these complex undertakings share in common is the task of constructing a statement of actions to be performed, their timing and quantity (called a program or schedule), that, if implemented, would move the system from a given initial status as much as possible towards some defined goal.

I cannot...perceive any ground for hoping that any practical good would, while the funding system exists in its present extent, result from the adoption of any of those projects, which have professed to have in view what is called Parliamentary Reform...when the funding system, from whatever cause, shall cease to operate upon civil and political liberty, there will be no need of projects for parliamentary reform. The parliament will, as far as shall be necessary, then reform itself. View quote
