System costs can be considered in many different ways. For example, the cost for making the system and the cost for operating it may be used as a basic for judging the total cost. The total cost may also be arrived at in another fashion, as, for example, the sum of the fixed cost, variable cost, past investment and other charges. Furthermore, in many cases where systems engineering is required several time phases are involved for which the cost factors may be significant, such as the study phase, the breadboard phase, the prototype phase, and the production phase.

There are other proposals before Congress for amending the transportation acts. One of these contemplates a revision of the method of valuation for rate-making purposes to be followed by a renewed valuation of the railways. The valuations instituted by the Interstate Commerce Commission 10 years ago have not yet been completed. They have cost the Government an enormous sum, and they have imposed great expenditure upon the railways, most of which has in effect come out of the public in increased rates. This work should not be abandoned or supplanted until its results are known and can be considered.

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.

As a result, it has become commonplace in Ferguson for officers to charge multiple violations for the same conduct. Three or four charges for a single stop is considered fairly routine. Some officers even compete to see who can issue the largest number of citations during a single stop – a total that, in at least one instance, rose as high as 14. And we've observed that even minor code violations can sometimes result in multiple arrests, jail time and payments that exceed the cost of the original ticket many times over.

It costs so much to be a full human being that there are very few who have the enlightenment, or the courage, to pay the price.... One has to abandon altogether the search for security, and reach out to the risk of living with both arms. One has to embrace the world like a lover, and yet demand no easy return of love. One has to accept pain as a condition of existence. One has to court doubt and darkness as the cost of knowing. One needs a will stubborn in conflict, but apt always to the total acceptance of every consequence of living and dying.

At the time the Danes decided to back wind power, the cost of electricity produced this way was many times greater than that produced by fossil fuels. The Danish government, however, could see its potential and supported the industry until costs came down. Today Denmark leads the world in both wind power production and the building of turbines; and wind now supplies 21 percent of the country's electricity. One striking aspect of the way that wind power has developed there is that some 85 percent of the capacity is owned by individuals or wind cooperatives, and so power lies in the hands of the people.
