Sample text

Errors can only be minimized by design. There are several distinct types of error in the process of observation. The simplest type of error is called random error. Random errors are usually small deviations from the ‘true value’ of a measurement that occur by accident, by unforeseen jitter in the system, or by some other influence. By their nature, we are usually ignorant of the cause of random errors, otherwise it might be possible to eliminate them. The important point about random errors is that they are distributed evenly about the mean value of the observation.

Its width characterizes the standard deviation. It is therefore the generic model for all measurement distributions. The normal distribution was first derived by DeMoivre in 1733 while dealing with problems involving the tossing of coins; the law of errors was deduced theoretically in 1783 by Laplace. He started with the assumption that the total error in an observation was the sum of a large number of independent deviations, which could be either positive or negative with equal probability, and could therefore be added according to the rule explained in the previous sections.

18 SCIENCE AND ITS METHODS During the Enlightenment, philosophers even came to believe that scientific inquiry could yield truths about human nature and thus that ethical principles might be best derived from such truths; this would therefore be a basis for a new order of society. In the eighteenth century, others began to realize that this vision was flawed. David Hume discovered an important twist, namely that predictions about events that are not observed cannot be proven to be true or false, not even to be probable, since observation alone cannot see into the future, and cannot attempt to assess the cause of a phenomenon.
