Before observations on any experiment are begun, the theory of the experiment should be mastered as well as the functions of the various parts of the apparatus which is to be used. Without such study, necessary observations may be omitted or taken in the wrong way, and apparatus whose value depends upon its accuracy may be injured permanently because of a lack of knowl edge about its delicate parts. Furthermore it is important to determine the degree of accuracy of every result which is obtained. Errors - For various reasons it is impossible to obtain the absolute value of an unknown quantity.
