    Excerpt from Preparatory Physics: A Short Course in the Laboratory

    It may be well to state here my reasons for omitting a portion of the experiments recommended in the Harvard pamphlet. It is obviously desirable that all experiments performed by the student, especially if he is a beginner, Shall give results sufficiently near the truth to inspire him with confidence in his own work and in experimental methods of investigation. This condition is admirably ful filled by the work on Mechanics, for with proper care, even with the somewhat rough apparatus employed in this course, it is possible to obtain results which differ not more than one per cent. From the true values.

    In some other branches of the subject, I have not found this to be the case. In investigating the subject of latent heat, for example, or that of specific heat, it is necessary, in order to obtain accurate results, to employ more elabo rate apparatus and much more careful and exact methods of research than are possible in such a course as is here pre sented. A student of this grade, using crude apparatus, will obtain results which may differ as much as fifty per cent. From the truth. This can do nothing but harm. It will lead him to distrust laboratory methods as means of ascertaining the truth, and to suppose that, as he himself cannot expect to obtain accurate quantitative results, it is not necessary for him to exercise care either in his reason ing or in his work.
