Preparatory Physics


    THE course here presented is the outgrowth of needs of the classes beginning the study of physics in the Drexel Institute, Philadelphia. It is arranged strictly for laboratory work, and although the ground covered is not very extensive, yet sufficient has been selected for a first course, and that expounded to a very full extent. Mechanics has been chiefly taken in hand, and the numerous problems have been so arranged that the student is able to investigate them experimentally for him self. A glance at the instructions and explanations shows one that the author wishes at every step to instil into the beginner the idea that habits of accurate and thorough observation must be developed, and, further, that students must be careful, complete, and orderly in recording and arranging his results. With this intention most of the experiments are accompanied with printed forms illustrating concise methods of recording the observations. The apparatus alluded to in the text is of a simple nature, and quite sufficient for those beginning the subject. As an introduction, a few pages are devoted to such fundamental points as units, errors and sources of error, coordinates, plotting of curves, &c. Altogether, the book will be found a serviceable and able help to all wishing to take part in the more simple laboratory work.
