Excerpt from Practical Physics
The importance of experimental work in the teaching of Natural Science is now well recognised. Some experimental acquaintance with the phenomena which are being studied is almost indispensable to their proper understanding, and no one would now attempt to teach Physics as a mere "book-work" subject. Practical Physics, however, has a value apart from its function of providing a basis for theoretical teaching. It provides one of the best means of educating the student's powers of accurate observation and accurate reasoning.
For the training to be of real value, however, the observation must be accurate, and the reasoning correct. This accuracy is of greatest importance, just where it is most difficult to obtain it, namely, in the first year's course in the subject. Beginners are only too apt to assume that accuracy is bound up with elaborate and costly apparatus, and is not to be expected from the simple means at their disposal. They thus form habits of slovenly and inaccurate working which it is exceedingly difficult to eradicate afterwards. In Practical Physics as in other things "well begun is half done," and the student who has worked conscientiously and intelligently through the course outlined in the following pages will find few difficulties to be overcome in the remainder of his work in Practical Physics.
The course has been designed to cover the practical work in Physics which is usually demanded of a student in the first medical examination, or in an examination for a school certificate.
