This book was released on 2009-09-16 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: A textbook that covers Physical concepts at a basic level for manual therapists specifically . Clinicians in general and manual therapists in particular have a need tounderstand certain, specific aspects of physics to an advanced level.However, many lack prior education in this area, with chemistry and biology 'A' levels being emphasized in terms of entrance requirements. Most textbooks aimed at this field concentrate exclusively on the physics underpinning biomechanics, but the level at which these books are pitched is often too high to allow understanding by students who have an inadequate background in the subject. This book acts, in part, as a primer to address this deficit. Students are also required to understand the basic physics underpinning physiology, biochemistry, radiography and therapeutics. This textbook will be a guide to these specialist areas of knowledge. This text will cover biophysics as a core subject to guide the potential clinician from total ignorance to complete mastery in the areas of physics pertinent to manual medicine and its related disciplines. Self assessment questions at the beginning of each chapter allow readers to check their existing knowledge prior to reading the chapter. Each section builds from basic principles to advanced levels. Clinical focus.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Laboratory Manual of Physics: For Use in High Schools Our special objects in the preparation of this volume may be very simply stated. They are as follows: - 1. We have aimed not to describe classical experiments, but to illustrate the first principles of physics. The simplicity with which this can be done is to us a matter of constant surprise and delight. 2. Our purpose has been to supplement some of the excellent text-books already in use, most of which, however, were prepared with especial reference to the class-room rather than to the laboratory. It will be observed that, almost without exception, the principles which we have sought to illustrate are discussed in each of the seven volumes to which we make reference. 3. One of our main objects has been to reduce to a minimum the expenditure of teaching energy. With this in mind we have placed a list of apparatus at the beginning of each exercise enabling the instructor to prepare quickly and confidently the entire outfit necessary for the experiment. To this end also we have made a special effort to state the "problem," not by merely giving the name of some instrument, but by stating the controlling principle and the point of view from which the entire experiment should be worked out. Economy of teaching energy has also led us to suggest only apparatus which is simple, inexpensive, easily obtained, and easily duplicated. At the same time we have borne in mind the fact that apparatus is not necessarily simple because it is home-made. Indeed, apparatus can be considered cheap only when it combines economy of first cost with economy of thought on the part of the student and economy of energy on the part of the instructor.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Laboratory Manual of Physics If the student has not already pursued the subject of Physics in a text-book, he is recommended to take a text in connection with the course here given, as references are continually made which assume that he is acquainted with the ordinary facts, terms, and laws of Physics. This work is, in fact, so nearly supplementary to Sharpless and Philips's Natural Philosophy, that a few subjects fully treated in the experiments of that book, are passed over here with simple reference to the fact.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Manual of Physical Measurements This manual is an outline of the laboratory experiments given in the one-year and the two-year courses in general Physics at the University of Minnesota. The laboratory work, in these courses, supplements the lectures and recitations, and occupies one two-hour period a week for two and four semesters respectively. The experiments given in a junior course of one semester in electrical measurements are also included in the section on electricity. It is taken for granted that the student has acquired a general knowledge of a subject before it is considered in the laboratory and no attempt is made in the manual at completeness in subject-matter or in explanations. The work is done under the guidance of an instructor who furnishes any additional information necessary. The student should feel that acceptable results depend upon his own ability to properly adjust the apparatus, and he alone should plan and execute the details of the experiments, subject of course to the criticism of the instructor. We here wish to thank Prof. J. Zeleny and Mr. Paul E. Klopsteg for valuable suggestions, criticisms, and assistance during the preparation of this manual.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Physical Laboratory Manual: For Secondary Schools The number and variety of laboratory manuals in physics now on the market are so large that the merits of a new one are hardly to be sought in novelty of content, but rather in the utility of the material chosen from the abundant common store and in the method of presenting it. Believing that these are both matters Of great importance and that the possibilities of improvement in them have not yet been exhausted, the author has written this manual in the hope that it will con tribute toward this end. Since both the choice of material and the method of treat ment are in a large measure determined by the view enter tained in regard to the place and function of the laboratory work in the course in physics, a brief statement on this point seems desirable. Rejecting the extreme view that little im portance is to be attached to any part of the work except the laboratory course, as well as the opposite extreme which rele gates this part of the work to the position of a supplementary adjunct to the old form of text-book instruction, the author has adopted in his teaching and has assumed as the controlling principle in the preparation of this manual the View that the laboratory course should stand in coordinate relationship to the work of the class room; which, in his opinion, should include as important elements qualitative experimental work by the teacher, the systematic study of a good text-book, as large a use of reference books as time and opportunity permit, a constant appeal to the everyday experience of the pupils, and, finally, the recitation or quiz, in which the information gleaned from the several sources is classified, organized into scientific knowledge, and assimilated.
