TWENTIETH CENTURY TEXT-BOOKS 



A High School Course in Physics 



By FREDERICK R. .GORTON, Ph.D., Associate 



Professor of Physics, Michigan State Normal 



College. Fully and Practically Illustrated. I2mo, 



Cloth, $1.25 net. 



The author has written a text-book in Physics which is 

 above all things practical, from the point of view of both 

 teacher and pupil. All scientific facts are clearly stated and 

 referred, wherever such reference will be valuable, to the 

 student's own experience and to the ordinary phenomena of 

 his everyday observation. Without sacrificing the essentially 

 scientific nature of the subject the author recognizes it as a 

 science which has a very definite bearing upon everyday life. 



The author believes that the class-room work should be 

 accompanied by suitable laboratory experimentation by the 

 pupils supplemented with demonstrative experiments by the 

 instructor. 



Stress is laid upon the beneficial results to which the study 

 of Physics has led as its development has progressed. Espe- 

 cial attention has been given to the interesting historical 

 development of the subject. Portraits and adequate bio- 

 graphical sketches of many scientists to whom the discovery 

 of great principles is due have been inserted. 



The problems throughout the book eliminate the usual 

 exercises in pure reduction and substitute those of a more 

 concrete and practical nature. 



The apparatus described is as simple as experience has 

 shown to be consistent with satisfactory results. 



The illustrations are abundant and each is given a descrip- 

 tive legend. 



To aid the pupil in reviewing and the teacher in quizzing, 

 there are summaries at the ends of the chapters. 



No subject has been left out that is called for in the report 

 of the College Entrance Requirement Board.
