HOADLEY'S NEW PHYSICS 



By GEORGE A. HOADLEY, C. E., Sc. D., Professor 

 of Physics, Swarthmore College. 



Elements of Physics (Text-book) ^1.20 



Laboratory Handbook 50 



THIS text-book is straightforward and concise. It tells 

 only what everyone should know, and it covers all col- 

 lege entrance requirements in physics. The funda- 

 mental principles are presented in a logical order. The 

 topics have been selected with the greatest care. The treat- 

 ment is clear and simple, practical and interesting. The in- 

 timate relation between everyday life and applied physics is 

 made plainly evident. 



^ The problems also are practical; they deal with real 

 events in both time and place, based upon things that have 

 happened, rather than upon imaginary cases. Important 

 physical laws are verified by well-arranged demonstrations. 

 ^ The numerical answers to the problems given at the close 

 of the book make it easy for the student to verify the accuracy 

 of his solutions. Many of the illustrations are entirely-jiew 

 to works on physics or are from the photographs of real appli- 

 cations. 



^ The book meets the requirements of the New York and 

 other State Education Departments, and the recommendations 

 of the National Education Association, those of the College 

 Entrance Examination Board, and those of a number of As- 

 sociations of Teachers of Physics. 



^ The Laboratory Handbook contains sixty-two experi- 

 ments, selected with care, and eminently practical. The 

 directions are simple and clear, tJie apparatus required not 

 elaborate. Throughout, the student is trained to profit from 

 his observations, to exercise his ingenuity, and to depend upon 

 himself.
