REPORT OF THE PHYSICS DEPARTMENT. 



President F. S. Kedzio, 



East Lansing, Michigan. 

 Dear Sir : 



A brief annual report of the Physics Department for the year ending June 

 30, 1921, is herewith presented. 



The personnel of the department was as follows : 

 Charles W. Chapman, Professor of physics. 

 William E. Laycock, Associate professor of physics. 

 Edwin Morrison, Assistant professor of physics. 

 Eugene B. Butler, Instructor in physics. 

 Wilbur H. Thies, Instructor in physics. 

 S. EHzabeth Morrison, Laboratory assistant and clerk. 

 Ralph M. Harford, College photographer. 

 Wallace W. Tappan, Caretaker of the tlepartment. 



Mr. Butler and Mr. Thies began their duties as instructors, September 1, 

 1920. 



Practically no equijjment has been purchased throughout tlie whole year, 

 but through our own efforts some apparatus has been added. In one week 

 we built 4 magnetometers the approximate cost of which would have exceed- 

 ed $25 each had we bought apparatus of an eciual grade. We have increased 

 the capacity of our storage battery switchboard so that we now have 112 

 volts. Besides, we have again rewound our rotary converter. This policy 

 was adopted by us in order that the Physics department might do its part in 

 the conservation of funds at a time when the assistance of all departments 

 was needed, as the college financial condition was practically in a state of 

 bankruptcy. 



The following revisions, and additions, have been made in and to our work 

 in physics. 



(a) Physics 4b, which has previously Ijeen a three-credit course, becomes 

 a five-credit course. 



(b) Laboratory fees have been revised as follows: fee for a two-hour 

 laboratory period will be $1.50, while a $3.00 fee will be required for a 

 four-hour laboratory jjeriod. Physics 5, laboratory fee will be $5.00. 



(c) Physics 3d and Physics 3e which have been required of sophomore 

 home economics students for several years past, now becomes an elective. 



(d) Physics 3, "Mechanics and Electricity" (spring term-5 credits), will 

 henceforth be required of freshman home economics students. 



(e) The agricultural and engineering courses remain practically un- 

 changed, with the following modification in laboratory work for the 

 engineers (Physics 2f-.'pring term) : 



To make the engineering laboratory work of a higher collegiate 

 grade and yet add to its practical value, six new laboratory problems 

 were worked out to replace the six stereotyped experiments that 

 have been used in practically all colleges for the last ten to fifteen 

 years. One of the new problems coml)incs three of the former
