PHYSICS.
Lecture Courses in Elementary Physics. The instruction in
the elements of physics is by means of lectures given twice a week
throughout the year. In these lectures the general laws of mechanics
and heat, electricity and magnetism, and acoustics and optics, are pre
sented. The very large collection of lecture room apparatus possessed
by
the department makes it possible to give experimental demonstra
tions of all important phenomena. The course of lectures is supple
mented by recitations, for which purpose the class is divided into sec
tions of about twenty members each.
Three courses are given, which consist respectively of two, four,
and five exercises a week. The ground covered in these courses is
essentially the same, but the methods of treatment differ, being
adapted in each case to the needs and previous training of the class of
-students for which the course is designed. The successful completion
of the freshman mathematics is in all cases requisite for admission to
these courses.
Courses of Laboratory Instruction. The first year of laboratory
work is devoted to the experimental verification of physical formulae,
to practice in the use of instruments of precision and to the attain
ment of some knowledge of the simpler methods of physical manipu
lation. Students who have completed the first year's work make a
more extended of various physical constants.
study They learn the
use of standard instruments, and become acquainted with the methods
-employed in research. For students of engineering complete courses
in photometry, in the calibration of instruments and in the study and
testing of direct, alternating and polyphase current machinery are
arranged. The opportunities afforded for advanced work in electricity
are unusual.
Every encouragement is offered to advanced students for the carry
ing on of original investigations, and every opportunity is taken to
stimulate a spirit of scientific inquiry. Courses of reading are sug
gested to such students, in connection with their experimental work ;
