JATJNCEY'S interesting manual for students interprets the term ‘modern physics’ very liberallyhe certainly does not restrict it to ‘atomic’ physics. His liberality of interpretation leads, on occasion, to some odd results in the matter of balancefor example, one whole page is devoted to an elementary deduction of the expression for the capacity of a parallel plate condenser, and less than two pages to the subject of cosmic rays. A good deal of space is wisely given to the elementary theory of alternating currents, but it seems to be an error of judgment, in a work which embraces so many topics, to devote 28 pages to “useful mathematics”.
