Abstract :
To the Board of Directors: The personnel of the Committee and its general policies have been practically the same as during the preceding Institute year, so that this report is essentially a continuation of the last year´s report. A steady endeavor has been made during the year to connect some practical engineering problems with the achievements and efforts of modern physics, both experimental and mathematical. In these endeavors we have been materially assisted by the two liaison representatives of the American Physical Society, authorized by the Board of Directors in 1927. As a further step in the same direction, the Committee arranged for a general lecture on The Nature of the Electric Arc, which was ably delivered by Professor K. T. Compton at the 1927 Summer Convention in Detroit.
