- W4249171929 abstract "MR. J. E. SEARS is retiring on March 31 from the superintendentship of the Metrology Division of the National Physical Laboratory, of which Division he has had charge since 1910. His pioneer work and the contributions he has made to the science and art of metrology are outstanding and have won for him a unique place among scientific workers. The important position which metrology occupies to-day in the field of applied science is, in great measure, due to his efforts. An appreciation of the wide range of Mr. Sears' activities may be gathered from the scope of the work of his Division which, while primarily responsible for maintaining standards for, and advancing the technique of measurement of, the fundamental quantities length, mass and time, and the more immediate derivatives area, volume, density, pressure, etc., deals also with the industrial applications of such measurement. The Division is concerned with the design and development, as well as the inspection, of engineers' gauges and precision measuring instruments, gears and hobs, balances and weights, watches and chronometers, volumetric glassware, hydrometers and barometers-even now the list is incomplete. Mr. Sears' flair for designing is shown in the wide variety of measuring instruments and machines developed and constructed in the Division-screw-measuring machines and optical projectors, a primary standard barometer of unique design and a knife-edge balance of exceptionally high accuracy, to cite a few contrasted examples. Under his leadership, many researches of fundamental importance have been carried out ; reference may be made to a determination of the yard and the metre in terms of wave-lengths of light, of the refractive index of air, and of the absolute value of gravity at the National Physical Laboratory." @default.
