The Dimensions of Area

Nature volume 110, page 9 (1922)Cite this article

Abstract

IN my “Physics,” pp. 423–426, it is maintained that it is incorrect to attribute to area (or volume) the dimensions L2 (or L3); but no example of an error arising from such attribution could be given. It has since occurred to me that an excellent and important example is provided by Child's high vacuum current law, according to which σ, the current density, is proportional to (e/m)½V3/2/l2.
