Excerpt from Fluidity and Plasticity Our knowledge of the flow of electrical energy long ago developed into the science of Electricity but our knowledge of the flow of matter has even yet not developed into a coordinate science. In this respect the outcome of the labors of the hydrodynamicians has been disappointing. The names of Newton, Navier, Poisson, Graham, Maxwell, Stokes and Helmholtz with a thousand others testify that this field has been well and competently tilled. Even from the first the flow of liquids has been a subject of practical importance, yet the subject of Hydraulics has never become more than an empirical subject of interest merely to the engineer. Unfortunately the theory is complicated in that the flow of matter may be hydraulic (turbulent), viscous (linear), or plastic, dependent upon the conditions. It was in 1842 that viscous flow was first differentiated from hydraulic flow, and only now are we coming to realize the important distinction between viscous and plastic deformation. Considering the confusion which has existed in regard to the character of flow, it is not surprising that there has been uncertainty in regard to precise methods of measurement and that exact methods have been discovered, only to be forgotten, and rediscovered independently later. As a result, the amount of really trustworthy data in tho literature on the flow of matter under reproducible conditions is limited, often to an embarrassing extent. If we are, to have a theory of flow in general, we must consider matter in its three states. No such general theory has appeared, although one is manifestly needed to give the breath of life to the dead facts about flow: The author offers the theory given in the following pages with the utmost trepidation. Although, he has given several years to the pleasant task of supporting its most important, conclusions, a lifetime would be far too short to complete the work unaided. The author makes no apology for any lack of finality. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
