The electrical resistance of copper is noteworthy in showing a minimum at very low temperatures (~10°K). This phenomenon has been traced to the presence of very small quantities of certain specific metallic solutes, and a corresponding remarkable va

The conception as an “internal size-effect” of internal boundaries in a metal is proposed and discussed in relation to a number of problems. The behaviour of the electrical resistance under a magnetic field is of particular interest and it is sug

The internal energy and molar volume at absolute zero and the characteristic temperature of the inert gas solids, together with solid hydrogen and deuterium, are calculated taking account of zero-point energy. It is found that to a good approximation

Fundamental criticism is made of two recent papers by Meltzer on electrical noise on general and particular grounds. Correction of the errors in the analysis also provides an opportunity for a discussion of the fundamental relation between a stochast

It has not so far proved possible to extend the conventional Brownian movement analysis to a system with an intrinsically non-linear relaxation mechanism (e.g. viscosity or electrical conductivity). In this paper a new statistical hypothesis is propo

A semi-theoretical equation was proposed previously to account qualitatively for the thermoelectric power of metals and alloys, particularly at low temperatures. The consequences of this equation are now examined quantitatively in relation to experim
