In a recent communication to this Society Dr Hartree has put forward a method for calculating the field of anatom containing many electrons. Each orbit—to borrow a metaphor from the old quantum theory—is related to a wave-function Ψ which obeys Schrödinger's equation. The potential energy used in this equation is due…
Abstract 1. No systematic investigation on this subject has yet been attempted. The efforts made to group these materials in a series according to the charges generated when they are rubbed two at a time are of uncertain value because of (1) impurities of substance and surface, (2) indeterminate initial surface strain…
Abstract Blindfolded persons walk, run, swim, row, and drive automobiles in clock‐spring spiral paths of greater or less regularity when attempting a straightaway. The spirals turn either right or left in one and the same individual, and may do so even in one experiment. But either right or left turns predominate in t…
Abstract It is shown that β-brass, which has a crystal structure similar to that of α-iron, behaves in a similar, though not identical, manner when distorted. The peculiar feature of the distortion of iron crystals, namely, the fact that slip does not occur on a definite crystallographic plane, is repeated in β-brass…
Abstract In the present paper we shall attempt to collate the results of four separate lines of research which, taken together, appear to provide some interesting checks between theory and experiment. The investigations to be considered are (1) the discussion by Waller* and by Wentzel,† on the basis of the quantum (wa…

Je me suis proposé dans ce travail de réaliser par l'expérience de nouveaux exemples d'épitaxie entre cristaux d'espèces différentes, d'établir la loi qui régit l'orientation relative des deux cristaux et de préciser les facteurs qui conditionnent le dépôt épitaxique. 1). J'ai été ainsi amené à découvrir une nouvelle…

THE STRENGTH OF CONCRETE MADE FROM SOUND, DURABLE MATERIALS DEPENDS UPON THE EXTENT TO WHICH THE SOLID PARTICLES ARE BONDED TOGETHER AND THE AMOUNT OF SOLID MATERIALS IN THE CONCRETE. THE BOND DEPENDS UPON THE PROPORTION OF CEMENT IN A GIVEN QUANTITY OF CONCRETE AND THE AMOUNT OF MIXING WATER. USING THESE BASIC PRINCI…

Abstract The problem of the velocity of the particles emitted from the nuclei of dis integrating radioactive atoms has always attracted considerable attention. It was early established that in the case of the α-rays all the particles from one substance were emitted with the same velocity, and the latest experiments of…

Abstract 1. Hexacyaneisensalze werden durch Einwirkung von Licht oder Wärme oder bei Gegenwart eines Überschusses von Wasserstoffion in ihrer wäßrigen Lösung allmählich in das Aquopentacyankomplexsalz verwandelt.
An account is given of an investigation of the alga-flora of four English soils by means of dilution cultures of freshly gathered samples of soil from the top, second, fourth, sixth and twelfth inch depths and from the top 6 in. mixed. A counting method is described applicable to the green algae and diatoms, by means…

ABSTRACT Thermal expansion data on soda‐silica, soda‐lime‐silica, soda‐magnesia‐silica, soda‐lime‐magnesia‐silica, soda‐alumina‐silica, soda‐lime‐alumina‐silica, and other glasses, over the range of 25° to 90°C are presented and compared. The relations existing between thermal expansion and chemical composition of the…
