Originally published in 1925, this book presents the content of a lecture delivered in November 1924 at King's College, London. The text provides a study regarding the ideal aim of physical science, referring to 'modern physical theories' of the time. This book will be of value to anyone with an interest in physics and the history of science.

Originally published in 1914, this volume was created to mark the tercentenary of John Napier's Mirifici Logarithmorum Canonis Descriptio. Written by the prominent English mathematician Ernest William Hobson, the text provides a highly readable introduction to the theory of logarithms and puts their discovery within a historical context. Illustrations are also included. This is a concise and accessible book that will be of value to anyone with an interest in logarithms and the history of mathematics.

Ernest William Hobson (1856-1933) was a prominent English mathematician who held the position of Sadleirian Professor at the University of Cambridge from 1910 to 1931. In this volume, which was originally published in 1931, Hobson focuses on the forms and analytical properties of the functions which arise in connection with those solutions of Laplace's equation which are adapted to the case of particular boundary problems. The investigations take into account functions not, as was the case when they were originally introduced, confined to the cases where degree and order are integral. This is a highly informative book that will be of value to anyone with an interest in spherical and ellipsoidal harmonics.
