THE LOVE between man and woman has been told in story and poem since long before the days of Sappho. It forms, indeed, the subject of the great bulk of what we call literature. In music, love's domain is less extended. With the exception song and the opera, most of the greatest music has, in its title at least, no hint of the great heart historyof human kind.

In this respect the plastic arts are more allied to music than to literature. The masterpieces in painting and sculpture generally not ...

Charles Darwin's The Origin of Species, published on 24 November 1859, is a work of scientific literature which is considered to be the foundation of evolutionary biology. Its full title was On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life. For the sixth edition of 1872, the short title was changed to The Origin of Species.

Darwin's book introduced the scientific theory that populations evolve over the course of generations...

It was about sixty years ago when there appeared the first glimmerings Of the knowledge which has since ripened into that which we now possess, that neither the molecules of any natural object nor the parts Of which those molecules consist are ever at rest; that, on the contrary, swift and orderly movements are ever in progress among them and within them; and that where bodies appear to us to be stationary, it is only be cause this great internal activity is on too small a scale, the parts mo...

In preparing this book, the author had especially in mind classes in the upper grades of grammar schools, though the work will be found equally well adapted to the needs of any classes of beginners.

The ideas which have guided in the treatment of the subject are the following:

The study of algebra is a continuation of what the pupil has been doing for years, but it is expected that this new work will result in a knowledge of general truths about numbers, and an increased power of clear thinking.

All the differences between this work and that pursued in arithmetic may be traced to the introduction of two new elements, namely, negative numbers and the representation of numbers by letters. The solution of problems is one of the most valuable portions of the work, in that it serves to develop the thought-power of the pupil at the same time that it broadens his knowledge of numbers and their relations. Powers are developed and habits formed only by persistent, long-continued practi...

An Inquiry into the Nature and Causes of the Wealth of Nations, generally referred to by its shortened title The Wealth of Nations, is the magnum opus of the Scottish economist and moral philosopher Adam Smith. First published in 1776, the book offers one of the world's first collected descriptions of what builds nations' wealth, and is today a fundamental work in classical economics. By reflecting upon the economics at the beginning of the Industrial Revolution, the book touches upon such br...

Contantinople, the capital, has a population (probably) of a million and a quarter of in-habitants, or about that of Philadelphia. Among the other important towns in European Turkey are Saloniki, an important shipping centre, with 105,000 inhabitants; Adrianople, which has had a large domestic traffic since the completion of the railway to Northern Europe.

IT is important for purposes of reference, if not directly interesting, to relate so much of Ottoman history as may be necessary for the ...

The materials for the sketch of this astonishing man are sufficiently abundant. We make special use in this place of those charming letters which his daughter wrote to him from her convent home. More than a hundred of these have been preserved, and it may well be doubted whether any more beautiful and touching series of letters addressed to a parent by a dearly loved child have ever been written. An admirable account of this correspondence is contained in a little book entitled "The Private L...

In his later work, Freud proposed that the human psyche could be divided into three parts: Id, ego and super-ego. Freud discussed this model in the 1920 essay Beyond the Pleasure Principle, and fully elaborated upon it in The Ego and the Id (1923), in which he developed it as an alternative to his previous topographic schema (i.e., conscious, unconscious and preconscious).

The id is the completely unconscious, impulsive, childlike portion of the psyche that operates on the "pleasure principle...

In these days of numerous text-books the author who dares still further to increase the number owes to the public, at least, an explanation in which he shall set forth his purpose, however far short of accomplishment he may have fallen.

Accordingly, in this volume, the author's hopes have been: –

(i) To prepare a text-book adapted to the needs of first-year students in physics at Northwestern University. One fear in this connection is that the transfer of a course of lectures from flexible...
