THIS little book purports to serve as an introduction to the great problems of space, time and motion. The inquiries it is concerned with are very old. Men have been forming ideas concerning space and time since times immemorial, and curiously enough, have been writing and fighting about these things with the greatest interest, even fanaticism.

This has been a strange strife, indeed, having little to do with economic necessities; it has always dealt with abstract things, far removed from our ...

The year 146 B.C. was an annus mirabilis in the development of Roman dominion. Of course it had long been a foregone conclusion that Carthage and Corinth must fall before her, but the actual time of their overthrow was made all the more striking by the fact that both cities perished in the same year, and that both were visited by the same fate.

I have attempted in this story to group some picturesque inci-dents round the person of a young Greek who struggles in vain to resist the destiny of t...

IN ancient times, when the city of Rome was at the height of its power and splendor, it was the custom, as it is in fact now with the inhabitants of wealthy capitals, for the principal families to possess, in addition to their city residences, rural villas for summer retreats, which they built in picturesque situations, at a little distance from the city, sometimes in the interior of the country, and sometimes upon the seashore. There were many attractive places of resort of this nature in th...

Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led to the development of his special theory of relativity. He realized, however, that the principle of relativity could also be extended to gravitational fields, and with his subsequent theory of gravitation in 1916, he published a paper on the general theory of relativity.

He continued to deal with prob...

"Romeo and Juliet" is a tragic play written early in the career of William Shakespeare about two teenage "star-cross'd lovers" whose untimely deaths ultimately unite their feuding households. It was among Shakespeare's most popular plays during his lifetime and, along with Hamlet, is one of his most frequently performed plays. Today, the title characters are regarded as archetypal "young lovers"

PROLOGUE:

Two households, both alike in dignity,

In fair Verona, where we lay our scene,

To present at a single glance a comprehensive view of the History of English Church Architecture from the Heptarchy to the Reformation, and to do this in a manner, which, without taxing too seriously the memory of the student, may enable him to fix in his mind the limits, and the general outline of the inquiry he is about to enter upon, is the object of the present treatise.

Instead therefore of entering, as is usual in elementary works of this nature, into a detailed account of all the parts...

English Grammar is divided into four parts-Orthography, Etymology, Syntax, and Prosody; and as these are points that a good grammarian always stands upon, he, particularly when a pedant, and consequently somewhat flat, may very properly be compared to a table. Latinised English, or Fine English, sometimes assumes the character of Comic English, especially when applied to the purposes of common discourse; as "Extinguish the luminary," "Agitate the coramunicator," "Are your corporeal functions ...

It falls into this difficulty without any fault of its own. It begins with principles, which cannot be dispensed with in the field of experience, and the truth and sufficiency of which are, at the same time, insured by experience. With these principles it rises, in obedience to the laws of its own nature, to ever higher and more remote conditions.

But it quickly discovers that, in this way, its labours must remain ever incomplete, because new questions never cease to present themselves; and t...
