The Meaning of Relativity: “With Four Diagrams”

The Meaning of Relativity: “With Four Diagrams”

Printed: 14.99 $eBook: 4.99 $

The theory of relativity is intimately connected with the theory of space and time. I shall therefore begin with a brief investigation of the origin of our ideas of space and time, although in doing so I know that I introduce a controversial subject. The object of all science, whether natural science or psychology, is to co-ordinate our experiences and to bring them into a logical system. How are our customary ideas of space and time related to the character of our experiences?

The experiences of an individual appear to us arranged in a series of events; in this series the single events which we remember appear to be ordered according to the criterion of “earlier” and “later”, which cannot be analysed further.

Great Astronomers (Galileo Galilei)

Great Astronomers (Galileo Galilei)

Printed: 8.99 $eBook: 2.99 $

AMONG the ranks of the great astronomers it would be difficult to find one whose life presents more interesting features and remarkable vicissitudes than does that of Galileo. We may consider him as the patient investigator and brilliant discoverer. We may consider him in his private relations, especially to his daughter, Sister Maria Celeste, a woman of very remarkable character ; and we have also the pathetic drama at the close of Galileo's life, when the philosopher drew down upon himself the thunders of the Inquisition.

A Textbook of Chemistry

A Textbook of Chemistry

Printed: 22.99 $

It is believed that the development of our knowledge during the last few years fully justifies this course. The theory of ionization has also been freely used, as the only means we have by which a large class of phenomena can be clearly presented and understood. It seems desirable to give some material which it is not possible to emphasize or teach thoroughly in a brief course and some things which are rather for reference than to be learned. To aid teachers and students in distinguishing such paragraphs, they are indicated by an asterisk.

Oxford: “Illustrated With 100 Illustrations In Colour”

Oxford: “Illustrated With 100 Illustrations In Colour”

Printed: 29.99 $eBook: 2.99 $
Author:
Genres: Art Books, Non-Fiction

AT the east end of the choir aisle of the Cathedral there is a portion of the wall which is possibly the oldest piece of masonry in Oxford, for it is thought to be a part of the original Church of St. Frideswyde, on whose site the Cathedral Church of Christ (to give its full title) now stands. Even so it is not possible to speak with historical certainty of the saint or of the date of her Church, which was built for her by her father, so the legend says, when she took the veil; though the year 740 may be provisionally accepted as the last year of her life.

Dorothy

Dorothy

Printed: 11.99 $eBook: 3.99 $
Author:
Genres: Biography, Classics

So long a time had passed that Dorothy C. had grown to be what father John called "a baker's dozen of years old"; and upon another spring morning, as fair as that when she first came to them, the girl was out upon the marble steps, scrubbing away most vigorously. The task was known locally as "doing her front," and if one wishes to be considerable respectable, in Baltimore, one's "front" must be done every day. On Saturdays the entire marble facing of the basement must also be polished; but "pernickity" Mrs. Chester was known to her neighbors as such a forehanded housekeeper that she had her Saturday's work done on Friday, if this were possible.

Investigations Into the Superphysical

Investigations Into the Superphysical

Printed: 9.99 $

As evolution steadily carries on the mass of humanity, the crest of its wave must ever be advancing towards new and hitherto unexplored — or only partially explored — regions. Great religious teachers have laid down certain doctrines, far-reaching in their consequences, drawn from a knowledge of super-physical worlds, and their followers have accepted these doctrines on faith, since they were incapable of acquiring for themselves the knowledge of the facts on which they were based.
