Astrology in a Nutshell

11.99 $ (Print)8.99 $ (eBook)

The contents of this book are of great value in educating the human mind, especially in its appreciation of the fact, that "Order is Heaven's First Law."
This may not be realized in a single reading. We advise repeated readings of the whole book before attempting to practice its lessons. Each reading will throw a new flash of light upon minds unfamiliar with Astrology.
Superficial readers might judge the lessons herein given to be tautological, but the author deems these repetitions necessary to impress certain important facts upon the student.
Repetitions in teaching are lposgycichofactors. The teacher who never alludes to a matter but once would be apt to make a superficial impression.

Great Astronomers (Galileo Galilei)

Great Astronomers (Galileo Galilei)

8.99 $ (Print)2.99 $ (eBook)

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.

Great Astronomers (Isaac Newton)

24.99 $ (Print)6.99 $ (eBook)

IT was just a year after the death of Galileo, that an infant came into the world who was christened Isaac Newton. Even the great fame of Galileo himself must be relegated to a second place in comparison with that of the philosopher who first expounded the true theory of the universe.

Great Astronomers (Nicolaus Copernicus)

Great Astronomers (Nicolaus Copernicus)

8.99 $ (Print)2.99 $ (eBook)

Copernicus, the astronomer, whose discoveries make him the great predecessor of Kepler and Newton, did not come from a noble family, as certain other early astronomers have done, for his father was a tradesman. Chroniclers are, however, careful to tell us that one of his uncles was a bishop. We are not acquainted with any of those details of his childhood or youth which are often of such interest in other cases where men have risen to exalted fame.

The Principle of Relativity: (Original Papers)

The Principle of Relativity: (Original Papers)

14.99 $ (Print)

HISTORICAL INTRODUCTION
Einstein's first paper on the restricted 'Theory of Relativity', originally published in the 'Annalen der Physik' in l905. Translated from the original German Papers by Dr. Meghnad Saha

Lord Kelvin writing-in 1893, in his prefaceto the English edition of Hertz's Researches on Electric Waves, says" many workers and many thinkers have helped to build up the nineteenth century school of plenum, one ether for light, heat, electricity, magnetism; and the German and English volumes containing Hertz's electrical papers, given to th

The Quantum Theory: “With Fifteen Diagrams”

The Quantum Theory: “With Fifteen Diagrams”

14.99 $ (Print)

THE old saying that small causes give rise to great effects has been confirmed more than once in the history of physics. For, very frequently, inconspicuous differences between theory and experiment (which did not, however, escape the vigilant eye of the investigator) have become starting points of new and important researches.
Out of the well-known Michelson-Morley experiment, which, in spite of the application of the most powerful methods of exact optical measurement, failed to show an influence of the earth's movement on the propagation of light as was predicted by classical theory, there arose the great structure of Einstein's Theory of Relativity. In the same way the trifling difference between the measured and calculated values of black-body radiation gave rise to the Quantum Theory which, formulated by Max Planck, was destined to revolutionise in the course of time almost all departments of physics.

From Copernicus to Einstein

From Copernicus to Einstein

(eBook)9.99 $ (Print)

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.

Theory of Heat: “From Beginner to Advanced”

Theory of Heat: “From Beginner to Advanced”

(eBook)16.99 $ (Print)

THE AIM of this book is to exhibit the scientific connexion of the various steps by which our knowledge of the phenomena of heat has been extended. The first of these steps is the invention of the thermometer, by which the registration and comparison of temperatures is rendered possible. The second step is the measurement of quantities of heat, or Calorimetry. The whole science of heat is founded on Thermometry and Calorimetry, and when these operations are understood we may proceed to the third step, which is the investigation of those relations between the thermal and the mechanical properties of substances which form the subject of Thermodynamics.

Relativity

Relativity

6.99 $6.99 $

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 problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the thermal properties of light which laid the foundation of the photon theory of light. In 1917, Einstein applied the general theory of relativity to model the large-scale structure of the universe.
