Suspended by a cord from the ceiling in the centre of this room was a glass ball, filled with water, used by Mr. Mitchell in his experiments on polarization of light, flashing its dancing rainbows about the room.
Subject and object must be understood as polar pairs, and in physical science polarization, contrast of properties corresponding to contrast of position, is a universal phenomenon. Analogy, therefore, vindicates the assumption that the unknown, like the known, is the field of the operation of contradictory powers. A variety of expression is given this philosophic notion in myths.
And yet, I repeat it, this is precisely the plan of almost all the men who use electricity in therapeutic practice with any regard to its polarization.
It was not long before he saw, to his delight, a new set of foliage starting from the twigs, and after a little time the tree was again flourishing in all its beauty. The electric current had evidently imparted to it a fresh vitality. To insure the success of such an experiment, a proper regard to polarization must be had, such as is taught in the system presented in this book.
A little study will show you that these mental changes are nearly all along the line of Polarization, the change being one of degree rather than of kind. A knowledge of the existence of this great Hermetic Principle will enable the student to better understand his own mental states, and those of other people.
Her ocean reflects the lights of heaven as in a mighty mirror, her atmosphere refracts them like a monstrous lens, the clouds and snow-fields combine them into white, the woods and flowers disperse them into colors. Polarization, interference, absorption, awaken sensibilities in matter of which our senses are too coarse to take any note.
The theory of Helmholtz has the great advantage of representing, not only the phenomena of dispersion, but also, as M. Carvallo has pointed out, the laws of rotatory polarization, its dispersion and other phenomena, among them the dichroism of the rotatory media discovered by M. Cotton. In the establishment of these theories, the language of ordinary optics has always been employed.
Some years subsequently he answered this question by saying that the liquid condition enables the molecule of water to turn round so as to place itself in the proper line of polarization, while the rigidity of the solid condition prevents this arrangement. This polar arrangement must precede decomposition, and decomposition is an accompaniment of conduction.
In a beam of ordinary light the particles of the luminiferous ether vibrate in all directions perpendicular to the line of progression; by the act of polarization, performed here by Faraday, all oscillations but those parallel to a certain plane are eliminated.
His magnet turned the plane of polarization of the beam through a certain angle, and thus enabled it to get through the analyzer; so that 'the magnetization of light and the illumination of the magnetic lines of force' becomes, when expressed in the language of modern theory, the rotation of the plane of polarization.
