the constitution of the medium but also its condition of movement and the physical agents to which it is subordinated.
eadyidihhas quoted4 years ago
The same thing is true for the conduction of heat or electricity, for magnetization, for polarization, etc.
eadyidihhas quoted4 years ago
It was the study of optics which first showed that the propagation of light in a crystal is dependent upon the elements of symmetry in that crystal
eadyidihhas quoted4 years ago
Nature furnishes us the idea of a plane of symmetry and of an axis of symmetry.
eadyidihhas quoted4 years ago
a condition of space characteristic of the medium in which a given phenomenon occurs.
eadyidihhas quoted4 years ago
Thus a regular flower of four petals has an axis of symmetry of the order four, or a quarternary axis

potential energies, brought about the establishment of the principle of the conservation of energy whose application is entirely general.
eadyidihhas quoted4 years ago
I think it is necessary to introduce into physics the ideas of symmetry familiar to crystallographers.”
eadyidihhas quoted4 years ago
elements of symmetry which it introduces are related to all the phenomena of physics without exception
eadyidihhas quoted4 years ago
When certain causes produce certain effects, the elements of symmetry in the causes ought to reappear in the effects produced.

theoretical work1 on the formation of crystals, and the capillary constants of the different faces.
