The fall of Aleppo will be hugely tragic—“psychologically and optically devastating,” says Itani.
optically, its rigidity and density are both felt, since optical disturbances are essentially electromotive.
Polarizing contact-lenses—prescription or optically neutral.
As, for instance, strychnine racemate, a compound of racemic acid with the optically active strychnine.
The occurrence of hemihedral faces was considered by Pasteur to be a sufficient criterion for an optically active substance.
To use the scientific phrase, they are not optically continuous.
There are a number of optically bright lines of longer wave-length.
And when brought to the laboratory, it is found that chemically these lignites vary even more than they do optically.
I have tried many other plans; indeed the possible methods of optically superimposing two or more images are very numerous.
All solutions of plant proteins are optically active, rotating the plane of polarized light to the left, in every case.
