Thus at the beginning of 1906 it seemed to be established that the emitters of the spectral series of chemical elements are their positive atomic ions.
We can in fact first place the beam of rays of moving positive atomic ions in a plane perpendicular to the axis in which we see the spectral lines emitted by them.
How does one kill fear I wonder? How do you shoot a specter through the heart slash off its spectral head take it by its spectral throat?
Science is spectral analysis. Art is light synthesis.
