At the head of these new discoveries and insights comes the establishment of the facts that electricity is composed of discrete particles of equal size, or quanta, and that light is an electromagnetic wave motion. — Johannes Stark Copy Share Image
For under certain conditions the chemical atoms emit light waves of a specific length or oscillation frequency - their familiar characteristic spectra - and… — Johannes Stark Copy Share Image
The emitters of the spectral series are without exception single atoms, not compounds of atoms. — Johannes Stark Copy Share Image
The discovery of various phenomena has led to a recognition of the fact that the chemical atom is an individual which again is itself… — Johannes Stark Copy Share Image
With this in mind, for some twenty years I have set myself as my particular task the experimental investigation of the connexion between change… — Johannes Stark Copy Share Image
The removal of an electron from the surface of an atom - that is, the ionization of the atom - means a fundamental structural… — Johannes Stark Copy Share Image
It is more likely that more than a century will pass before we know the structure of the chemical atoms as thoroughly as we… — Johannes Stark Copy Share Image
Moreover, the abundance of chemical compounds and their importance in daily life hindered the chemist from investigating the question, in what does the individuality… — Johannes Stark Copy Share Image
The question of the composition of perceptible objects is one which already occupied the mind of the ancient Greeks. — Johannes Stark Copy Share Image

Along a series of lines running from longer to shorter wavelengths the effect of the electric field becomes greater as the serial numbers increase… — Johannes Stark Copy Share Image
In my view the structure of the whole atom was that of an individual, with all its parts interconnected, and the emission of a… — Johannes Stark Copy Share Image
If the experimental physicist has already done a great deal of work in this field, nevertheless the theoretical physicist has still hardly begun to… — Johannes Stark Copy Share Image
