"The most common and most important result of them is that the nature and size of the effect on corresponding series of different elements are largely an expression of the peculiarity of their atomic structure - or, at least, of the structure of the surface."

"Like the ocean, never forget to be generous with your love."
"Regardless of all our pretenses, deep within, we are still unconsciously the same old cave-people."
"Forgetting nature is like forgetting your mother. Remember you are a child of nature. You are connected to it and belong to it. So don't forget to protect her."
"Keep the environment clean and the waters clear as crystal."

"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."
"By allowing the positive ions to pass through an electric field and thus giving them a certain velocity, it is possible to distinguish them from the neutral, stationary atoms."
"We have learnt through experience that when an electrical ray strikes the surface of an atom, an electron, and in some circumstances a second and even a third electron, can be detached."
"The movement of the emitters of the spectral lines may be deduced on the basis of the Doppler principle."
"The removal of an electron from the surface of an atom - that is, the ionization of the atom - means a fundamental structural change in its surface layer."
"A beam of luminous hydrogen canal rays has, owing to its velocity, exactly the same direction as that of the electric field in which it may be made to move."
"If the experimental physicist has already done a great deal of work in this field, nevertheless the theoretical physicist has still hardly begun to evaluate the experimental material which may lead him to conclusions about the structure of the atom."
"The discovery of various phenomena has led to a recognition of the fact that the chemical atom is an individual which again is itself made up of several units into a selfcontained whole."
"The emitters of the spectral series are without exception single atoms, not compounds of atoms."
"For under certain conditions the chemical atoms emit light waves of a specific length or oscillation frequency - their familiar characteristic spectra - and these can come in the form of electromagnetic waves only from accelerated electric quanta."
