"The mind of man has perplexed itself with many hard questions. Is space infinite, and in what sense? Is the material world infinite in extent, and are all places within that extent equally full of matter? Do atoms exist or is matter infinitely divisible?"

Asa Don Brown

"Nanotechnology is manufacturing with atoms."

Asa Don Brown

"You may have heard the world is made up of atoms and molecules, but it's really made up of stories. When you sit with an individual that's been here, you can give quantitative data a qualitative overlay."

Asa Don Brown

"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."

Asa Don Brown

"It is more likely that more than a century will pass before we know the structure of the chemical atoms as thoroughly as we do our solar system."

Asa Don Brown

"The atoms become like a moth, seeking out the region of higher laser intensity."

Quote_1.png
Asa Don Brown

"We may say that a basic substance is one which has a lone pair of electrons which may be used to complete the stable group of another atom, and that an acid is one which can employ a lone pair from another molecule in completing the stable group of one of its own atoms."

"A physicist is an atom's way of knowing about atoms."

Asa Don Brown

"The problems of language here are really serious. We wish to speak in some way about the structure of the atoms. But we cannot speak about atoms in ordinary language."

Asa Don Brown

"It would be a poor thing to be an atom in a universe without physicists, and physicists are made of atoms. A physicist is an atom's way of knowing about atoms."

"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."
Quote_1.png
Johannes Stark
"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."
Quote_1.png
Johannes Stark
"By recognizing that the chemical atom is composed of single separable electric quanta, humanity has taken a great step forward in the investigation of the natural world."
Quote_1.png
Johannes Stark
"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."

Johannes Stark
"The question of the composition of perceptible objects is one which already occupied the mind of the ancient Greeks."
Quote_1.png
Johannes Stark
"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."

Johannes Stark
"The emitters of the spectral series are without exception single atoms, not compounds of atoms."
Quote_1.png
Johannes Stark
"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."
Quote_1.png
Johannes Stark
"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."
Quote_1.png
Johannes Stark
"With this in mind, for some twenty years I have set myself as my particular task the experimental investigation of the connexion between change in the structure and change in the spectra of chemical atoms."
