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.

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.

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.

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.

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.

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.

Many scientists will have to contribute to the solution of the great problem; they will have to follow up and measure all those phenomena in which the atomic structure is directly expressed.

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 movement of the emitters of the spectral lines may be deduced on the basis of the Doppler principle.

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.

The question of the composition of perceptible objects is one which already occupied the mind of the ancient Greeks.

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.

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.

An external electric field, meeting it and passing through it, affects the negative as much as the positive quanta of the atom, and pushes the former to one side, and the latter in the other direction.

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.

In my view the structure of the whole atom was that of an individual, with all its parts interconnected, and the emission of a spectral line appeared to me to be the result of the coherence and co-operation of several electric quanta.

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.

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.

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.

Along a series of lines running from longer to shorter wavelengths the effect of the electric field becomes greater as the serial numbers increase - that is, as the wavelength decreases.

Moreover, the abundance of chemical compounds and their importance in daily life hindered the chemist from investigating the question, in what does the individuality of the atoms of different elements consist.

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.

As a medical doctor, it is my duty to evaluate the situation with as much data as I can gather and as much expertise as I have and as much experience as I have to determine whether or not the wish of the patient is medically justified.

Now, whenever you read any historical document, you always evaluate it in light of the historical context.

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.

So everybody has some information. The function of the markets is to aggregate that information, evaluate it, and get it incorporated into prices.

Sponsors and networks will really go all out and simply evaluate people on the basis of talent.

Faith is the great cop-out, the great excuse to evade the need to think and evaluate evidence. Faith is belief in spite of, even perhaps because of, the lack of evidence.

I can evaluate a player in a very short period of time because I'm very close to that game, very educated in that game and played the game for a long, long time. I wasn't just a guy with talent. I learned a lot about the game.

I knew how many MPs I had assigned to the brigade, how many military prison operations I would be running, but we needed to evaluate how many criminal prison operations we could support.

I am a scholar of life. Every night before I go to sleep, I analyze every detail of what I did that day. I evaluate things and people, which helps me avoid mistakes.

I know the pundits and the news media have carried a lot of commentary about cameras in the courtroom, and there's a lot of controversy about it as a result of the Simpson case. But I have not had enough time to step back and enough time to evaluate that.

But the other notion is, we also believe that those folks closest on the ground that we're holding accountable for the results can decide, and ought to evaluate which programs get results.

There's lots of institutions and lots of different cultures, and so that's the kind of thing that parents need to be able to evaluate, and students themselves, when they make a selection.

To address questions of scientific responsibility does not necessarily imply that one needs technical competence in a particular field (e.g. biology) to evaluate certain technical matters.

Let the future tell the truth, and evaluate each one according to his work and accomplishments. The present is theirs; the future, for which I have really worked, is mine.

I have not fully had the opportunity to evaluate the impact of cameras in the courtroom.

The ability to take pleasure in one's life is a skill and is a kind of intelligence. So intelligence is a hard thing to evaluate and it manifests itself in so many different ways. I do think the ability to know how to live a life and not be miserable is a sign of that.

One way to evaluate your own reputation is to think about what would be said of you at your eulogy.

Take a step back, evaluate what is important, and enjoy life.

Nor should we exclude the possibility that Islamic terrorism may begin to make common cause with Western political extremists of the far Left and far Right.

In addressing a task, one almost always has several possible options, sometimes only a few, and they may all be practical and functional. But they lack the aesthetic aspect that raises it to architecture.

All enterprises that are entered into with indiscreet zeal may be pursued with great vigor at first, but are sure to collapse in the end.

Entropy theory is indeed a first attempt to deal with global form; but it has not been dealing with structure. All it says is that a large sum of elements may have properties not found in a smaller sample of them.

Journeys, like artists, are born and not made. A thousand differing circumstances contribute to them, few of them willed or determined by the will-whatever we may think.

The good parts of a book may be only something a writer is lucky enough to overhear or it may be the wreck of his whole damn life and one is as good as the other.

We're all like children. We may think we grow up, but to me, being grown up is death, stopping thinking, trying to find out things, going on learning.

That a peasant may become king does not render the kingdom democratic.
