In the absence of a magnetic field the period of all these oscillations is the same. But as soon as the electron is exposed to the effect of a magnetic field, its motion changes.

I should point out, however, that at first some difficulty was experienced in observing the phenomena predicted by the theory, owing to the extreme smallness of the variations in the period of oscillation.

It was not simply out of a spirit of contradiction that I exposed a light source to magnetic forces. The idea came to me during an investigation of the effect discovered by Kerr on light reflected by magnetic mirrors.

On the basis of Lorentz's theory, if we limit ourselves to a single spectral line, it suffices to assume that each atom (or molecule) contains a single moving electron.

I count myself fortunate to be able to contribute to this work; and the great interest which the Royal Swedish Academy of Sciences has shown in my work and the recognition that it has paid to my past successes, convince me that I am not on the wrong track.

We studied the light source in the direction of the magnetic force, we perforated the poles of the magnet; but even in the direction of the magnetic lines of force we found that our result was confirmed.

Had we really succeeded therefore in altering the period of vibration, which Maxwell, as I have just noted, held to be impossible? Or was there some disturbing circumstances from one or more factors which distorted the result?

Moreover, photography has made it possible to fix these images and now provides us with a permanent record of each observed spectrum, which can be measured out at any time.

The rotation of the polarization plane is extraordinarily small in all gases, thus also in sodium vapour.

Nature gives us all, including Prof. Lorentz, surprises. It was very quickly found that there are many exceptions to the rule of splitting of the lines only into triplets.

In the absence of a magnetic field the period of all these oscillations is the same. But as soon as the electron is exposed to the effect of a magnetic field, its motion changes.

The magnetic cleavage of the spectral lines is dependent on the size of the charge of the electron, or, more accurately, on the ratio between the mass and the charge of the electron.

Now if this electron is displaced from its equilibrium position, a force that is directly proportional to the displacement restores it like a pendulum to its position of rest.

According to well-known electrodynamic laws, an electron moving in a magnetic field is acted upon by a force which runs perpendicular to the direction of motion of the electron and to the direction of the magnetic field, and whose magnitude is easily determined.

Now all oscillatory movements of such an electron can be conceived of as being split up into force, and two circular oscillations perpendicular to this direction rotating in opposite directions.

Without feeling abashed by my ignorance, I confess that I am absolutely unable to say. In the absence of an appearance of learning, my answer has at least one merit, that of perfect sincerity.

That a great battle must soon be fought no one could doubt; but, in the apparent and perhaps real absence of plan on the part of Lee, it was impossible to foretell the precise scene of the encounter.

Courage is not the absence of despair; it is, rather, the capacity to move ahead in spite of despair.

Peace is not the absence of war, but a virtue based on strength of character.

The absence of alternatives clears the mind marvelously.

With the absence of a flu vaccination last year, I did not take a flu shot; but there is still some immunity that carries over from year to year; but about every 30 years, there is a major change in the genetics of the flu virus.

And as far as false hope, there is no such thing. There is only hope or the absence of hope-nothing else.

The longest absence is less perilous to love than the terrible trials of incessant proximity.

Life has become the ideology of its own absence.

There is a movement to get an international criminal court in the world, voted for by hundreds of states-but with the noticeable absence of the United States of America.

I wish you to inform the Court that my absence, though deliberate, is not intended in any way to be disrespectful. Nor is it prompted by any fear of the punishment which might be inflicted on me.

Where choice begins, Paradise ends, innocence ends, for what is Paradise but the absence of any need to choose this action?

In the absence of that, I am happy to play solo, but I don't think there is any comparison.

For many Americans, including many who are employed, going to the doctor when they fall ill or become injured may not be an option because of the absence of health insurance.

The situation in the region is flammable and may explode at any moment, because of the crucial events and because of the absence of justice in executing the international legitimacy resolutions, regarding the Israeli Arab cause and the oppression on Palestinians by Israelis.

It is the maintenance of slavery by law in a state, not parallels of latitude, that makes its a southern state; and the absence of this, that makes it a northern state.

My dear, the duty that devolved wholly on you in my absence of guiding and expanding the minds of our dear children is a laborious one and a responsible one.

So far as discipline is concerned, freedom means not its absence but the use of higher and more rational forms as contrasted with those that are lower or less rational.

I was court-martial in my absence, and sentenced to death in my absence, so I said they could shoot me in my absence.

Of all the bewildering things about a new country, the absence of human landmarks is one of the most depressing and disheartening.

Instead, in the absence of respect for human rights, science and its offspring technology have been used in this century as brutal instruments for oppression.

When I came back to Dublin I was courtmartialed in my absence and sentenced to death in my absence, so I said they could shoot me in my absence.

Peace is not absence of conflict, it is the ability to handle conflict by peaceful means.

It would be hard to ignore the absence of democracy in any Arab nation.

Grace is the absence of everything that indicates pain or difficulty, hesitation or incongruity.

To observe people in conflict is a necessary part of a child's education. It helps him to understand and accept his own occasional hostilities and to realize that differing opinions need not imply an absence of love.

Coughs seem very common here, especially among the children, though people look strong and healthy, but in the absence of proper statistics one cannot undertake to say whether the district is a healthy one or not.

Absolute liberty is absence of restraint; responsibility is restraint; therefore, the ideally free individual is responsible to himself.

Being solitary is being alone well: being alone luxuriously immersed in doings of your own choice, aware of the fullness of your won presence rather than of the absence of others. Because solitude is an achievement.

Judicious absence is a weapon.

There is no surer mark of the absence of the highest moral and intellectual qualities than a cold reception of excellence.

In dreams the truth is learned that all good works are done in the absence of a caress.

In the absence of evidence, superstition. It's a Middle Ages thing. That's my theory anyway.

Peace must be more than the absence of war.
