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.

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.

Photography is a major force in explaining man to man.

If you want something that's going to provide you with a lot of challenges and a variety of different things to do, then you really can't beat a place like the Air Force. I don't mean this to sound like a recruiting pitch. But it's been a lot of fun.

We need to begin an all-out diplomatic offensive on Darfur in order to prepare the way for a peacekeeping force that can ensure protection for the people of Darfur.

The most important quality in a leader is that of being acknowledged as such. All leaders whose fitness is questioned are clearly lacking in force.

Capital is a result of labor, and is used by labor to assist it in further production. Labor is the active and initial force, and labor is therefore the employer of capital.

All that a good government aims at... is to add no unnecessary and artificial aid to the force of its own unavoidable consequences, and to abstain from fortifying and accumulating social inequality as a means of increasing political inequalities.

It is the tendency of the social burdens to crush out the middle class, and to force society into an organization of only two classes, one at each social extreme.

No doubt Western civilization has in the past been full of wars and revolutions, and the national elements in our culture, even when they were ignored, always provided an unconscious driving force of passion and aggressive self-assertion.

We need a strong police force - the Interior Ministry of the Republic of Chechnya. We have to get rid of the traitors who have managed to penetrate into the law-enforcement department.

From the long range point of view, I do not know of anything we can do more important than to make some contribution to the preservation of religion as a vital force in America.

The increase of territory and power of empires by force of arms has been the policy of all great powers, and it has always been possible to get the approval of their state religion.

The exact measure of the progress of civilization is the degree in which the intelligence of the common mind has prevailed over wealth and brute force.

The dedication of the United States Air Force, Special Forces, and others involved in the mission to tracking down terrorists can not be matched. We express our gratitude to these men and women who defend the freedom America represents.

My mom and dad met at UCLA when he as a captain in the Air Force and she was in her junior year.

We believe, in fact, that the one act of respect has little force unless matched by the other - in balance with it... The acting out of that dual respect I would name as precisely the source of our power.

Our little force will march on tomorrow or the day after.

There are not as many women who support the national defense budget now as men. I really think there is a gender gap in the support for the large expenditures that are necessary to modernize the force.

We believe the use of force against Iraq, especially with reference to previous resolutions of the UN Security Council, has no grounds, including legal grounds.

If you are not prepared to use force to defend civilization, then be prepared to accept barbarism.

It's an old adage that the way to be safe is never to be secure... Each one of us requires the spur of insecurity to force us to do our best.

Indiscriminate firing by police on people is absolute barbarism. Instead of solving their problems, the government is trying to suppress the people by force.

We must not enable anyone to impose his personal view regarding religion on others by force, oppression, or pressure.

My mother was a dominant force in my life. She had a very specific idea about education, which was: you should know everything about everything. It was quite simple. There was no exclusivity, and there really was no judgment.

It is the artist who realizes that there is a supreme force above him and works gladly away as a small apprentice under God's heaven.

Through the wholesale destruction of the representatives of a class that from the beginning of history had been the directing and creative force in civilization, a process began which was almost mechanical.

It is astonishing what force, purity, and wisdom it requires for a human being to keep clear of falsehoods.

That's why I ended up leaving school - because it required so much time, and it was such an excellent idea. I figured I would regret not going full force with this idea. It seemed we could make something of it.

What force is more potent than love?

Yet, history has shown that if material force can defeat some ideologies it can no longer obliterate a civilization without destabilizing the whole planet.

There's nothing like a family crisis, especially a divorce, to force a person to re-evaluate his life.

It becomes a giant's task to compute the result when the effect of cross seas, wind at all angles and ever varying force, arched surfaces, head resistance, ratio of weight to area, and the intelligence of the guiding power crop up.

Rape, mutilation, abuse, and theft are the natural outcome of a world in which force rules, in which human beings are objects.

I've reached out to other mayors throughout the United States to form an Olympic Task Force of Mayors, and to community leaders, Congress, and businesspeople. As thousands of people around the country join the movement, it gets more and more exciting.

I think most Americans believe that although it's better not to use military force if you can avoid it, that the world simply doesn't provide us the luxury of giving away military force as an important tool of foreign policy.
