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.

It's the difficulty we had with Mr. Bean, actually, when it went from TV to film. You certainly discover that you need to explain more about a character.

Divide each difficulty into as many parts as is feasible and necessary to resolve it.

The honest truth is that if this government were to propose the massacre of the first-born, it would still have no difficulty in getting it through the Commons.

A lot of these industries are having difficulty finding reliable workers with the skills they require.

Bad company is like a nail driven into a post, which, after the first and second blow, may be drawn out with little difficulty; but being once driven up to the head, the pincers cannot take hold to draw it out, but which can only be done by the destruction of the wood.

I think the biggest difficulty is that when I'm here in America, there's a necessity of using English, so I really have a great sense of really wanting to learn, but unfortunately when I head back to Japan, the necessity vanishes and so does my enthusiasm about learning.

I'm sure that you could go back and make a graph showing that all the killings of black males increased in times of economic difficulty. As a matter of fact, a black man was lynched last year.

Conquering any difficulty always gives one a secret joy, for it means pushing back a boundary-line and adding to one's liberty.

Let there be no illusions about the difficulty of forming this kind of a national community. It's tough, difficult, not easy. But a spirit of harmony will survive in America only if each of us remembers that we share a common destiny.

The accumulation of skill and science which has been directed to diminish the difficulty of producing manufactured goods, has not been beneficial to that country alone in which it is concentrated; distant kingdoms have participated in its advantages.

For example, in painting the form arises from abstract elements of line and color, while in cinema the material concreteness of the image within the frame presents - as an element - the greatest difficulty in manipulation.

The difficulty of literature is not to write, but to write what you mean; not to affect your reader, but to affect him precisely as you wish.

The mind unlearns with difficulty what it has long learned.

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.

Perhaps, to the uninformed, it may appear unaccountable that a man should be able to retain in his memory such a variety of learning; but the close alliance with each other, of the different branches of science, will explain the difficulty.

Given the difficulty of resisting such temptations over the longer run, a proper concern for the welfare of congressional souls may well be the ultimate argument in favor of term limitations.

If most people are not willing to see the difficulty, this is mainly because, consciously or unconsciously, they assume that it will be they who will settle these questions for the others, and because they are convinced of their own capacity to do this.

It is a high patriotic duty that we support and sustain the men who have been placed in position of difficulty, burden, responsibility, and even danger as the result of our suffrages.

Give yourself an even greater challenge than the one you are trying to master and you will develop the powers necessary to overcome the original difficulty.

The difficulty with this conversation is that it's very different from most of the ones I've had of late. Which, as I explained, have mostly been with trees.

The difficulty is to try and teach the multitude that something can be true and untrue at the same time.

Little Sparta is a garden in the traditional sense. It is perhaps not like other modern gardens, but I think that other times would have had no difficulty with it.

By no means do I anticipate screening those who come on to campus... And I have no difficulty if a bishop across the country or some local pastor may say that's not Catholic teaching - that's fine.

Surmounting difficulty is the crucible that forms character.

Sports is a metaphor for overcoming obstacles and achieving against great odds. Athletes, in times of difficulty, can be important role models.

I am, really, a great writer; my only difficulty is in finding great readers.

Whatever the medium, there is the difficulty, challenge, fascination and often productive clumsiness of learning a new method: the wonderful puzzles and problems of translating with new materials.

I think one ages and one dates. I tend to have a good deal of difficulty in liking some of the new poets.

I know my own soul, how feeble and puny it is: I know the magnitude of this ministry, and the great difficulty of the work; for more stormy billows vex the soul of the priest than the gales which disturb the sea.

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

The tax on capital gains directly affects investment decisions, the mobility and flow of risk capital... the ease or difficulty experienced by new ventures in obtaining capital, and thereby the strength and potential for growth in the economy.

What we're seeing early on is Democrats rallying around Al Gore, Republicans rallying around George Bush and the difficulty of anybody else to get any room in the race.

Difficulty, my brethren, is the nurse of greatness - a harsh nurse, who roughly rocks her foster - children into strength and athletic proportion.

Some people carry their hearts in their heads; very many carry their heads in their hearts. The difficulty is to keep them apart, yet both actively working together.
