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 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.

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.

My theory is if you have a religion, it's a good one. Because some people don't have any at all.

There's a statistical theory that if you gave a million monkeys typewriters and set them to work, they'd eventually come up with the complete works of Shakespeare. Thanks to the Internet, we now know this isn't true.

My object will be, first, to show by what connections the history of the fossil bones of land animals is linked to the theory of the earth and why they have a particular importance in this respect.

No theory is good unless it permits, not rest, but the greatest work. No theory is good except on condition that one use it to go on beyond.

From this bestial view that the human mind consists of only sense certainty, pleasure and pain, Locke developed an equally bestial theory of the nation. Man originally existed in a State of Nature of complete liberty.

Science is organized common sense where many a beautiful theory was killed by an ugly fact.

Theory not only formulates what we know but also tells us what we want to know, that is, the questions to which an answer is needed.

The theory of evolution is totally inadequate to explain the origin and manifestation of the inorganic world.

Your theory is crazy, but it's not crazy enough to be true.

Being used to scientific terminology and theory it was always natural for me to push this stuff into songs.

They do not merely collect texts; they must also gather data about the context and the informant and, above all, write an analysis of the items based upon the course readings and lecture material on folklore theory and method.

A political theory seeks to find from history the limits of the politically possible.

Land: A part of the earth's surface, considered as property. The theory that land is property subject to private ownership and control is the foundation of modern society, and is eminently worthy of the superstructure.

I have a theory about that, if you have to say something, if you have encourage for one second a prospective acting student - he should not go in to acting.

What has any poet to trust more than the feel of the thing? Theory concerns him only until he picks up his pen, and it begins to concern him again as soon as he lays it down.

In the first quarter of the nineteenth century the experimental proof for the interdependence of the composition and properties of chemical compounds resulted in the theory that they are mutually related, so that like composition governs like properties, and conversely.

Each pursues his own theory, little solicitous to correct or improve it by an attention to what is advanced by his opponents.

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.

By means of microscopic observation and astronomical projection the lotus flower can become the foundation for an entire theory of the universe and an agent whereby we may perceive Truth.

The scientific theory I like best is that the rings of Saturn are composed entirely of lost airline luggage.

But we did conclude that Ray had actually killed Dr. King pursuant to his theory that he was going to be able to get hold of that money. He had learned of this offer through his ties in the Missouri State Penitentiary.

I joined the Army and was sent to the MIT radiation laboratory after a few months of introduction to electromagnetic wave theory in a special course, given for Army personnel at the University of Chicago.

I wanted a theory that would allow one to live outside the office with the same philosophy one uses inside it.

Whether the ice caps melt, or expand - whatever happens - the anthropogenic global warming theorists claim it confirms their theory. A perfect example of a pseudo-science like astrology.

Religion is essentially the art and the theory of the remaking of man. Man is not a finished creation.

I have a theory that the secret of marital happiness is simple: drink in different pubs to your other half.

You know very well that unless you're a scientist, it's much more important for a theory to be shapely, than for it to be true.

This success led my theoretical group to the chemical reactivity theory, extending more and more widely the range of compound and reactions that were discussed.

All theory of modernity in sociology suggests that the more modernity there is, the less religion. In my theory we can realize that this is wrong: atheism is only one belief system among many.

I wouldn't have thought that a wrong theory should lead us to understand better the ordinary quantum field theories or to have new insights about the quantum states of black holes.

The theory of evolution by cumulative natural selection is the only theory we know of that is in principle capable of explaining the existence of organized complexity.

At the present day the crude theory of the sexual impulse held on one side, and the ignorant rejection of theory altogether on the other side, are beginning to be seen as both alike unjustified.

Rational behavior requires theory. Reactive behavior requires only reflex action.
