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

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.

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.

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.

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

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.

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.

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.

The emitters of the spectral series are without exception single atoms, not compounds of atoms.

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.

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.

What? A great man? I only ever see the ape of his own ideal.

Life affords no greater responsibility, no greater privilege, than the raising of the next generation

Ports are necessities, like postage stamps or soap, but they seldom seem to care what impressions they make.

To argue against any breach of liberty from the ill use that may be made of it, is to argue against liberty itself, since all is capable of being abused.

There is no sweeter innocence than our gentle sin

Life involves other people and it is a compromise.

The heart of God loves a persevering worshipper who, though overwhelmed by many troubles, is overwhelmed even more by the beauty of God.

There is not, perhaps, to a mind well instructed, a more painful occurrence, than the death of one we have injured without reparation.

Competition does a much more effective job than government at protecting consumers.

Truly great friends are hard to find, difficult to leave, and impossible to forget.
