The study of electric oscillations is essential for the development of wireless telegraphy.

The propagation of electric waves is a continuous process, not an instantaneous one.

The experiments provide a clear demonstration of the finite velocity of electric action.

The ether is the medium through which all electromagnetic actions are transmitted.

The properties of the ether are still a mystery, but we are making progress in understanding them.

The experiments have confirmed the predictions of Maxwell's theory in every detail.

The existence of electromagnetic waves is a triumph for theoretical physics.

The study of electric waves will lead to new discoveries in other branches of physics.

The ether is not a mere hypothesis, but a necessary postulate for understanding electromagnetic phenomena.

The experiments have provided a solid foundation for the future development of electromagnetic theory.

The most direct, and in a sense the most important, problem which our conscious knowledge of nature should enable us to solve is the anticipation of future events, so that we may arrange our present affairs in accordance with such anticipation.

One cannot escape the feeling that these mathematical formulae have an independent existence and an intelligence of their own, that they are wiser than we are, wiser even than their discoverers, that we get more out of them than was originally put into them.

Maxwell's theory is Maxwell's system of equations.

I do not think that the radio waves I have discovered will have any practical application.

The rigour of science requires that we distinguish well the undraped figure of nature itself from the gay-coloured vesture with which we clothe it at our pleasure.

It is not in the nature of things for any one man to make a sudden, violent discovery; science goes step by step, and every man depends on the work of his predecessors.

The waves which we have here considered are not light waves, but they are of the same electromagnetic nature.

To the question 'What is Maxwell's theory?' I know of no shorter or more definite answer than the following:—Maxwell's theory is Maxwell's system of equations.

The consequences of the theory are the test of its truth.

We form for ourselves images or symbols of external objects; and the form which we give them is such that the necessary consequents of the images in thought are always the images of the necessary consequents in nature of the things pictured.
