“Science appears to us with a very different aspect after we have found out that it is not in lecture rooms only, and by means of the electric light projected on a screen, that we may witness physical phenomena.”

Mathematicians may flatter themselves that they possess new ideas which mere human language is as yet unable to express.

Gases are distinguished from other forms of matter, not only by their power of indefinite expansion so as to fill any vessel, however large, and by the great effect heat has in dilating them, but by the uniformity and simplicity of the laws which regulate these changes.

In the heavens we discover [stars] by their light, and by their light alone … the sole evidence of the existence of these distant worlds … that each of them is built up of molecules of the same kinds we find on earth.

… that, in a few years, all great physical constants will have been approximately estimated, and that the only occupation which will be left to men of science will be to carry these measurements to another place of decimals.

All the mathematical sciences are founded on relations between physical laws and laws of numbers.

I have looked into most philosophical systems and I have seen that none will work without God.

The experimental investigation by which Ampere established the law of the mechanical action between electric currents is one of the most brilliant achievements in science. The whole, theory and experiment, seems as if it had leaped, full grown and full armed, from the brain of the ‘Newton of Electricity’.

In Science, it is when we take some interest in the great discoverers and their lives that it becomes endurable, and only when we begin to trace the development of ideas that it becomes fascinating.

But, we venture to say, they will find themselves very much enlightened during the process, and will even be doubtful whether the ideas as expressed in symbols had ever quite found their way out of the equations into their minds.

We define thermodynamics … as the investigation of the dynamical and thermal properties of bodies, deduced entirely from the first and second law of thermodynamics, without speculation as to the molecular constitution.

One of the chief peculiarities of this treatise is the doctrine that the true electric current, on which the electromagnetic phenomena depend, is not the same thing as the current of conduction, but that the time-variation of the electric displacement must [also] be taken into account.

But I should be very sorry if an interpretation founded on a most conjectural scientific hypothesis were to get fastened to the text in Genesis…

I have also a paper afloat, with an electromagnetic theory of light, which, till I am convinced to the contrary, I hold to be great guns.

Heat may be generated and destroyed by certain processes, and this shows that heat is not a substance.

Science is incompetent to reason upon the creation of matter itself out of nothing. We have reached the utmost limit of our thinking faculties when we have admitted that because matter cannot be eternal and self-existent it must have been created.

An Experiment, like every other event which takes place, is a natural phenomenon; but in a Scientific Experiment the circumstances are so arranged that the relations between a particular set of phenomena may be studied to the best advantage.

You know Mildred would never do anything wrong or foolish. I reflected a little sadly that this was only too true and hoped I did not appear too much that kind of person to others. Virtue is an excellent thing and we should all strive after it, but it can sometimes be a little depressing.

The minority can seldom resist. But from the absolute will of an entire people there is no appeal, no redemption, no refuge but treason.

Buddhas move freely through birth and death, appearing and disappearing at will.

Think not I am what I appear.

Nothing that isn’t a real crime makes a man appear so contemptible and little in the eyes of the world as inconsistency.

Return to the nothingness from which the mad hope and ridiculous fright of men dared call you forth to their misfortune. You only appeared as a torment for the human race.

When both body and mind are at peace, all things appear as they are: perfect, complete, lacking nothing.

The more you go, the more will the place please you, if it be worth your attention. Give heed to the appearance of the neighbourhood.
