Can you measure it? Can you express it in figures? Can you make a model of it? If not, your theory is apt to be based more upon imagination than upon knowledge.

Questions of personal priority, however interesting they may be to the persons concerned, sink into insignificance in the prospect of any gain of deeper insight into the secrets of nature.

The atheistic idea is so nonsensical that I do not see how I can put it in words.
Lord Kelvin

If you study science deep enough and long enough, it will force you to believe in God.

Suppose that you could mark the molecules in a glass of water then pour the contents of the glass into the ocean and stir the latter throughly so as to distribute the marked molecules uniformly throughout the seven seas if then you took a glass of water anywhere out of the ocean, you would find in it about a hundred of your marked molecules.

Accurate and minute measurement seems to the non-scientific imagination, a less lofty and dignified work than looking for something new. But nearly all the grandest discoveries of science have been but the rewards of accurate measurement and patient long-continued labour in the minute sifting of numerical results.

I believe that the more thoroughly science is studied, the further does it take us from anything comparable to atheism.

Vortices of pure energy can exist and, if my theories are right, can compose the bodily form of an intelligent species.
Lord Kelvin

There cannot be a greater mistake than that of looking superciliously upon practical applications of science. The life and soul of science is its practical application.

I have no satisfaction in formulas unless I feel their numerical magnitude.

Heavier-than-air flying machines are impossible.

Mathematics is the only true metaphysics.
Lord Kelvin

Symmetrical equations are good in their place, but ' vector ' is a useless survival, or offshoot from quaternions, and has never been of the slightest use to any creature.
Lord Kelvin
Image
Science is bound, by the everlasting vow of honour, to face fearlessly every problem which can be fairly presented to it.
Lord Kelvin
Image
I often say that when you can measure what you are speaking about, and express it in numbers, you know something about it but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind.
Lord Kelvin

To measure is to know.
Lord Kelvin

I can never satisfy myself until I can make a mechanical model of a thing. If I can make a mechanical model, I can understand it. As long as I cannot make a mechanical model all the way through I cannot understand.

Overwhelmingly strong proofs of intelligent and benevolent design lie around us... the atheistic idea is so nonsensical that I cannot put it into words.

When you can measure what you are speaking about, and express it in numbers, you know something about it.

When you cannot measure, your knowledge is meager and unsatisfactory.

I have not the smallest molecule of faith in aerial navigation other than ballooning, or of the expectation of good results from any of the trials we heard of. So you will understand that I would not care to be a member of the Aeronautical Society.
