The atheistic idea is so nonsensical that I do not see how I can put it in words.
Lord Kelvin
Image
I have no satisfaction in formulas unless I feel their numerical magnitude.
Lord Kelvin

To measure is to know.
Lord Kelvin
Image
When you cannot measure, your knowledge is meager and unsatisfactory.
Lord Kelvin
Image
The more thoroughly I conduct scientific research, the more I believe that science excludes atheism.
Lord Kelvin
Image
The vortex theory [of the atom] is only a dream. Itself unproven, it can prove nothing, and any speculations founded upon it are mere dreams about dreams.
Lord Kelvin
Image
Science is bound, by the everlasting vow of honour, to face fearlessly every problem which can be fairly presented to it.

Heavier-than-air flying machines are impossible.
Lord Kelvin

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.
Lord Kelvin

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

Nothing can be more fatal to progress than a too confident reliance on mathematical symbols for the student is only too apt to take the easier course, and consider the formula not the fact as the physical reality.
Lord Kelvin
Image
You know only insofar as you can measure.
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.
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
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.
Lord Kelvin
Image
[Of the ether] it is no greater mystery at all events than the shoemakers' wax.
Lord Kelvin
Image
I believe that the more thoroughly science is studied, the further does it take us from anything comparable to atheism.
Lord Kelvin
Image
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.

Fourier is a mathematical poem.

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.
