Simplification of modes of proof is not merely an indication of advance in our knowledge of a subject, but is also the surest guarantee of readiness for farther progress.

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

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

Heavier-than-air flying machines are impossible.
Lord Kelvin
Image
To measure is to know.
Lord Kelvin
Image
When you cannot measure, your knowledge is meager and unsatisfactory.
Lord Kelvin
Image
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.

Mathematics is the only true metaphysics.

Fourier is a mathematical poem.
Lord Kelvin
Image
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
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.

The atheistic idea is so nonsensical that I do not see how I can put it in words.
Lord Kelvin
Image
[Of the ether] it is no greater mystery at all events than the shoemakers' wax.
Lord Kelvin
Image
When you can measure what you are speaking about, and express it in numbers, you know something about it.
Lord Kelvin
Image
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
Image
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
If you can not measure it, you can not improve it.
Lord Kelvin
Image
I have no satisfaction in formulas unless I feel their numerical magnitude.
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
You know only insofar as you can measure.
Lord Kelvin

If we can't express what we know in the form of numbers, we really don't know much about it.
