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.

The more thoroughly I conduct scientific research, the more I believe that science excludes atheism.
Lord Kelvin
Image
You know only insofar as you can measure.
Lord Kelvin
Image
Mathematics is the only true metaphysics.
Lord Kelvin
Image
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
Image
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.

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

Heavier-than-air flying machines are impossible.
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
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 we can't express what we know in the form of numbers, we really don't know much about it.
Lord Kelvin
Image
If you study science deep enough and long enough, it will force you to believe in God.
Lord Kelvin
Image
We only know God in His works, but we are forced by science to admit and to believe with absolute confidence in a Directive Power-in an influence other than physical, or dynamical, or electrical forces.
Lord Kelvin

To live among friends is the primary essential of happiness.
Lord Kelvin
Image
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.
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
I have no satisfaction in formulas unless I feel their numerical magnitude.
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

To measure is to know.

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.
