A Quote by Lord Kelvin

If we can't express what we know in the form of numbers, we really don't know much about it. — © Lord Kelvin
If we can't express what we know in the form of numbers, we really don't know much about it.
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.
When you can measure what you are speaking about, and express it in numbers, you know something about it.
In physical science a first essential step in the direction of learning any subject is to find principles of numerical reckoning and practicable methods for measuring some quality connected with it. 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; it may be the beginning of knowledge, but you have scarcely in your thoughts advanced to the stage of science, whatever the matter may be.
I don't know why people don't want to talk about their numbers. I guess in a sense, there's a bit of performer nudity, a bit of ego nudity when you expose your numbers, I guess because someone's are higher or someone's are lower. I've never really talked about the numbers with anyone, so maybe I'm not supposed to.
I know a few CEOs who delegate the understanding of their financials and their business metrics to the CFO, and then stop worrying about all that 'numbers stuff.' Don't do that. You have to know your numbers inside and out - they are your life blood.
Even people that know Johnny Cash's music really well and know that he was married don't really know that much about June Carter. So finding out about her really helped to inform my performance and to bring her to the front in a way that she has never been before.
I've discovered that most critics themselves are cinematically illiterate. They don't really know much about movies. They don't know the history. They don't know the technology. They don't know anything. So for them to try to analyze it, they're lost.
I know melody. I know rhythm; I know bass guitar; I know the piano. I know everything about music that helps build the music that go along with creating the whole art form, you know what I'm saying?
I know something about the civilization of China, with my background, obviously, and I think I know something about American history. But that's about all. And I've traveled all over the world, and for a long time I didn't know very much about it, really.
Don't know much about history, don't know much biology, don't know much about a science book, don't know much about the French I took.
I look pretty nondescript. I don't go out of my way to... I don't express my personality with my clothes, with my car or my, you know, house. I express with my personality; so as far as what I wear - I don't really care about that.
The thing about film is it is a very precise form. You know if you have it and you know if you don't have it. There's not really a middle bit where you're like, "I think we kind of have that scene."
I don't really know anything about my dad. I don't really know too much about his background. He's Jamaican and Jamaicans are usually more athletic. You've seen Usain Bolt.
I think that happens for a lot of people, they have this idea that there's only one type of way to write poetry and that you have to have this information. You have to know about meter, you have to know about form, you have to know about iambic pentameter, and all of that.
I think I'm more grounded, you know, and I know what I want out of life and I'm, you know, my morals are really, you know, strong and I have major beliefs about certain things and I think that has helped me, you know, from being, you know, coming from a really small town.
It's a great battle, and it really is a battle, and there are people from all walks of life, you know, never judge anybody at the table: A man can be the greatest poker player and he might know all the numbers, but he might get beaten by a really savvy kid who works in a grocery store; and that's what's so great about this game.
