When you can measure what you are speaking about, and express it in numbers, you know something about it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind; it may be the beginning of knowledge, but you have...
If the hand be held between the discharge-tube and the screen, the darker shadow of the bones is seen within the slightly dark shadow-image of the hand itself... For brevity's sake I shall use the expression 'rays'; and to distinguish them from other...
Since we can produce all types of light by means of hot bodies, we can ascribe, to the radiation in thermal equilibrium with hot bodies, the temperature of these bodies, and thus every radiation, even that issuing from a phosphorescent body, has a ce...
I do not mean, of course, that we can always accurately express our conscious thoughts with Proustian accuracy. Consciousness overflows language: we perceive vastly more than we can describe.
The logical feebleness of science is not sufficiently borne in mind. It keeps down the weed of superstition, not by logic but by slowly rendering the mental soil unfit for its cultivation.
It’s very dangerous to invent something in our times; ostentatious men of the other world, who are hostile to innovations, roam about angrily. To live in peace, one has to stay away from innovations and new ideas. Innovations, like trees, attract t...
Many ritually abusive cults deliberately divide the personality system down the middle of the head, making sure that there is no communication between the two sides. “Left side" parts might be instructed to speak to no one other than the perpetrato...
When we look out into space, we're looking back in time; the light from a galaxy a billion light-years away, for instance, will take a billion years to reach us. It's an amazing thing. The history is there for us to see. It's not mushed up like the g...
To stand by yourself -- that was also part of dignity. That way, a person could get through a public flaying with dignity. Galileo. Luther. Even somebody who admitted his guilt and resisted the temptation to deny it. Something politicians couldn't do...
An honest man, armed with all the knowledge available to us now, could only state that in some sense, the origin of life appears at the moment to be almost a miracle, so many are the conditions which would have had to have been satisfied to get it go...
People tend to think that mathematicians always work in sterile conditions, sitting around and staring at the screen of a computer, or at a ceiling, in a pristine office. But in fact, some of the best ideas come when you least expect them, possibly t...
The progress of science requires the growth of understanding in both directions, downward from the whole to the parts and upward from the parts to the whole. A reductionist philosophy, arbitrarily proclaiming that the growth of understanding must go ...
What has been done is little—scarcely a beginning; yet it is much in comparison with the total blank of a century past. And our knowledge will, we are easily persuaded, appear in turn the merest ignorance to those who come after us.
The gramophone record, the musical thought, the score, the waves of sound, all stand to one another in that pictorial internal relation, which holds between language and the world. To all of them the logical structure is common. (Like the two youths,...
The nineteenth century will ever be known as the one in which the influences of science were first fully realised in civilised communities; the scientific progress was so gigantic that it seems rash to predict that any of its successors can be more i...
We walked up and down in the snow, I on skis and she on foot ( said and proved that could get along just as fast that way), and gradually the idea took shape that this was no chipping or cracking of the nucleus but rather a process to be explained by...
La religion est une insulte à la dignité humaine. Que ce soit avec ou sans elle, il y aura toujours des gens bien qui font de bonnes choses, et des mauvais qui font de mauvaises choses. Mais pour que des gens bien agissent mal, il faut la religion.
It is a matter for considerable regret that , who cultivated the theory of numbers with so much success, did not leave us with the proofs of the theorems he discovered. In truth, Messrs and , who have not disdained this kind of research, have proved ...
I believe that you can, by taking some simple and inexpensive measures, lead a longer life and extend your years of well-being. My most important recommendation is that you take vitamins every day in optimum amounts to supplement the vitamins that yo...
Tell me the size of a mammal and I can tell you, to about 85 per cent level, pretty much everything about its physiology and life history, such as how long it is going to live, how many offspring it will have, the length of its aorta, how long it wil...
I did not come from an academic background. My father was a smart man, but he had a fifth-grade education. He and all his friends were plumbers. They were all born around 1905 in great poverty in New York City and had to go to work when they were 12 ...
