Quotes about science

Religion and science have always been matters of faith in something. It is the same something. You are yourself what you call a man of science, so I talk of science to you.

The progress of science depends much less upon theoretical considerations or systematic investigation than is commonly believed, but rather on the transmittal of reliable information, gained by chance or insight from one set of men to their successors. The nature of those who hunt after dark knowledge is to hoard it even unto death, or to transmit it so wrapped in disguise and beclouded with self-serving lies that it is of little value.

In each century since the beginning of the world wonderful things have been discovered. In the last century more amazing things were found out than in any century before. In this new century hundreds of things still more astounding will be brought to light. At first people refuse to believe that a strange new thing can be done, then they begin to hope it can be done, then they see it can be done—then it is done and all the world wonders why it was not done centuries ago. One of the new things people began to find out in the last century was that thoughts—just mere thoughts—are as powerful as electric batteries—as good for one as sunlight is, or as bad for one as poison. To let a sad thought or a bad one get into your mind is as dangerous as letting a scarlet fever germ get into your body. If you let it stay there after it has got in you may never get over it as long as you live.

Then something began pushing things up out of the soil and making things out of nothing. One day things weren’t there and another they were. I had never watched things before and it made me feel very curious. Scientific people are always curious and I am going to be scientific. I keep saying to myself, ’What is it? What is it?’ It’s something. It can’t be nothing!

Ifs and buts are the stuff of politics, Mr. Parkinson. As a scientist I am concerned with facts not with motives, suspicions, and airy-fairy nothingness.

This new quantum mechanics promised to explain all of chemistry. And though I felt an exuberance at this, I felt a certain threat, too. “Chemistry,” wrote Crookes, “will be established upon an entirely new basis…. We shall be set free from the need for experiment, knowing a priori what the result of each and every experiment must be.” I was not sure I liked the sound of this. Did this mean that chemists of the future (if they existed) would never actually need to handle a chemical; might never see the colors of vanadium salts, never smell a hydrogen selenide, never admire the form of a crystal; might live in a colorless, scentless, mathematical world? This, for me, seemed and awful prospect, for I, at least, needed to smell and touch and feel, to place myself, my senses, in the middle of the perceptual world.

The physicist may be satisfied when he has the mathematical scheme and knows how to use for the interpretation of the experiments. But he has to speak about his results also to non-physicists who will not be satisfied unless some explanation is given in plain language. Even for the physicist the description in plain language will be the criterion of the degree of understanding that has been reached.

The existing scientific concepts cover always only a very limited part of reality, and the other part that has not yet been understood is infinite.

We have to remember that what we observe is not nature herself, but nature exposed to our method of questioning.

There is an enormous difference between modern science and Greek philosophy, and that is just the empiristic attitude... Since the time of Galileo and Newton, modern science has been based upon a detailed study of nature and upon the postulate that only such statements should be made, as have been verified or at least can be verified by experiment. The idea that one can single out some events from nature by an experiment... to find out what is the constant law in the continuous change, did not occur to the Greek philosophers. Therefore, modern science has from its beginning stood on a much more modest, but at the same time much firmer, basis than ancient philosophy. Therefore, the statements of modern physics are in some way meant much more seriously than the statements of Greek philosophy.

[E]ven in the most precise part of science, in mathematics, we cannot avoid using concepts that involve contradictions. ...[I]t is well known that the concept of infinity leads to contradictions... but it would be practically impossible to construct... mathematics without this concept.

I remember discussions with Bohr which went through many hours till very late at night and ended almost in despair; and when at the end of the discussion I went alone for a walk in the neighbouring park I repeated to myself again and again the question: Can nature possibly be so absurd as it seemed to us in these atomic experiments?
