We should seek the greatest value of our action.
Opinions are very dangerous, because they aren't based on scientific studies.
Even when all is known, the care of a man is not yet complete, because eating alone will not keep a man well; he must also take exercise. For food and exercise, while possessing opposite qualities, yet work together to produce health.
In a certain sense I made a living for five or six years out of that one star [υ Sagittarii] and it is still a fascinating, not understood, star. It's the first star in which you could clearly demonstrate an enormous difference in chemical composition from the sun. It had almost no hydrogen. It was made largely of helium, and had much too much nitrogen and neon. It's still a mystery in many ways. . . But it was the first star ever analysed that had a different composition, and I started that area of spectroscopy in the late thirties.
One thing that makes the adventure of working in our field particularly rewarding, especially in attempting to improve the theory, is that. . . a chief criterion for the selection of a correct hypothesis. . . seems to be the criterion of beauty, simplicity, or elegance.
The difference between science and the fuzzy subjects is that science requires reasoning while those other subjects merely require scholarship.
For I am yearning to visit the limits of the all-nurturing Earth, and Oceans, from whom the gods are sprung.
Science offends the modesty of all real women. It makes them feel as though it were an attempt to peek under their skin--or, worseyet, under their dress and ornamentation!
Science is not the affirmation of a set of beliefs but a process of inquiry aimed at building a testable body of knowledge constantly open to rejection or confirmation. In science, knowledge is fluid and certainty fleeting. That is at the heart of its limitations. It is also its greatest strength.
The magnet's name the observing Grecians drew. From the magnetic region where it grew.
The point of mathematics is that in it we have always got rid of the particular instance, and even of any particular sorts of entities. So that for example, no mathematical truths apply merely to fish, or merely to stones, or merely to colours. So long as you are dealing with pure mathematics, you are in the realm of complete and absolute abstraction. . . . Mathematics is thought moving in the sphere of complete abstraction from any particular instance of what it is talking about.
No matter if the science is all phoney, there are collateral environmental benefits. . . . climate change [provides] the greatest chance to bring about justice and equality in the world.
It is surprising that people do not believe that there is imagination in science. It is a very interesting kind of imagination, unlike that of the artist. The great difficulty is in trying to imagine something that you have never seen, that is consistent in every detail with what has already been seen, and that is different from what has been thought of; furthermore, it must be definite and not a vague proposition. That is indeed difficult.
Religion is against women's rights and women's freedom. In all societies women are oppressed by all religions.
Our mind is so fortunately equipped, that it brings us the most important bases for our thoughts without our having the least knowledge of this work of elaboration. Only the results of it become unconscious.
Every good mathematician should also be a good chess player and vice versa.
Geoff Nelder's ARIA has the right stuff. He makes us ask the most important question in science fiction-the one about the true limits of personal responsibility.
We live in a society exquisitely dependent on science
Every science touches art at some points—every art has its scientific side; the worst man of science is he who is never an artist, and the worst artist is he who is never a man of science.
In the Middle Ages people believed that the earth was flat, for which they had at least the evidence of their senses: we believe it to be round, not because as many as 1 percent of us could give physical reasons for so quaint a belief, but because modern science has convinced us that nothing that is obvious is true, and that everything that is magical, improbable, extraordinary, gigantic, microscopic, heartless, or outrageous is scientific.
