I would have picked up the artificial heart and thrown it on the floor and walked out and said he's dead if the press had not been there.

The phenomena in these exhausted tubes reveal to physical science a new world-a world where matter may exist in a fourth state, where the corpuscular theory of light may be true, and where light does not always move in straight lines, but where we can never enter, and with which we must be content to observe and experiment from the outside.

To stop short in any research that bids fair to widen the gates of knowledge, to recoil from fear of difficulty or adverse criticism, is to bring reproach on science. There is nothing for the investigator to do but go straight on, 'to explore up and down, inch by inch, with the taper his reason;' to follow the light wherever it may lead, even should it at times resemble a will-o'-the-wisp.

Mock on, mock on, Voltaire, Rousseau! Mock on, mock on: 'Tis all in vain! You throw the sand against the wind, And the wind blows it back again. And every sand becomes a gem Reflected in the beams divine; Blown back they blind the mocking eye, But still in Israel's paths they shine. The atoms of Democritus And Newton's particles of light Are sands upon the Red Sea shore, Where Israel's tents do shine so bright.

Physics investigates the essential nature of the world, and biology describes a local bump. Psychology, human psychology, describes a bump on the bump.

In the animal world, on the other hand, the process of evolution is characterised by the progressive discrimination of the animal and vegetative functions, and a consequent differentiation of these two great provinces into their separate departments.

The science of genetics is in a transition period, becoming an exact science just as the chemistry in the times of Lavoisier, who made the balance an indispensable implement in chemical research.

This constitution we designate by the word genotype. The word is entirely independent of any hypothesis; it is fact, not hypothesis that different zygotes arising by fertilisation can thereby have different qualities, that, even under quite similar conditions of life, phenotypically diverse individuals can develop.

The first [quality] to be named must always be the power of attention, of giving one's whole mind to the patient without the interposition of anything of oneself. It sounds simple but only the very greatest doctors ever fully attain it. ... The second thing to be striven for is intuition. This sounds an impossibility, for who can control that small quiet monitor? But intuition is only interference from experience stored and not actively recalled. ... The last aptitude I shall mention that must be attained by the good physician is that of handling the sick man's mind.

The dispassionate intellect, the open mind, the unprejudiced observer, exist in an exact sense only in a sort of intellectualist folk-lore; states even approaching them cannot be reached without a moral and emotional effort most of us cannot or will not make.

There is one experiment which I always like to try, because it proves something whichever way it goes. A solution of iodine in water is shaken with bone-black, filtered and tested with starch paste. If the colorless solution does not turn the starch blue, the experiment shows how completely charcoal extracts iodine from aqueous solution. If the starch turns blue, the experiment shows that the solution, though apparently colorless, still contains iodine which can be detected by means of a sensitive starch test.

A good catchword can obscure analysis for fifty years.

Science tries to answer the question: "How?" How do cells act in the body? How do you design an airplane that will fly faster thansound? How is a molecule of insulin constructed? Religion, by contrast, tries to answer the question: "Why?" Why was man created? Why ought I to tell the truth? Why must there be sorrow or pain or death? Science attempts to analyze how things and people and animals behave; it has no concern whether this behavior is good or bad, is purposeful or not. But religion is precisely the quest for such answers: whether an act is right or wrong, good or bad, and why.

Every new discovery of science is a further 'revelation' of the order which God has built into His universe.

Science has great skills, great reasoning and great intelligence in combining effects. It knows HOW to do many things but it admittedly does not know the WHY of anything.

Even if you only want to write science fiction, you should also read mysteries, poetry, mainstream literature, history, biography, philosophy, and science.

Without Art, we should have no notion of the sacred; without Science, we should always worship false gods.

The true men of action in our time those who transform the world are not the politicians and statesmen but the scientists. Unfortunately poetry cannot celebrate them because their deeds are concerned with things, not persons, and are therefore speechless. When I find myself in the company of scientists, I feel like a shabby curate who has strayed by mistake into a drawing room full of dukes.

When he to whom one speaks does not understand, and he who speaks himself does not understand, that is Metaphysics.

Science, like art, religion, political theory, or psychoanalysis - is work that holds out the promise of philosophic understanding, excites in us the belief that we can 'make sense of it all.

I have no knowledge other than that gained through my own eyes.

And as for other men, who worked in tank-rooms full of steam, and in some of which there were open vats near the level of the floor, their peculiar trouble was that they fell into the vats; and when they were fished out, there was never enough of them left to be worth exhibiting,-sometimes they would be overlooked for days, till all but the bones of them had gone out into the world as Durham's Pure Leaf Lard! This contributed to the passing of the Pure Food Act of 1906.

For those [observations] that I made in Leipzig in my youth and up to my 21st year, I usually call childish and of doubtful value. Those that I took later until my 28th year [i.e., until 1574] I call juvenile and fairly serviceable. The third group, however, which I made at Uraniborg during approximately the last 21 years with the greatest care and with very accurate instruments at a more mature age, until I was fifty years of age, those I call the observations of my manhood, completely valid and absolutely certain, and this is my opinion of them.

Since the beginning of physics, symmetry considerations have provided us with an extremely powerful and useful tool in our effort to understand nature. Gradually they have become the backbone of our theoretical formulation of physical laws.

... the atlas is a manifold. This is a typical mathematician's use of the word "is", and should not be confused with the normal use.
