I believe that at the end of the century the use of words and general educated opinion will have altered so much that one will be able to speak of machines thinking without expecting to...

Might one not say that in the chance combination of nature’s production, since only those endowed with certain relations of suitability could survive, it is no cause for wonder that this suitability is found in...

Upon this first, and in one sense this sole, rule of reason, that in order to learn you must desire to learn, and in so desiring not be satisfied with what you already incline to...

… our ‘Physick’ and ‘Anatomy’ have embraced such infinite varieties of being, have laid open such new worlds in time and space, have grappled, not unsuccessfully, with such complex problems, that the eyes of Vesalius...

Energetically speaking, antimatter is the mirror image of matter, so the two instantly cancel each other out if they come in contact.Keeping antimatter isolated from matter is a challenge, of course, because everything on earth...

Radio Wave Sickness and Electromagnetic Hypersensitivity are easily preventable and one can only wonder how much longer the insanity of modern governments is going to be allowed to continue in this area.

Life off Earth is in two important respects not at all unworldly: you can choose to focus on the surprises and pleasures, or the frustrations. And you can choose to appreciate the smallest scraps of...

For a God that created everything, it is mystifying why he created so much competition.

As an anonymous wit is supposed to have put it: “Hydrogen is a light, odorless gas which, given enough time, changes into people.

Mathematics is not arithmetic. Though mathematics may have arisen from the practices of counting and measuring it really deals with logical reasoning in which theorems—general and specific statements—can be deduced from the starting assumptions. It...

Our friend Dirac has a creed; and the main tenet of that creed is: There is no God, and Dirac is his prophet.

(T)he increase of known truths stimulates the investigation, establishment, and growth of the arts.

A number of years ago, when I was a freshly-appointed instructor, I met, for the first time, a certain eminent historian of science. At the time I could only regard him with tolerant condescension.I was...

Humanity is a biological species, living in a biological environment, because like all species, we are exquisitely adapted in everything: from our behavior, to our genetics, to our physiology, to that particular environment in which...

A curious aspect of the theory of evolution is that everybody thinks he understands it.

String theory is an attempt at a deeper description of nature by thinking of an elementary particle not as a little point but as a little loop of vibrating string.

Making mathematics accessible to the educated layman, while keeping high scientific standards, has always been considered a treacherous navigation between the Scylla of professional contempt and the Charybdis of public misunderstanding.

The Creator has – I say it in all reverence – drawn a myriad red herrings across the track, but the true scientist refuses to be baffled by superficial appearances in detecting the secrets of...

I do not believe that the present flowering of science is due in the least to a real appreciation of the beauty and intellectual discipline of the subject. It is due simply to the fact...

It took less than an hour to make the atoms, a few hundred million years to make the stars and planets, but five billion years to make man!

One of, if not the only, driving motive that prompts the majority to think that science cannot explain everything and therefore we need to believe in God and religion is simply laziness and inability to...

Science cannot stop while ethics catches up … and nobody should expect scientists to do all the thinking for the country.

I want to meddle with an Olympic medal made of silver metal. I want to alchemize it into gold, and use a mixture of science and mysticism to transform losing into winning.

We are the lucky ones for we shall die, as there is an infinite number of possible forms of DNA all but a few billions of which will never burst into consciousness.

The laboratory evidence that carbohydrate-rich diets can cause the body to reain water and so raise blood pressure, just as salt consumption is supposed to do, dates back well over a century

If it was the warmth of the sun, and not its light, that produced this operation, it would follow, that, by warming the water near the fire about as much as it would have been...

Olası olmayanın gerçekleşmesi, olasılığın sınırları içindedir.

One of the most striking results of modern investigation has been the way in which several different and quite independent lines of evidence indicate that a very great event occurred about two thousand million years...

State sponsored medicine and science can function as ideology, inspiring blind commitment, fanatical defensiveness and denial, particularly of outcomes inconsistent with the preferred explanatory model. The social etiology of compromised health, insists on an understanding...

There is no problem more difficult to solve than that created by ourselves.

Lastly, and doubtless always, but particularly at the end of the last century, certain scholars considered that since the appearances on our scale were finally the only important ones for us, there was no point...
