Notable Quotations

"Nature abhors the vacuum tube."
- J.R. Pierce, Bell Labs engineer who coined the term 'transistor'

"About thirty years ago there was much talk that geologists ought only to observe and not to theorize; and I well remember someone saying that at this rate a man might as well go into a gravel pit and count the pebbles and describe their colours. How odd it is that anyone should not see that all observations must be for or against some view if it is to be of any service."
- Darwin to Fawcett, 1861

"I do not consider it, the Vestiges of Creation, published in 1844, a hasty generalization, but rather as an ingenious hypothesis, strongly supported by some facts and analogies, but which remains to be proved by more facts and the additional light which more research may throw upon the problem. It furnishes a subject for every observer of nature to attend to; every fact he observes will make either for or against it."
- Alfred Russel Wallace, 1845

"If I have seen further than others, it is by standing upon the shoulders of giants."

- Thomas Carlyle: Letter to Emerson, April 29, 1836.

"Logic is a systematic method of coming to the wrong conclusion with confidence. "
- Unknown

"This is one of the hardest lessons for humans to learn. We cannot admit that things might be neither good nor evil, neither cruel nor kind, but simply callous - indifferent to all suffering, lacking all purpose."
- Richard Dawkins

"A human being is part of a whole, called by us the "Universe,"
a part limited in time and space. He experiences himself,
his thoughts and feelings, as something separated from the rest
-a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest us. Our task must be to free ourselves from this prison by widening our circles of compassion to embrace all living creatures and the whole of nature in its beauty. "
- Albert Einstein (1879-1955)

- Freeman Dyson

"We have met the enemy and he is US."
- Pogo (Walt Kelley)

"I believe the proliferation of weapons of mass destruction presents the greatest threat that the world has ever known. We are finding more and more countries who are acquiring technology – not only missile technology – and are developing chemical weapons and biological weapons capabilities to be used in theater and also on a long range basis. So I think that is perhaps the greatest threat that any of us will face in the coming years. "
- Secretary of Defense William Cohen

"To infinity and beyond ..."
- Buzz Lightyear

"Imagination is more important than knowledge"

"As I wrote many years ago at the very beginning of the debate about computers, a computer is just a glorified pencil. Einstein once said ";my pencil is cleverer than I";. What he meant could perhaps be put thus: armed with a pencil, we can be more than twice as clever as we are without. Armed with a computer (a typical World 3 object), we can perhaps be more than a hundred times as clever as we are without; and with improving computers there need not be an upper limit to this."
- Karl Popper

"...

"If someone points out to you that your pet theory of the universe is in disagreement with Maxwell's equations - then so much the worse for Maxwell's equations.

But if your theory is found to be against the second law of thermodynamics I can give you no hope; there is nothing for it but to collapse in deepest humiliation." 
- Sir Arthur Eddington

"Humans are not the end result of predictable evolutionary progress, but rather a fortuitous cosmic afterthought, a tiny little twig on the enormously arborescent bush of life, which if replanted from seed, would almost surely not grow this twig again."
- Stephen Jay Gould

"Explaining is a difficult art. You can explain something so that your reader understands the words; and you can explain something so that the reader feels it in the marrow of his bones. To do the latter, it sometimes isn't enough to lay the evidence before the reader in a dispassionate way. You have to become an advocate and use the tricks of the advocate's trade."
- Richard Dawkins

"When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge of it is of a meager and unsatisfactory kind: it may be the beginning of knowledge, but you have scarcely, in your thoughts, advanced to the stage of science."
- William Thomson, Lord Kelvin of Largs (1824-1907)

"We should take comfort in two conjoined features of nature: first, that our world is incredibly strange and therefore supremely fascinating . . . second, that however bizarre and arcane our world might be, nature remains comprehensible to the human mind."

For as at a great distance of place, that which wee look at, appears dimme, and without distinction of the smaller parts; and as Voyces grow weak, and inarticulate: so also after great distance of time, our imagination of the Past is weak; and wee lose (for example) of Cities wee have seen, many particular Streets; and of Actions, many particular Circumstances. This decaying sense, when wee would express the thing it self, (I mean fancy it selfe) wee call Imagination, as I said before: But when we would express the decay, and signifie that the Sense is fading, old, and past, it is called Memory. So that Imagination and Memory are but one thing...

The former may be described as language proper, the latter as mathematics.
