All my life, I have been fascinated by the big questions that face us, and have tried to find scientific answers to them.

Stephen Hawking

We used to be a source of fuel; we are increasingly becoming a sink. These supplies of foreign liquid fuel are no doubt vital to our industry, but our ever-increasing dependence upon them ought to arouse serious and timely reflection. The scientific utilisation, by liquefaction, pulverisation and other processes, or our vast and magnificent deposits of coal, constitutes a national object of prime importance.

Winston Churchill

It is my earnest desire that some of you should carry on this scientific work and keep for your ambition the determination to make a permanent contribution to science.

Where do correct ideas come from? Do they drop from the skies? No. Are they innate in the minds? No. They come from social practice, and from it alone; they come from three kinds of social practice, the struggle for production, the class struggle and scientific experiment.

It was love, she thought, love that never clutch its object; but, like the love which mathematicians bear their symbols, or poets their phrases, was meant to be spread over the world and become part of human gain. The world by all means should have shared it, could Mr Bankes have said why that woman pleased him so; why the sight of her reading a fairy tale to her boy had upon him precisely the same effect as the solution of a scientific problem.

I know that most men — not only those considered clever, but even those who are very clever and capable of understanding most difficult scientific, mathematical, or philosophic, problems — can seldom discern even the simplest and most obvious truth if it be such as obliges them to admit the falsity of conclusions they have formed, perhaps with much difficulty — conclusions of which they are proud, which they have taught to others, and on which they have built their lives.

His incredible untidiness, his addiction to music at strange hours, his occasional revolver practice within doors, his weird and often malodorous scientific experiments, and the atmosphere of violence and danger which hung around him made him the very worst tenant in London.

Arthur Conan Doyle

Supposing you got a crate of oranges that you opened, and you found all the top layer of oranges bad, you would not argue, "The underneath ones must be good, so as to redress the balance"; You would say, "Probably the whole lot is a bad consignment"; and that is really what a scientific person would say about the universe.

Bertrand Russell

For, the advantages which fashion values, are plants which thrive in very confined localities, in a few streets, namely. Out of this precinct, they go for nothing; are of no use in the farm, in the forest, in the market, in war, in the nuptial society, in the literary or scientific circle, at sea, in friendship, in the heaven of thought or virtue.

Ralph Waldo Emerson

Service of the people by sciences and arts will only exist when men live with the people and as the people live, and without presenting any claims will offer their scientific and artistic services, which the people will be free to accept or decline as they please.

In terms of doing things I take a fairly scientific approach to why things happen and how they happen. I don't know if there's a god or not, but I think religious principles are quite valid.

Just as we teach children to avoid being destroyed by motor cars if they can, so we should teach them to avoid being destroyed by cruel fanatics, and to this end we should seek to produce independence of mind, somewhat sceptical and wholly scientific, and to preserve, as far as possible, the instinctive joy of life that is natural to healthy children. This is the task of a liberal education: to give a sense of the value of things other than domination, to help create wise citizens of a free community, and through the combination of citizenship with liberty in individual creativeness to enable men to give to human life that splendour which some few have shown that it can achieve.

Bertrand Russell

The discovery of causal laws is the essence of science and therefore there can be no doubt that scientific men do right to look for them. If there is any region where there are no causal laws, that region is inaccessible to science. But the maxim [is] that mushroom gatherers should seek mushrooms.

Bertrand Russell

Every new discovery is assumed at once into the sum total of knowledge, and with that ceases in a sense to be a discovery; it dissolves into the whole and disappears, and one must have a trained scientific eye even to recognize it after that.

One thing only is needful: the knowledge of the simple and clear truth which finds place in every soul that is not stupefied by religious and scientific superstitions — the truth that for our life one law is valid — the law of love, which brings the highest happiness to every individual as well as to all mankind.

Scientific man is supposed to limit himself to his immediate surroundings. However if he should occasionally want to step forth as a poet, he certainly should not be prevented from doing so.

Johann Wolfgang von Goethe

Without denying the value of scientific endeavor, there is a striking absurdity in committing billions to reach the moon where no people live, while only a fraction of that amount is appropriated to service the densely populated slums.

Martin Luther King, Jr.

Science does not promise absolute truth, nor does it consider that such a thing necessarily exists. Science does not even promise that everything in the Universe is amenable to the scientific process.

The pursuit of knowledge is, I think, mainly actuated by love of power. And so are all advances in scientific technique. In politics, also, a reformer may have just as strong a love of power as a despot. It would be a complete mistake to decry love of power altogether as a motive. Whether you will be led by this motive to actions which are useful, or to actions which are pernicious, depends upon the social system, and upon your capacities.

Bertrand Russell

Even as Japanese responders continue to do heroic work, we know that the damage to the nuclear reactors in Fukushima Daiichi plant poses a substantial risk to people who are nearby. That is why yesterday, we called for an evacuation of American citizens who are within 50 miles of the plant. This decision was based upon a careful scientific evaluation and the guidelines that we would use to keep our citizens safe here in the United States, or anywhere in the world.

The ordinary scientific man is strictly a sentimentalist. He is a sentimentalist in this essential sense, that he is soaked and swept away by mere associations.

G. K. Chesterton

Our society is neither scientific nor splendid, but independent, hospitable, correct, and neighborly.

Thomas Jefferson

The content of scientific theory itself offers no moral foundation for the personal conduct of life.

Albert Einstein

I do not believe that science per se is an adequate source of happiness, nor do I think that my own scientific outlook has contributed very greatly to my own happiness, which I attribute to defecating twice a day with unfailing regularity.

Bertrand Russell

If scientific discovery has not been an unalloyed blessing, if it has conferred on mankind the power not only to create but also to annihilate, it has at the same time provided humanity with a supreme challenge and a supreme testing

John F. Kennedy
