A man who dares to waste one hour of time has not discovered the value of life.

He was an ancient Greek philosopher and mathematician. He is one of the most famous mathematicians of all time, if not one of the most useful.

Pythagoras

As long as Man continues to be the ruthless destroyer of lower living beings, he will never know health or peace. For as long as men massacre animals, they will kill each other. Indeed, he who sows the seed of murder and pain cannot reap joy and love.

No one is free who has not obtained the empire of himself. No man is free who cannot command himself.

Educate the children and it won't be necessary to punish the men.

Do not say a little in many words, but a great deal in few!

There is geometry in the humming of the strings. There is music in the spacing of the spheres.

In anger we should refrain both from speech and action.

Rest satisfied with doing well, and leave others to talk of you as they please.

Rosalind Franklin

Science and everyday life cannot and should not be separated.

We wish to discuss a structure for the salt of deoxyribose nucleic acid. This structure has novel features which are of considerable biologic interest.

Science, for me, gives a partial explanation for life. In so far as it goes, it is based on fact, experience and experiment.

My method of thought and reasoning is influenced by a scientific training, if that were not so my scientific training will have been a waste and a failure.

I see no reason to believe that a creator of protoplasm or primeval matter, if such there be, has any reason to be interested in our insignificant race in a tiny corner of the universe, and still less in us, as still more insignificant individuals.

Again, I see no reason why the belief that we are insignificant or fortuitous should lessen our faith.

I agree that faith is essential to success in life but I do not accept your definition of faith.

What’s the use of doing all this work if we don't get some fun out of this?

What's the use of doing all this work if we don't get some fun out of this?

I would willingly go more primitive if it were necessary to preserve my freedom.

In my view, all that is necessary for faith is the belief that by doing our best we shall succeed in our aims: the improvement of mankind.

Your faith rests on the future of yourself and others as individuals, mine in the future and fate of our successors.

I maintain that faith in this world is perfectly possible without faith in another world.

Your theories are those which you and many other people find easiest and pleasantest to believe, but so far as I can see, they have no foundation other than they leaf to a pleasanter view of life (and an exaggerated idea of our own importance).

The results suggest a helical structure which must be very closely packed containing probably 2, 3 or 4 coaxial nucleic acid chains per helical unit and having the phosphate groups near the outside.

Traveling around in a little tin box isolates one from the people and the atmosphere of the place in a way that I have never experienced before.

You look at science (or at least talk of it) as some sort of demoralising invention of man, something apart from real life, and which must be cautiously guarded and kept separate from everyday existence. But science and everyday life cannot and should not be separated. Science, for me, gives a partial explanation for life. In so far as it goes, it is based on fact, experience and experiment.

Conclusion: Big helix in several chains, phosphates on outside, phosphate-phosphate inter-helical bonds disrupted by water. Phosphate links available to proteins.

He was a Danish physicist. He contributed so much to understanding atomic structure and quantum mechanics, receiving the Nobel Prize in Physics.

Niels Bohr

An expert is a person who has made all the mistakes that can be made in a very narrow field.

The opposite of a correct statement is a false statement. But the opposite of a profound truth may well be another profound truth.

Those who are not shocked when they first come across quantum theory cannot possibly have understood it.

Everything we call real is made of things that cannot be regarded as real.

How wonderful that we have met with a paradox. Now we have some hope of making progress.

No, no, you're not thinking; you're just being logical.

There are some things so serious that you have to laugh at them.

Never express yourself more clearly than you are able to think.

Stop telling God what to do with his dice.

The meaning of life consists in the fact that it makes no sense to say that life has no meaning.

Every great and deep difficulty bears in itself it’s own solution. It forces us to change our thinking in order to find it.

Prediction is very difficult, especially about the future.

Louis Pasteur

Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world. Science is the highest personification of the nation because that nation will remain the first which carries the furthest the works of thought and intelligence.

Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world.

There are no such things as applied sciences, only applications of science.

Fortune favors the prepared mind.

Do not let yourself be tainted with a barren skepticism.

Never will the doctrine of spontaneous generation recover from the mortal blow struck by this simple experiment.

Let me tell you the secret that has led me to my goal. My strength lies solely in my tenacity.

It is surmounting difficulties that makes heroes.

The universe is asymmetric and I am persuaded that life, as it is known to us, is a direct result of the asymmetry of the universe or of its indirect consequences. The universe is asymmetric.

The universe is asymmetric and I am persuaded that life, as it is known to us, is a direct result of the asymmetry of the universe or of its indirect consequences.

When I approach a child, he inspires in me two sentiments; tenderness for what he is, and respect for what he may become.

One must work; one must work. I have done what I could.

Science is the highest personification of the nation because that nation will remain the first which carries the furthest the works of thought and intelligence.

There does not exist a category of science to which one can give the name applied science. There are science and the applications of science, bound together as the fruit of the tree which bears it.

Nicolaus Copernicus

To know that we know what we know, and to know that we do not know what we do not know, that is true knowledge.

For I am not so enamoured of my own opinions that I disregard what others may think of them.

First of all, we must note that the universe is spherical.

I shall now recall to mind that the motion of the heavenly bodies is circular, since the motion appropriate to a sphere is rotation in a circle.

Yet if anyone believes that the earth rotates, surely he will hold that its motion is natural, not violent.

Accordingly, since nothing prevents the earth from moving, I suggest that we should now consider also whether several motions suit it, so that it can be regarded as one of the planets. For, it is not the center of all the revolutions.

Of all things visible, the highest is the heaven of the fixed stars.

The earth together with its surrounding waters must in fact have such a shape as its shadow reveals, for it eclipses the moon with the arc of a perfect circle.

I am aware that a philosopher's ideas are not subject to the judgment of ordinary persons, because it is his endeavour to seek the truth in all things, to the extent permitted to human reason by God.

Therefore, when I considered this carefully, the contempt which I had to fear because of the novelty and apparent absurdity of my view, nearly induced me to abandon utterly the work I had begun.

Moreover, since the sun remains stationary, whatever appears as a motion of the sun is really due rather to the motion of the earth.

Near the sun is the center of the universe.

More stars in the north are seen not to set, while in the south certain stars are no longer seen to rise.

Therefore, having obtained the opportunity from these sources, I too began to consider the mobility of the earth.

Those who know that the consensus of many centuries has sanctioned the conception that the earth remains at rest in the middle of the heavens as its center, would, I reflected, regard it as an insane pronouncement if I made the opposite assertion that the earth moves.

Finally we shall place the Sun himself at the center of the Universe.

At rest, however, in the middle of everything is the sun.

In so many and such important ways, then, do the planets bear witness to the earth's mobility.

The massive bulk of the earth does indeed shrink to insignificance in comparison with the size of the heavens.

Although all the good arts serve to draw man's mind away from vices and lead it toward better things, this function can be more fully performed by this art, which also provides extraordinary intellectual pleasure.

We regard it as a certainty that the earth, enclosed between poles, is bounded by a spherical surface.

So, influenced by these advisors and this hope, I have at length allowed my friends to publish the work, as they had long besought me to do.

Not a few other very eminent and scholarly men made the same request, urging that I should no longer through fear refuse to give out my work for the common benefit of students of Mathematics.

Pouring forth its seas everywhere, then, the ocean envelops the earth and fills its deeper chasms.

So far as hypotheses are concerned, let no one expect anything certain from astronomy, which cannot furnish it, lest he accept as the truth ideas conceived for another purpose, and depart from this study a greater fool than when he entered it.

I can easily conceive, most Holy Father, that as soon as some people learn that in this book which I have written concerning the revolutions of the heavenly bodies, I ascribe certain motions to the Earth, they will cry out at once that I and my theory should be rejected.

Mathematics is written for mathematicians.

Those things which I am saying now may be obscure, yet they will be made clearer in their proper place.

For it is the duty of an astronomer to compose the history of the celestial motions through careful and expert study.

Therefore, in the course of the work I have followed this plan: I describe in the first book all the positions of the orbits together with the movements which I ascribe to the Earth, in order that this book might contain, as it were, the general scheme of the universe.

The earth also is spherical, since it presses upon its center from every direction.

For a traveler going from any place toward the north, that pole of the daily rotation gradually climbs higher, while the opposite pole drops down an equal amount.

Therefore I would not have it unknown to Your Holiness, the the only thing which induced me to look for another way of reckoning the movements of the heavenly bodies was that I knew that mathematicians by no means agree in their investigation thereof.

Gregor Mendel

My scientific studies have afforded me great gratification; and I am convinced that it will not be long before the whole world acknowledges the results of my work.

The value and utility of any experiment are determined by the fitness of the material to the purpose for which it is used, and thus in the case before us it cannot be immaterial what plants are subjected to experiment and in what manner such experiment is conducted.

To live without experiencing some shame and blushes of admiration would surely be a wretched life.

Those traits that pass into hybrid association entirely or almost entirely unchanged, thus themselves representing the traits of the hybrid, are termed dominating and those that become latent in the association, recessive.

That no generally applicable law of the formulation and development of hybrids has yet been successfully formulated can hardly astonish anyone who is acquainted with the extent of the task and who can appreciate the difficulties with which experiments of this kind have to contend.

If A denotes one of the two constant traits, for example, the dominating one, a the recessive, and the Aa the hybrid form in which both are united, then the expression: gives the series for the progeny of plants hybrid in a pair of differing traits.

Marie Curie

Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less.

Life is not easy for any of us. But what of that? We must have perseverance and above all confidence in ourselves. We must believe that we are gifted for something and that this thing must be attained.

I was taught that the way of progress was neither swift nor easy.

One never notices what has been done; one can only see what remains to be done.

I have frequently been questioned, especially by women, of how I could reconcile family life with a scientific career. Well, it has not been easy.

There are sadistic scientists who hurry to hunt down errors instead of establishing the truth.

In science, we must be interested in things, not in persons.

Ada Lovelace

That brain of mine is something more than merely mortal; as time will show.

If you can’t give me poetry, can’t you give me poetical science?

I never am really satisfied that I understand anything; because, understand it well as I may, my comprehension can only be an infinitesimal fraction of all I want to understand about the many connections and relations which occur to me, how the matter in question was first thought of or arrived at…

Religion to me is science and science is religion.

Your best and wisest refuge from all troubles is in your science.

The science of operations, as derived from mathematics more especially, is a science of itself, and has its own abstract truth and value.

Imagination is the Discovering Faculty, pre-eminently. It is that which penetrates into the unseen worlds around us, the worlds of Science.

Mathematical science shows what is. It is the language of unseen relations between things. But to use and apply that language, we must be able to fully to appreciate, to feel, to seize the unseen, the unconscious.

As soon as I have got flying to perfection, I have got a scheme about a steam engine.

The more I study, the more insatiable do I feel my genius for it to be.

Those who have learned to walk on the threshold of the unknown worlds, by means of what are commonly termed par excellence the exact sciences, may then, with the fair white wings of imagination, hope to soar further into the unexplored amidst which we live.

Owing to some peculiarity in my nervous system, I have perception of some things, which no one else has; or at least very few, if any... I can throw rays from every quarter of the universe into one vast focus.

I find that nothing but very close and intense application to subjects of a scientific nature now seems at all to keep my imagination from running wild, or to stop up the void which seems to be left in my mind from a want of excitement.

A new, a vast, and a powerful language is developed for the future use of analysis, in which to wield its truths so that these may become of more speedy and accurate practical application for the purposes of mankind than the means hitherto in our possession have rendered possible.

I have my hopes, and very distinct ones, too, of one day getting cerebral phenomena such that I can put them into mathematical equations: in short, a law or laws for the mutual actions of the molecules of the brain (equivalent to the law of gravitation for the planetary & sideral world).

The Analytical Engine has no pretensions whatever to originate anything. It can do whatever we know how to order it to perform... But it is likely to exert an indirect and reciprocal influence on science itself.

I have got a scheme to make a thing in the form of a horse with a steam engine in the inside so contrived as to move an immense pair of wings, fixed on the outside of the horse, in such a manner as to carry it up into the air while a person sits on its back.

I believe myself to possess a most singular combination of qualities exactly fitted to make me pre-eminently a discoverer of the hidden realities of nature.

Those who incline to very strictly utilitarian views may perhaps feel that the peculiar powers of the Analytical Engine bear upon questions of abstract and speculative science rather than upon those involving everyday and ordinary human interests.

The ideas which led to the Analytical Engine occurred in a manner wholly independent of any that were connected with the Difference Engine. These ideas are indeed, in their own intrinsic nature, independent of the latter engine and might equally have occurred had it never existed nor even been thought of at all.

I am never so happy as when I am really engaged in good earnest, & it makes me must wonderfully cheerful and merry at other times, which is curious and very satisfactory.

I shall, in due time, be a Poet.

In the case of the Analytical Engine, we have undoubtedly to lay out a certain capital of analytical labour in one particular line, but this is in order that the engine may bring us in a much larger return in another line.

I am much pleased to find how very well I stand work and how my powers of attention & continued effort increase.

I think I am more determined than ever in my future plans, and I have quite made up my mind that nothing must be suffered to interfere with them. I intend to make such arrangements in town as will secure me a couple of hours daily (with very few exceptions) for my studies.

I wish to add my mite towards expounding & interpreting the Almighty, & his laws & works, for the most effective use of mankind; and certainly, I should feel it no small glory if I were enabled to be one of his most noted prophets (using this word in my own peculiar sense) in this world.

We may say most aptly that the Analytical Engine weaves algebraical patterns just as the Jacquard loom weaves flowers and leaves.

I was rather foolish in saying that I did not like arithmetic and to learn figures when I did - I was not thinking quite what I was about. The sums can be done better, if I tried, than they are.

The Analytical Engine does not occupy common ground with mere 'calculating machines.' It holds a position wholly its own, and the considerations it suggests are more interesting in their nature.

He was an ancient Greek scientist and philosopher. He is known to have been one of the first men to study Earth and space phenomena. 

Anaximander

Water is the principle of the universe.

Nature is eternal and does not age.

Things are full of Gods.

All beings are derived from other, older beings by successive transformations.

There are many worlds and many systems of Universes that exist all at the same time, all of them perishable.

The undefined is unborn and incorruptible, for that which begins necessarily has an end; and all corruption has a term.

Immortal and indestructible, it surrounds everything and destroys everything.

The undefined is divine, for it is immortal and imperishable.

The original principle of things is aperture. That is where they arise, that is where they later perish by reason of necessity.

Unlimited has no principle, for in such a case it would be limited.

Cesar Milstein

Back in 1962, when I had by accident become the supervisor of Roberto Celis in Argentina, it occurred to me that antibody diversity might arise from the joining by disulphide bridges of a variety of small polypeptides in combinatorial patterns.

My father was a Jewish immigrant who settled in Argentina and was left to his own devices at the age of 15. My mother was a teacher, herself the daughter of a poor immigrant family.

My thesis was on kinetics studies with the enzyme aldehyde dehydrogenase. When that was finished, I was granted a British Council Fellowship to work under the supervision of Malcolm Dixon.

I wasn't a particularly brilliant student, but on the other hand, I was very active in Student Union affairs and in student politics.

The study of the amino acid sequence around the disulphide bonds of the immunoglobulins was my own short-cut to the understanding of antibody diversity.

As we returned to Argentina, I started seriously to work towards a doctoral degree under the direction of Professor Stoppani, the Professor of Biochemistry at the Medical School.

When an animal is infected, either naturally or by experimental injection, with a bacterium, virus, or other foreign body, the animal recognises this as an invader and acts in such a way as to remove or destroy it.

What attracted me to immunology was that the whole thing seemed to revolve around a very simple experiment: take two different antibody molecules and compare their primary sequences.

Michael Faraday

Nothing is too wonderful to be true if it be consistent with the laws of nature.

There’s nothing quite as frightening as someone who knows they are right.

It is right that we should stand by and act on our principles; but not right to hold them in obstinate blindness, or retain them when proved to be erroneous.

A man who is certain he is right is almost sure to be wrong.

Shall we educate ourselves in what is known, and then casting away all we have acquired, turn to ignorance for aid to guide us among the unknown?
