Human life is a voyage on a sea of meaning, not a net of information.
Gregory Benford
Words can be meaningless. If they are used in such a way that no sharp conclusions can be drawn.
Richard Feynman
No Self stands alone. Behind it stretches an immense chain of physical and - as a special class within the whole - mental events, to which it belongs as a reacting member and which it carries on. Through the condition at any moment of its somatic, especially its cerebral system, and through education, and tradition, by word, by writing, by monument, by manners, by a way of life, by a newly shaped environment... by so much that a thousand words would not exhaust it, by all that, I say, the Self is not so much linked with what happened to its ancestors, it is not so much the product, and merely the product, of all that, but rather, in the strictest sense of the word, the SAME THING as all that: the strict, direct continuation of it, just as the Self aged fifty is the continuation of the Self aged forty.
Erwin Schrödinger
If you want to live a happy life, tie it to a goal, not to people or things.
Albert Einstein
Science is a field which grows continuously with ever expanding frontiers. Further, it is truly international in scope. Any particular advance has been preceded by the contributions of those from many lands who have set firm foundations for further developments. The Nobel awards should be regarded as giving recognition to this general scientific progress as well as to the individuals involved.Further, science is a collaborative effort. The combined results of several people working together is often much more effective than could be that of an individual scientist working alone.
John Bardeen
Great spirits have always encountered violent opposition from mediocre minds.
Albert Einstein
How was I able to live alone before, my little everything? Without you I lack self-confidence, passion for work, and enjoyment of life--in short, without you, my life is no life.[Written to his wife, Mileva]
Albert Einstein
In any case, there was only one tunnel, dark and lonely, mine, the tunnel in which I had spent my childhood, my youth, my whole life. And in one of those transparent lengths of the stone wall I had seen this girl and had gullibly believed that she was traveling another tunnel parallel to mine, when in reality she belonged to the broad world, to the world without confines of those who do not live in tunnels; and perhaps she had peeped into one of my strange windows out of curiosity and had caught a glimpse of my doomed loneliness, or her fancy had been intrigued by the mute language, the clue of my painting.And then, while I advanced always along my corridor, she lived her normal life outside, the exciting life of those people who live outside, that strange, absurd life in which there are dances and parties and gaiety and frivolity. And it happened at times that when I walked by one of my windows she was waiting for me, silent and longing (why was she waiting for me? why silent and longing?); but other times she did not get there on time, or she forgot about this poor creature hemmed in, and then I, with my face pressed against the glass wall, could see her in the distance, smiling or dancing carefree, or, what was worse, I could not see her at all and I imagined her in inaccessible or vile places. And then I felt my destiny a far lonelier one than I had imagined.
Ernesto Sabato
By now he had learned. Choices are made in brief seconds and paid for in the time that remains.
Paolo Giordano
The tragedy of this world is that everyone is alone. For a life in the past cannot be shared with the present.
Alan Lightman
...finally her hands, so light, holding his head still and catching all his thoughts and imprisoning them there, in the space that no longer existed between them.
Paolo Giordano
I happen to know this, and I happen to know that, and maybe I know that;and I work everything out from there. Tomorrow I may forgot that this is true, but remember that something else is true, so I can reconstruct it all again. I am never quite sure of where I am supposed to begin or where I am supposed to end. I just remember enough all the time so that as the memory fades and some of the pieces fall out I can put the thing back together again every day.
Richard Feynman
We experience ourselves our thoughts and feelings as something separate from the rest. A kind of optical delusion of consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us.
Albert Einstein
As to rocket ships flying between America and Europe, I believe it is worth seriously trying for. Thirty years ago persons who were developing flying were laughed at as mad, and that scorn hindered aviation. Now we heap similar ridicule upon stratoplane or rocket ships for trans-Atlantic flights. (1933)[Predicting high-altitude jet aircraft for routine long-distance travel.]
Auguste Piccard
Kind words produce their images on men's souls.
Blaise Pascal
The invisible fuel for this healing process is our heartfelt compassion and loving presence and the sincerity of the collective intention that we bring to it.
William Keepin
The time has come for women and men to band together to jointly create gender harmony. We must gather in mixed group to plumb new depths of relational awareness, courageous truth-telling, compassionate listening, empathic sensitivity, and mutual healing.
William Keepin
One of the most convicting things I have recently come to realize about Jesus is that He was never, not once, in a hurry.
Mark Buchanan
During the youthful period of mankind's spiritual evolution human fantasy created gods in man's own image, who, by the operations of their will were supposed to determine, or at any rate to influence, the phenomenal world. Man sought to alter the disposition of these gods in his own favor by means of magic and prayer. The idea of God in the religions taught at present is a sublimation of that old concept of the gods. Its anthropomorphic character is shown, for instance, by the fact that men appeal to the Divine Being in prayers and plead for the fulfillment of their wishes. Nobody, certainly, will deny that the idea of the existence of an omnipotent, just, and omnibeneficent personal God is able to accord man solace, help, and guidance; also, by virtue of its simplicity it is accessible to the most undeveloped mind. But, on the other hand, there are decisive weaknesses attached to this idea in itself, which have been painfully felt since the beginning of history. That is, if this being is omnipotent, then every occurrence, including every human action, every human thought, and every human feeling and aspiration is also His work; how is it possible to think of holding men responsible for their deeds and thoughts before such an almighty Being? In giving out punishment and rewards He would to a certain extent be passing judgment on Himself. How can this be combined with the goodness and righteousness ascribed to Him?(Albert Einstein, Science, Philosophy, and Religion, A 1934 Symposium published by the Conference on Science, Philosophy and Religion in Their Relation to the Democratic Way of Life, Inc., New York, 1941; from Einstein's Out of My Later Years, Westport, Connecticut: Greenwood Press, 1970, pp. 26-27.)
Albert Einstein
Events, once happened, lose reality, alter with a glance, a storm, a night. In time, the past never happened. But who could know? Who could know that the past is not as solid as this instant…
Alan Lightman
Continents of memory had been lost.
Alan Lightman
Memory is deceptive because it is colored by today's events
Albert Einstein
Unassuming in manner, genial and kindly in his intercourse with his fellow-men, never showing impatience or irritation, devoid of personal ambition of the baser sort or of the slightest desire to exalt himself... In the minds of those who knew him, the greatness of his intellectual achievements will never overshadow the beauty and dignity of his life.[H.A. Burnstead's comments on the life of esteemed scientist J. Willard Gibbs]
Henry Andrews Bumstead
No self is of itself alone. It has a long chain of intellectual ancestors. The "I" is chained to ancestry by many factors… This is not mere allegory, but an eternal memory.
Erwin Schrödinger
What is this 'I'? If you analyse it closely you will, I think, find that it is just a little bit more than a collection of single data (experiences and memories), namely the canvas upon which they are collected. And you will, on close introspection, find that what you really mean by 'I' is that ground-stuff upon which they are collected. You may come to a distant country, lose sight of all your friends, may all but forget them; you acquire new friends, you share life with them as intensely as you ever did with your old ones. Less and less important will become the fact that, while living your new life, you still recollect the old one. 'The youth that was I', you may come to speak of him in the third person, indeed the protagonist of the novel you are reading is probably nearer to your heart, certainly more intensely alive and better known to you. Yet there has been no intermediate break, no death. And even if a skilled hypnotist succeeded in blotting out entirely all your earlier reminiscences, you would not find that he had killed you. In no case is there a loss of personal existence to deplore. Nor will there ever be.
Erwin Schrödinger
Memory is that element in our consciousness that connects the past with the present. If we had no memory, there would be only one moment of our life, the moment we call now, and we would never consciously recognize more than this single moment.
Gustaf Stromberg
The mature brain is a time capsule. History resides in its structure.
Julian B. Barbour
Some individuals have the courage to make it, even feel the need to do so; for them the quest is a necessity, not an option. Most people setting out on such journeys are never heard from again, but part of the romance of any field lies in keeping the dream alive, in not settling for what is familiar and comfortable.
Gino Segrè
If it isn't urgent, worry about it later
Albert Einstein
... though he [Michael Faraday] took no cities, he captivated all hearts.
John Tyndall
I think a power to do something is of value. Whether the result is a good thing or a bad thing depends on how it is used, but the power is a value.
Richard Feynman
I have no special talents. I am only passionately curious.
Albert Einstein
More importantly, our software worked. I don't just mean that it didn't bump, or that it performed according to the written specifications, or that it was efficient in producing reports. It really worked
Eliyahu M. Goldratt
When we first got married, we made a pact. It was this: In our life together, it was decided I would make all of the big decisions and my wife would make all of the little decisions. For fifty years, we have held true to that agreement. I believe that is the reason for the success in our marriage. However, the strange thing is that in fifty years, there hasn’t been one big decision.
Albert Einstein
But in practical affairs, particularly in politics, men are needed who combine human experience and interest in human relations with a knowledge of science and technology.
Max Born
t is generally recognized that women are better than men at languages, personal relations and multitasking, but less good at map-reading and spatial awareness. It is therefore not unreasonable to suppose that women might be less good at mathematics and physics. It is not politically correct to say such things....But it cannot be denied that there are differences between men and women. Of course, these are differences between the averages only. There are wide variations about the mean.
Stephen Hawking

Men are so inevitably mad that not to be mad would be to give a mad twist to madness.
Blaise Pascal
I gang my own gait and have never belonged to my country, my home, my friends, or even my immediate family, with my whole heart; in the face of all these ties I have never lost an obstinate sense of detachment, of the need for solitude — a feeling which increases with the years.
Albert Einstein
If someone were to propose that the planets go around the sun because all planet matter has a kind of tendency for movement, a kind of motility, let us call it an ‘oomph,’ this theory could explain a number of other phenomena as well. So this is a good theory, is it not? No. It is nowhere near as good as the proposition that the planets move around the sun under the influence of a central force which varies exactly inversely as the square of the distance from the center. The second theory is better because it is so specific; it is so obviously unlikely to be the result of chance. It is so definite that the barest error in the movement can show that it is wrong; but the planets could wobble all over the place, and, according to the first theory, you could say, ‘Well, that is the funny behavior of the ‘oomph.
Richard Feynman
If you had come to me a hundred years ago, do you think I should have dreamed of the telephone? Why, even now I cannot understand it! I use it every day, I transact half my correspondence by means of it, but I don’t understand it. Think of that little stretched disk of iron at the end of a wire repeating in your ear not only sounds, but words—not only words, but all the most delicate and elusive inflections and nuances of tone which separate one human voice from another!
William Crookes
…the imagination of nature is far, far greater than the imagination of man.
Richard Feynman
Keep in mind that imagination is at the heart of all innovation. Crush or constrain it and the fun will vanish.
Albert-László Barabási
The tragedy of this world is that no one is happy, whether stuck in a time of pain or of joy. The tragedy of this world is that everyone is alone. For a life in the past cannot be shared with the present. Each person who gets stuck in time gets stuck alone.
Alan Lightman
The catchers delight in the moment so frozen but soon discover that the nightingale expires, its clear flutelike song diminishes to silence, the trapped moment grows withered and without life.
Alan Lightman
But the essence of the process at its best is basically the same: women and men join together as equals, they get deeply honest with each other about their experiences, and through this process they heal past wounds, awaken to new realisations together, reach a place of reconciliation and forgiveness, and are thereby mutually transformed.
William Keepin
You can talk to me, too.""I do!""But you say so little.""Women talk a great deal to one another. All this gossip and such. I am not a woman.""What do you do when you have to command your men?" She inquired, exasperated. "Grunt?
Catherine Asaro
Light is the only connection we have with the Universe beyond our solar system, and the only connection our ancestors had with anything beyond Earth. Follow the light and we can journey from the confines of our planet to other worlds that orbit the Sun without ever dreaming of spacecraft. To look up is to look back in time, because the ancient beams of light are messengers from the Universe's distant past.
Brian Cox
The most striking impression was that of an overwhelming bright light. I had seen under similar conditions the explosion of a large amount—100 tons—of normal explosives in the April test, and I was flabbergasted by the new spectacle. We saw the whole sky flash with unbelievable brightness in spite of the very dark glasses we wore. Our eyes were accommodated to darkness, and thus even if the sudden light had been only normal daylight it would have appeared to us much brighter than usual, but we know from measurements that the flash of the bomb was many times brighter than the sun. In a fraction of a second, at our distance, one received enough light to produce a sunburn. I was near Fermi at the time of the explosion, but I do not remember what we said, if anything. I believe that for a moment I thought the explosion might set fire to the atmosphere and thus finish the earth, even though I knew that this was not possible.
Emilio Segrè
Suddenly, there was an enormous flash of light, the brightest light I have ever seen or that I think anyone has ever seen. It blasted; it pounced; it bored its way into you. It was a vision which was seen with more than the eye. It was seen to last forever. You would wish it would stop; altogether it lasted about two seconds.[Witnessing the first atomic bomb test explosion.]
Isidor Isaac Rabi
I was working with a Crookes tube covered by a shield of black cardboard. A piece of barium platino-cyanide paper lay on the bench there. I had been passing a current through the tube, and I noticed a peculiar black line across the paper. ...The effect was one which could only be produced in ordinary parlance by the passage of light. No light could come from the tube because the shield which covered it was impervious to any light known even that of the electric arc. ...I did not think I investigated. ...I assumed that the effect must have come from the tube since its character indicated that it could come from nowhere else. ... It seemed at first a new kind of invisible light. It was clearly something new something unrecorded. ...There is much to do, and I am busy, very
Wilhelm Conrad Röntgen
His [Faraday's] third great discovery is the Magnetization of Light, which I should liken to the Weisshorn among mountains-high, beautiful, and alone.
John Tyndall
The Theory of Relativity confers an absolute meaning on a magnitude which in classical theory has only a relative significance: the velocity of light. The velocity of light is to the Theory of Relativity as the elementary quantum of action is to the Quantum Theory: it is its absolute core.
Max Planck
Light brings us the news of the Universe.
William Henry Bragg
If the hand be held between the discharge-tube and the screen, the darker shadow of the bones is seen within the slightly dark shadow-image of the hand itself... For brevity's sake I shall use the expression 'rays'; and to distinguish them from others of this name I shall call them 'X-rays'.
Wilhelm Conrad Röntgen
First of all there is matter—and, remarkably enough, all matter is the same. The matter of which the stars are made is known to be the same as the matter on the earth...The same kinds of atoms appear to be in living creatures as in non-living creatures.
Richard Feynman
Truth is the offspring of silence and meditation. I keep the subject constantly before me and wait 'til the first dawnings open slowly, by little and little, into a full and clear light.
Isaac Newton
I received comments on how extraordinary it was that I could keep up speaking for exactly 45 minutes. Indeed, in an age of soundbites lasting some seconds and of quick quotes in the news, all those minutes do seem like an eternity, easy to get lost in. Yet, wait a moment. Television is not the only place where speeches are given. Some hundred thousand teachers teach every day. They all speak 45 minutes, more times a day. They have been doing this for years. Every teacher knows exactly when the time will be over and that by then his speech will need to come to a natural end. It is this tension that determines the success of a lesson. It is a sign of the times that we forget these daily achievements in education. A million students daily attend several ‘live’ lectures and this in secondary education alone. These are high ratings!
Robbert Dijkgraaf
It is my intent to beget a good understanding between the chymists and the mechanical philosophers who have hitherto been too little acquainted with one another's learning.
Robert Boyle
But willpower is necessary only where _ability_ to do is lacking. Learning ... is not the training of willpower but the acquisition of the skill to inhibit parasitic action and the ability to direct clear motivations as a result of self-knowledge. [Introduction]
