A Quote by Werner Heisenberg

The solution of the difficulty is that the two mental pictures which experiment lead us to form - the one of the particles, the other of the waves - are both incomplete and have only the validity of analogies which are accurate only in limiting cases.

Both matter and radiation possess a remarkable duality of character, as they sometimes exhibit the properties of waves, at other times those of particles. Now it is obvious that a thing cannot be a form of wave motion and composed of particles at the same time - the two concepts are too different

Werner Heisenberg

It is seen that both matter and radiation possess a remarkable duality of character, as they sometimes exhibit the properties of waves, at other times those of particles. Now, it is obvious that a thing cannot be a form of wave motion and composed of particles at the same time - the two concepts are too different.

I believe that this nation can only heal from the wounds of racism if we all begin to love blackness. And by that I don't mean that we love only that which is best within us, but that we're also able to love that which is faltering, which is wounded, which is contradictory, incomplete.

There is one experiment which I always like to try, because it proves something whichever way it goes. A solution of iodine in water is shaken with bone-black, filtered and tested with starch paste. If the colorless solution does not turn the starch blue, the experiment shows how completely charcoal extracts iodine from aqueous solution. If the starch turns blue, the experiment shows that the solution, though apparently colorless, still contains iodine which can be detected by means of a sensitive starch test.

The moment we face it frankly we are driven to the conclusion that the community has a right to put a price on the right to live in it ... If people are fit to live, let them live under decent human conditions. If they are not fit to live, kill them in a decent human way. Is it any wonder that some of us are driven to prescribe the lethal chamber as the solution for the hard cases which are at present made the excuse for dragging all the other cases down to their level, and the only solution that will create a sense of full social responsibility in modern populations?

George Bernard Shaw

Science walks forward on two feet, namely theory and experiment. Sometimes it is one foot which is put forward first, sometimes the other, but continuous progress is only made by the use of both.

Robert Andrews Millikan

Wisdom is the only thing which can relieve us from the sway of the passions and the fear of danger, and which can teach us to bear the injuries of fortune itself with moderation, and which shows us all the ways which lead to tranquility and peace.

Marcus Tullius Cicero

Thinking in pictures is, therefore, only a very incomplete form of becoming conscious. In some way, too, it stands nearer to unconscious processes than does thinking in words, and it is unquestionably older than the latter both ontogenetically and phylogenetically.

Sigmund Freud

In other words the pictures are in a kind of relationship with each other which is touching only at points rather than pictures being illustrations of poems or poems extrapolations of the pictures.

Peter Porter

Perhaps I should say that in general there are three solutions to such a situation. I mean not only in Holland, but everywhere where there are minority groups: in America, in Vietnam with the Chinese. Everywhere there is the same problem. But there are fundamentally three, actually only two possible solutions. A possible solution is that the despised minority is able to establish its own state somewhere else. The other solution is a higher or lesser degree of assimilation. And the third possibility, which is not a solution at all, is the permanence of the tension and conflict over time.

Norbert Elias

The last level of metaphor in the Alice books is this: that life, viewed rationally and without illusion, appears to be a nonsense tale told by an idiot mathematician. At the heart of things science finds only a mad, never-ending quadrille of Mock Turtle Waves and Gryphon Particles. For a moment the waves and particles dance in grotesque, inconceivably complex patterns capable of reflecting on their own absurdity.

Martin Gardner

If men could learn from history, what lessons it might teach us. But passion and party blind our eyes, and the light which experience gives us is a lantern on the stern, which shines only on the waves behind us.

Samuel Taylor Coleridge

Pathology has made us acquainted with a great number of states in which the boundary lines between the ego and the external world become uncertain or in which they are actually drawn incorrectly. There are cases in which parts of a person's own body, even portions of his own mental life - his perceptions, thoughts and feelings -, appear alien to him and as not belonging to his ego; there are other cases in which he ascribes to the external world things that clearly originate in his own ego and that ought to be acknowledged by it.

Sigmund Freud

We are only the temporary custodians of the particles which we are made of. They will go on to lead a future existence in the enormous universe that made them

Stephen Hawking

I am fully assured, that no general method for the solution of questions in the theory of probabilities can be established which does not explicitly recognize, not only the special numerical bases of the science, but also those universal laws of thought which are the basis of all reasoning, and which, whatever they may be as to their essence, are at least mathematical as to their form.
