You cannot solve a problem from the same consciousness that created it. You must learn to see the world anew.
Our death is not an end if we can live on in our children and the younger generation. For they are us, our bodies are only wilted leaves on the tree of life.
All these primary impulses, not easily described in words, are the springs of man's actions.
I am a deeply religious nonbeliever - this is a somewhat new kind of religion.
Many of the things you can count, don't count. Many of the things you can't count, really count.
I sometimes ask myself how it came about that I was the one to develop the theory of relativity. The reason, I think, is that a normal adult never stops to think about problems of space and time. These are things which he has thought about as a child. But my intellectual development was retarded, as a result of which I began to wonder about space and time only when I had already grown up.
That deep emotional conviction of the presence of a superior reasoning power, which is revealed in the incomprehensible universe, forms my idea of God.
Memory is deceptive because it is colored by today's events.
Do not worry about your problems with mathematics, I assure you mine are far greater.
The minority, the ruling class at present, has the schools and press, usually the Church as well, under its thumb. This enables it to organize and sway the emotions of the masses, and make its tool of them.
Look deep into nature, and then you will understand everything better.
The highest principles for our aspirations and judgements are given to us in the Jewish-Christian religious tradition. It is a very high goal which, with our weak powers, we can reach only very inadequately, but which gives a sure foundation to our aspira
The difference between genius and stupidity is genius has its limits.
Possessions, outward success, publicity, luxury -- to me these have always been contemptible. I assume that a simple and unassuming manner of life is best for everyone, best for both the body and the mind.
A person starts to live when he can live outside himself.
My religion consists of a humble admiration of the illimitable superior spirit who reveals himself in the slight details we are able to perceive with our frail and feeble mind.
Formal symbolic representation of qualitative entities is doomed to its rightful place of minor significance in a world where flowers and beautiful women abound.
Nothing that I can do will change the structure of the universe. But maybe, by raising my voice I can help the greatest of all causes - goodwill among men and peace on earth.
Some recent work by E. Fermi and L. Szilard, which has been communicated to me in manuscript, leads me to expect that the element uranium may be turned into a new and important source of energy in the immediate future. Certain aspects of the situation which has arisen seem to call for watchfulness and, if necessary, quick action on the part of the Administration. This new phenomena would also lead to the construction of bombs.... A single bomb of this type, carried by boat and exploded in a port, might very well destroy the whole port, together with some of the surrounding territory. However, such bombs might very well prove to be too heavy for transportation by air.
Out of the multitude of our sense experiences we take, mentally and arbitrarily, certain repeatedly occurring complexes of sense impression (partly in conjunction with sense impressions which are interpreted as signs for sense experiences of others), and we attribute to them a meaning the meaning of the bodily object.
Nor do I take into account a danger of starting a chain reaction of a scope great enough to destroy part or all of the planet...But it is not necessary to imagine the earth being destroyed like a nova by a stellar explosion to understand vividly the growing scope of atomic war and to recognize that unless another war is prevented it is likely to bring destruction on a scale never before held possible, and even now hardly conceived, and that little civilization would survive it.
The only source of knowledge is experience.
The most powerful force in the universe is compound interest.
What guided Einstein was that, in his mid-twenties, he found the unknown intriguing. He felt compelled to comprehend what might have been intended for our universe by The Old One (as he referred to his notion of God). We are in the position, ... of a little child entering a huge library, whose walls are covered to the ceiling with books in many different languages. The child knows that someone must have written those books. It does not know who or how. It does not understand the languages in which they are written. The child notes a definite plan in the arrangement of the books, a mysterious order, which it does not comprehend but only dimly suspects.
Whoever is careless with the truth in small matters cannot be trusted with important matters.
Your imagination is your preview of life's coming attractions.
You can't blame gravity for falling in love.
If we knew what we were doing it wouldn't be research.
How strange is the lot of us mortals Each of us is here for a brief sojournfor what purpose we know not, though sometimes sense it. But we know from daily life that we exist for other people first of all for whose smiles and well-being our own happiness depends
Any power must be an enemy of mankind which enslaves the individual by terror and force, whether it arises under the Fascist or the Communist flag. All that is valuable in human society depends upon the opportunity for development accorded to the ind
