The only thing that bothers me about studying is my education.
The life of each individual has meaning only if it helps him to make other people's lives more beautiful and better. Life is sacred, that is, a supreme value to which all other values are subordinate.
No end can be so great as to justify unworthy means employed to achieve it.
Mathematical laws that have anything to do with the real world are unreliable; and the mathematical laws of trust have nothing to do with the real world.
Sometimes we pay more for what we get for free.
Common sense is a collection of prejudices acquired by the age of eighteen.
We don't just want to find out how nature is ordered (and how natural phenomena occur), but in order to achieve our seemingly utopian and daring goal we need to find out why nature is the way it is, and not otherwise. In this scientists find their greatest satisfaction.
The mathematician is capable of something, but not of what is desired to be obtained from him at a given moment.
Math is the perfect way to screw yourself up.
Our mathematical difficulties do not bother God. He integrates empirically.
Do not deify the intellect. He has strong muscles but no face.
There is no doubt that there is an important grain of truth in quantum mechanics... Although I do not believe that quantum mechanics is the starting point for finding the [future theoretical] basis, any more than it is possible to start from thermodynamics... to get to the basics of mechanics.
The theory cannot be demonstrated by experiments, however many there may be; but a single experiment is enough to disprove it.
No problem can be solved at the same level at which it came into being.
Not everything of value can be valued, and not everything that is valued has value.
I would not recommend forming a team of inventors, because it is difficult to identify a true inventor; I believe that a society of drones running away from work can result from such an attempt.
Before God we are all equally wise; or equally stupid.
A practical profession is generally a salvation for people like me: the academic career forces a young man to give unceasing scientific production, and only strong natures can resist the temptation to make superficial analysis.
Reality is largely an illusion, albeit a very persistent one.
Ever since the mathematicians took up the theory of relativity, I for one no longer understand it.
The most inconceivable thing in the world is that the world can be understood.
The most difficult and incomprehensible thing in the world is income tax.
The secret of creativity lies in the ability to hide your sources.
The strength of the mind cannot replace the finesse of the fingers.
There is an amazing opportunity to master mathematics without understanding its essence.
Only those who undertake absurd attempts can achieve the impossible.
Man is a part of a whole, a part limited in time and space, of the whole we call the Universe. He feels himself, together with his thoughts and feelings, as something separate from the whole world, which is an illusion, an optical lie. This illusion has become a prison for us, limiting us to the world of our own desires and attachment to a narrow circle of people dear to us. Our task is to break free from this prison, extending our domain to every living being, to the whole world in all its splendor. No one is capable of carrying such a task to completion, but the very attempts to achieve this goal are part of the liberation and grounding of inner confidence.
Man can find the meaning of life, no matter how short and dangerous it may be, only by devoting himself to society.
Man begins to live only when he succeeds in overcoming himself.
I never think about the future. He comes quite quickly.
