Science is facts just as houses are made of stones, so is science made of facts but a pile of stones is not a house and a collection of facts is not necessarily science.
It is far better to foresee even without certainty than not to foresee at all.
If nature were not beautiful, it would not be worth knowing, and if nature were not worth knowing, life would not be worth living
Thought is only a flash between two long nights, but this flash is everything
In the old days when people invented a new function they had something useful in mind.
Mathematics is the art of giving the same name to different things.
A scientist worthy of his name, about all a mathematician, experiences in his work the same impression as an artist; his pleasure is as great and of the same nature.
If we knew exactly the laws of nature and the situation of the universe at the initial moment, we could predict exactly the situation of the same universe at a succeeding moment.
One would have to have completely forgotten the history of science so as to not remember that the desire to know nature has had the most constant and the happiest influence on the development of mathematics.
The scientist does not study nature because it is useful; he studies it because he delights in it, and he delights in it because it is beautiful.
The mind uses its faculty for creativity only when experience forces it to do so.
It is the harmony of the diverse parts, their symmetry, their happy balance; in a word it is all that introduces order, all that gives unity, that permits us to see clearly and to comprehend at once both the ensemble and the details.
The Scientist must set in order. Science is built up with facts, as a house is with stones. But a collection of facts is no more a science than a heap of stones is a house.
It is through science that we prove, but through intuition that we discover.
Just as houses are made of stones, so is science made of facts.
