Quote

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.

All great progress takes place when two sciences come together, and when their resemblance proclaims itself, despite the apparent disparity of their substance.
Henri Poincare
Image
Analyse data just so far as to obtain simplicity and no further.
Henri Poincare
Image
...the feeling of mathematical beauty, of the harmony of numbers and of forms, of geometric elegance. It is a genuinely aesthetic feeling, which all mathematicians know
Henri Poincare
Image
It is far better to foresee even without certainty than not to foresee at all.
Henri Poincare
Image
Mathematical discoveries, small or great are never born of spontaneous generation They always presuppose a soil seeded with preliminary knowledge and well prepared by labour, both conscious and subconscious.
Henri Poincare
Image
Later generations will regard Mengenlehre (set theory) as a disease from which one has recovered.
Henri Poincare
Image
Doubting everything and believing everything are two equally convenient solutions that guard us from having to think
Henri Poincare
Image
When the logician has resolved each demonstration into a host of elementary operations, all of them correct, he will not yet be in possession of the whole reality, that indefinable something that constitutes the unity ... Now pure logic cannot give us this view of the whole it is to intuition that we must look for it.
Henri Poincare
Image
Intuition is more important to discovery than logic.
Henri Poincare
Image
Zero is the number of objects that satisfy a condition that is never satisfied. But as never means in no case, I do not see that any progress has been made.
Henri Poincare
Image
The mathematical facts worthy of being studied are those which, by their analogy with other facts, are capable of leading us to the knowledge of a physical law. They reveal the kinship between other facts, long known, but wrongly believed to be strangers to one another.
Henri Poincare
Image
Ideas rose in clouds I felt them collide until pairs interlocked, so to speak, making a stable combination.
Henri Poincare
Image
When the physicists ask us for the solution of a problem, it is not drudgery that they impose on us, on the contrary, it is us who owe them thanks.
Henri Poincare
Image
What is a good definition? For the philosopher or the scientist, it is a definition which applies to all the objects to be defined, and applies only to them it is that which satisfies the rules of logic. But in education it is not that it is one that can be understood by the pupils.
Henri Poincare
Image
Point set topology is a disease from which the human race will soon recover.
Henri Poincare
Image
It is through science that we prove, but through intuition that we discover.
Henri Poincare
Image
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.
Henri Poincare
Image
Mathematics is the art of giving the same name to different things.
Henri Poincare
Image
Mathematicians do not study objects, but the relations between objects.
Henri Poincare
Image
It is the simple hypotheses of which one must be most wary because these are the ones that have the most chances of passing unnoticed.
