It is by logic that we prove, but by intuition that we discover. To know how to criticize is good, to know how to create is better.

Mathematics is the art of giving the same name to different things.
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
Mathematicians do not study objects, but the relations between objects.
Henri Poincare
Image
Guessing before proving! Need I remind you that it is so that all important discoveries have been made?
Henri Poincare
Image
Doubting everything and believing everything are two equally convenient solutions that guard us from having to think
Henri Poincare

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.
Henri Poincare
Image
Logic sometimes makes monsters. For half a century we have seen a mass of bizarre functions which appear to be forced to resemble as little as possible honest functions which serve some purpose.
Henri Poincare

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.

Thus, be it understood, to demonstrate a theorem, it is neither necessary nor even advantageous to know what it means.
Henri Poincare

The mind uses its faculty for creativity only when experience forces it to do so.
Henri Poincare
Image
One geometry cannot be more true than another it can only be more convenient.
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
The aim of science is not things themselves, as the dogmatists in their simplicity imagine, but the relation between things.
Henri Poincare
Image
It is far better to foresee even without certainty than not to foresee at all.
Henri Poincare
Image
I entered an omnibus to go to some place or other. At that moment when I put my foot on the step the idea came to me, without anything in my former thoughts seeming to have paved the way for it, that the transformations I had used to define the Fuchsian functions were identical with non-Euclidean geometry.
Henri Poincare

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

Experiment is the sole source of truth. It alone can teach us something new it alone can give us certainty.
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.

Later generations will regard Mengenlehre (set theory) as a disease from which one has recovered.

Just as houses are made of stones, so is science made of facts.
