Mathematicians are born, not made.
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
If we wish to foresee the future of mathematics, our proper course is to study the history and present condition of the science.
Henri Poincare
Image
It is a misfortune for a science to be born too late when the means of observation have become too perfect. That is what is happening at this moment with respect to physical chemistry the founders are hampered in their general grasp by third and fourth decimal places.
Henri Poincare
Image
Guessing before proving! Need I remind you that it is so that all important discoveries have been made?
Henri Poincare
Image
Pure logic could never lead us to anything but tautologies it can create nothing new not from it alone can any science issue.
Henri Poincare
Image
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
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
If nature were not beautiful, it would not be worth knowing, and if nature were not worth knowing, life would not be worth living
Henri Poincare
Image
For a long time the objects that mathematicians dealt with were mostly ill-defined one believed one knew them, but one represented them with the senses and imagination but one had but a rough picture and not a precise idea on which reasoning could take hold.
Henri Poincare
Image
How is error possible in mathematics?
Henri Poincare
Image
Geometry is not true, it is advantageous.
Henri Poincare
Image
It may happen that small differences in the initial conditions produce very great ones in the final phenomena.
Henri Poincare
Image
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.
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
Point set topology is a disease from which the human race will soon recover.
Henri Poincare
Image
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
. . . by natural selection our mind has adapted itself to the conditions of the external world. It has adopted the geometry most advantageous to the species or, in other words, the most convenient. Geometry is not true, it is advantageous.
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
