“ Let a drop of wine fall into a glass of water; whatever be the law that governs the internal movement of the liquid, we will soon see it tint itself uniformly pink and from that moment on, however we… Henri Poincare
“ 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. Henri Poincare
“ A very small cause which escapes our notice determines a considerable effect that we cannot fail to see, and then we say that the effect is due to chance. Henri Poincare
“ Science is built up of 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
“ 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. Henri Poincare
“ 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
“ Absolute space, that is to say, the mark to which it would be necessary to refer the earth to know whether it really moves, has no objective existence. Henri Poincare
“ 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
“ 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. Henri Poincare
“ Science is built of facts the way a house is built of bricks but an accumulation of facts is no more science than a pile of bricks is a house. Henri Poincare
“ 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 mathe… Henri Poincare
“ How is it that there are so many minds that are incapable of understanding mathematics? ... the skeleton of our understanding, ... and actually they are the majority. ... We have here a problem that i… Henri Poincare
“ Why is it that showers and even storms seem to come by chance, so that many people think it quite natural to pray for rain or fine weather, though they would consider it ridiculous to ask for an eclip… Henri Poincare
“ Consider now the Milky Way. Here also we see an innumerable dust, only the grains of this dust are no longer atoms but stars; these grains also move with great velocities, they act at a distance one u… Henri Poincare
“ 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
