The French mathematician Jules Henri Poincaré (1854-1912) said:
The scientist does not study nature because it is useful, but because it captivates him, and captivates him because it is beautiful.
If nature were not beautiful, it would not be worth knowing, and if it was not worth knowing, it would not be worth living. Of course, I do not mean here the beauty that stimulates the senses, that of qualities and appearances; It is not that I despise it at all, but that it has nothing to do with science. I refer to the deepest beauty, which comes from the harmonious order of the parts and which can capture a pure intelligence.
