Everyone knows that in mathematics, beauty is the highest desideratum. But the few attempts to explain what’s meant by “mathematical beauty” have been feeble and unconvincing. Gian-Carlo has a new answer. “Beauty in mathematics is enlightenment.” When we are enlightened, we think, “How beautiful.” This insight is both enlightening and beautiful!
Reuben Hersh, en un prefacio a Indiscrete Thoughts (G.C. Rota)
Yo agregaría que, en mi experiencia, vale el recíproco. Cuando nos parece que no entendemos nada, pensamos “esto es horrendo”.
