博士は息子を、ルートと呼んだ。「どんな数字でも嫌がらずに自分の中にかくまってやる、実に寛大な記号、ルートだよ」

Soon after I began working for the Professor, I realized that he talked about numbers whenever he was unsure of what to say or do. Numbers were also his way of reaching out to the world. They were safe, a source of comfort.

As I headed down the library steps, I turned back to look. The mathematics stacks were as silent and empty as ever. Apparently no one suspected the riches hidden there.

Solving a problem for which you know there’s an answer is like climbing a mountain with a guide, along a trail someone else has laid. In mathematics, the truth is somewhere out there in a place no one knows, beyond all the beaten paths. And it’s not always at the top of the mountain. It might be in a crack on the smoothest cliff or somewhere deep in the valley.

there was no shame in admitting you didn't have the answer, it was a necessary step toward the truth. It was as important to teach us about the unknown or the unknowable as it was to teach us what had already been safely proven.

Eternal truths are ultimately invisible, and you won't find them in material things or natural phenomena, or even in human emotions. Mathematics, however, can illuminate them, can give them expression - in fact, nothing can prevent it from doing so.

His ironing seemed highly rational, with a constant speed that allowed him to get the best results, with the least effort; all the economy and elegance of his mathematical proofs performed right there on the ironing board. The Professor was definitely the best man for this job, we had to admit, since the tablecloth was made of delicate lace.
