It's incredible when I'm out in these towns. I have people telling me they were waiting for hours just to meet me and get my autograph. I feel so guilty. I always feel like I have to give them more than just Kato Kaelin.

I'm a young guy called 'commutative ring', but I was originally 'the ring of continuous functions on a compact Hausdorff space'. Now I am an algebraic object, so I must say goodbye to my home village, the space, but I will always keep it in my heart as a set of maximal ideals.

Quadratic reciprocity is the song of love in the land of prime numbers.

It never happens that, when we go home and open the refrigerator, we see all infinitely many prime numbers there.
