Immediately I can picture her,hair wild,blue housecoat covered in flour,a wooden spoon in one hand,the pencil in the other,her mouth moving silently.My mother smiles and says,“One day I was cooking and watching baby Pauline,and I had a brilliant thought,but the stand was empty.One of the children must have taken the paper.So I just picked up the breadboard and wrote it all down on the back.It turned out to be a real breakthrough for solving the mathematical problem I was working on.”
This story—which happened before I was born—reminds me how extraordinary my mother was,and is also a gifted mathematician.I feel embarrassed that I complain about not having enough child-free time to work.Later,when my mother is in the bathroom,I go into her kitchen and turn over the breadboards.Sure enough,on the back of the smallest one,are some penciled marks I recognize as mathematics.Those symbols have traveled unaffected through fifty years,rooted in the soil of a cheap wooden breadboard,invisible（看不到的）exhibits at every meal.
