The Housekeeper and the Professor by Yoko Ogawa (Translated from the Japanese by Stephen Snyder)

A housekeeper is hired to take care of an old mathematics professor with a head injury. Due to a car accident in 1975, the professor’s memories stop in that year and any new memories are limited to 80-minutes. Once this period of time has passed, the new memories are replaced with other experiences that are 80-minutes long, in a process that is repeated endlessly. This lack of short-term memory, however, is compensated by the professor’s ability to maintain his mathematical knowledge, which he puts to constant use in the various math puzzle contests that he enters.

The professor’s sister-in-law explains this strange situation to the housekeeper before she begins her job. The sister then retreats to her house where she is no longer seen, leaving the housekeeper to take care of the professor – who lives in a neighbouring cottage – all by herself.

So each morning, as she arrives for work, the housekeeper must reintroduce herself to the professor, whose suit is filled with notes that remind him of important things, many of them mathematical, but others about new realities such as the presence of the housekeeper. From this unusual dynamic a beautiful friendship is born. The relationship becomes even stronger when the housekeeper’s son (who the professor calls “Root” because his flat head reminds him of the square root sign, a fact that he writes down in a note that is clipped onto his suit with a binder clip), begins to come to the cottage. The ensuing interactions between the three awaken a love of math in the housekeeper and her son, as they both come to see the beauty in numbers, and also the kind heart and soft nature of the professor.

In this lovely and touching novel, Yoko Ogawa paints a beautiful portrait filled with tenderness, true friendship and the wonder of mathematics. This book also declares that even in a world where memory is short (in this case, only 80-minutes long) humanity can still flourish, and friendship nurtured by the magic and wonder of numbers.
