Chapters 4-6Chapter Summaries & Analyses

Chapter 4 Summary

The Professor’s favorite topic is prime numbers, and the narrator and Root also grow to love the secrets they hold. The Professor inevitably repeats himself, but the narrator and Root make a serious agreement never to let him know it, both out of respect and to avoid confusing him.

One evening, the Professor asks them what they notice about the prime numbers between zero and 100. Root notices that two is the only even prime number, while the narrator sees that sometimes they come in “pairs,” like 17 and 19, which the Professor tells them are called twin primes. As the numbers get larger, both primes and twin primes because less frequent—because of that, we don’t know if twin primes are also infinite. The narrator marvels at the Professor’s willingness to admit when he doesn’t know something.

The Professor hates crowds, which is why he dislikes leaving the house: “There was something fundamentally incompatible […] between crushing, random crowds and pure mathematical beauty” (64). He doesn’t need silence, but he does require peace in his day-to-day life. He finds all sorts of things peaceful: completed mathematical proofs, the narrator’s dumpling-making process, etc.

On May 6, the narrator arrives to a leaky sink and a growing puddle in the house; moreover, the Professor seems to have more trouble than usual understanding who she is. Later, after Root arrives, she realizes that she’s run out of cooking oil, and she reluctantly leaves Root alone with the Professor while she buys more. While she’s out, Root tries to peel an apple and cuts himself; it isn’t a bad cut, but the Professor gets very upset. By the time the narrator returns, even though Root seems fine, she finds them on the floor together, the Professor wailing and inconsolable.

The narrator calls around and finds a doctor who is still open. The Professor hoists Root up onto his back and charges to the doctor’s office. While they wait for the doctor to examine Root, the Professor tries to discuss mathematics with the narrator, but his hand shakes, still rattled by the experience. Root emerges and announces that he’s okay. The three eat dinner at the emptiest restaurant nearby to avoid crowds. The Professor once again carries Root home piggyback.

As soon as the narrator and her son leave the Professor’s home, Root’s mood turns sour. The narrator tries to get him ready for bed, but he angrily resists and starts crying. He’s mad at her because she didn’t trust the Professor to watch Root while she was gone.

The next day, the Professor has forgotten all about the incident—the narrator helps him recopy his notes, and he wonders where all the blood came from. He’s surprised to hear about the accident, but happy to hear that he helped. 

Chapter 5 Summary

The Professor has other interesting talents besides his mathematical abilities. For example, he is able to reverse the syllables in a sentence and repeat them backwards instantly, simply by feeling the rhythm of the words. He’s surprised to learn that not everyone can do that. He’s happy that it pleases Root and the narrator, but he doesn’t understand what makes it special or interesting to them.

The Professor is also able to find the first sign of the evening star in the afternoon sky. At first, the narrator thinks he’s imagining things. Eventually she sees that he is always right, though—wherever he points to the evening star, it eventually appears for her, as well.

Root behaves himself around the Professor, but he continues to be upset with the narrator until she gives Root a heartfelt apology for not trusting the Professor. Root accepts, but he tells her that he’ll still never forget that it happened.

While straightening the shelves in the study one day, the narrator finds a cookie tin under a pile of books. She looks inside and finds a carefully packed tin of baseball cards, all Hanshin Tigers. The cards are organized by position, with a separate section devoted to Yutaka Enatsu; his cards are in thick plastic instead of normal cellophane protectors. Farther back in the shelves, she finds a stack of old notebooks filled with numbers. The narrator can’t understand them, but she’s nevertheless fascinated by the formulas.

The narrator buys three tickets to see the Tigers play against Hiroshima, as the Tigers only play nearby twice a season. She realizes that she’s been so focused on making ends meet that Root has hardly experienced anything. She thinks that a baseball game might be interesting for the Professor, who also had never been to one.

After she buys the tickets, though, Root reminds her that the Professor probably won’t want to go because he hates crowds. Moreover, they’re not sure how to prepare him for the game since he won’t remember anything prior to the day of the game. Above all, the Tigers the Professor remembers have all retired, including his favorite, Enatsu. Even so, Root is overjoyed for the opportunity to go to a game in person.

The day of the game is bright and sunny. They wait to tell the Professor about the game until they’re within the 80-minute window. When he asks about Enatsu, they concoct a story that Enatsu pitched too recently to play that day. Root is excited to go, so the Professor also agrees to go.

The narrator, speaking from her position in the future, notes that she and Root will never be sure if the Professor enjoyed the game—there was a lot going on, and it was nerve-wracking for him. However, there are many small, enjoyable moments. For example, the Professor is fascinated by one of the girls selling drinks and insists that they order from her nearly every time she comes by. For another, the Professor talks about numbers throughout the game, rattling off statistics to the amusement of one of the people sitting near them. He is so absorbed in the numbers that he doesn’t notice that so many of the players are unfamiliar to him.

In the final inning, one of the batters hits a foul ball that nearly hits Root. The Professor leaps up to shield him, remaining in place well after the ball has settled. The Professor finally settles back into place, murmuring to himself about statistics. The Tigers ultimately win the game, though the pitcher, Nakagomi, loses his no-hitter in the final inning. 

Chapter 6 Summary

It’s late when they return. Before the Professor falls asleep, he thanks them. Root is upset that Nakagomi blew the no-hitter, but the Professor tells him that Enatsu threw one in 1973 and won the game with a walk-off home run to boot.

As the Professor falls asleep, the narrator feels his head and realizes he has a fever. Unwilling to leave him sick and alone, she decides to stay with him. She briefly considers contacting his sister-in-law, but she decides against it due to the widow’s warnings. The narrator worries that she made a mistake in taking him to the game.

The next morning, Root leaves for school, but the Professor remains asleep. When he does wake up, the narrator tries to explain what’s happening and get him back to bed. She apologizes for the baseball game, but when he gets upset, she realizes she made a mistake by even mentioning it since he no longer remembers it. The Professor looks at the note reminding him about his memory and cries quietly. The narrator consoles him; eventually, he asks her questions about numbers again.

The narrator is afraid to take the Professor to a doctor, but after three days, his fever breaks on its own. However, after he recovers, the director of the narrator’s agency asks to speak to her. The Professor’s sister-in-law has complained about the fact that they spent the night with the Professor, so the director has decided to reassign her. The narrator pushes back, but the director tells her that it’s non-negotiable.

The narrator’s new employers are a couple who run a tax consulting service; the commute and hours are long, and the couple blurs the line between housekeeping duties and work for their business. Moreover, Root is once again on his own after school.

Leaving clients doesn’t usually bother the narrator, but it frustrates her that the Professor has no recollection of their time together. She finds herself distracted thinking about him. She hopes the widow will realize she’s the only person for that job, but she knows that plenty of other housekeepers could do a good job taking care of him.

After her dismissal, the narrator experiences a run of strange, bad luck. First, a woman robs her at a bus stop by simply walking up and demanding money; the narrator is surprised by how willingly she just handed over money to the stranger despite the absence of a threat. Later, while visiting her mother’s grave, she and Root find a dead, decomposing fawn. The day after the fawn, the narrator sees a newspaper article announcing that Root’s father had won a research prize; at first, she throws the article away, but then smoothes it out and places it in a box with the stump of Root’s umbilical cord.

Chapters 4-6 Analysis

Although the narrator mentions at the start of the novel that the Professor is a gifted educator, we see this more fully develop in this section as the Professor explains patterns within prime numbers. It’s important that the Professor is teaching not just Root, but also the narrator—the narrator is impressed by the Professor’s patience with Root, but throughout the novel we also see his patience with the narrator, as well as the impact it has on her. The Professor instills a newfound love for mathematics in the narrator, someone who never received a higher education and always believed she hated math.

Key to this is the Professor’s open-mindedness and lack of pretense. Despite his brilliance, he doesn’t look down on Root or the narrator—he simply loves numbers and wishes to share that love with others, discussing both high-level and basic mathematics with wonder and joy. Moreover, the Professor is humble—the narrator is impressed by his ability to admit when he doesn’t know something mathematical, and he’s happy to admit his many shortcomings outside of mathematics, too. In his mind, they all have something they can learn, but they can only do so if they admit they don’t know it, first.

The baseball game brings with it internal and external conflicts. First is the narrator’s decision to buy the tickets, which she does without considering some of the obstacles they might encounter due to the Professor’s faulty memory. As Root points out, not only will getting the Professor to the game be an issue, but there are potential pitfalls at the game itself given that the Professor thinks the year is 1975. Even though it works out okay, the incident reinforces just how much the Professor’s accident has alienated him from the outside world.

Additionally, the game kicks of the string of events that leads to the narrator being fired. The figure of the widow has hung ominously over the events of the novel. When the Professor comes down with a fever, the narrator must choose between breaking the widow’s rules by contacting her and breaking the agency’s rules by staying overnight. In the end, she takes on the responsibility of caring for the Professor but loses her job for it.

The game is significant in other ways, as well. Up until now, the Professor has only experienced baseball through numbers—even when he was younger, he never listened to or saw his beloved Tigers play, and in fact wasn’t even aware that you could listen to or watch a baseball game. The Professor experiences the world in a unique way —his one love outside of numbers is baseball, but even that only seems to be because of the nature of baseball, for which statistics plays an unusually important role. (Not many other hobbies could be experienced purely through statistics.) But now, sharing the game with the narrator’s family creates another point of connection between the Professor and Root, as it is the first game for both.

Finally, the game makes the narrator realize how much she has inadvertently denied Root by focusing so much on her own work.

The puzzle-solving and pattern-finding talents the Professor displays in the section further complicate the nature of his memory. He has already shown his affinity for numbers, but his ability to manipulate words demonstrates a feel for language that is tied to memory and mathematics; likewise, his ability to know where the evening star will appear in the night sky is an instinctual, incremental form of memory that still moves from one evening to the next.
