Happy Cubs opening day! 2018 has not been the reading year I had planned on so far. Real life and the stress that goes with it have gotten in the way of being able to focus on reading. Hopefully that changes. In the meantime in honor of the Cubs first home game this year, I am reposting my favorite baseball book from last year, a lovely novella that I am fortunate did not fly under my radar.

Life by the Numbers

Numbers are everywhere - Real, Natural, Imaginary, Perfect, Amicable, Abundant, Deficient, Triangular, Prime (including both Mersenne and Pernicious as well as Twins) to name a few. And they're all here in The Housekeeper and the Professor, which Ms. Ogawa wrote in 2007. The Professor is of mathematics and has amnesia; the housekeeper is devoted and has a son. This melange constitutes the cast of a charming story of mathematics and love, subjects with a connection that is less
On originally reading a description of this novel I wondered if it was really for me. Did I want to read about a Professor with a memory span of 80 minutes and the Housekeeper who assists him? I'm so glad I decided to read it and I'm happy to have my own copy. This story of memory, math, building a pseudo-family where no relationship has existed before is full of love and compassion. The emotions are mostly expressed in mathematical theorems, cooking and random touch, but it is palpable througho ...more

“The Professor loved prime numbers more than anything in the world.”

"To me, they were just numbers.” says the new housekeeper.

“”What’s your shoe size?” This was the Professor’s first question, once I had announced myself as the new housekeeper. No bow, no greeting.”

The professor had been involved in a motor vehicle accident, and now his memory is only of the last eighty minutes. Every morning the housekeeper introduces herself. Every morning

Amicable numbers – pair of keyrings Nerd Romance (

Not that kind of love story, but a sad, sweet story about an unlikely friendship between a brilliant mathematician, his housekeeper and her son. There is love just no romance.

A wonderful, heart-warming story about unlikely friendships....and math...and baseball! I decided to grab this one for my Japanese reading challenge for 2018 and it was the perfect story to begin reading. It's heavy into math, which I must say, I'm a bit rusty on. I was at one time fascinated by numbers, going to the highest level of math courses in college, and working for my college math professor. But then...I just lost interest in numbers (as along came computers! Nerd!)

The Housekeeper and the Professor is a charming and enjoyable novella about eponymous Professor of mathematics who due to accident years earlier suffers from peculiar form of amnesia and while he remembers everything from the past his current memory lasts only eighty minutes, and as a reminder of this fact he has fitting note pinned to his suit. In fact Professor has plenty notes on him that rustle when he walks. It is a story about his housekeeper, young single mother and her son named by Pro ...more

With only 192 pages, it is a breeze. A delightful pause. A little gem of fantasmagoric proportions. An ode to maths. And a Dennis The Menace- moment in nostalgia.

The Dennis The Menace-moment.(view spoiler)
An enjoyable Japanese novel that scatters numbers, and facts about the brain, though it's primarily about friendship. It feels light, but prompts profound questions.

The eponymous housekeeper is a young single mother (herself the only child of a single mother) with a ten-year-old son. She becomes daily housekeeper to a former maths professor whose head injury in 1975 means he only remembers the most recent 80 minutes, plus things before 1975, nearly 20 years before the story is set (~1992)

Everyone and their mother read this last year for Women in Translation month (August 2016), and I remember finding my own copy at the annual literacy book sale. I set it aside for WIT month this year and was happy to pull it back out.

The housekeeper is a single parent, trying to make enough to live on, and the professor is a mathematician with a failing memory. The story is about connection and care but also MATH and anyone who knows me knows I'm a sucker for math. The professor can't remember p

This is a beautifully-written, elegant little book about an old man, a maths professor, his housekeeper and her young son. The professor's memory post-1975 is only 80 minutes long, so everything is fresh and new to him all the time, including the news his memory is only 80 minutes long. The housekeeper has her own problems but finds fulfillment in the relationship, ever renewed, between her son and the professor and her growing love for mathematics. It is a mark of the author's writing that the ...more
A highly polished, smooth, shining surface of a novel that was exquisitely crafted from start to finish. The voice was so understated and matter-of-fact that I would have had little trouble believing that this was an actual account of a real housekeeper remembering her experiences. There were very few authorial flourishes and all of them were appropriately put into the mouth of the strange, afflicted Professor, a math genius whose short-term memory only lasts 80 minutes.

3.5 Star

The Housekeeper + The Professor by Yoko Ogawa is a heart-warming story about a housekeeper, a professor and the housekeeper’s ten year old son but also and most importantly a story about what it means to live in the present, and about friendships, family and respect and a little Math thrown in for good measure.

"He is a brilliant maths professor who lives with only eighty minutes of short-term memory. She is a sensitive and astute young housekeeper who is entrusted to take care of him"

This is a quietly wonderful book. When I was reading it I really liked it. Now that some time has passed I still think of it, and any book that I still remember months after reading is a book that deserves 5 stars. Although there is some advanced math in the story the author doesn't expect the reader to understand all of it. The numbers and math are used more to show the magic of numbers and how math brings an unlikely group of people together to form meaningful relationships.

کتاب موضوع متفاوتی داره. فصل های اول خیلی کشش داره ولی از جایی به بعد روند داستان دیگه یکسان میشه.

This is a lovely story where kindness turns unrelated people into a family. The Housekeeper is hired to cook and keep house for a Professor of mathematics who had a traumatic brain injury after a car accident. Although the Professor can remember events that happened before the TBI, this injury resulted in his short-term memory lasting only eighty minutes. It seems like they are meeting for the first time every day.

The Housekeeper and her ten year old son interact quite well with the professor s

I’m not sure on which page I fell in love with the wrinkled, snowy-haired Professor in his rumpled suit with the scrap-paper reminders pinned all over it (the most important one being the note that reads “My memory lasts only eighty minutes”). I just know that about 50 pages from the end of the story, I found myself digging in my heels, wanting to linger over every last word. The Housekeeper and the Professor is a gently written, beautiful musing on the nature of friendship and familial love. An ...more

This was a delightful story about a single mother, who was also a professional housekeeper and her 10 year old son Root, befriending her new employer, a retired math professor, who due to a tragic accident is left with the ability to only retain information for eighty minutes, before it vanishes from his memory. This was such a uplifting book about the strong bond of friendship and how beautifully the housekeeper, the professor and Root all truly became better versions of themselves from this ne ...more
This book is truly original, not your normal run of the mill. I highly recommend it. What is it about? It is about friendship and the beauty of numbers and baseball. And more..... Where should I start? I will start with the numbers. This is sort of the easiest to expalin. This book made me see and feel the beauty of math, of the laws that govern numbers.

It gets depressing when all you read is about tragedy, conflict, injustice, loss or regret. Then a feel good book comes along like a breath of fresh air. This is a charming, bittersweet story, and unexpectedly so. I was initially drawn in by the plot, the Professor, who after a traffic accident is unable to retain any new memories longer than 80 minutes. While this quirky device supports the entire story, it is not the star. There were numerous explanations of mathematical puzzles and facts and ...more
This slim book hit all the right notes for me. I love stories about "found family", in this case a brilliant mathematician with an 80-minute memory from a decades-ago accident, a housekeeper hired to clean and cook for him and her 10-year-old son. I love stories about baseball and it was so fun getting a glimpse of what baseball in Japan is like, especially right at the start of our baseball season and right after we had played Japan in the World Baseball Classic. And baseball helped bring these ...more

After our first full day visiting Japan in 2011, I saw a baseball game on TV (had to be a replay because it was December): the Yakult Swallows versus the Hanshin Tigers. I recognized Matt Murton of the Tigers who'd briefly played for the Chicago Cubs and the name of the 40-year-old Miyamoto. Two evenings later, in Nara, we got caught up in a small parade on the main street and as it ended, a young man straddling a bicycle caught up with us to ask if we were Americans and, next, if we knew Ame

How can I possibly put this book into my own words? I can’t begin to imagine I could capture or convey to any of you, how this book made me feel. It took me two days to read and I wish I could have taken more time to read it – but I simply couldn’t put it down. The pages seemed to turn themselves and I didn’t really feel like I was reading at all.

Imagine going to work and having to introduce yourself afresh to your employer every day. Will it drive you crazy if the first question you had to answer at the door each day is “What’s your shoe size?” ?

A housekeeper, a single mother with a 10-year-old son, finds herself at the cottage of a 64-year-old Math professor who has had nine housekeepers before her. She expects a difficult client, but what she least expects is an affection that develops into a strong friendship.

The poetry of mathematics and the beauty of baseball are two phrases I would never have uttered before reading this book. A math equation makes my eyes glaze over, and I think baseball is the second most boring sport to watch. (Golf is #1). But like all great literature, this novel caused something inside me to shift and change.
The four characters in this tale are nameless, known only by their titles of Professor, Housekeeper, Sister-in-law, and Root, the housekeeper's 10 year old son, so nickna

This was such a charming and heart-warming read: there was so much beauty in the writing, on the surface simple yet at the same time filled with hidden meanings and complexities, just like the intricate lace the housekeeper imagines, with awe, that the mathematician professor is able to glimpse.
