Coffee, Love, and Matrix Algebra is a delightful work of fiction that chronicles the events of roughly a year in the life of the mathematics department at a university in Rhode Island. Can there be entertainment value in a book whose principal characters are math professors? Believe it or not, this is a page turner: The reader becomes emotionally invested in the ten to fifteen central characters and humor abounds throughout.

Many of the familiar features of academia are present. Faculty spar with administrators and faculty spar with faculty. In this particular department, there are essentially two groups: an energetic society of junior faculty engaged in exciting research, mostly in applied mathematics and/or statistics, and a smaller collection of senior faculty who no longer are â€” or never were â€” doing research. Members of the latter group for the most part stand in the way of the various initiatives that the younger faculty propose and strive to realize. Which group will exert more influence?

The main character is the very self-absorbed Jeffrey Albacete, whose fame in mathematics circles is due entirely to his very popular textbook *Matrix Algebra*, now in its 9th edition. Jeffrey is content, knowing that he is regarded internationally as an expert in matrix algebra. In Jeffreyâ€™s opinion, the International Linear Algebra Society puts too much emphasis on linear algebra. The breakaway International Matrix Algebra Society, of which Jeffrey is a founding member and past president, puts the emphasis in the right place â€” on matrix algebra â€” and holds his textbook*Matrix Algebra* in high esteem. This is academic math humor done right.

Jeffrey enjoys sitting in his office and looking over all of the editions of his influential textbook. He also enjoys drinking coffee. Part of his routine is to walk to the campus gym, spend a few very leisurely minutes on the exercise bike, and then head over to the Daily Grind, a campus coffee shop. While he waits in line to order coffee, he counts the number of customers ahead of him in the queue and estimates the number of bricks on the wall. He muses about how humans start with counting and then progress to advanced topics like matrix algebra, of which he is an acknowledged expert. (Readers who share Jeffreyâ€™s counting compulsion might want to count how many blueberry muffins he consumes over the course of the story.)

Fortunately, most of the abundant humor in the book derives neither from mathematical compulsions nor from the perceived strangeness of mathematicians. Most of the characters would be at home in any intellectual line of work, and much of the bookâ€™s humor in founded in the charactersâ€™ humanity, especially in their relationships with each other. Numerous ironic comments and observations, ranging from explicit to subtle, focus on charactersâ€™ foibles and interactions; the best of these remarks are worthy of Austen or Trollope. So one need not be a math professor to enjoy the book, although it is undoubtedly helpful. Granted, plenty of the mirth derives from the absurdities of academia, and the story delights those of us on â€œthe insideâ€ because it paints such an accurate picture of our work lives. Thankfully, however, perhaps even this academic humor can find an audience beyond the ivory tower: When situations arise that might be opaque to â€œoutsiders,â€ the author routinely devotes a paragraph to spelling things out.

The characters who receive the most favorable treatment in the book â€” including those outside the university â€” are young, bright, driven, and for the most part technologically proficient. Their home is scientific computation, broadly defined, as they work to both advance and disseminate knowledge. One character who does not dwell in this realm is Alex the dog, who like Snoopy doesnâ€™t talk but has powers beyond those of the typical canine. Another non-human character is perhaps the authorâ€™s favorite: Wolfram Researchâ€™s Computable Document Format. It is lauded throughout, even to the point that on more than one occasion someone conjectures that MathWorks must be sweating bullets.

Most of the main characters have good intentions as they strive to excel at their jobs and positively influence those around them. The characters frequently offer each other (and us) a healthy dose of simple wisdom, such as to view the vagaries of life not as problems but as opportunities. Over the course of the story, the optimistic and energetic characters do exert an influence on the pessimistic and moribund, but exactly how I will leave to the reader to discover. This is an enjoyable read and highly recommended.
