    Bringing humanity to mathematics
  

*by M***T on Reviewed in the United States on January 14, 2022*

A superb teacher of mathematics tells the story of his lifelong epistolary friendship with his high school Calculus teacher.  A pleasure to read, it fills a much-needed void by bringing humanity to mathematics.  If you like this, I would also recommend “Apologies of a Mathematician” by GH Hardy.

### ⭐⭐⭐⭐⭐ 







  
  
    The elegance of math, teaching, and friendship
  

*by B***B on Reviewed in the United States on March 5, 2012*

I'm familiar with Steven Strogatz from being an avid Radiolab listener, so I anxiously awaited The Calculus of Friendship. It's a beautiful, poignant story of the intense, special, and evolving relationship between student & teacher. It is also an amazing writing accomplishment that successfully combines math and memoir. While I can't say that I completely understand all the math, the mathematics only adds to this story rather than detracting from it. It shows the true elegance & beauty of calculus, along with the elegance & beauty of working together as student and teacher to solve the calculus. Mr. Joffray is truly an extraordinary teacher, one that allows his students to teach him. I honestly wish that I could learn math from both of these men, and they are portrayed so well through their letters that I would also like to share an interesting dinner & discussion with them. Maybe they could (attempt to) further explain "differentiating under the integral sign" to me! I'm going to insist that my son read this book as he has already had some exemplary math (and chemistry!) teachers that have greatly influenced his life, and is embarking on his college career where I fervently hope he meets more of the same.

### ⭐⭐⭐⭐ 







  
  
    A very interesting book
  

*by T***R on Reviewed in the United States on November 11, 2009*

This is a very interesting book about the relationship between a high school student and teacher that extends long after the student has graduated. Because both student and teacher are math teachers, the correspondence between them frequently revolves aroung math problems that interest them, but it includes much more than that.  Not being mathematically inclined whatsoever, I skipped over all the math, and found it a touching story.  For those interested in the math too, it will be a double treat.
