The Calculus of Friendship: What a Teacher and a Student Learned about Life while Corresponding about Math by Steven Strogatz (PDF)

Description

The Calculus of Friendship is the story of an extraordinary connection between a teacher and a student, as chronicled through more than thirty years of letters between them. What makes their relationship unique is that it is based almost entirely on a shared love of calculus. For them, calculus is more than a branch of mathematics; it is a game they love playing together, a constant when all else is in flux. The teacher goes from the prime of his career to retirement, competes in whitewater kayaking at the international level, and loses a son. The student matures from high school math whiz to Ivy League professor, suffers the sudden death of a parent, and blunders into a marriage destined to fail. Yet through it all they take refuge in the haven of calculus–until a day comes when calculus is no longer enough. Like calculus itself, The Calculus of Friendship is an exploration of change. It’s about the transformation that takes place in a student’s heart, as he and his teacher reverse roles, as they age, as they are buffeted by life itself. Written by a renowned teacher and communicator of mathematics, The Calculus of Friendship is warm, intimate, and deeply moving. The most inspiring ideas of calculus, differential equations, and chaos theory are explained through metaphors, images, and anecdotes in a way that all readers will find beautiful, and even poignant. Math enthusiasts, from high school students to professionals, will delight in the offbeat problems and lucid explanations in the letters. For anyone whose life has been changed by a mentor, The Calculus of Friendship will be an unforgettable journey.

Editorial Reviews: Review “An intimate view of mentorship is revealed by US mathematician Steven Strogatz in The Calculus of Friendship, a compilation of letters exchanged with his high-school math teacher over 30 years. Through their correspondence they share problems in calculus, chaos theory and major life events, from professional and sporting successes to family bereavements and divorce. The book touchingly charts their changing roles and relationship, from student to professor, teacher to retirement.” ― Nature”The spring of his freshman year in college, Strogatz began to exchange letters with his high school calculus teacher, Don Joffray. At some point, their amiable correspondence about math problems led to a true friendship. In The Calculus of Friendship, Strogatz weaves their letters into reflections on the philosophical similarities between calculus and human relationships and portrays a friendship firmly founded on a love of dreaming up and solving calculus problems . . . . One can also feel the personality and humor of these pen pals emerging through their symbol-sprinkled sentences.” ― Science”Part biography, part autobiography and part off-the-beaten-path guide to calculus, this quick read details 30 years of correspondence between Strogatz and Joffray. Calculus, Isaac Newton’s ingenious invention for modeling change mathematically, serves as both text and subtext for the letters that pass between Strogatz and Joff. Focusing almost exclusively on questions of mathematics, these brief notes frame the unlikely friendship of a teacher and his star student. With the precision of an award-winning mathematician and the clarity of a best-selling science author, Strogatz leads us on an excursion through some of the lesser-known mathematical sights–the ones usually reserved for the ‘members only’ tour. . . . The mathematics covered in these letters is impressive for such a short volume.” ― American Scientist”There is no better English-language explicator of complex quantitative concepts than Steven Strogatz. His work is a model for how mathematics needs to be popularized.”—Michael Schrage, Harvard Business Review”This story will draw in both the novice and the veteran. Teachers of mathematics will appreciate the long-term effect their teaching can have on students. The included mathematics can be related to both high school and undergraduate calculus sequences to demonstrate some interesting, thought-provoking, and ‘big picture’ connections to these courses.” ― Mathematics Teacher”[A] beautiful book, bound to become a classic in the mathematical literature. . . . Like Hardy’s A Mathematician’s Apology, you don not have to know any mathematics whatsoever to read this book. It is a candid and all-too-human story told with brutal honesty, warts and all, sharing with the reader the elation and sincere regrets bound up in the relationship–but in the end, the victories, too. With some beautiful mathematics throughout!”—Lawrence S. Braden, Notices of the American Mathematical Society”You wouldn’t guess it from the title, but The Calculus of Friendship is a genuine tearjerker. I defy anyone to follow the correspondence between mathematician Steven Strogatz and his high school teacher Don Joffray (affectionately nicknamed ‘Joff’) without getting just a little lachrymose. If you don’t, check to see if there is a heart in your chest. If there is, ensure that it’s not just a cold slab of stone.” ― Bookslut”The story of the correspondence between these two men is at once charming and subtly powerful. Strogatz writes directly and honestly, telling the story of a slow-growing friendship that was at once somewhat stilted and yet deep and sustaining. The immediacy and intimacy of Strogatz’s writing transform the pleasures and tragedies of normal life into the elements of a compelling narrative, and because the book works so well on this human level, it also very effective in presenting some important lessons about education and about mathematics.” ― Mathrecreation blog Review “As these two men find truer, deeper friendship through an exchange of letters on math, you may be surprised to find yourself, as I was, moved by powerful emotions. I never thought I’d get choked up by an equation―but these guys are plotting out the hardest kind of change to track: the movement from Me to Us.”―Alan Alda”The Calculus of Friendship is an intriguing journey that casts mathematics in a most unusual light. Through thirty years of correspondence between student and teacher, we enter a private world where the rigors of logic are the last defense against the vagaries of life.”―Brian Greene, author of The Elegant Universe”In this delightfully inspired account of a thirty-year correspondence, two mathematicians discover even deeper things than theorems that are fundamental. A math book for the mind and for the heart.”―Larry Zimmerman, winner of the 1986 Presidential Award for Excellence in Mathematics Teaching”Steven Strogatz has written an unpretentious, charming, original, and inspiring book. In a disarmingly personal depiction, Strogatz leads us through a story of friendship between understated mentor and virtuosic student. The mathematical excursions are as much a pleasure to read as the moving narrative of the unusual friendship that the mathematics inspires.”―Janna Levin, author of A Madman Dreams of Turing Machines”It is unusual for mathematicians to write in such personal terms and with such candor. Readers with any mathematical background will find this book intriguing and fascinating.”―John Adam, coauthor of Guesstimation”The gentle but unremittingly honest account of this friendship utterly absorbed me. Also, some of the calculus is hilarious.”―John Cleese”Containing many mathematical morsels, this decades-long correspondence tells the story of a very special student-teacher relationship. These men have taught each other more than they could ever have envisioned.”―Adrian Banner, author of The Calculus Lifesaver”Mathematics speaks to the transcendental, as does this extraordinary friendship. A beautiful book!”―James Tanton, founding director of the St. Mark’s Institute of Mathematics”This is a lovely book. Strogatz succeeds in producing a sincere tribute to teachers, and he emphasizes in a direct way the human element of mathematics.”―Barry Cipra, author of Misteaks…and How to Find Them before the Teacher Does: A Calculus Supplement From the Back Cover “As these two men find truer, deeper friendship through an exchange of letters on math, you may be surprised to find yourself, as I was, moved by powerful emotions.

Reviews from Amazon users which were colected at the time this book was published on the website:

⭐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.

⭐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.

⭐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.

⭐Full disclosure: Don Joffray, about whom this book was written, was a great friend of my parents so I knew him as much more than a teacher. The great thing about this book is that the author, Steve Strogatz, paints an accurate, empathetic picture of Joff the man & Joff the teacher, and also weaves a compelling story about the enduring friendship between two math geeks (I say this with admiration). I am not a math major so some of the calculations went beyond my meager understanding, but that didn’t matter. Even the math conversations replicated in the book were glimpses into the continuum of a student/teacher realtionship. Very cool!- V. Norris

⭐This is one of the most beautiful books I’ve read in a long time. It’s the story of a teacher and student and the influence they had on each other. The student and teacher have some very powerful moments and it’s just a really great story. It’s good for people who love math (my engineer partner read and loved it) and it’s good for those who are less inclined to mathematics (me).

⭐This is an absolutely beautiful book about the relationship through letters of a high school math teacher and one of his students who becomes a world class mathematician. It’s about their lives and the mathematics that bound them together. I have read quite a few memoirs and don’t recall any that choked me up like this one did, I want to thank Dr. Strogatz for being so open. Also, the math in the book is very interesting and well explained, if I could give if more than five stars I would.

⭐A touching collection of letters between a high school math teacher and a former student which explores the role of mentoring over many decades. Although the letters contain lots of calculus, it is a truly moving story of a friendship between student and teacher that moves ever so slowly from a purely professional exchange of information into more personal territory.

⭐… and those are the types of experience that are not easy to translate from human mind to symbols, also a pathetic bounds between humans are the extreme limits of our intellectual knowledge. However the author suceeds in it’s intent to show the former bound, but not so much to the last. Indeed, the title Calculus of Friendship, gave a hint that the last was not the central point.

⭐Firstly the mathematics presented in this book is really fun stuff and will transport many mathematicians, physicists and engineers to their high school days. The communications between teacher and student through their evolving lives is wonderful, at times quite touching, and comes across as being honest rather than candy coated. I read the book cover to cover over two days, and I can’t remember the last time a book drew my attention like this. Hats off to a great book and even greater story.

⭐This is a brief but amazingly revealing account of a friendship that lasted decades and the maths problems that marked its progress more than the life events (births, deaths, marriages) which get less attention.

⭐Es un libro acerca de la amistad de un alumno y su maestro y los temas de la vida que realmente importan (matrimonio, enfermedad, mortalidad).Aunque me pareció que estos temas se trataron en forma breve. Me hubiera gustado que se hubieran tratado un poco más. Me pareció que se terminó muy rápido. Me quedé ganas de más.Está más o menos el libro.

⭐

⭐Wish we had many more teachers like Don Joffray in our schools. A Poignant tale of two brilliant minds moving through life. To add to it , the Math exchanged is insightful and mesmerizing.

⭐Ouvrage qui se lit très facilement. Le style est simple et sans prétention. La relation epistulaire entre l’élève et son professeur sur plusieurs décennies est touchante. Livre accessible à tous.
