Turns out that pi's not as humble as one could imagine. That many people actually did die as a result of many of the errors is tragic and definitely takes most of fun from the comedy. The unfortunate book name aside, it's a magnificent read into how maths go bump in everywhere.

Knew I was going to love this book when I opened it and immediately saw the page numbers going the wrong way.
It is a lot of fun the whole way through. Parker takes us through some of his favourite, or some of the more noteworthy, cases of maths going wrong across a variety of applications. We're talking engineering and computing, from bridges to spacecraft to calendars to ancient sumerian tablets. His enthusiam shines brightly through, and it's hard to not be infected by it. His writing is

I love maths. I enjoy finding out about mathematical and statistical errors. I was thinking some of my maths teacher friends might enjoy it and find it useful for illustrations in class. Thats where the plot breaks down a little.

I enjoyed the book but was a little disappointed that so much was taken from fields of computing and engineering, where the issue wasn't strictly a mathematical failure, but a failure, for example, to understand the limits of binary, or load-bearing, or resonant

I really enjoyed this book!

I'm one of those people who got labelled "bad at math" at a young age because I struggled with arithmetic (and still do). That resulted in my getting handed a lot of books of "math is fun!" type puzzles when I was a kid, which were definitely much more fun than math class. I learned to differentiate "math" from "arithmetic" and stubbornly took math classes up through calculus, which was fascinating, but which I've sadly never had any occasion to put to use. To make

Collection of anecdotes, some of which I knew, but the bulk of them I did not. Explanations for "uninitiated" are neither long-winded nor tedious, stories are quite interesting, and I found that the book flows really well. Can recommend

Matt Parker had me thoroughly enjoying this collection of situations where maths and numbers go wrong in everyday life. I think the book's title is a little weak - 'Humble Pi' doesn't really convey what it's about, but that subtitle 'a comedy of maths errors' is far more informative.

With his delightful conversational style, honed in his stand-up maths shows, it feels as if Parker is a friend down the pub, relating the story of some technical disaster driven by maths and computing, or regaling us

A Christmas present book from a relative in recognition of my past technical career.
Each chapter a nugget of information about some ‘maths’ error that has caused us problems in everyday life. I put ‘maths’ in inverted commas as many of the issues may be a poor engineering implementation of some analysis. As each chapter is independent of others it’s easy to dip in and out of the book when one fancies light relief from the more serious business of reading fiction!

Not normally a book I’d review on

Not so much a comedy since most errors ended up as tragedy. And yet, it is an important book to be written - what with mushrooming engineering colleges churning out supposed engineers every year!


The author doesn't dumb it down and hence some of the places are tough to comprehend. At the same time, the errors which were non-tragic and even funny (like Gandhi going all nuclear thanks to math error) were explained with so much passion that make your trivia quotient.


Some of the concepts were high

Humble Pi is a brilliant piece of writing which will make you laugh at least once on every page. Matt is a mathematician and you can easily tell that even if you don't have much background about him, by his style of writing.

The book's 11th Chapter in particular was so breathtakingly gripping, that I finished it in one go. Even the other parts of the book read like an epic collection of short stories, each of which, combined with excellent writing skills, provide for am exhilerating experience.

What if one-third of all spreadsheets included at least one formulaic error? What if the reason the shuttle crashed was not narrowly due to brittle o-rings but because the estimates of reliability themselves were fundamentally flawed? Parker takes the reader on a fun tour of our societal reliance on robust arithmetic ("maths" in his quaintly Queen's own rendition) and the degree to which our 'maths' are riddled with error. Although his search for humor tends toward trying too hard the work ...more

Summary: not very interesting, and it's not about maths errors.

This book is a collection of anecdotes that you can read anywhere: most of them I had read before, and you can find them on the internet, too. They're bundled by theme here, which is convenient, but the writer tries too hard to make them appear connected, and more often than not that results in uninspired paragraphs. Here's an example from a random page:

"Humble Pi" is a good title. "A Comedy of Maths Errors" is not a good subtitle.

The book is occasionally funny but too many people die during the stories for it to be a light read. The author mention problems in getting real world examples without turning to disasters, and it is noticeable. A good book but not what I was expecting.

This time it's a fuor-and-a-half stars, not that it will hurt Matt in any way. Humble Pi (love both the title and the cover design) talks about mathematical errors that happen or happened in the past. From MS Excel being too smart for its own good to programmers taking intended or unintended shortcuts that cause everything from annoyance to death, this book covers most of it.

Unlike Things to Make and Do in the Fourth Dimension, Matt's other book, this one will not make your head hurt and brain

Did I just listen to an over 9 hour audiobook that was solely about math?
--Yes......

Did I completely enjoy myself?
--ABSOLUTELY!

From this book, I learned that the author has strong feelings about using excel as a database, calendars are complicated, and puns are the purest form of humor.

If you are not the best at math (like myself) I highly suggest listening to this book because Matt makes it so easy and entertaining.

I was a bit worried a maths book would be tricky to follow as an audiobook, but I also like how Matt Parker explains things, so I was delighted he reads the audio version himself - it works very well! Occasionally the numbers were more of an inscrutable chant than actual information I was taking in, but it was still a good romp through various maths-related screw-ups of varying seriousness. Good fun.

This is probably very good, if you get numbers.
I never have. Got a D for Maths at school, retook it a year later at college and got an E. I kid you not. Definately a word girl.
But I do nod my head to numbers and their importance. Saw this book and thought I'd try and reestablish a relationship. Alas its no good - we're just not meant to be.
Martijn Reintjes
Don't get me wrong, I love math, and I love stories.
But it takes a real skill to tell stories about math and fill a whole book with it and keep it compelling.
This book wasn't.

Sure the stories where fun
And the math problems interesting

But math can be dry, and Matt wasn't able to keep the story moist.

It is a fun read. I would say it is more geared towards software errors than math errors, so if you like computer science, you will appreciate it. Only downside: if you follow the author on his YouTube channel, you will have heard already about a sizable fraction of all the facts presented.

I actually listened to the audiobook version, and the fact that the author himself narrated the book adds a lot to the experience, in this case.

This book is a collection of real-life stories (maybe with some fictional details to make them sound more interesting) about math, and casualties, which may be caused by math errors.

Broken bridges, overdosed patients, missed missiles, crashed satellites and day-to-day misconceptions are beautifully explained by author, with a good amount of jokes.

Recommend to read.

It is an easy read which is quite hilarious. Despite the author is sometimes being too shallow on particular topics, I learned some new interesting facts and I can now definitely talk about bridges of all sorts.

Lots of interesting anecdotes. Sometimes the math and science explanations went over my head. Quite funny.

Entertaining:
A maths book that is fun to read. As anyone who knows me will be aware I love maths, but you don't need much maths to read this book. Everything is simply explained. Matt Parker shows why maths is important in the real world, by giving humorous examples of when it all went wrong.

An interesting and sobering view...

This is a funny book about math fails (or “maths” as the author says). This is a humorous and fun book exploring math (and related) errors. I would recommend it for anyone. Though, there is the tiniest bit of language and it might help to know some pop culture (and mainly historic) references. Overall, I enjoyed this book but maybe got a tiny bit bored here and there.

These are my stray thoughts:

Matt Parker is pretty good at turning maths into an accessible subject. I already read his other book (Things to Make and Do in the Fourth Dimension) recently, and it turned out he narrated his own audiobook, so I tried that version this time.

In some ways, I feel like I missed out on the diagrams from the book itself - maths can be very visual sometimes - but I gained a lot by Parker's lively narration. In fact, when he gets to parts of the book that are difficult to narrate (such as long
