Humble Pi takes us on a tour of the times when math, engineering, and programming have gone wrong, leading to disastrous or sometimes just funny results. The book covers a range of mistakes, including bridge failures, space exploration disasters, game show cheats, financial algorithms gone rogue, and so much more.

I pretty much loved this book from start to finish. I found it thoroughly fascinating and often hilarious. Parker has a great way with explaining technical subjects, distilling it down ...more

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.

There is an Australian word that is used to describe people that is affectionate, but when you learn its etymology, you wonder how it possibly ever could have come to common use. It is to be called a dag, or more likely, a bit of a dag. It isn’t exactly a compliment, but it almost always implies a fondness for the person being spoken about.

It is to be called a dag, or more likely, a bit of a dag. It isn’t exactly a compliment, but it almost always implies a fondness for the person being spoken about. You know, if in context you call someone ‘a bit of a dag’ you would not be likely to get into a fight – whereas, if you called them a shit-head or a total-turd or a prick, you really might. The thing is that a dag is a piece of shit that hangs from the wool around a sheep’s bum. Like I said, you couldn’t say being called a dag is a compliment, but it isn't really an insult either. I say all of this because this guy was born in Western Australia and, well, he's a bit of a dag. Oh, and by the way, I’m typing this in Microsoft Word using the Australian English dictionary and I have to say it amuses me very much indeed that ‘dag’ has a red squiggly line under it informing me that I’ve made a spelling mistake. Australian English, indeed.

There is a point in this book where the author started a campaign to have the soccer ball depicted on signs in England changed to ensure that it was not made up only of hexagons, but also included pentagons. He explained that if all of the segments in the ball were hexagons you couldn’t make it into a ball. Now, look, I get it – he’s a maths guy, and so getting it right is important to him – but sometimes you need to move on. It’s a bit like a meme I saw early in the pandemic showing right angle triangles with all sides being 1.5 metres, and then Hawking and deGrasse Tyson holding back Pythagoras who was ready for a fight. My all-time favourite of these things is the fact that it is impossible to see a cube in real life in the way we have all been taught to draw one, with a square on the top of the cube and two sides also being squares. You can get upset about these things, but 2-d representations of 3-d phenomena are, well, you know, 2-d.

Quite a lot of this book discusses mistakes a bit like that. But other mistakes are much more consequential – you know, the sort of mistakes that make planes fall out of the sky. What is really interesting with these things is that those mistakes can be quite difficult to make. Not that you have to really try to make them, or put in lots of effort, the mistakes come easily enough, but a whole lot of things need to go very wrong for some mistakes to happen – that is the lovely thing about this book, it is quite forgiving of those who make mistakes – given that that is all of us, just about all of the time. His point isn’t to point and laugh, but rather to explain that any system based on the assumption that no one would be damn stupid enough to make that particular mistake has been designed to fail. In many of the stories here you might find yourself feeling rather smug – but as they say in the classics, ‘pride comes before a fall’ and ‘there but for the grace of God go I…’ It is really worth while keeping those little quotes in mind here.

The metaphor he uses at the end of this is hot Swiss cheese, but I preferred the straight Swiss cheese one used earlier – that is, there are always holes, you need to make sure that the holes in your defences don't all line up. We probably can’t make sure of that, ultimately, but setting that as your life’s goal is a worthwhile thing to do. If you are smart, the challenge is to create something that will be as close to foolproof as you can, rather than blaming people afterwards for not using it properly.

Right at the end of this there is a quote from him that has ended up being used in mathematics classrooms by teachers – and I love it to bits. It is, “Mathematicians aren’t people who find maths easy; they’re people who enjoy how hard it is”. Isn’t that the best thing you’ve read today? One of the things that always annoys me is that so many people seem to understand some things about sport that they never seem to connect with intellectual effort. One is that no matter how good you are at a sport, you still need to practice. And that if you want to be really good, you have to practice a lot. If I was to wear a ‘I’m too intelligent to play football’ t-shirt, I would, rightly enough, I guess, be considered grossly insulting. But I have seen a ‘I’m too pretty for maths’ t-shirt. The effort required to be good at any skill is almost always actually the point – but too many people seem to think that a skill needs to be 100% innate or it isn’t a real skill.

The other connection to sport is that you can be the best at your sport that has ever been, and you will still fail over and over again. Don Bradman’s last score in a test match was a duck. Michael Jordan once said, ‘I’ve missed more than 9,000 shots in my career’. Yeah, he probably ought to have just given up, he clearly didn’t have any natural talent for that shit. The thing is that people give up on mathematics for far less. I’ve actually a negative interest in sport, zero being far too large a number to fully encompass my boredom – but I find it remarkable that people are so much more likely to give up on things that are really worthwhile, but would ‘never say die’ for shit that doesn't matter at all.

Anyway, I distract myself – while it is worth reading this book if only to see the near endless number of ways we can stuff things up, there are other joys involved here. Some of the stories read like jokes – in the sense that you know there is going to be a punchline coming soon, and so you try to guess it before it comes. Sometimes the punchline will come and then he will explain that the punchline was actually only one of the things that needed to go wrong for the whole thing to come crashing down. He also explains that sometimes stuff ups are necessary, rather than just tragic accidents. Progress in science and engineering often involves someone needing to go beyond the cutting edge, on to the bleeding edge. But to boldly go where no one has gone before is risky business. Not all mistakes are stuff-ups, sometimes they are a necessary consequence of being first. ...more

Matt Parker’s narration of the audiobook made this one even more fun to listen to. I found plenty of humor in his very drawn out rendition of “0.00000000000000000000000000167.” There are bountiful opportunities for him to narrate very large and tiny numbers without using scientific notation, and I personally found this fun. For all those who (realistically) would be annoyed rather than gently amused, I would probably pick up the hard copy instead.

Each chapter houses its own topic that is largely unrelated from one to the next, and various pieces of trivia are launched with Parker’s witty commentary for some interesting discussion. For example, computers using a signed 32-bit counting system to track time will no longer be able to 2,147,483,647 seconds later from the start of 1970 (at which point in 2038, who knows whether the world will have fully chucked out computers for ~~phones~~ tinier gadgets). Or based on the Affordable Care Act’s 3x maximum cap on older individuals’ insurance premiums, the Trump Administration tried to argue that older customers could be charged 3.49x as much. Yunno, because 3.49 ‘rounds down’ to 3. That failed, but yeah, nice try.

Doing math can often be in turns maddening or tiresome. For the average folk, we never fully manage to put a finger on the utility of an integral or the need to prove that an isosceles triangle has two same sides (can’t I just believe it, 8th grade Geometry teacher!?!!?). But for all the chuckles we can derive from laughing at silly mistakes, Matt Parker shows the rampant fallibility in our application of maths, hounding the gambler to the government official to the bridge engineer and certainly to us. Careful counting matters more than ever right now, and we should be wary of math errors—at the very least, Humble Pi offers a useful distraction to seeing numbers other than that everlasting tally for the election. ...more

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.

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.

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 here. I don’t go for popular science of this type, anecdotal though informed, commentary on technical mistakes. I’ve found that in the modern era many science bloggers online can provide up to date light or serious reviews of technical problems in a digestible and easy to understand form. Books on the same topic seem to me too frozen when a lively discussion online, something interactive, is often a better way to understand the problem. Just my view though.

This book is better than most popular ‘wow, isn’t that silly scientists did this’ books. About half of the chapters I did find genuinely interesting (eg how clocks in computer operating systems can be designed to count down from some very high number on the assumption that time zero will be well beyond the expected operating life of the system - guess what?!). Some, such as how numbers placed in spreadsheets in a text format can lead to errors interpreting spreadsheet outputs, had me yawning! But if you’re prepared to ditch out of chapters quickly that you don’t enjoy and move onto the next it’s generally an interesting read.

I think the author has great talent for popularising some difficult science and maths concepts (he does well with probability) and he’s easy to read but it’d be better to see it used for one grand concept in a book rather than this mish mash of the interesting and mundane. I know it’ll be a matter of a reader’s interests but about half of the book covered topics I regarded as dull, so you’ll need to work to find the ones that interest you.

If you get it as a present then worth a read but I wouldn’t go out of my way to recommend it for a purchase, if you want an interesting popular science read. ...more

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 with a numerical cock-up. These range from the spectacular - wobbling and collapsing bridges, for example - to the small but beautifully formed, such as Excel's rounding errors.

Sometimes it's Parker's little asides that are particularly attractive. I loved his rant on why phone numbers aren't numbers at all (would it be meaningful for someone to ask you what half your phone number is?). We discover the trials and tribulations of getting calendars right, explore some of the oddities of probability, enjoy a bit of impossible geometry and see how getting units right (or wrong) can make all the difference. Of course there are the big stories, from NASA disasters to the risks of trying to crash onboard systems on planes mid-flight. But it's often those little details like the phone numbers that tickled me. I loved, for example, Parker's attempts to get the footballs on UK signs geometrically correct - totally misunderstood by the bureaucracy - or when Parker points out the problems of graphics featuring multiple cogs interlocked with each other in a way that will lock them solid - not to mention his combinatorial struggles with the McDonald's McChoice menu.

The only thing I did find - and this is the only reason the book doesn't get five stars - is that the final couple of chapters seemed a little samey. Rather than save the best to last, Parker resorts to revisiting rather familiar feeling computer problems, which are interesting (but perhaps more to me, with a background in computing, than many readers), but by now not quite as original and fresh feeling.

However, this is an excellent read, managing to be light and meaty at the same time, and highly recommended for anyone interested in maths, business or computing. ...more

A former maths teacher, he has made a living for himself popularising maths tours and videos in real life and online. He has previously written one book on the topic of mathematics, Things to Make and Do in the Fourth Dimension, as well as co-writing Hacking the Kinect.

The book of his I will be reviewing is non-fiction, Humble Pi, A Comedy of Maths Errors, published in 2019. The book focuses on many mistakes in real life consequence of bad mathematics in an interesting and often comedic way. It explores the relationship between the human brain and its ability to process and handle the complex processes of modern day mathematics. While cheeky and childish at times, the book also dwells into a more serious point of views in which the consequences of poorly done calculations can result in drastic cases of enormous economic loss and fatal accidents. Many themes are brought up throughout the book, many of which expand beyond the literal confines of mathematics.

I thoroughly enjoyed this book. Some of its most likeable characteristics included humour, jest and larrikin, which provided a warm contrast to some of the darker themes brought up in the read. It can become slightly complicated in some areas, and some advanced mathematical knowledge may be required for some readers. I sometimes struggled to get my head around some of the topics provided in the book. However, I don’t think this will stop most people from turning away from this book. Most of the time it is an easy to read, lightweight book that takes the reader on an enjoyable ride around the world of mathematics.

One of the very many potent themes in this book is the claim that maths is ignored or disregarded in everyday life and there is a significant disrespect from those who believe maths is unimportant. Parker exclaims “My main point was that there is a general feeling in society that maths is not that important; that it’s okay not to be good at it. But so much of our economy and technology requires people who are good at maths.” Parker presents an interesting idea to explore about the relationship between society and maths. The idea that when maths is quickly pushed aside as inessential or inconsequential, it creates a message in society that it doesn’t provide any meaningful contribution in everyday life. Even as young as primary school, students wonder how maths will be of use of them in the future. And for years 11 & 12 at my school, english is compulsory while mathematics is not. Parker amplifies this idea as well by incorporating real life consequences in his book. He reports “Both mistakes together resulted in the deaths of 114 people...The vast majority of the time, people cross bridges and walk across walkways blissfully unaware of how much engineering has gone into making it possible. We only really notice when it goes wrong.” This quote is on a more serious level to the previous one, as it includes a real life consequence of maths errors. The mathematics error responsible for the deaths of 114 in the Kansas Hyatt Walkway Collapse in 1981 was the result of a simple one extra nut added to each of the walkway beams. Parker includes this example to show the reader real issues with bad mathematics, and how a more concrete understanding of it could greatly improve safety in the areas of industrial physics and maths.

I would recommend this book to anyone that has even a mild passion for mathematics. It does a tremendous job at exploring a wide range of mathematical quandaries, and suggesting ways they could have been improved. It takes the reader on a journey through time and space to events and experiences I thought not possible to be communicated through the written word. It takes you all around the world, to famous locations and events to exploit mathematical errors, including the Sydney Harbour Bridge and some of NASA’s failed projects. Overall, I think it is a very good book, 9/10.

This book is about math. It's wonderfully nerdy, endlessly fascinating, and - believe it or not - incredibly funny.

I laughed and learned a lot throughout the course of these pages, but most importantly the book left me with an important message: math is powerful stuff, and mistakes are bound to happen when dealing with powerful stuff. However, it's important to learn, rather than hide, from these mistakes.

There are so many fun concepts I loved from this read, and will definitely need to pick up This book is about math. It's wonderfully nerdy, endlessly fascinating, and - believe it or not - incredibly funny.

I laughed and learned a lot throughout the course of these pages, but most importantly the book left me with an important message: math is powerful stuff, and mistakes are bound to happen when dealing with powerful stuff. However, it's important to learn, rather than hide, from these mistakes.

There are so many fun concepts I loved from this read, and will definitely need to pick up a copy to reread and reference in the future.

Here are a few that I especially loved:

- non-transitive "Grime" dice: a multicoloured set of 5 dice that you can use to play a game of Highest Number Wins... and effectively cheat your way to victory by knowing which of the seemingly comparable die is actually probabalistically weighted to win against another. I WANT A SET OF THESE.

- the Y2K38 bug: computers have an internal system that keeps track of how many seconds have elapsed since 1970, when the first precursors to the modern internet started to come online. This system is built on a 32-bit binary number, meaning it can hold a maximum of 2,147,483,647 seconds, or 68 years. Meaning that at 3:14am on Tuesday, January 19, 2038, a whole lot of machines are going to be very confused. Many devices are being updated to 64-bits (which would be able to hold the equivalent of 292.3 billion years), but those that aren't won't fair very well!

- as Awesome as Excel is, it has some shortcomings. It's not ideal as a database storage due to its lack of transparency regarding cell reference formulas. It also has a tendency ncy to misidentify the type of data a person is inputting (eg translating a phone number into scientific notation, because it thinks its just a really large number).

- The Swiss Cheese Model of accident causation: any system can be viewed as a collection of multiple layers, each with defenses and mechanisms to prevent mistakes. However, each layer has holes. A disaster occurs when an incident manages to wheel its way through each

- The Hot Cheese Model of accident causation: "imagine the slices of cheese are horizontal and mistakes are raining down from the top. Only mistakes which fall down through holes in every layer make it to the bottom to become accidents. The new element is that the cheese slices themselves are hot and parts of them are liable to drop down, causing new problems... Adding a new layer does not automatically reduce how many accidents are happening."

- CHI+MED (Computer-Human Interaction for Medical Devices) project: a collection of UK universities and hospitals that banded together. They believed that instead of individuals to blame for maths/technology mistakes in medicine, the whole system should be geared to avoid errors ...more

A very frequently seen meme on social media asks which book really made you cry with the answer being,'My Maths textbook', an answer that strikes a cord with many many people!
Complaining about how abstract mathematical concepts seem in school and college to wondering when we will ever find practical use for differential equations and calculus to growing to appreciate how much of what we have learnt is silently making things work all around us is a journey many of us make.

This witty, insightful ...more

Quotes from Humble Pi: A Come...

“one thing is causing another. There is always the chance that something else is influencing the data, causing the link. Between 1993 and 2008 the police in Germany were searching for the mysterious ‘phantom of Heilbronn’, a woman who had been linked to forty crimes, including six murders; her DNA had been found at all the crime scenes. Tens of thousands of police hours were spent looking for Germany’s ‘most dangerous woman’ and there was a €300,000 bounty on her head. It turns out she was a woman who worked in the factory that made the cotton swabs used to collect DNA evidence. And, of course,” — 7 likes

“In February 2007, six F-22s were flying from Hawaii to Japan when all their systems crashed at once. All navigation systems went offline, the fuel systems went, and even some of the communication systems were out. This was not triggered by an enemy attack or clever sabotage. The aircraft had merely flown over the International Date Line.” — 2 likes
