Ll unexpectedly emerge Sometimes the addition of a little bit Mass Is All It Takes To Change The Mathematics Of is all it takes to change the mathematics of a structure behavesThis is a common theme in human progress We make things beyond what we understand and we always have done When theory lags behind application there will always be mathematical surprises lying in wait The important thing is that we learn from these inevitable mistakes and don t repeat them cIn the mid 1990s a new employee of Sun Microsystems in California kept disappearing from their database Every time his details were entered the system seemed to eat Every time his details were entered the system seemed to eat whole he would disappear without a trace No one in HR could work out why Summary not very interesting and it s not about maths errorsThis book is a collection of anecdotes that ou can read anywhere most of them I had read before and ou 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 often than not that results in uninspired paragraphs Here s an example from a random pageBut what happens when computers try to divide by zero Unless they ve been explicitly told that they can t divide by zero they naively give it a go And the results can be terrifyingYou can almost hear that in that slick documentary voice over style where everything spells doom Will the team find a way out or will they fail And in this case really I picked a random page the writer is wrong There has been no naively dividing by zero for uite some time now What happens is well defined and in many languages reuires explicit handling Ther This was one of the most highly entertaining books I ve ever read Whitty and easily digestable I would recommend this to anyone remotely interested in math or engineering 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 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 to layman terms while retaining his humor Even on events I already know about Parker s explanations provided a new and interesting takeThe book is organized so that similar themes are grouped together into chapters but each incident is only a few pages long so it never feels bogged down or boring I found it best to read with the internet handy so I could zip on and find out whenever it interested meIt s been a while since I ve been this riveted by a nonfiction book I was tearing through it chuckling to myself and stopping only to look up videos of Michael Larson on Press Your Luck and Galloping Gertie as it came down I m so glad I happened across this book It totally spoke to the inner engineer nerd in me After all the only thing fascinating than how something works is when it doesn t Knew I was going to love this book when I opened it and immediately saw the page numbers going the wrong wayIt is a lot of fun the whole way through Parker takes us through some of his favourite or some of the 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 infused with a dry wit and a good sprinkling of genuine laugh out loud humour which hopefully would make this a fun read ever for those who aren t already invested in the maths storiesMy major criticism is that despite the clear over arching theme of maths problems the book still does not feel that cohesive It has the feeling of a series of articles and just never uite manages to tie them all together or raise a greater point This ultimately doesn t matter too much though as it is still a very engaging and enjoyable read Definitely learnt a new thing or two 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 informativeWith 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 f Lots of interesting anecdotes Sometimes the math and science explanations went over my head uite funn. Putting date in decimal form leads to problems because the internal computations are actually done in binary Yet Parker has a sly wit; so although all this sounds very serious in fact the writing style is breezy and in some parts extremely funny.

A matter of a reader s interests but about half of the book covered topics I regarded as dull so ou ll need to work to find the ones that interest Kill Shakespeare Volume 1 youIfou 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 Peepland Vol. 1 you want an interesting popular science read 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 Plaintiff s insistence that the commercial appears to be a serious offer reuires the Court to explain why the commercial is funny Explaining why a joke is funny is a daunting task cI went with my favourite method of comparing big numbers to time We know a million a billion and a trillion are different sizes but we often don t appreciate the staggering increases between them A million seconds from now is just shy of eleven days and fourteen hours Not so bad I could wait that long It s within two weeks A billion seconds is over thirty oneearsA trillion seconds from now is after the ear 33700CEThose surprising numbers actually make perfect sense after a moment s thought Million billion and trillion are each a thousand times bigger than each other A million seconds is roughly a third of a month so a billion seconds is on the order of 330 a third of a thousand months And if a billion is billion seconds is on the order of 330 a third of a thousand months And if a billion is thirty one ears then of course a trillion is around 31000 Stripped (Happy Endings, years cEven after a lifetime of education dealing with small numbers there is a vestigial instinct that larger numbers are logarithmic that the gap between a trillion and a billion feels about the same as the jump between a million and a billion because both are a thousand times bigger In reality the jump to a trillion is much bigger the difference between living toour early thirties and a time when humankind may no longer exist cI believe that regardless of flight phase is official FAA speak for This could go down mid flight Their official line on airworthiness was the reuirement of repetitive maintenance tasks for electrical power deactivation That is to say anyone with a Boeing 787 had to remember to turn it off and on again A political committee is rarely a good solution to a mathematical problem cTo get everything back into alignment in the first place the ear 46BCE had a possible world record 445 days cThe building at 20 Fenchurch Street in London By all measures it s a successful building Except during the summer of 2013 it started setting things on fire The exterior of the building was designed by architect Rafael Vi oly to have a sweeping curve but this meant that all the reflective glass windows accidentally became a massive concave mirror a kind of giant lens in the sky able to focus sunlight on a tiny area It s not often sunny in London but when a sun filled day in summer 2013 lined up with the recently completed windows a death heat ray swept across London Okay it wasn t that bad But it was producing temperatures of around 90 C which was enough to scorch the doormat at a nearby barber s shop A parked car was a bit melted and someone claimed it burned their lemon that s not cockney rhyming slang it was an actual lemon A local reporter with a flair for the dramatic took the opportunity to fry some eggs by placing a pan in the hotspot cIn July 2011 a thirty nine storey shopping centre in South Korea had to be evacuated because resonance was vibrating the building People at the top of the building felt it start to shake as if someone had banged the bass and turned up the treble Which was exactly the problem After the official investigation had ruled out an earthuake they found the culprit was an exercise class on the twelfth floorOn 5 July 2011 they had decided to work out to Snap s The Power and everyone jumped around harder than they usually did Could the rhythm of The Power match a resonant freuency of the building During the investigation about twenty people were crammed back into that room to recreate the exercise class and sure enough they did have the power When the exercise class on the twelfth floor had The Power the thirty eighth floor started shaking around ten times than it normally did cWhen it was reopened the Millennium Bridge was described as probably the most complex passively damped structure in the world Not an epithet most of us would aspire to c British engineers prided themselves on their stiff upper bridges cObviously we should do whatever we can to avoid engineering mistakes but when engineers are pushing the boundaries of what is possible occasionally a new aspect of mathematical behaviour wi.

I really enjoyed this book I m one of those people who got labelled bad at math at a oung 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 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 this long story short I recommend this book to people who
think they hate 
they hate or who foundfind math difficult as Well As Technically Inclined as technically inclined who use math all the time The topics covered in this book are wide ranging and a lot of them are things Spiritual Warfare Prayers you might not even think of as being mathematical putting a padlock on a door properly for instance or people with names that get ignored by computer code Matt Parker s voice is witty without ever talking down to his audience He just really loves anything even tangentially mathematical and loves sharing it with everyone else And this book made me laugh out loud many times It s possibly all nerd humor but it was great There are three math errors in this book which I did not catch but also didn t look for very hard So this book has a math game in it Also it s numbered backwards which made it tricky to track my process through it here since Goodreads won t letou update to Page 141 when ou started on Page 316 There s also a trick to the index that I didn t figure out but the index is worth reading for itself as well I may reread this sometime and actually try to find the errors and solve the indexing But there was a waiting list for it at the library so I zoomed it back as soon as I finished it This is some of the most fun I ve had reading in uite a while So seriously even if our knee jerk reaction is to recoil in horror from the thought of reading a math book try it anyway 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 littleI 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 freuency Many of the examples could easily have found themselves in books subtitled A Comedy of Engineering Errors or A Comedy of Programming ErrorsThe book is fine if The Riddle of the Drum you are looking for a book that shows how mathematics in its many practical applications goes wrong Having said that there are chapters that are mathsnumberstatistics oriented than others But not as many as I would have likedThe book is reasonably well written but a few too many asides to the reader for my liking A Christmas present book from a relative in recognition of my past technical careerEach 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 serious business of reading fictionNot 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 thoughThis 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 meawning But if How Sleeps the Beast. you re prepared to ditch out of chapters uickly thatou don t enjoy and move onto the next it s generally an interesting readI 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. The author explains how the misuse of math creates problems Mathematical errors often include mistaking units pounds for kilograms feet for meters and misunderstanding probabilistic and statistical statements Parker also presents examples of use. .
