About this deal

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.

A local reporter with a flair for the dramatic took the opportunity to fry some eggs by placing a pan in the hotspot.Pero me encantaron los capítulos de ingeniería, geometría, probabilidad, aleatoriedad, estadística, sesgos etcétera. 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.

I was thinking some of my maths teacher friends might enjoy it and find it useful for illustrations in class. People at the top of the building felt it start to shake, as if someone had banged the bass and turned up the treble. Misplaced decimals, misunderstood calculator quirks, bridges and buildings that resonate at unfortunate frequencies, and everyday folk who lack the understanding of how to divide numbers with units, make up many of the fascinating anecdotes in this book. When a disaster occurs, it is a system-wide failure and it may not be fair to find a single human to take the blame. In 1940, the Tacoma Narrows Bridge was nicknamed Galloping Gertie and it collapsed four months after being built.Of course there are the big stories, from NASA disasters to the risks of trying to crash onboard systems on planes mid-flight. 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. El libro se subtitula "Cuando las matemáticas fallan en el mundo real", pero solo una pequeña parte de lo que cuenta va realmente de matemáticas. 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.

The area looks as safe as safe can be … until you check the LAPD’s online map of reported crime locations. Whenever a computer cannot decipher a location, it still has to fill something in, and so 0,0 became the default location. Originally a maths teacher from Australia, Matt Parker now lives in Godalming in a house full of almost every retro video-game console ever made. La mayor parte son fallos de diseño ingenieril, negligencias de diseño ingenieril (hay un puente que hacen mal a sabiendas a pesar de que conocían que los cálculos estructurales estaban mal antes de empezar a construirlo, fallos informáticos y un montón de datos curiosos pero inútiles acerca de mil disciplinas, eso sí, relacionadas todas con las matemáticas. Some of the ancient Sumerian records were written by a person seemingly named Kushim and signed off by their supervisor, Nisa.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 book covers a range of mistakes, including bridge failures, space exploration disasters, game show cheats, financial algorithms gone rogue, and so much more.

Matt Parker had me thoroughly enjoying this collection of situations where maths and numbers go wrong in everyday life.

Parker takes us through some of his favourite, or some of the more noteworthy, cases of maths going wrong across a variety of applications. When you set up a new database, or a way to input data, it’s good practice to test it and make sure it’s all working. The 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.
