# !!> KINDLE ➜ Humble Pi: A Comedy of Maths Errors ❤ Author Matt Parker – Tactical-player.co.uk

Overall, interesting and amusingly written As a long time user of spreadsheets, however, I found the chapter on Excel worrying Years ago I read somewhere that about 50% of all spreadsheets contain errors According to research cited in Humble Pi the true figure is closer to 90% I don t doubt the figure but thought it probably only applied to the spreadsheets that I had constructed It is frightening to think that it also applies to really serious work. The First Ever Maths Book To Be A No Bestseller Wonderful Superb Daily MailWhat Makes A Bridge Wobble When It S Not Meant To Billions Of Dollars Mysteriously Vanish Into Thin Air A Building Rock When Its Resonant Frequency Matches A Gym Class Leaping To Snap S Hit I Ve Got The Power The Answer Is Maths Or, To Be Precise, What Happens When Maths Goes Wrong In The Real WorldAs Matt Parker Shows Us, Our Modern Lives Are Built On Maths Computer Programmes, Finance, Engineering And Most Of The Time This Maths Works Quietly Behind The Scenes, Until It Doesn T Exploring And Explaining A Litany Of Glitches, Near Misses And Mishaps Involving The Internet, Big Data, Elections, Street Signs, Lotteries, The Roman Empire And A Hapless Olympic Shooting Team, Matt Parker Shows Us The Bizarre Ways Maths Trips Us Up, And What This Reveals About Its Essential Place In Our WorldMathematics Doesn T Have Good People Skills , But We Would All Be Better Off, He Argues, If We Saw It As A Practical Ally This Book Shows How, By Making Maths Our Friend, We Can Learn From Its Pitfalls It Also Contains Puzzles, Challenges, Geometric Socks, Jokes About Binary Code And Three Deliberate Mistakes Getting It Wrong Has Never Been Fun This book was a bit of a let down The examples actually based on maths might have made a good magazine article, but instead we have a book typeset in a big font and padded out to over 300 pages There are some interesting examples of fences and posts problems, binary numbers wrapping round to start again at 0 in computers, properties of random numbers, and errors of units and combining different levels of precision That s most of the maths To make the book interesting and longer, the author then has to borrow from other disciplines like product design, human factors and management science A mechanic confusing two sizes of screws on an aircraft, and the process failures that allowed this to ever happen, is not really maths , and nor is having badly designed fire doors on a building that open inwards and jam shut in a crush Maths may be the queen of all sciences but that doesn t mean it can appropriate from other disciplines to try and make itself interesting, without giving any credit Instead of this book, buy The Design of Everyday Things by Donald Norman it s much better Two stars because this is about 2 5 of a book of interesting maths examples, and 3 5 of padding appropriated from other disciplines, because apparently there isn t enough interesting maths to make a whole book That s a shame, as the idea of the book was appealing, which was why I bought it. This superb book should be read by EVERY Engineer or Planner or Specification Writer or ANYONE who has ANY input whatsoever into the specification design manufacturing delivery process It is eminently readable and comparisons to personal everyday life are easily made It is frightening how easily little things can be missed, and can then cause loss of life He refers to a number of specifics in the medical, automotive and aerospace fields, however the points he is making apply to almost everyone everywhere If I could have given it 7 or 8 stars I would have READ IT Please A very interesting and enjoyable book about the application of mathematical concepts and quirks to real world events A lot of the examples relate to problems in programing software and engineering The emphasis is less on the maths and on the errors Great fun and worth a read. I listened to this whilst commuting and found it very interesting and calming Matt reads his book very well I especially liked the attempt to redefine the Parker square at the end. This is a fun book It s enjoyable and makes you want to keep reading even though you really need to get up early tomorrow.But it s not as good as Things to Make and Do in the Fourth Dimension.This book does show how failure to understand maths can cause horrific problems, be it mass deaths, loss of billions, or having your pilot nearly sucked out of the aeroplane cockpit But if narrowly averted catastophe is your thing you d be better off reading Rachel Maddow s Drift.In the end, I think the problem comes down to two issues First off, is trying to put comedy and tragedy together, and secondly there s simply not enough maths in it There s a bit of talk about how various things work, but little in the way of equations or in depth exploration Things are limited in the real world, and those limitations make maths less interesting.If you enjoy Parker s other work you ll likely enjoy this, but you won t be blown away by it. Really interesting book which covers various ways problems have been caused by maths errors The book is written in a lighthearted way and very enjoyable even if you don t have any particular maths knowledge although as a mathematician I would also have enjoyed some problems to solve.Only negative thing to say is that I was so engrossed I read it all really quickly and would like some please.
