Ver DNA testing medical screening results and historical events such as the Chernobyl disaster and the Amanda Knox trial Readers will finish this book with an enlightened perspective on the news the law medicine and history and will be better euipped to make personal decisions and solve problems with math in mind whether it’s choosing the shortest checkout line at the grocery store or halting the spread of a deadly disea As a math nerd I am always looking for books that provide insight into the use of mathematics in our lives I skimmed through this book and found some interesting tidbits on disease exponents and statistics The examples and stories include a lot of visuals which helps but there is a lot of detail here than I personally needed since I was reading this book for fun

Lives ✓ Kit Yates – Insolpro.co.uk From bTes hidden principles that can help us understand and navigate the chaotic and often opaue surfaces of our world In The Math of Life and Death Yates takes us on a fascinating tour of everyday situations and grand scale applications of mathematical concepts including exponential growth and decay optimization statistics and probability and number systems Along the way he reveals the mathematical undersides of controversies o I was never very good at math growing up in China where I never fully understood why I needed to do the proof of euations in math classes Now as a professional I am doing a job which forces me to work in math a lot Slowly seeing the magic of math everywhere from pharmaceutical to industrial production from sales to oil and gas and see the value math brings I started to appreciate it a lot This will be a book I want to send as a gift to my kids and my nephews to get them see the power of math in everyday life from when they are little I want them to understand that math is a powerful tool when you use it wisely it produces society with great impact If you didn’t use it right it could blind people and lead to huge loses and unfairness or cost lives below are just some notes I made for myself There are seven chapters in the book1 Thinking ExponentiallyUncover the connection between exponential behavior with everyday phenomena eating snacks bacteria growth deposit in bank credit card late payment Pyramid scheme nuclear reaction ice bucket challenge and population explosion This has made the point very clear that the rule of exponential growth can be seen everywhere in life2 How math makes medicine manageableLots of the medical tests are imprecise eg23andMe and the BMI breast cancer test sometimes the high false positive will make people uestion the cost benefit balance of the testscreening programs Knowing these shake the unuestioning attitude towards the accuracy of health test for us even extremely accurate test can be hugely imprecise This chapter really reminded me of the broad brushed percentile record the doctors gave to me and my husband when we were doing ultra sound test during pregnancy ecological fallacy and reminded me the time when I have my baby did x ray suggested by a dentist which now I think might have done her harm than discovering any true problem 3 Mathematics in the lawThis is probably the saddest chapter in the book with Sally Clark’s story told through the chapter The author discussed several problem with the case ‘guilty until innocent’ the wrongly calculated ’73 million to one’ probability the ‘independence mistake’ and the ‘ecological fallacy’ ‘the prosecutor’s fallacy ‘blinded by math’ 4 Debunking media statisticsThis is the chapter that I relates to the most The author has describes cases where media manipulate data One example is Lancôme’ad for its anti aging line pseudoscience There are also cases where the media fudging the headline to make their story stands out or create fake news The author suggests that “ultimately the degree to which we believe the stats we come across should depend on how complete a picture the artist paints for us If it is a richly detailed realist landscape with context a trusted source clear expositions and chains of reasoning then we should be confident in the veracity of the numbers If however it is a dubiously inferred claim supported by a minimalist single statistic on an otherwise empty canvas we should think hard about whether we believe this truth”As a practitioner I also know how easy it is to manipulate result or present it to bias people’s’ view It always benefit one party or another to put a spin on a particular finding to suggest correlation to promote argument or advance someone’s agenda We need to be really careful o being too readily to be convinced Let’s be skeptical and ask for explanation before start to draw any conclusionNot only media consulting service sometimes also have slants on stories when it comes to interpreting numbers or reporting facts They may even call it the art for science So again knowing that “Statistics can be cherry picked to present a particular angle on a story” The author has done a great job ‘help to demystify the tricks traps and expose mathematical manipulations employed Rather than perceiving them as indisputable facts There are also some practical tricks we can use to get free drinksfood from bets Like how many people do you need in a group to find one pair who share the same birthday which I find very interesting 5 Number system6 Optimization algorithmIn this chapter the author described one of the 7 millennium prize problem N vs NP hard ‘It is often easier to verify a correct solution to a problem than it is to produce the solution in the first place The P vs NP challenge asks whether every problem they can be checked efficiently by a computer can also be solved efficiently For example once a jigsaw is complete it is easy to check that it has been done correctly More rigorous definition of what efficiency means are expressed mathematically in terms of how uickly the algorithm works as the problem gets complicated when pieces are added to the puzzle The set of problems that can be solved uickly is called Ppolynomial time A bigger group of problems that can be checked uickly but not necessarily solved uickly is known as NPNondeterministic Polynomial timeOne of the NP uestion is ‘Travel salesman problem and vehicle routing’ • ‘The yes no decision version of the traveling salesman problem is known as NP complete A powerful theorem tells us that if we ever come up with a practical algorithm that solves one NP complete problem then we would be able to transmute this algorithm to solve any other NO problem proving that P euals NP Since almost all internet cryptography relies on the difficulty of solving certain NP proving P euals NP could be distorts for our online security’• ‘Ironically some of the most astounding scientific discoveries have relied enormously on the creative thinking of highly trained and dedicated individuals If P euals to NP then computers would be able to find formal proofs of any mathematical theorem that is provable Many of the greatest intellectual achievements of humankind might be reproduced and superseded by the work of a robot At its heat P versus NP is the battle to discover whether human creativity can be automated’Other problems described here are• Dijkstra’s algorithm— finds the shortest path in polynomial time • Optimal stopping Hiring problem the 37 percent rule only works 37 % of the time but better than 10 % • I like the argument the author made on how the algorithm can be biased and we need to be aware ‘Even the genuinely pragmatic algorithm have hard coded biases they influence the direction in which the spotlight is shone on the global stageWe place trust in supposedly impartial algorithms because we are wary of obvious human inconsistencies and inclinations But although computers may implant algorithm in an objective manner following a predefined set of rules the rules themselves are written by humans These programmed might hard code their bias consciences or unconscious directly into the algorithm itself obfuscating their prejudice by translating them into computer code’ Several examples are provided here include automated pricing strategy and Navinder Sarao algorithm to spoof the market in 2010 7 Mathematical epidemiology This chapter is about how math is used in controlling and understanding epidemics There are also some interesting points that ‘the SIR model illustrates the importance of not coming in to work when unwell If everyone with an infectious disease followed this practice we would all benefit This is the author’s argument for the harm of presentism and he used Chipotle’s case where their stuff who felt under the weather but still kept coming which ended up infect hundreds of people as exampleOther story in this chapter also includes offering HPV vaccination to homosexuals to be cost effective
