Here's the deal. If you're a social scientist or a physical scientist (me) who works outside the world of controlled laboratory data, you have to make sense of the world with imperfect experiments. You often have limited data, you can't repeat your experiments, and the differences between your subject and control are sometimes very fuzzy. Yet you have to try to make some inferences even though imperfect data are all you have. How do you do that in an honest and careful way? That's what How Not

This is a wonderful book about mathematics and its application to everyday life. Jordan Ellenberg shows that the certainty that people associate with math is often misplaced; some areas of math are devoted to uncertainty, and that's where things get very interesting.
Ellenberg starts the book with a beautiful example of application of mathematics, logic, and thinking out of the box. During World War II, a group of mathematicians working for the Statistical Research Group were given a problem by ...more

I so wanted to like this book.
It's a topic I enjoy. I flicked through the book and the author was saying things that I agree with. Jordan clearly knows what he is talking about. All the signs were good.
So why the 3 stars? Because the book is unfortunately quite dull. There are long sections where Jordan spends ages proving some mathematical point or other, but then he doesn't draw any conclusions from it.

I math for a living. I mathed, both amateurly and professionally, at school. I math quite a bit. And as a math teacher, I like reading "pop math" books that try to do for math what many science writers have done for science. So picking up How Not to Be Wrong was a no-brainer when I saw it on that bookstore shelf. I’ve read and enjoyed some of Jordan Ellenberg’s columns on Slate and elsewhere (some of them appear or are adapted as chapters of this book). And he doesn’t disappoint.

This book was an excellent guide to the many ways in which our intuitions and poorly understood statistical training can lead us astray. One of the areas that it covers is regression to the mean, a concept which pretty much everyone needs to be aware of, since a better awareness of its ubiquity would prevent a lot of errors. Among other things, this concept explains why a successful pilot study is likely to give worse results when rolled out, why a good performance is often followed by a worse

Mathematics is a piece of music the deeper you allow yourself to understand its lyrics you will understand the practicality of it in real life. It can be a dull and unimaginative concept that only deals with some of the already established formulas. It paved a way for people to live their life hassle-free.
It brings the practicality and scientific conclusion on any topic whether it's about calculation for about judging a person. With probability and numbers, it makes us our life comfortable.

Enjoyable, entry-level book, particularly recommended to any lover of applied maths who did not get prior significant exposure to the main concepts of statistics and probability calculus.
The author writes in a very engaging and conversational manner, and his enthusiasm for maths is quite contagious; I like how he manages to compellingly convey the message that math is a creative process, not a sterile, procedural slog.

Where language and math meet is where my head explodes.
That's this book.
Fortunately, the author has a funny, down-to-earth style that keeps me going even when my eyes glaze over and start to roll back into my head. That has nothing to do with him; it's all me. He and I have a fundamental difference in wiring: he loves numbers and the things they can do. For him they sing. For me, they are instruments of torment and deceit.
Let me give you an example. Here's one from page 44 et seq., where he ...more

Makes a good case for the real world of advantages of having a mathematical understanding and how to work with math concepts. The author argues that math is a very strong version of common sense reasoning which can keep a person sharp and savvy in a complex world.
I am one of those fortunate individuals who cherishes and loves Mathematics, in all its forms. But, I know, a lot of people for whom the Maths is a dreaded specter.
Why is that so? Inevitably, this is a problem that arises from the way the subject has been taught. And this is what the book tries to dispel. This book takes us behind the numbers, equations, theories and abstruse concepts to show the practical applications of whatever we have been taught.

Almost everything that we do these days has some sort of mathematical element to it, from analysis by companies that are looking for patterns, voting, the stock market and ways of winning the lottery.
Ellenberg does make some reasonable arguments; I particularly liked the explanations on the three way voting where the favoured guy can end up being eliminated purely because of the first past the post method, and the way that groups were able to exploit a badly designed lottery.

Having come back to math in my late twenties, this book was comforting and gave me hope that learning the equations and complicated language would not be for nothing. It's also a lot of fun to read.
This is a very practical, useful, and beautifully-written book on mathematics, particularly about mathematical thinking. I learnt about this book back in 2016 from the review of Bill Gates [https://www.gatesnotes.com/Books/How-...]. Since then it had been sitting idly in my to-read list of 2017. However, I finally picked it up at the end of 17. But I wasn't paying enough "attention"! I believed in its worth but I felt I wasn't being committed enough to the contents of this book!

Is math really twice removed from our lives? Nope.
The very incredibly incredible math story from a math child prodigy (in his day), now a professor (a sensible one! a rara avis!). Fun and readable and readily comprehensible tale making math closer and WAY cooler!

“Mathematics is pretty much the same. You may not be aiming for a mathematically oriented career. That’s fine—most people aren’t. But you can still do math. You probably already are doing math, even if you don’t call it that. Math is ...more

I like math. I want to be reminded of how cool it can be, and how relevant. But all the books like this, including this, that I've attempted to read have too much explication of the maths and not enough of what it actually means. For example, a chapter will start by explaining that c + a = a +c and just a paragraph later will expect us to know what a quadratic equation is, what it means, and how to solve it.

I loved this book. Brilliant and funny as well as interesting, all mixed in with a touch of that feeling that you are actually learning something and furthering your pursuit of knowledge. 5 stars, great book recommendations throughout as well as a good aid for mathematical concept guidance. This is going in my foundation shelf and I highly recommend it for anyone who is interested in finding out many of the amazing actual world applications that math can be put to use for.

The press for this book seems a little overblown. It is decidedly not the "freakonomics of mathematics." Rather than hitting a plethora of topics, like Innumeracy and other popular books have done, Ellenberg homes in on just a few: linearity (consider: most trend lines are Laffer curves, not straight lines); inference (consider: an FBI algorithm determines that you are probably a terrorist; what are the odds that you are a terrorist? very very low; false positives almost always vastly outnumber

The most amazingly insightful yet simply written book on the importance of math in daily life, simply because math is present even in the most unassuming of places!
There are many things that I absolutely loved about the book. First, the discussion on how a Jewish mathematician Abraham Wald helped refine the strategy of placing armour on WW2 Planes with his counterintuitive yet eureka-esque approach. Second, analyses differ because of the way the math is involved i.e. linear vs. curve graph ...more

I'm definitely someone very interested in math -- I have a BA in math and I'm pursuing a Master's in Analytics. However, this book got a bit too abstract even for me. I was hoping for more examples of applied mathematics, and while this book definitely had that, there were often theoretical/abstract/historical asides that seemed distracting. I also think there was too much information about mathematicians that wasn't needed; it just detracted from the examples and things got muddled. I would

Have you ever heard the joke, "I'm an English Major. You do the math." or "There are three kinds of people in this world. Those who are good at math, and those who aren't."?
Both of those apply to me. Anyone who knows me knows that I hate math, that my mind draws blanks when it comes to anything relating to it. So why did I read this book? It was a book club selection that I wouldn't have picked up otherwise.

In the preface to Jordan Ellenberg's chunky maths book (441 pages before the notes in the version I read) we are introduced to a hypothetical student moaning about having to work through a series of definite integrals and complaining 'When am I going to use this?' What Ellenberg sets out do is to show how we use mathematics all the time - and how important it is to understand it if we are not to get the wrong idea about the world. We'll see how well he does.

It's pretty awesome trying to cram more books as the year is about to end and come across some excellent books like this one. I sincerely wish I had read it/the book had been born earlier.
Most of what Ellenberg discussed I have already familiarized myself with, unfortunately, and yet his writing is still so charming that I do not want to put the book down. He stays true to his words, writing simple yet "profound" ideas and their applications, not an easy task as I have so often observed books ...more

This book is just wonderful; funny, insightful, incredibly smart. Jordan Ellenberg lays out the ways people attempt to use math to make things seem simpler than they are, and shows many instances where math is much simpler than you might think. Even the chapter titles are engaging and memorable, like "what to expect when you're expecting to win the lottery" or "Are you there, God? It's me, Bayesian inference." If you're not certain if it's the sort of thing you'd like, try reading his article

This book is written by someone who knows his Math (being an IMO two time gold medalist (with perfect score) and two times Putnam fellow at Harvard. So one can be rest assured that he wouldn't deceive his reader when it comes to mathematical contents of the book.

My son, who is planning to major in math, gave me this book to read. Needless to say, I didn’t quite breeze through it as quickly as he did, but nevertheless greatly enjoyed it, even though I didn’t totally understand every last detail.

While math parts of this book were OK and sometimes even pretty good it has many issues.
We spend too much time on that lottery example and mostly on parts that are not related to math (why didn't state stopped lottery? If it has nothing to do with differential equations or something like that why would we care?)
But most noticeable problem is the one that you can find in many bad popular science books written in US. Basically it goes like this "Some math stuff or physics or whatever and then Hey! ...more

This book is about how one can employ mathematics to make better sense of the world. It shows how probability theory and statistics can be used to think clearly and see events in a way that is more accurate and in conjunction with their inherent uncertainty. The book also discusses the inner workings of mathematics as to how different theories are built and how we know their veracity.

Some of the topics discussed here were also covered in Nate Silver's The Signal and the Noise, but this book goes beyond statistics and probability. I especially enjoyed some of the seemingly-irrelevant digressions that Ellenberg makes about math history.
