while reading I was wondering if what he was talking about is the standard deviation, then the author said: Experts will note that I'm carefully avoiding the phrase "standard deviation" .. I'm an Expert 😎

The fact that Pythagoreans didn't believe in irrational number is absurd!!
"So shocked were the Pythagoreans by these numbers, they put to death a member who dared to mention their existence to the public."

"And if you want to imagine what it means for twenty-six people to be killed by terrorist bombings, imagine twenty-six people killed by terrorist bombings - not halfway across the world, but in your own city. That computation is mathematically and morally unimpeachable, and no calculator is required."

Laffer curve
“All the Laffer curve says is that lower taxes could, under some circumstances, increase tax revenue; but figuring out what those circumstances are requires deep, difficult, empirical work, the kind of work that doesn’t fit on a napkin.”

The book is very interesting and like any good book on mathematics it builds on itself in a very unique way. Additionally, Ellenberg is hilarious in his examples and is doing a great job simplifying the complex mathematics.

The bigger problem is the title of the book is just flat... wrong. There's nothing about how not to be wrong. It's just mathematical ideas which is interesting but almost no application or how someone would use it. IT's a book that celebrates math, but at the same time, it doesn't teach anything just says "Math's powerful, hey I was really smart for being a mathematician wasn't I? You could be one too...."

The book started off really good, but has become a little slogging.
But worse, Ellenberg presents examples as facts and ignores either the units, or the values before hand. Such as claim Bernoulli's value for time vs money as a constant, and then solving the st. petersberg principle with that value, saying the answer is 2 rather than 2xUnit or what ever he aimed to get (which is NOT what Bernoulli said)

If you haven't read this non-fiction bestseller yet, please stop what you're doing and read it. Jordan makes math fun, again!

Knowing mathematics is like wearing a pair of x-ray specs that reveal hidden structure underneath the messy and chaotic surface of the world.

A fascinating book of how maths could apply on our everyday life to better our thinking and decision making. Yet, got lost in statistic and maths theory along the way for a math dummy like me. It's a good read anyway ,and will go over again to better understand.

que se escreve uma equação ou desenha um gráfico - você está fazendo matemática, a extensão do senso comum por outros meios.

ou que você abandona a ideia de que as crenças de grupos devem estar sujeitas às mesmas regras que as crenças dos indivíduos; e que, simplesmente, você descobre aquele pontinho cognitivo gostoso onde pode deixar a sua intuição correr solta na rede de trilhas que o raciocínio formal prepara para ela;

Toda vez que você observa que maior quantidade de uma coisa boa nem sempre é melhor, ou que você se lembra de que coisas improváveis acontecem com frequência, dadas as oportunidades suficientes, e que resiste à sedução do corretor de Baltimore; ou que toma uma decisão baseada não só no futuro mais provável, porém na nuvem de todos os futuros possíveis, com atenção àqueles improváveis;

... Matemática, a extensão do senso comum por outros meios. Quando é que você vai usar isso? Você vem usando matemática desde que nasceu e provavelmente nunca vai parar de usar. Use-a bem.

Examinador: Então, sr. Gödel, de onde o senhor vem?
Gödel: De onde eu venho? Da Áustria.
Examinador: Que tipo de governo vocês têm na Áustria?
Gödel: Era uma República, mas a Constituição era tal que acabou virando uma ditadura.
Examinador: Ah! Mas isso é muito ruim. Uma coisa dessas não poderia acontecer neste país.
Gödel: Poderia, sim, e eu posso provar.

Os amigos de Gödel, Albert Einstein e Oskar Morgenstern, imploraram que ele evitasse esse assunto no exame, mas, como se recorda Morgenstern, a conversa acabou mais ou menos assim:

Gödel, por exemplo, cujo teorema excluiu a possibilidade de banir definitivamente a contradição da aritmética, também se preocupava com a Constituição dos Estados Unidos, que estudou ao se preparar para o teste a fim de obter a cidadania americana, em 1948. Em sua opinião, o documento tinha uma contradição que permitia a uma ditadura facista tomar o poder no país de forma perfeitamente constitucional.

Efeito de dominação assimétrica: quando há duas opções de escolha com atratividade parecida, as escolhas entre as duas dividem-se, aproximadamente 50%/50%. Se surge uma terceira opção, ligeiramente pior que uma das duas iniciais, a que é ligeiramente melhor que a terceira opção passa a ser mais escolhida (cerca de 2/3 das vezes). Exemplos: parceiros românticos e bolor limoso.

Os matemáticos, desde Descartes, têm desfrutado a maravilhosa liberdades de oscilar de um lado para outro entre descrições algébricas e geométricas do mundo. A vantagem da álgebra é que é mais fácil formalizar e digitar num computador. A vantagem da geometria é que ela nos permite mobilizar nossa intuição física para encarar a situação, em particular quando se pode fazer um desenho.

I don't believe the story about armor plating planes. I've heard it before. Who in their right mind would consider plating anything but the critical parts?
