## Weapons of Math Destruction: How Big Data Increases Inequality and Threatens Democracy by Cathy ONeil

**A former Wall Street quant sounds an alarm on mathematical modeling—a pervasive new force in society that threatens to undermine democracy and widen inequality.**

We live in the age of the algorithm. Increasingly, the decisions that affect our lives—where we go to school, whether we get a car loan, how much we pay for health insurance—are being made not by humans, but by mathematical models. In theory, this should lead to greater fairness: Everyone is judged according to the same rules, and bias is eliminated. But as Cathy O’Neil reveals in this shocking book, the opposite is true. The models being used today are opaque, unregulated, and uncontestable, even when they’re wrong. Most troubling, they reinforce discrimination: If a poor student can’t get a loan because a lending model deems him too risky (by virtue of his race or neighborhood), he’s then cut off from the kind of education that could pull him out of poverty, and a vicious spiral ensues. Models are propping up the lucky and punishing the downtrodden, creating a “toxic cocktail for democracy.” Welcome to the dark side of Big Data.

Tracing the arc of a person’s life, from college to retirement, O’Neil exposes the black box models that shape our future, both as individuals and as a society. Models that score teachers and students, sort resumes, grant (or deny) loans, evaluate workers, target voters, set parole, and monitor our health—all have pernicious feedback loops. They don’t simply

*describe*reality, as proponents claim, they

*change*reality, by expanding or limiting the opportunities people have. O’Neil calls on modelers to take more responsibility for how their algorithms are being used. But in the end, it’s up to us to become more savvy about the models that govern our lives. This important book empowers us to ask the tough questions, uncover the truth, and demand change.

Mass of about one is completely meaningless. You need to provide units to give that number meaning. Regardless of that, I don't understand your question. Who cares what the mass of your text book is? I'm excellent at integrating. No, math book is a common noun; the proper noun would be the name of a specific math book or a title using the term math book. Depends on the math book.

A pile of identical books has a mass of 30 kg. Find a the mass of books and b the number of books that has a mass of 20 kg. First Name. Length 5. Find total surface area of solid cube of volume: 3. Find ratio of. I am sorry.
