NEW YORK TIMES BESTSELLER - A former Wall Street quant sounds the alarm on Big Data and the mathematical models that threaten to rip apart our social fabric--with a new afterword "A manual for the twenty-first-century citizen . . . relevant and urgent."--Financial Times NATIONAL BOOK AWARD LONGLIST - NAMED ONE OF THE BEST BOOKS OF THE YEAR BY The New York Times Book Review - Boston Globe - Wired - Fortune - Kirkus Reviews - The Guardian - Nature - On PointWe live in the age of the algorithm. Increasingly, the decisions that affect our lives--where we go to school, whether we can get a job or a loan, how much we pay for health insurance--are being made not by humans, but by machines. In theory, this should lead to greater fairness: Everyone is judged according to the same rules. But as mathematician and data scientist Cathy O'Neil reveals, the mathematical models being used today are unregulated and uncontestable, even when they're wrong. Most troubling, they reinforce discrimination--propping up the lucky, punishing the downtrodden, and undermining our democracy in the process. Welcome to the dark side of Big Data.

Great fun for dogs!
Color: Orange
Two of our dogs really love this! It caused a lot of barking and chasing and running around trying to grab it. It's really funny to use the remote to control it (and especially make it stop when things get a little too chaotic!) It feels durable even when pawed and bumped into and stepped on. The battery life seems good. I plugged it in overnight to charge so not sure how long it took to charge, but it has lasted quite a while with the dogs playing with it and still doesn't need a charge. It's easy to screw off one side of the ball to plug it in to charge. The size is a little bigger than a tennis ball I would say and has a soft texture.

It doesn't work.
Color: Blue
The two halves of the ball shell come apart again and again when the dog plays with them. When it is time to recharge the core, it will not take a charge. The dog loves it, but it's unsafe to play with.

It doesn’t do what is supposed to do
Color: Blue
Wasn’t impressed..,all the ball does is vibrate. It doesn’t really bounce

My dogs fight over it
Color: Orange, Color: Orange
Easy to use, durable, and has a great battery love. At first my dogs were curious and unsure about it, now its become one of their favorite toys. They'll stare at it while its being charged and impatiently wait for it so they can have fun again. Perfect size for most breeds.

Bouncy, not hard, and good value.
Style: Fetch Balls (Pack of 10), Size: 2.5 inch
Great balls for the ball launcher and not rockhard like some of the solid rubber balls. These have great bounce, and because of the two holes, they make a fun whistling noise as they fly through the air. My dogs love them and they are a good value.
By the way, if you throw them too hard, they will go through chain-link and no climb fence because they squish a bit!
