Really, really excellent book on the use of Big Data in today's connected world. Author investigates policing, incarceration, schools, marketing, and the political process from the perspective of a data scientist who has seen how algorithms are used with unintended consequences. I especially like her push for the use of big data for justice and benefit to society instead of all the nefarious purposes it is put to now. Easy read.

I can say I used this years ago, warning. If you are a plumber or pipefitter do NOT use this on cutter wheels for a tool that you cut pipe with and then solder. I ended up having a blowout because of this crap in a 2 million dollar apartment. It has a really high temp rating. So if this gets on your pipe you might as well start over by cutting the joint or coupler out or look for a new job ;)

First of all, I am African-American and I swear by this stuff... along with the Joico Silk Result shampoo and conditioner, this allows me to stretch out time until my next relaxer on my 4a/4b textured hair. My hair is kinky, thick-wiry, and I have very dry scalp. This helps smooth down my hair weightlessly and infuse into it cationic hydration and botanical/marine moisturizers- not mineral oil as a cheap filler.
