Wednesday marked the second-ever TEDxCERN, the event organized by the folks at CERN, the famed particle physics research center in Geneva, Switzerland, responsible for bringing us the World Wide Web, the Large Hadron Collider, and confirmation of the existence of the Higgs boson. You know, just a few minor things.
TEDxCERN brought together a mix of experts from across the sciences and the world, people all working to answer the question: “What are the big ideas in science that will help us address tomorrow’s major global problems?” Particle physicist (and three-time TED speaker) Brian Cox served as quippy host, while more than a thousand attendees watched live in CERN’s Globe of Science and Innovation.
If you weren’t one of the lucky thousand, or were too swamped with work to catch the live webcast, don’t despair. We watched for you. And created a list of things we…

I’ve read about this on Business Insider here: Here’s One Theory About Why Cops In America Kill So Many People
The chart shown on is very interesting and so are the theories behind it.
«The FBI reports that in 2011, cops in America killed 404 suspects in acts of “justifiable homicide.”» – Business Insider
«Last year, police in England did not record a single shooting fatality, with officers across the country only firing weapons on three occasions. Cops on the street in England do not carry firearms.
In Australia, where police do carry handguns, gun control is relatively tight. Police in some states receive special training for dealing with mentally ill suspects.» – Business Insider
“We see this as a product of the continuing arms race between law enforcement and civilians that has been going on for decades.” (…) The arms race means “police officers have legitimate fears about the nature of the firepower they are confronting on a daily basis” – Business Insider
Eric Liu is on a mission to make civics “as sexy as it was during the American Revolution or the Civil Rights Movement.” As he describes in today’s TED Talk (watch: Why ordinary people need to understand power), we are at a moment of crisis in the United States. The average person simply doesn’t know how to participate in local government, and this means that clout is disproportionately concentrated in the hands of the few who do. Liu’s solution to this imbalance? That we teach everyone the basic skills of power.
As the people of Ferguson, Missouri, stand up against police brutality, the topic of how to take back civic power is on many minds. Through Citizen University, Liu is creating a shared curriculum of power that will be available soon. In the meantime, he offers up several basic skills it will include, to help anyone interested in influencing change right now.
Skill #1: Understand the system.

Big data has become so big, it’s spread beyond the tech world. When 163-year-old publication New York Times hired a chief data scientist earlier this year, it became clear that even non-technical organizations were hopping on the big data train. To successfully predict what their customers want or how they might behave, companies that know how to mine big data — also know as companies who hire good data scientists — have the advantage.
To do their jobs effectively, data scientists must do a whole lotta dirty data work. The New York Times calls it “data janitor work.” In a recent article, NYT reported that data scientists spend from 50 percent to 80 percent of their time laboriously collecting and prepping data before it can be extracted into digestible insights.
“Data wrangling is a huge — and surprisingly so — part of the job,” Monica Rogati, VP for…
