#FeynmanLectureChallenge Day 10 -
In every case we find that the mass of the first object times its velocity, plus the mass of the second object times its velocity, is equal to the total mass of the final object times its velocity. These are all examples, then, of the conservation of momentum. Starting from simple, symmetrical cases, we have demonstrated the law for more complex cases. We could, in fact, do it for any rational mass ratio, and since every ratio is exceedingly close to a rational ratio, we can handle every ratio as precisely as we wish.
CBCNews - American shakedown: Police won't charge you, but they'll grab your money -
Across America, law enforcement officers — from federal agents to state troopers right down to sheriffs in one-street backwaters — are operating a vast, co-ordinated scheme to grab as much of the public’s cash as they can; “hand over fist,” to use the words of one police trainer.Everyday when you consider things like this think about the Sopranos and Boardwalk Empire and what amateurs they are compared to the government.
The Register - Sun burps MASSIVE solar storm: Expect a light show in the skies -
A "significant" solar storm emitted by the Sun on Wednesday will hit our planet in the coming hours – most likely causing auroras to appear over certain areas.
Power grids and satellite comms systems may experience some effects when the solar belch's high-energy radiation reaches and interacts with the Earth's magnetosphere, but no damage or chaos is expected.I will allow R.E.M. to express my feelings in song:
TechCrunch - Code.org Launches Code Studio, A Toolset And Curriculum For Teaching Kids Programming -
Rather than having kids pick up a language like Python or Java (as you would in a college or AP Computer Science class), Code Studio teaches the underlying concepts in programming through the manipulation of blocks of logic that, when stacked together in a particular order, move a character around a scene or draw a shape. The interface works a lot like MIT’s Scratch, though Code.org director of product Mona Akmal told me over a Google Hangout that there are a few key difference’s between MIT’s offering and Code Studio, chief among them the use of HTML5 (so it can run in most browsers) and the puzzle-based lesson plans for K-12 students.I played around with it a bit. It's fairly intuitive and actually kind of fun. I ent the link to my brother for my nephew. Maybe some good will come of it.

Ars Technica - US gov’t threatened Yahoo with $250K daily fine if it didn’t use PRISM -
"Our challenge, and a later appeal in the case, did not succeed," explained Yahoo General Counsel Ron Bell in a blog post published today. "The Foreign Intelligence Surveillance Court (FISC)... ordered us to give the U.S. Government the user data it sought in the matter."
After it lost, Yahoo was threatened with $250,000 per day fines if it didn't comply with the program. Not only that, but the government got permission to share the ruling with other companies in order to put pressure on them as well, according to a just-published story by The Washington Post.Once again my point is proven about the reliability, truthfulness, authenticity, whatever you want to call it, of the Snowden documents. When the documents were released back in June of 2013 Yahoo was listed as a willing PRISM participant, and everyone reacted with outrage. Today it turns out that they may have been coerced and they are being lionized as defenders of freedom. How many other out of context documents released by Greenwald are causing similar issues?
