Charles Koch wants to find 'common ground' with Obama administration
http://finance.yahoo.com/news/charles-koch-is-really-a-liberal-compromiser-201545347.html

Wonders never cease.

Wow. He almost sounds like Bernie Sanders in that interview.

Andy Serwer; "Is there too much money in politics, and, is it ... because rich people are putting too much money into politics"?
David Koch; "No, it's because of corporate welfare".

Bernie Sanders; "In 1995, I introduced HR 2534, the Corporate Responsibility Act, which contained many of these provisions. While the fight against corporate welfare has been led by progressives in Congress, we've also had support from honest conservatives who are rightfully appalled at this waste of taxpayer dollars. As a result, the concept of corporate welfare is now filtering into the mainstream, and some legislation has been passed which is beginning to chip away at this outrageous waste of money".

TIL that I was right to be suspicious of the motives of these Koch brothers.

TIL that the "tare weight" of one of my 3 yellow recycle bins is 1.86 kg.

Somewhat trivial, IMHO, for the rest of humanity.

But, I required this knowledge, for one of my ongoing science experiments.

Anyways....., I became curious where the word "tare" came from, and why it was spelled so goofily:

per wiki; "The word tare originates from... Arabic طرح ṭarḥ, lit. "thing deducted or rejected," from taraha "to reject""

Today I learned that the unlikely state of North Dakota has the lowest unemployment rate of any state in the country. The reason: The North Dakota Oil Boom. ND is now the largest producer of oil of any US state except Texas.

https://en.wikipedia.org/wiki/North_Dakota_oil_boom

This boom has radically changed things in the once-sleepy state:
The industrialization and population boom has put a strain on roads, water supplies, sewage systems, and government services in the area. Some counties have increased in population by almost double from 20,000 to 40,000.[9][10]

The boom has brought with it increases in crime and social problems.[16][17] The addition of thousands of oil workers has led to a housing shortage, requiring the construction of camps for housing them. Law enforcement agencies have reported sharp increases in offenses, particularly violent crime,[18] drug trafficking,[19] gun crimes,[20] and prostitution.[21][22][23] These problems are similar to those found in other regions in which energy industry workers have taken temporary jobs.[21] A 2012 report indicated that conditions were improving.[16] As of October 2013, the FBI's Project Safe Bakken had stationed additional full-time agents in the area.[22]

Yeah. I know a guy who works there. He told me that rigs producing oil are required to spend $300,000 a day. ? "It's not easy to do that," he said. Fracking adds about 300 million dollars a DAY to the US economy. Yeah. I know a guy who works there. He told me that rigs producing oil are required to spend$300,000 a day. ?
I don't get it. Required by whom, and why?

Fracking adds about 300 million dollars a DAY to the US economy. Required to spend ? care to elaborate please :) His company required the drill operators to spend$300,000 a day on goods and services once it was producing.

Before it began producing they had to spend only \$40,000 a day.

It doesn't make sense to me either. The only way I can explain it is that upper management owned drilling supply companies on the side and were seeking to privatize a big chunk of the profits.

Upper management is often corrupt. Read a biography of Henry Ford II if you want to know about it.

If they get cleaning the rooms done properly by robots, why limit it to that hotel?
They have their phone numbers for public orders and inquiries, you can call and ask them.

Brielle, an adorable 3-year-old girl from Salinas, Calif., went on “The Ellen DeGeneres Show” earlier this week. She dazzled both the crowd and the host by accurately reciting the periodic table of elements during a quiz using pictures and abbreviations. She could even provide descriptions and uses for the elements.

She knows the names of presidents, state capitals, countries in Europe and Africa, and the periodic table. Pretty impressive. I didn't learn the periodic table until I was 10.

Today I learned that there are people who think that Portugal is part of Spain, and that Ireland is part of the UK.

EDIT I think Bush II once referred to "the unification of North and South Germany" during one of his meetings with Angela Merkel. Maybe he also referred to the unification of Eastern Korea with Western Korea. Not so funny given he has access to nuclear bombs and would be good for him to know what's what.

Today I learned that 94% of US adults can find their country on a map of the world. 30% can identify Iran.

The LHC is colliding lead ions at a new record energy.

Today I calculated: the energy in a single collision would be sufficient to lift a pen by 1mm (1/25 inch for those with a weird unit system). That is a macroscopic quantity, packed into a single nuclear collision.

Today I learned that the red fox habitat is expanding into the arctic fox habitat and the red fox will eat the smaller arctic fox... :S

Yes, I think I heard something about it....in Fox news.

Today I learned how to remove a chuck from a drill:

The information that the holding screw inside the chuck is left-handed was invaluable.

Today I learned that four rare earth metals Yttrium (Y), Terbium (Tb), Erbium (Er) and Ytterbium (Yb) are all named after Ytterby a town in Sweden.

I learned that snakes, worms and spiders are tailless.

Today I learned why we get goosebumps. I always took it literally and assumed it was because a goose's hair will fluff up when it's cold, but It's actually because we evolved from animals with fur and when you have fur getting cold is somewhat alleviated by causing your hair to fluff up. We make the same motion (goosebumps) we just don't have any fur to stand up. Same reason as geese really but not the right derivation.

Also fright seems to cause hair to stand up on some animals necks so we sometimes get them on our necks when we see something frightening.

Yes, the technical term for "goosebumps" is piloerection:

Medical Definition of PILOERECTION. : involuntary erection or bristling of hairs due to a sympathetic reflex usually triggered by cold, shock, or fright or due to a sympathomimetic agent.

Cool. Thanks.

TIL it's hard to tune a lecture to the students needs when you have both students with dyslexia and dyscalculia.
The first benefit often from a schematic way of summarizing the contents using fewer words/full sentences.
While the latter not only have trouble with arithmetic but also with visual insights.
This means they can have trouble with a schematic way of representing the contents.

Quite the conundrum when trying to (fine-)tune a lesson.
