There may be 40 things called string theory, but they all boil down to a few things:
- point particles are actually vibrating strings
- there are extra spatial dimensions
- there isn't much in terms of specific testable predictions made by string theory
The LHC tests may show things that hint at extra dimensions (of small but testable size, not planck length). This in and of itself wouldn't prove any of the individual string theories. But showing nothing that could indicate super symmetry or extra dimensions or other 'stringy' things would be an issue for strong theory.
Disclaimer, I am not a physicist (string or otherwise).
Seems like the easiest thing in this situation is to have the ability for someone on the ground (flight control, the airline, etc.) to be able to override any locks on the cockpit and open the door. Just put some sort of satellite communication device outside, near the door of the cabin.
This would be available in a situation like the Germanwings flight, or if the pilot became legitimately incapacitated.
Their management tools are transitioning, slowly to web based. There are tasks that ONLY work in the web client now but there are also tasks that ONLY exist in the Windows only desktop client.
If you're only running guests, then you can get away with the slow web client. If you're managing the hosts you need to use both, for different things now.
The biggest challenge however is one that both Apple and Google face: Only a small fraction of the 10 million or so retail outlets in the U.S.â"220,000 at last countâ"have checkout readers that can accept payments from either system.
That is definitely true, but most credit card readers in the US that do not support EMV (aka Chip & Pin or Chip & Signature) have to be replaced if the merchant doesn't want to bear the liability for fraudulent transactions.
The liability for compromised cards is shifting in October of this year (aside from some unattended systems like gas pumps which happen later). If a merchant does not support EMV and an EMV card is compromised or used fraudulently, the merchant is liable.
Many of the new EMV capable terminals are also capable of NFC/contactless transactions. It will get a lot more of the physical readers out there. Whether the payment processors/acquirers support it is a different question.
I don't see them as customer-centric as much as self-serving. There is definitely a trend of non-US companies moving or thinking of moving their data off US servers. Moving them off US company/subsidiary servers in other countries is a huge threat to Nadella's cloud-focused Microsoft.
It is a rational self-interested decision that may be good for consumers.
Yes, Time Warner, Inc (what this story is referring to) is a different company from Time Warner Cable (which Comcast is looking to acquire).
Its also different from TW Telecom (formerly Time Warner Telecom, which is being acquired by Level 3.
Its a complicated mess of mergers and spinoffs...
Therein lies the problem. What should it be based on? How many students pass? Standardized test scores? How about teachers that are good but get a job at a school whose students are generally poorer-performing vs teachers that aren't as good but work at a school with a higher caliber of students?
Oh - I completely understand that it is a difficult question. Many of the evaluation options thrown out by people involve more standardize testing (which will favor students, and in turn teachers in better socioeconomic classes and with less English language learners).
I'm not an educator myself, but I think an honest review for tenure purposes would have to consist of a comparison of student results from year-to-year, not just comparisons between students district/state/nation-wide. Then you could possibly see how a teacher has had a negative or positive (or net-zero) effect on student progress in their subject area.
But again, this is my own layman's guess.
There are important reasons for tenure in K-12 education, especially in this era. K-12 schools (and in turn teachers) in many areas receive incredible pressure from parents. It used to be if a child got poor grades the teacher wasn't the one blamed. Now there are many parents who have spoiled brats who they believe can do no wrong.
That being said, tenure's protections should exist but should make teacher's positions far less invincible than they are in many areas now. There should be a process of discipline and removal for poor teachers. It should be as objective as possible so as to avoid undue parental pressure.
Otherwise it creates a perverse incentive for teachers to inflate grades of their students.
All the coverage I saw (from astronomy writers, NASA, etc.) said there was definitely a chance of it burning up.
If the non-science media hyped it up somewhat, well they do that for everything. Yes, I a (and many others watched for ISON). Yes, we were disappointed, but no one should have been surprised.
Assuming Gabe is being truthful when he states that this is a secondary check triggered by some other evidence for cheating, then just visiting these sites wouldn't be enough.
Its suspicious activity (reported by players? detected through other methods? not sure) that triggers the additional check(s).
the point is to take students who's parents care from bad schools and put them in an environment where they can get a decent education.
Its not always about level of care the parents are providing but what they can provide. How much care towards education can a low-income single parent working two full time jobs provide?
What is the parent doesn't have a great education themselves and aren't able to help their child academically (and only motivationally)?
Should that child suffer, not only because of that, but because of dwindling resources in the public school system that are being drained by the charter schools?
The students who are struggling are the ones who need the best resources/teaching/etc. If charter schools are as great as they are made out to be - they should be VOLUNTEERING to take students who are struggling academically, not shunning them like lepers.
