Why do I keep seeing summaries that link to articles that are summaries of summaries of the original publication? Just link to the damn Nature article if that's the source.
Cleland and his team took a more direct measure of quantum weirdness at the large scale. They began with a a tiny mechanical paddle, or 'quantum drum', around 30 micrometres long that vibrates when set in motion at a particular range of frequencies. Next they connected the paddle to a superconducting electrical circuit that obeyed the laws of quantum mechanics. They then cooled the system down to temperatures below one-tenth of a kelvin.
At this temperature, the paddle slipped into its quantum mechanical ground state. Using the quantum circuit, Cleland and his team verified that the paddle had no vibrational energy whatsoever. They then used the circuit to give the paddle a push and saw it wiggle at a very specific energy.
Next, the researchers put the quantum circuit into a superposition of 'push' and 'don't push', and connected it to the paddle. Through a series of careful measurements, they were able to show that the paddle was both vibrating and not vibrating simultaneously.
What's wrong with teaching kids about respecting copyright?
Because schools are not there to teach our kids about respecting the law, they are there to teach them critical thinking and problem solving skills, and to expose them to knowledge... not force them to agree with it. Copyright has nothing to do with critical thinking or problem solving, and it is not the kind of knowledge that k-12 kids should be worried about in the context of schools. Don't forget, schools are not parents... no matter what the 'gumment says yo! Of course, this is just my opinion and not reality, which makes me sad. How about you?
Have any of you even read TFA? Of course not this is slashdot... The second link contains more interesting information, so I suggest everyone checks it out. But for the lazy...
Across the state and around the world, well-respected educators have designed customizable texts to meet the unique needs of their students. Federal grants have funded research that is free for public use. And now California has put out an initial call to content developers, asking that they submit high school math and science digital texts for our review. We hope the floodgates are open. We'll ensure the digital texts meet and exceed California's rigorous academic standards, and we'll post the results of our review online as a reference for high school districts to use in time for fall 2009.
First of all, this is for math(s) and science textbooks only. So don't worry about cuddling up with your English lit stuff on the couch, you can still do that. Second, this is an open call for submissions which will be up for approval. This most likely means that if there are honestly no satisfying submissions, this idea may get scrapped/postponed.
I think if these were down to earth, non-drm, popular/flexible format based ebooks that are not stuck in online-only mode and are downloadable, then there shouldn't be too many problems. Yeah, I'm curious about many of the infrastructure issues, such as delivery, storage, etc... as well as the business model that will be behind the acquirement of these textbooks. But many of the comments I've read here seemed to be really ignorant of the above paragraph which I think negates half of the concerns I've read about so far.
Last year, the state earmarked $350 million for school books and other instructional materials. Imagine the savings schools could realize by using these high-quality, free resources.
So reading further, and seeing the above statement sheds some more light on my first quote. It sounds like the state is expecting the submitted learning material to be "donated" for the cause of education. Meaning no publishers and no money involved in acquiring it. So all that's left is storage/delivery/viewing infrastructure. This is looking more promising now (just hinging on the availability of quality free educational content).
However, there are those who ardently defend the status quo, claiming our vision of providing learning materials to students for free would risk a high-quality education.
Again, more mention of FREE.
I don't live in California, but I recognize that the education system in the entire country is in shambles. I'm personally glad to see ideas like these being pushed around, and not only that but actually looking like they'll get implemented and not just talked about. While it's not mentioned explicitly, this sounds to me like it's talking about k-12 education. So all of you who only remember the university environment, please realize that k-12 is different. The textbooks were never yours to begin with. Hell, I'm from Florida and sometimes my school didn't have enough textbooks to give one to each student to take home. So yes, we only used them in class. Homework was improvised... photocopy, worksheets, etc...
Simplicity does not precede complexity, but follows it.
