I'm not in favour of making Greece an example; most Greece people didn't ask for the mess they are in and are hardly to blame for being ruled incompetently in the past. That said, it's complete nonsense to blame the unfortunate financial situation the country is in on Germany or the remainder of the EU. Greece has been completely incompetent in raising taxes and clientelism and corruption are widespread. I can imagine the austerity measures to be impopular, but let's not forget that the EU has been dumping hundreds of billions of euro's in the EU, in an attempt to help Greece.
Plus some microbes of course, maybe throw in some tardigrades. It just might be enough to start life 2.0, which would be a nice backup and a great achievement.
Now that we're reasonably sure Mars is barren, I really don't get NASA's "let's not pollute it" attitude anymore.
It's bullshit the navy rescued anyone here. Transported, helped - many verbs would have fitted better.
Kidney stones supposedly hurt like hell (no personal experience here), but it's not something people generally die from.
Are iPads required in that school?
Yes, at least in practice, they are.
You are overgeneralising. My youngest son goes to a school that uses iPads. The kids all take their iPad to school every day, and after one and a half year, his one is still in perfect condition, and I think the whole class had one 'accident' over that period. The school found a pretty simple solution to prevent this: the parents pay for the iPads themselves...
This is just stupid. An ipad is a specific device by a specific brand. They can tell you to bring a pencil or paper, and as long as it meets specifications, it doesn't matter what you bring. But to specify a certain brand of tablet is not right.
In an ideal world, all courseware would run on all tablets. Unfortunately, this is not the case. While in principle I agree it would be better if you could pick your own tablet, this is nearly as unrealistic as saying you could pick your own books - it's just not going to work in a school situation. I'm not happy about that. But the school we picked was clear about what tablet they'd picked, and that was the point where we could make a choice.
First of all tablets are expensive.
Yes, they are. Especially Apple ones. But so are books, and teachers. Money well spent, in my opinion.
Only rich people or people who are bad with money can afford to have them for their children. I'm sure that Obama will buy them for the poor folks. But the middle class people are then left out. They can't afford to buy one because they are subsidizing them for the poor people.
Maybe things are a bit different here in Europe, but AFAIK we have a higher tax rate here, I'm what you'd call middle-class, and I don't have any problem with buying an iPad for my children - nor with subsidizing the ones for poor people. Again, money well spent.
This is just corporate graft an d corruption to use our tax dollars to shore up an industry that is drowning in its own profits.
Let's agree he 5% educational discount Apple provides is a bit meagre
You just need decent software.
None exists to my knowledge. I honestly cannot conceive of any way you could reasonably take notes requiring fine details using your fingertips. There is a reason we use fine tip pencils instead of big bulky markers to take notes.
The MyScript Calculator app (just google it) does a decent job, for example.
Utterly useless for note taking. That is an app for processing a single equation, and not even especially bulky ones at that. Furthermore it actually is a calculator which misses the point entirely. When you are taking notes or working through a calculation you are not trying to have the computer solve the problem for you. You need to essentially make a very detailed drawing, nothing more. (an equation is simply a drawing) The best tool for this is a pen or stylus due to the standard math notation in use.
Point taken - taking math notes and using a calculator are different activities. The app I mentioned definitely won't help higher classes in taking math notes.
Still, a note-taking app with an input method like in this calculator app (which, AFAIK, indeed does not exist yet) might work just fine. The input resolution of the iPad screen as a whole is quite OK, and the lack of detail in a finger drawing can largely be overcome by accepting oversized input and scaling this down, and some good gesture recognition, as the calculator app demonstrates - just like your big bulky markers are fine for flipover boards.
Kids are just going to destroy, abuse, and lose the expensive tech.

The best thinkers in history were educated by people.
And the best teachers in the world have always used whatever tools could help hem in that. Crayons, cave walls, scrolls, blackboards, pens, notebooks, televisions, you name it. And now they have iPads.
Not to replace them, but to assist them.
Tablets for school make a lot less sense if you cannot write equations or draw detailed diagrams with them. A fingertip is simply too blunt an instrument to be used for writing equations or drawing - for that you need a stylus.
No you don't. You just need decent software. The MyScript Calculator app (just google it) does a decent job, for example.
That's nice and all but can we trust our data formats to stay static for that long?
Just use Word 95 format. Everybody seems to be able to read that somehow, and there seems to be no way to get rid of it.
There's a difference between 'not fishing' and 'not overfishing'.
Well, them eating fish eggs is not spectacular, but it can be problematic - it means that once they are abundant, it's harder for fish to make a comeback.
While the nerd im me can't help to appreciate the tech in those things that make them auto-detect and kill stuff, I'm not convinced this is a good idea at all.
Wouldn't it make more sense to fix the root cause of this problem, that is, overfishing?
Did they even consider the consequences of generating 400 kilos of dead stuff an hour? Something will probably find this a nice food source. Are we going to kill that too, and where does this end?
Are we sure it only kill jellyfish?
