Sales is a great place for people with ADD as they are often personable and funny (perhaps I'm projecting
As far as addiction goes, what of it? People are addicted, physically addicted, to coffee, and other substances all the time. It's not the addiction but the psycho-physico-emotional harm that it might do that is the problem. No one worries that people with bipolar disorder are "addicted" to their meds.
I agree, though, that the situation we have in textbooks is sort of the same as the one in American automobiles: an oligopoly where a few competitors offer roughly the same product with roughly the same prices. Add in the fact that all the add-ons and online content is almost never revenue-bearing and the price of the textbook isn't going to drop very far. Change is coming, though. I can feel it in my bones! Flat World Knowledge, Inkling, and now Apple are going to get it right pretty soon and change the way the whole industry operates. I'm just glad I work in the media department and not print!
Also, textbooks these days come with a wide range of additional print and on-line resources like study guides, course management and homework systems, videos, etc. that are usually bundled with the book for "free." (I'm not going to insult you and suggest these add-ons don't effect the price of the book, but their value generally far outweighs the price)
If you want someone to blame, talk to the people who run your local bookstores.
Seriously, though, we need a better system. Modern rocketry is almost 100 years old and we haven't come up with anything better?
Another problem with this type of representation of the 4th dimension is scale. If the 4th Dimension is time, and you want to move in the 4th Dimension to a point at which the object you're trying to circumvent, say a wall, doesn't exist, you have to go back to before it was made or forward to when it decays away. In a lot of places, any wall you're likely to encounter is older than you are which, you might suppose, would mean its size in the 4th dimension would be bigger than you. I suppose if a wall were new, you would be at one edge of it 4th dimensionally-speaking.
Anyway, I know that this game is just using the 4th dimension as a way of spicing up a puzzle game, for which I applaud them, but I would love to see a real mind-warper out there sometime. There used to be a 4D rubiks cube program, for instance that used to really tweak me out.
Their whole policy, requiring students to use only the school's computers, not allowing them to access or disable the webcams, makes no sense to me. It smells like someone trying to limit their liability, you know? Like trying they are terrified of what these students might do with these computers. Sex-picture viewing, president threatening, etc, but not in a rational risk-management way. It feels more like a witch-hunt.
Why is our culture ever more terrified of our teenagers?
1.) Just because they told the kids that they might activate the web cam to find it doesn't give them the right to do so. If the activity is illegal, telling someone you are going to do it beforehand doesn't make it legal. IANAL, but this one sounds pretty shaky.
2.)Even if they had the legitimate authority to use the web cam, once they realized that the laptop was in the hands of the right person, they would have been legally obliged to stop spying. Any information they gleaned from that spying would have been inadmissible in court.
From the posting at that link it looks like the school is on a serious freakout powertrip. Requiring the students to have one of these computers, requiring them to use them to the exclusion of all others and then spying on them periodically even if there was no report of the laptop being stolen.
The school board and school administration of that town should be burned to the ground with metaphorical salt sown in their professional fields.
