do you have any idea how many of these are sold in toy stores? it's a common thing- from knock off tamagotchis to 'gamestations' that cost $20. it's a total non-story. it would be a story if walmart had advertised these items as wii accessories, but they didn't.
"In fact, hard disks were the *first* nanotechnology we ever used, anywhere."
not true. given modern nanotechnology research in to things like quantum dots, gold nanoparticles are the first nanotechnology. gold nanoparticles have had a controlled dimensionality for more than 200 years officially, and controlled size nanoparticles have existed for thousands of years- look at the lycurgus cup http://www.britishmuseum.org/explore/online_tours/museum_and_exhibition/the_art_of_glass/the_lycurgus_cup.aspx
HDDs are the first commercially marketed items with that sort of dimensionality perhaps.
adding a colouring agent would damage the very semiconductor properties you were after- the silicon currently used is incredibly pure, with only a minor imperfection to cause the "holes". if you wanted another colour, another coating would need to be added
Try any book by Haese and Harris http://www.haeseandharris.com/home.asp
They do all of the textbooks for south australian mathematics, very clear, very well laid out. just be carful, I think american highschool year 10 maths is closer to australian year 9.
I know they both aren't entirely scientific, but Mythbusters and in the UK Brainiac could be a good start, for inspiration and thinking about the scientific method. in fact, mythbusters is a good one- get the students to research a myth then plan how to bust it.
The advantage of CDS, or at least full album's worth of mp3s as opposed to singles is the sense of the album itself- an album is something constructed, not a bunch of tracks thrown together. I still buy CDs (not new releases) because I like the feeling of an abum as a whole, even If the first thing I do is rip it for my iPod
Actually, the speed of light in a vacuum is not constant at all, according to several current theories. Professor R.T. Cahill's process physics theory(i mention this one, cause i've had some lectures on it, but there are others) states that the speed of light is actually inconstant, and depends on the flow of space around it. I don't claim to understand it, being a humble chemist, but it's interesting stuff
http://www.arxiv.org/abs/gr-qc/0203015 for a cahill paper
forgive a foreigner for asking, but do you guys have any sort of Vocational Education topics? in South Australia, there is the VET (Vocational Education and training) topic offered in years 11/12 which are run in conjunction with TAFE. this allows people who are not university material (plus, unis are funded differently, no big upfront payments) to start learning a trade through an apprenticeship or traineeship whilst still below the school leaving age.
as a student in a nanotech degree, I have to laugh at the conjectures here. all of these comments about "grey goo" and self replicating "nanites" are pure alarmism. Drexler himself doesn't believe it's possible. and as for all of this screaming about the control of nanomaterials, powder technologies are only a very small part of the whole nanotech research area. most of the research that I've come in to contact with has been focused not on powders but on surfaces and coatings, or biomedical sources, which is where all the money is
and Prey is horribly bad. the situation described, as well as many of the properties attributed to nanomachines, is complete fiction. problem is, it's believeable to non-scientists. when talking about nanotechnolgy to non-scientists, I either get "what is that" or "you'll kill us all, grey goo." it's actually a damaging book, in that it actively attempts to hobble a science before it was anywhere near that level of complexity.
Actually, you ever heard of selective availability? when the GPS was first designed, it was designed to be deliberately inaccurate for civilians, and america reserved the right to switch it on and off, at least until Clinton ended that, which made the GPS more accurate. in the event of a war, however, the US can switch selective availability back on. that's one of the reason a single system is not necessarily the best
erm, as anyone working in a retail environment will tell you (especially checkout people), the cash economy is still alive and well. people still buy with cash. I'd estimate that 85% of the transactions I handle at my job (a toystore) are cash based, witht the other 15% containing credit cards, EFTPOS cards, cheques and vouchers. cash isn't dead yet, and paying with cash gives you the advantage of not being charged copious interest.
hang on, this is essentially a medicare card , not a gestapo ticket. what part of "but will not be forced to carry it at all times" doesn't click here? the good part is "The new "smart card" will contain "enhanced security" and replace 17 existing cards" so I would think that makes identity theft harder. given that as an australian citizen I'll have to carry one, it's not that big a deal. in fact, if it could be used as a drivers licence as well, or a student ID, so much the better. I don't see an ID card- of which I already carry two- as a "huge threat to civil liberties"
On a darker note, terrorist search powers are pretty big anyway, so I don't see what a card will do in a fight against terror.
hang on, this is essentially a medicare card with biometric stuff, not a gestapo ticket. what part of "will not be forced to carry it" doessn't click here?
I know that in Australia, technically it is illegal, but no one will arrest you or fine you for it. same with ripping CDs. legislation is coming so that these two will be legal.
Hang on, don't Music Companies have a right to protect some of their content? I know most companies go overboard, but it doesn't assume you are a criminal. Most people will acquire music from iTunes and use it as the DRM lets them- do you really need it playing on more than 5 machines. it is merely there to stop the person from uploading it to every tom, dick and harry on the planet. and as a foreigner, I may not know the intricacies of your constitution, but how is it unconstitutional?
depends what you define as nanotechnology. IBM use nanotech researchers, new chip carrying cases contain carbon nanotubes, and copanies like advanced powder technologies use "nanopowders" for various purposes.
"major researchers at renowned universities"- there's the problem. technology like this needs to be more widespread before it gets taken up. not all universities (or private enterprises) can buy this stuff easily. especially when you are in australia, and the government is trying to overregulate the universities...
as someone who'll be working in this field in the not-too-distant future, this could be a tremendously useful device. anything that allows a moving image is tremendously useful, and if this is as sensitive as they say, it will become a standard tool.
my question is, how much will it cost? if it's prohibitively expensive, it's usefulness is limited.

Michael Crichton may have got pack hunting right, but he got nanotechnology (Prey) and climate change (State of Fear) wrong.

Space Nazis are the most evil conspiracy ever! I blame them directly for the TV show big brother. pure evil!

either way, the democrat race is between two grammy award winning artists... bet that's a first
Robert Rodriguez isn't a guild member, most studios won't hire a non guild director. It's why he dropped out of "John Carter of Mars"

anyway, as a south Australian, I'm not of convict descent! only the eastern states were penal colonies- a long time ago.
