They may very well remain fully in tact - but just as cruical in a crash is the deceleration rate of the occupants. The "bounce" would only serve to make this worse.
What it lacks are crumple zones which reduce the deceleration rate.
The ideal design for a safe car is a large crumple zone (=length) with a ridged cage to protect the occupants.
You can use any sort of LED you like - It basically comes down to: a) The colour you want. b) How bright you want it. c) How big you want it.
You shouldn't connect LED's straight to a battery.
You need a series resistor (In between the battery and the LED). The value of the resistor is calculated using
R = (Vb-Vf)/I.
Vb = Battery Voltage Vf = Forward Voltage (On Data Sheet) I = Current (On Data Sheet)
so for this 5mm white LED using a 9V battery Vf = 3.6, I = 30mA => R = 180 Ohms.
Make sure that you connect the LED the correct way round (The long lead should be connected to the '+' terminal on the battery, the short lead to one end of the resistor and the other end of the resistor to the '-' terminal on the battery. If you get it the wrong way round it don't worry the LED won't blow up, the LED just won't work!
"DVD" was originally an acronym for "digital versatile disc"; some members of the DVD Forum believe that it should stand for "digital video disc", due to the fact that most members of the public believe that DVD does stand for that. Toshiba, which maintains the official DVD Forum site, adheres to the interpretation of "digital versatile disc." The DVD Forum never reached a consensus on the matter, however, and so today the official name of the format is simply "DVD"; the letters do not 'officially' stand for anything.

It would be great if I had a phone which allowed my to find my friends. Of cousre the phone companies would hate it, they'd loss loads of $ on all those uncessary lengthy phone calls.
I can see that location information can be very useful, but how does it make it secure?
It is almost impossible to replicate location information and use it elsewhere to gain unauthorized entry. Even if the information is intercepted during communications, an intruder cannot replicate that data from some other place...
Why not? if I'm that bothered to gain access, surely I can cripple a device to generate bogus location information?
The main application for this seems to be medical imaging. Do you think that this technique has any advantages over other visulisation techniques? i.e. Can medical professionals spot problems easier with these images?
I believe that, in general, code is now better than ever before (through a variety of software tools and development processes). The problem is that the number of lines of code in a typical application has now also increased so that there about as many bugs per application as there were before.
An interesting exercise for undergrads. If he used a Virtex II Pro he'd have upto 4 power PC 405's on a single chip (not to mention all that reconfigurable logic).
Now some real nice research would be to see how to those processors could be combined with reconfigurable logic to give some real power.
according to the press release it isn't a new codec, rather a way of wrapping them all up:
MPV includes support for the following file types: JPEG, MP3, Windows Media Audio, Windows Media Video, MPEG 1,2 and 4 plus popular digital camera formats AVI and QuickTime MJPEG Video...
One problem with this might be the amount of time that the media will store the data without error. This seems to reduce as the density of the media increases. We can still read stuff the Greeks carved into stone, but the lifetime for data on a RWCD is probably 10years (according to the manufactures). If the density increases even further (as they are speculating) the lifetime could drop even further. Not much good if I can't look up what happened 5 years ago.

I remember reading somewhere that the number of possible positions in chess is greater than the number of atoms in the universe.
It is extrememly unlikely that you could ever build a machine to 'solve' chess (i.e. analyse every possible play). Therefore a chess computer (or a human for that matter) can never play a 'perfect' game of chess.
Therefore, any good system would also have to take into accound some sort of strategic play (fuzzy logic, A.I - whatever) - this is what makes chess programs interesting.
I'm curious to know: Do you have to get permission to launch these things? or is it a free-for-all Is there some sort of height limit? What about the UK (where I live)?
In the UK it would be classed as a Motorbike (Catergory L1e) (the motor power being over 200w). This means that it has the same legal requirements as this class of Motorbikes:
I'm no expert but I'd guess this means:
- Road tax - Insurance - Number Plate (what do you do with that?) - Lights?

The Learnabout books of the 1960s helped children to develop new interests, but these books were not strictly read by children.
How it Works: The Motor Car (1965) was used by Thames Valley police driving school as a general guide...
Well made me laugh!
I wish my PC had a built in washing machine, like the one the guy is using on page 9 'mini computer system'.
And they call it progress.
Yes it's free to call other internet phones, but this is free calls to other regular phones.
Oh except - the free calls do not include calls to mobiles, non-geographical numbers such as 0870, premium numbers or international numbers.
At least it sounds like Sony is betting both ways this time...
Add to this the fact that Sony has announced it will make drives which will read both types of HD DVD... (from the register)
DVD officially stands for nothing.

So now we know...
Well to be fair the article did only say that the surveys are out, not the results.
How fame can go to your head.
A 3D printer is always going to be more expensive than a production line (why don't they use laserjets to print books?).
However it could be extremely useful for fabricating spare parts where it would be time-cosuming/costly to get them (on a battle field, in space etc.)

Hey! the ultimate on-line sims. Totally free (well apart from taxes). 6 billion installed user base - it's called real-life.
It's open source too (just read a physics book)
Most of my mobile phone conversations consist of:
