Wow, I bet you're the guy who makes laptops fail two days after the three-year warranty ends.

I am all in favour of careful engineering. Designing things to fail is extremely antisocial.

they hit 2nm resolution. That's when the quantum happy fun times really start.

... actually might be cheaper than ink ones.

If the flywheel is horizontal, it will strongly resist roll (where a car's weight moves to the outer wheels on a corner), and may improve handling significantly.

If the flywheel is vertical (very unlikely), the car will resist turning and have very poor handling.

Conservation of angular momentum is the same force that makes bikes easy to balance (slow to fall over) when they're moving.

With a spinning wheel, rotating the axis (axle) towards the plane of the wheel is hard, but rotating around the axis offers no resistance.

More reading.

I agree.

I have no idea what fraction of the population does it, but I wouldn't be surprised if more than half would, given the opportunity.

How can something that most people do be illegal? (in a democracy)

That sounds right to me.

The interpretation I like is that the superposition of states simply gets larger and encompasses the person doing the measuring. The person themselves is then in a superposition, each part believing a certain measurement was recorded.

This is just an interpretation (the "many worlds" theory) -- I don't think it can be tested any more than the fact "God"(s) exists can.

.. as long as you start with a piece of fairy cake.

What about deep-frozen pizza? Does the ISS have a microwave? ;)

Apart from the implications this might have for classical electronics, the long-term goal here is to build solid-state quantum computing devices. The phosphorus donor has one lonely electron, and that electron's spin is a good candidate for a qubit. One of the good things about P in Si is the long decoherence times -- T2 times of almost one second have been demonstrated. The phosphorus' nuclear spin of 1/2 stays coherent for hours, if we can find a way to get at it.

Of course, the NIST guys with their ion traps have demonstrated several interacting qubits, but perhaps P in Si chips might be useful as a more stable, more scalable, cheaper or smaller alternative.

Agreed. Their internet sucks too - we switched to ADSL with iinet recently (no Internode available here) and haven't looked back. Optus' upload speed is about 22kbyte/s even with 1Mbyte/s download speeds.

Optus is a good example of how not to treat your customers.

It doesn't have to be a game. Any simulation is fun to create. Especially if it is interactive.

A horizontal flywheel would be totally awesome - no matter how fast you cornered, there would be no "roll".
