of miles to share a virtual drawing. A new
tool, however, makes the same thing possible
with ordinary pen and paper. A camera-and-projector
rig blends the actual and the virtual.

Quantum
current closer to computing
Computers are like any other device you plug into
a wall outlet -- they run on electric current. But
that could change if the field of spintronics takes
off. Getting a bunch of electrons to spin in the
same direction as they flow from one semiconductor
to another is a big step in the right direction.
Correction

Successful speech recognition software is a matter
of different strokes for different folks, especially
if pen strokes are in the mix of correction methods.
Software
spins tales into animations
Telling it to the judge could leave her watching
cartoons -- at least if you're describing a car
accident.
Watched
quantum pot boils slower
If you blink fast enough, you can slow the inevitable
escape of trapped sodium atoms just by watching
them. Blink a little slower and you speed up their
escape. What does this portend for quantum computing?
