Quantum
demo does tricky computing
Factoring the number 15 isn't usually a big deal.
Doing the math using a a test tube of liquid, however,

Email
burdened by management role
The humble email program has been pushed to its
limits by people's tendency to use it as their primary
information management tool. Will software makers
get the message?
Pixel
feedback forms fractals
Aim a video camera at its own monitor and you can
generate fractal patterns. Researchers have adapted
the technique to work with pixel-based monitors.
The research could provide insights into all kinds
of feedback.
Software
agents evolve purpose
