Microchip
electronics gave us computers, and lasers-on-a-chip
gave us high-speed telecommunications. Moving
clouds of atoms around the surface of a chip
opens the door for another technology revolution.

Email
takes brainpower
Dashing off a quick email message sure is convenient
but it may not be as easy as it seems. Getting an
idea across to your co-worker by email takes more
cognitive effort than telling it to him face-to-face.
Teamed
computers drive big display
Tie together a bunch of computer processors and
you can get a lot done, including turning huge scientific
data files into readily understandable images.
Holograms
control data beams
Filling a room with pulses of infrared light is
one way to set up a wireless network, but bouncing
light beams off the walls makes for poor reception.
Scattering the infrared beams through a hologram
clears up the picture.
Pressure
produces smaller circuits
Chip makers are under pressure to make faster computer
chips. Forcing tiny pieces of metal into microscopic
cracks could be the answer.
