Hey Dave,

Couldn't let this thread sit idle any longer. Here's something that will change the world. Maybe not tomorrow, but someday.....

ULTRAFAST LASERS: Strobe Light Breaks the Attosecond Barrier (p. 1627)
---------------------------------------------------------------------------
Robert F. Service

On page 1689 of this issue, physicists report creating the fastest strobe
light ever made, with individual pulses lasting just 220 attoseconds, or
220 billionths of a billionth of a second. These unimaginably short pulses
are the first to be confirmed as breaking the attosecond barrier, a goal of
high-speed-laser researchers for nearly a decade. Such pulses may one day
serve as an ultrafast camera, allowing researchers to freeze action and
perhaps to spot the gyrations of individual electrons whirling around an
atomic nucleus.

Full story at sciencemag.org

Now about that light at the end of the tunnel....

R. :)
