Ye gods, things shrink...

[I hope this brief quote falls within the `fair use' bounds.]


The American Institute of Physics Bulletin of Physics News
Number 567 November 29, 2001 by Phillip F. Schewe, Ben
Stein, and James Riordon
Canada-Germany collaboration (Ferenc Krausz, Vienna Institute
of Technology, 011-43-1-58801-38711, reports that it has produced and
detected, for the first time, isolated x-ray pulses lasting on the
scale of attoseconds, where one attosecond is a billionth of a
billionth of a second (10^-18 s). The reported pulses, lasting
approximately 650 attoseconds (as) and residing in the soft x-ray
part of the electromagnetic spectrum, subsequently provided
attosecond-scale measurements of a physical phenomenon
(specifically, the detachment of an electron from an atom by an
x-ray photon).
