==========
Quantum mechanics describes the bizarre rules of light and matter
on atomic scales. In that realm, matter can be in two places at once.
Objects can be particles and waves at the same time.
And nothing is certain -- only probable or improbable.
This improbable feat -- stopping light -- was accomplished by two
teams.
Not according to the article. I hate these cutesy
articles that completely distort the physics. We're still
suffering from the "fast than light" article from several
years ago. Somebody pops up with that one every few weeks.
One was led by Ron Walsworth, a physicist at the Harvard-Smithsonian
Center for Astrophysics, and the other by Lene Hau of Harvard
University's Department of Physics. Walsworth's group used warm
rubidium vapors to pause their laser beam; Hau's group used a super-
cold sodium gas to do the same thing.

And if you read the article, the photon isn't "stopped", it's
absorbed into spin states of electrons.
