A disagree for what? That the news is related to the "rotating crystal"?
According to the American Institute of Physics light was slowed back in 2001: http://www.aip.org/pnu/2001...
So what is new in the experiment from Scotland?
Please comment instead of just clicking "disagree".
Isn't this old news?
Professor Lene V. Hau at Harvard slowed light to a complete stop using a Bose-Einstein condensate years ago: http://www.seas.harvard.edu...
But maybe the news is related to the "rotating crystal"?
This reviewer agrees with you, calling it a "mixed blessing"
