Invisibility cloak now a reality, scientists say

Excerpt:

Scientists have made the impossible possible, disappearing a cylinder by guiding light around it before putting those photons back on their original path -- essentially bending light around the object. This new approach achieves invisibility where others have failed. With a catch, however: It only works from one direction. The math is incredibly complex and the materials necessary difficult to produce. And while the underpinning concepts allow invisibility in microwaves and hold promise for radar, it won't be easy to make it work at optical wavelengths, cautioned Duke University’s Nathan Landry and John Pendry of London’s Imperial College, who published their results in the journal Nature Materials. 'We built the cloak, and it worked. '- Nathan Landy, a graduate student at Duke’s Pratt School of Engineering Still, it's a breakthrough six years in the making.

Key:

  • Aggregate Sentiment is meant to be an indicator of an individual's overall sentiment.
  • The Mean is meant to be an indicator of an individual's average comment sentiment.
  • The Standard Deviation, when there are enough quotes, will indicate an individual's consistency of sentiment (i.e. a Standard Deviation of 0 would mean they were very consistent in their sentiment and 1 would mean they were very inconsistent).

Note that quote stats are likely to be meaningless beyond the aggregate score due to the tiny sample size. However, they are always provided just in case you find something useful there.
