We live in a polarized world. No, we aren't talking about politics—we're talking about light. Much of the light we see and use is partially polarized, meaning its electric field vibrates in specific directions. Lenses designed ...

(Phys.org)—In a normal rainbow, red is always on "top" while violet is on the "bottom." This is true whether the rainbow is created by a glass prism or by water droplets in the sky, and is due to the way that these materials ...
Faking photographs is not a new phenomenon. The Cottingley Fairies seemed convincing to some in 1917, just as the images recently broadcast on Russian television, purporting to be satellite images showing the MH17 airliner ...
