3D movies and TV are is increasing in popularity, but is any of it truly 3D? How true is the 3D in movie theaters? How do glassess-less 3D TVs work? Try catching a ball with one eye closed. If you find it easy, try having the ball thrown a couple of feet in front of you, or from further away. It becomes increasingly difficult when the throw is off.
Holograms are photographic recordings of 3D scenes. Unlike a camera, which captures one view through a small viewer focused by a lens, holograms capture an entire light field which allows them to recreate the 3D scene. Shimmery 2D projections, like pre-recorded Pepper’s ghost illusion, are often confused with 3D holograms.

On Feb 11, 2016 Scientists at LIGO announced that they had detected gravitational waves for the first time. In the press conference heard round the world, they showed the tell-tale waveforms indicating that huge event in which two black holes merged 1.3 billion lightyears away, had created waves that passed by the LIGO detectors and were finally heard. Einstein predicted the existence of these waves in his 1915 theory of general relativity. But it took a long time for us to come up with the technology to detect them. For one, we had to invent lasers! This video discusses why this discovery is important, what it means for astronomy, and what’s next. If you can’t tell, I’m very excited.
