S2015 E4 • Special Relativity and the Twin Paradox

How can just two rules of Einstein's 1905 theory of special relativity lead to seemingly paradoxical changes in the perception of time? This video was inspired by a special relativity class in high school. Special relativity was one of the first subjects that made me go, “wow, that’s really how the world works?!” It stretched my imagination, as I hope the twin paradox will yours.

S2015 E12 • How 3D holograms work

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.
