A Fold Apart: Origamist Robert Lang’s Incredible Paper Creations

(via Great Big Story)  Twenty five years ago, physicist Robert Lang worked at NASA, where he researched lasers. He also garnered 46 patents on optoelectronics and wrote a Ph.D. thesis called “Semiconductor Lasers: New Geometries and Spectral Properties.” But in 2001, Lang left his job in order to pursue a passion he’s had since childhood: origami.  Some of his work has helped pioneer new ways of applying origami principles to complex real-world engineering problems.
