The centuries-old tradition of folding two-dimensional paper into three-dimensional shapes is inspiring a scientific revolution. The rules of folding are at the heart of many natural phenomena, from how leaves blossom to how beetles fly. But now, engineers and designers are applying its principles to reshape the world around us—and even within us, designing new drugs, micro-robots, and future space missions. With this burgeoning field of origami-inspired-design, the question is: can the mathematics of origami be boiled down to one elegant algorithm—a fail-proof guidebook to make any object out of a flat surface, just by folding? And if so, what would that mean for the future of design? Explore the high-tech future of this age-old art as NOVA unfolds "The Origami Revolution."

For centuries, the Lithuanian city of Vilna was one of the most important Jewish centers in the world, earning the title "Jerusalem of the North" until World War II, when the Nazis murdered about 95% of its Jewish population and reduced its synagogues and cultural institutions to ruins. The Soviets finished the job, paving over the remnants of Vilna's famous Great Synagogue so thoroughly that few today know it ever existed. Now, an international team of archaeologists is trying to rediscover this forgotten world, excavating the remains of its Great Synagogue and searching for proof of one of Vilna's greatest secrets: a lost escape tunnel dug by Jewish prisoners inside a horrific Nazi execution site. Archaeologists discover the tunnel near Vilnius, Lithuania, which served as an escape route for Jews fleeing the Nazis during World War II.
