Sexuality and gender play a profound role in shaping identity, but for much of human history how they are determined has remained obscure. How does sexual orientation develop? What is it? Can it be changed?

One of the strangest features of quantum mechanics is also potentially its most useful: entanglement. By harnessing the ability for two particles to be intimately intertwined across great distances, researchers …

Search and rescue robots are able to go into places humans can’t and shouldn’t…this is the cool job of roboticist Edwin Olson who now makes autonomous shuttles. Episode filmed live …

What are the special challenges, pitfalls, opportunities and rare triumphs of seeking and synthesizing the essence of someone whose passion—quantum physics, number theory, nucleic acids, atomic species, computational design, gravitational phenomena—is so thoroughly foreign to the concerns of everyday life?

Stephen Wolfram joins Brian Greene to explore the computational basis of space, time, general relativity, quantum mechanics, and reality itself. This program is part of the Big Ideas series, supported …

As physicists attempt to answer some of science’s biggest questions about the universe, they are testing the limits of experimental and observational science itself. In this program leading physicists, astronomers, …
