Without dark matter and dark energy, the equations of physics don’t match what we observe in the cosmos. But what if it’s not the universe that needs extra ingredients—but the …

MIT physicist Daniel Harlow joins Brian Greene to explore black holes, holography, and the surprising connection between spacetime and algorithms that perform quantum error correction. This program is part of …

Mathematics has an uncanny ability to describe the physical world. It elegantly explains and predicts features of space, time, matter, energy and gravity. But is this magnificent scientific articulation an …

With his General Theory of Relativity, Einstein illuminated the grand expanse of the cosmos, but he was also instrumental in developing quantum mechanics for describing the microworld. In Einstein’s day, …

#YourDailyEquation with Brian Greene offers brief and breezy discussions of the most pivotal equations of the ages. Even if your math is a bit rusty, these accessible and exciting stories …

Professor Witten is a leading light of superstring theory and the only physicist to have won the vaunted Fields Medal, mathematics’ highest honor. Known for advancing a number of novel approaches in mathematics and physics, Witten opened up new vistas in 1995 when he unified five seemingly competing superstring theories into M-theory, which seeks to unify Einstein’s general theory of relativity with quantum mechanics.
