Invention and innovation are the mark of robotics engineer Dennis Hong’s lab. Watch as he demonstrates some of the remarkable robots that his team has built. The robots walk on …

For this year’s inaugural address, “The Future of Big Science,” Nobel laureate and physicist Steven Weinberg considers the future of fundamental physics, especially as funding for basic research is reduced. Weinberg will explore physics’ small origins, starting with the discovery of the atomic nucleus 100 years ago by a single scientist.

Are quantum computers the game-changer they’re described to be, or is the promise of exponential speedup overblown? Join pioneer Seth Lloyd and Brian Greene as they discuss how the fundamental …

The inflationary theory of cosmology, an enduring theory about our universe and how it was formed, explains that just after the Big Bang, the universe went through a period of rapid expansion. This theory has been critical to understanding what’s going on in the cosmos today.

A universe that continually expands has long been the dominant cosmological framework. But a universe that undergoes cycles of expansion and contraction, perhaps for all time, has recently been analyzed …

Nate Ball’s appetite for invention began with hovercrafts and Tesla coils and led to building his revolutionary ascender that uses a reliable motor to raise rescuers by a rope. These …
