In this highly entertaining performance combining math with magic, Arthur Benjamin—aka, the the “Mathemagician”—displays amazing feats of mental mathematical gymnastics and explains the secrets behind his lightning-fast math skills. How does the Mathemagician best an electronic calculator?

In what many call a “golden age of cosmology”, astronomers can now observe the universe with unprecedented precision, resulting in spectacular progress in the search for the origin of the universe. Yet, for all the impressive progress, fundamental questions remain. What is the mysterious “dark energy” driving space to rapidly expand?

We’ve assembled an all-star group of ecologists, naturalists, and creative thinkers for an urgent but hopeful conversation about the environmental pressures bearing down on Earth’s rich spectrum of species.

In his research, U.K. Astronomer Royal Martin Rees has tackled topics as varied as the Big Bang, quasars, and more far-out ideas like the search for dark matter and the …

Albert Einstein spent his last thirty years unsuccessfully searching for a ‘unified theory’ — a single master principle to describe everything in the universe, from tiny subatomic particles to immense clusters of galaxies. In the decades since, generations of researchers have continued working toward Einstein’s dream.

After a storied career with 5 spaceflights (including three trips to fix the Hubble Space Telescope), NASA astronaut John Grunsfeld now helms the space agency’s scientific missions. He helps shepherd …

Does your dog really think and feel like a human? Do our closest primate relatives have brains and emotions similar to ours? What about the storied intelligence of dolphins and singing humpback whales? And do other species hold surprises for us if we’re willing to look closely?

Music students download the technique of their favorite pianist or singer directly into their brains. Medical students download the skills of a seasoned surgeon or diagnostician. And each one of us routinely uploads our thoughts and memories to the digital cloud.
