He arrived onstage without a violin — neither his 1714 Soil Stradivarius nor his Guarneri del Gesu 1743 Sauret, which he has played on concert stages around the world — and still gave a command ...

For decades, physicists have been trying to combine quantum physics and general relativity into a single, unified theory. One of the leading contenders is string theory, an elegant vision in which ...

What is the stuff in the universe made of? Our high-school physics tells us atoms, with 90 natural elements building the world around us. But what are these atoms made of? Over the last century, we've ...
