An old puzzle in particle physics has been solved: How can quantum field theories be best formulated on a lattice to ...

For decades, physicists have faced one of science’s greatest puzzles: merging quantum mechanics, which describes tiny particles, with general relativity, which explains the universe’s vast structures.

A hundred years ago, quantum mechanics was a radical theory that baffled even the brightest minds. Today, it's the backbone of technologies that shape ...

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...
