At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same time. Matter no longer behaves like solid objects moving along clear paths.

They ask us to believe, for example, that the world we experience is fundamentally divided from the subatomic realm it’s built from. Or that there is a wild proliferation of parallel universes, or ...

Extremely cold atoms have been nudged to self-magnify their quantum states so they can be imaged in unprecedented detail. This could help researchers better understand what quantum particles do in odd ...

Quantum mechanics continues to offer profound insights into the fundamental nature of matter and energy, and the use of special functions plays a critical role in obtaining exact analytical solutions ...

A groundbreaking experiment demonstrates yet again that light exists both as a wave and a particle in the quantum world—but we can’t see both at the same time. Reading time 3 minutes Albert Einstein ...

Quantum mechanics is one of the most successful theories in science — and makes much of modern life possible. Technologies ranging from computer chips to medical-imaging machines rely on the ...
