The theory of Quantum Chromodynamics (QCD) underpins our understanding of the strong interaction, governing how quarks and gluons interact to form hadrons. One of the most promising nonperturbative ...

Certain quantities appear as integer multiples of fundamental and indivisible elements. This quantization of physical quantities at the heart of our description of nature, made its way through the ...

Quantum mechanics is the field of physics governing the behavior of things on atomic scales, where things work very differently from our everyday world. One of the most direct manifestations of ...

The speed of light is a fundamental constant, approximately 299,792,458 meters per second. It's the same for all observers and hasn't changed measurably over billions of years. Nothing can travel ...

Physicists have proposed a way to braid three beams of light by guiding the beams along swirling, vortex-shaped defects in the optical medium through which the beams travel. The braided light would ...

Later work by others built on this, showing that these energy levels are a fundamental part of how the universe works at the smallest scales. It was a huge step in moving away from older ideas about ...
