Quantum mechanics describes a particle with a wavefunction ψ, but experiments record definite clicks. The Born rule is the bridge: the probability of finding the particle is the squared magnitude...

Four coloured streams of force spiralling inward and converging on one brilliant knot of light

Is There a Theory of Everything, and What Would...

Physics has a tested theory for three forces and a separate one for gravity, but no accepted theory joining them. The graviton, gravity’s hypothetical carrier particle, has never been seen....

Blank glowing gem blocks arranged in the shape of the periodic table, with a glowing atom in front

Why Does the Periodic Table Have the Shape It D...

The periodic table is not a random grid. Its rows hold 2, 8, 8, 18, 18, 32 and 32 elements because electrons fill shells and subshells, and the Pauli exclusion...

Fast shallow water in a channel rising into a deep, slow, foaming hydraulic jump

Kármán Vortex Streets and Hydraulic Jumps: Why ...

Put a cylinder in a steady flow and it sheds a staggered trail of whirlpools called a Kármán vortex street. Let a fast, shallow stream slow down and it leaps...

The James Webb Space Telescope at L2, its sunshield between the distant Sun, Earth and Moon and its golden mirror

What Are Lagrange Points, and Why Does JWST Sit...

Lagrange points are five spots where a small object can keep pace with two big ones, like a spacecraft riding along with the Sun and Earth. We work out where...

Two glowing electron trails meeting at bright vertices linked by a wavy pink photon in starry space

A Feynman diagram is not a photo of particles bouncing around. Each little drawing stands for one term in a calculation of how likely a process is. Here is how...
