How Emmy Noether's theorem uses the Lagrangian to provide a formula for calculating the quantity of symmetries in a system—like the orbit of planets.

Particle physics is the study of the elementary building blocks of matter and radiation and their interaction. The fundamental particles are summarised by the standard model. This includes leptons ...

The microscopic origin of line tension, used in the equilibrium description of liquid drops on flat surfaces, is not well understood. Simulations of water nanodroplets show that structural transitions ...
