Almost everything is made of particles. Particles can be atoms, molecules or ions. Particles behave differently in solids, liquids and gases. The particle model explains the differences between solids ...

The standard model of particle physics is often illustrated as a simple grid showing the 17 basic particles (shown above). But an alternative way of visualising it reveals the complex rules that ...

Matter can exist in three common states on Earth: solid, liquid and gas. This series explores how matter changes state and how we use matter in all states in our everyday lives. Excellent introductory ...

Scientists have spotted a famously elusive particle: The axion - first predicted 42 years ago as an elementary particle in extensions of the standard model of particle physics. Scientists at the Max ...
