A new model of the formation of the Moon's crust finally explains the diversity and range of ages of rocks found on the lunar surface.

How does a smooth flow suddenly become turbulent? The Reynolds number helps understand the transition.

How does water, or indeed any fluid, move? The Euler equations let us look beneath the surface and mark the beginning of modern fluid dynamics.

The mathematical equations governing fluid flow may have no known solutions, but maths still has the answers!

New research shows that ventilation is crucial and that masks are effective.

How do green algae manage a perfect breaststroke even though they haven't got a brain? Enter the maths of synchronisation.

How far can virus-carrying droplets fly in different environments — from buses to supermarkets? Maths can provide some answers.

How do green algae manage a perfect breaststroke even though they haven't got a brain? The maths of synchronisation explains and even sheds light on human physiology and evolution.

We can't let penguin awareness day pass without a look at some penguin maths.
