How can maths help to understand the Southern Ocean, a vital component of the Earth's climate system?

This year's Abel Prize goes to Luis A. Caffarelli for a body of work on the maths of change.

How does your phone know what the weather's going to be like?

Where do the magnetic fields of planets and stars come from?

It's a good question with a fascinating answer.

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

An insightful look at the climate models that predict our future.

The mathematical problem with turbulence.

Few things in nature are as dramatic, and potentially dangerous, as ocean waves. The impact they have on our daily lives extends from shipping to the role they play in driving the global climate. From a theoretical viewpoint water waves pose rich challenges: solutions to the equations that describe fluid motion are elusive, and whether they even exist in the most general case is one of the hardest unanswered questions in mathematics.

Andy Green, Royal Air force pilot and Oxford maths graduate, is gearing up to break his own land speed record in Bloodhound SSC, a supersonic car designed to reach speeds of up to 1000mph. He tells Plus about the challenges — and the maths — behind this engineering adventure.

In 1997 Andy Green was the first to break the sound barrier in his car Thrust SSC, which reached speeds of over 760mph. Now he and his team want to push things even further with a car called Bloodhound, designed to reach the dizzy heights of 1,000mph, about 1.3 times the speed of sound. Ben Evans explains how maths is used to build this car.
