navierstokes equations
For the first time, scientists solve the equations to understand how flash rips are formed.

In issue 29 of Plus, we heard how a simple mathematical equation became the subject of a debate in the UK parliament. Chris Budd and Chris Sangwin continue the story of the mighty quadratic equation.

Can researchers solve the mathematics of turbulence at the smallest scale?

One million dollars is waiting to be won by anyone who can solve one of the grand mathematical challenges of the 21st century. In the second of two articles, Chris Budd looks at the wellposedness of the NavierStokes equations.

Read about what it is like to work at the Meteorological Office in this interview with Helen Hewson. There's also a contact point for careers information.

Have you ever been in an aeroplane on a smooth flight when suddenly the plane bumps up and down for a short time as it goes through turbulent air? The study of turbulence is used to understand a range of phenomena from the simple squirting of a jet of water to the activity of the sun.
