Andrew Michael Soward (born October 20, 1943 – died July 20, 2025) was a smart British scientist. He studied how liquids and gases move, which is called fluid dynamics. He was a professor at the University of Exeter.

Education and Early Life
Andrew Soward went to Queens' College, Cambridge for his university studies. He worked hard and earned his PhD degree in 1969. His main teacher and guide during his PhD was a famous scientist named Keith Moffatt.
What Andrew Soward Studied
Andrew Soward was well-known for his work in a field called magnetohydrodynamics (MHD). This is a fancy name for studying how electrically charged fluids, like melted metals or gases in space, move when there are magnetic fields around. He was especially interested in something called dynamo theory.
Understanding Dynamos
Imagine how the Earth creates its own magnetic field. It's like a giant natural generator, or "dynamo." Soward studied how these dynamos work. He used special math tools, called asymptotic analysis, to solve tricky problems in this area.
He even showed examples of "fast dynamos." For a long time, some scientists thought these types of dynamos couldn't exist. But Andrew Soward proved them wrong!
How Fluids Move and Change
Soward also looked at how fluids behave in different situations. He studied stability theory, which helps us understand if a fluid flow will stay smooth or become turbulent and chaotic.
He discovered new ways that fluids move when they are heated and spinning, like boiling water in a pot that's also rotating. This is called convection.
Working with Magnetic Fields
Andrew Soward worked with another scientist, Steven Childress, to create a model of how magnetic fields are made in a rapidly spinning layer of fluid. He also showed that sometimes, magnetic fields are created more easily if the fluid flow is wobbly or "oscillating" instead of steady.
He also teamed up with Eric Priest to explain how magnetic field lines can break and reconnect. This process is super important for understanding things like solar flares on the Sun.
Solving Tricky Math Problems
Soward was very good at solving complex math problems. He found the first complete solution to a problem called the Stefan problem for a cylindrical shape. This problem helps us understand how things freeze or melt.
With another scientist, C.A. Jones, he also solved the Taylor problem for a sphere. This problem describes how fluids move between two spinning spheres.
Awards and Recognition
Because of his important discoveries and contributions to science, Andrew Soward was given a big honor. He was elected a Fellow of the Royal Society (FRS) in 1991. This is a very respected award for scientists in the United Kingdom.
