Irrotational solutions to Euler's equation for a compressible fluid
This talk is about the patterns of flow in a fluid such as the air if it had no viscosity. It is illustrated with animations and movies, and should be accessible to those without prior knowledge. We show that a compressible inviscid fluid supports structures which are similar to smoke rings, but are irrotational. They obey the same equations of motion and diffraction as natural particles, which is illustrated in movies of an experimental analogue in two dimensions, due to Couder, which show tunnelling, double-slit diffraction, and quantised energy levels. Some of the structures are chiral. Opposite chiralities attract and like chiralities repel with a force which obeys Maxwell's equations, whose strength is characterised by a fine structure constant less than approximately 1/45.

UKRI Deadlines
Due to the implementation of a new UKRI funding system (TFS) there will be a fixed quarterly deadlines for some grants which would previously have been on open calls, this is to allow necessary system amendments and updates.
The first deadline after implementation will be 28th September 2023 and applies to those calls listed below:
EPSRC Post Doctoral Fellowship
