Aideen’s story has sparked an overwhelming response, showing the real impact that pavement parking has on people’s daily lives across the UK.
This is why we are campaigning to end pavement parking.

How much information can we gain by pushing numerical relativity to its limit by simulating black hole scattering encounters? My latest paper (below) explores these extreme regions of the black-hole scattering parameter space using simulations generated using the Spectral Einstein Code (SpEC).
Black-hole scattering with numerical relativity: Self-force extraction and post-Minkowskian validation
The asymptotic nature of unbound binary-black-hole encounters provides a clean method for comparing different approaches for modeling the two-body problem in general relativity. In this work, we use n...

A big blanket VAT cut? It's a bad idea. Better to give smarter, more targetted supports for cafes and restaurants.
We've set out a way to give more to small businesses while spending about a third of what the government are planning.
