The development of classical electromagnetism and quantum electrodynamics are highpoints of nineteenth and twentieth century physics, respectively. Recent, remarkable discoveries, involving neutron stars and black holes, are taking electrodynamics into unfamiliar and “extremeâ€Â territory, requiring new theoretical approaches. Examples include 100 GT (10^15 Gauss) magnetic fields surrounding neutron stars (and ...
I will discuss how vertebrate skin colours and skin appendages (scales, feathers, hairs, ...) are patterned through Turing and mechanical instabilities. First, I will show that Reaction-diffusion (RD) models are particularly effective for understanding skin colour patterning at the macroscopic scale, without the need to parametrise the profusion of variables ...
In 2007, astronomers discovered a new mysterious cosmic phenomenon: Fast Radio Bursts. These events consist of short, intense blasts of radio waves arriving from far outside our Milky Way galaxy. Their origin is unknown, however Fast Radio Bursts appear ubiquitous in our Universe, with roughly 1000 arriving every day over ...
