Digital revolution: how AI can help (not hinder) physics

The use of artificial intelligence is already commonplace in physics, but could physics also help AI? Tara Shears, who is a particle physicist at the University of Liverpool, examines the relationship between the two fields following a survey and report by the Institute of Physics. Also this month, there’s the third part of Keith Cooper’s exploration of the battle between dark matter and modified gravity to explain the composition of the cosmos, while Emanual Wallace, aka Big Manny, explains how he’s become the new face of science communication. Finally, Robert P Crease brings you your favourite physics metaphors.
