Physics World October 2016

From weapons to white dwarfs: how military labs are opening up the world

The cover story this month reveals the inside story of how military labs are opening up their research facilities to the world. The issue also looks at how breakthroughs in physics really occur – is it flashes of insight or just long, hard graft? – and examines why we could finally find discrepancies in the “equivalence principle” that inertial and gravitational mass are the same. Don’t miss either the ding-dong over China’s plans to build a new collider, our interview with Nithaya Chetty on transforming South African astronomy, or Robert P Crease’s Critical Point column on the danger of “unknown unknowns”.
