Quantum Legacies: Dispatches from an Uncertain World

A series of engaging essays that explore iconic moments of discovery and debate in physicists’ ongoing quest to understand the quantum world.

The ideas at the root of quantum theory remain stubbornly, famously bizarre: a solid world reduced to puffs of probability; particles that tunnel through walls; cats suspended in zombielike states, neither alive nor dead; and twinned particles that share entangled fates. For more than a century, physicists have grappled with these conceptual uncertain...
