Professor Aephraim Steinberg, winner of Physics World's Breakthrough of the Year in 2011, is an experimentalist who thinks deeply about foundations. For 30 years he's measured aspects of physics others wouldn't touch: Bohmian trajectories, Heisenberg's disturbance bound (he showed it was wrong), even where the photon is inside the double slit. His lab measured negative time, and it keeps reappearing across different experiments.
