Physicist Yakir Aharonov argues that the standard story of quantum mechanics is wrong, proposing a time-symmetric “two-state vector” view in which reality is defined by wavefunctions from both past and future. He explains weak measurements (information without collapse), nonlocal dynamics behind interference, and phenomena like the “quantum Cheshire Cat.” Aharonov recounts the birth of the Aharonov–Bohm effect, why gauge potentials mislead about locality, and how pre and post-selection restore causal insight without determinism. He shares memories of Bohm, Heisenberg, and Feynman, touches on gravitational and non-Abelian AB analogs, and lays out why a clear narrative—not just math—is essential to understanding quantum theory.
