A December health crisis, escalating into a week-long intensive care unit stay, prompted Karmela Padavic-Callaghan to seek answers not in medical charts, but in the principles of quantum physics. Her book, Entangled States: A life according to quantum physics, argues that viewing objective principles subjectively can be a perspective reinforced by grappling with the causes behind a near-fatal illness.
