Ebook: Through two doors at once: the elegant experiment that captures the enigma of our quantum reality

Many of science's greatest minds have grappled with the simple yet elusive "double-slit" experiment that Thomas Young devised in the early 1800s to show that light behaves like a wave. Decade after decade, hypothesis after hypothesis, scientists have returned to this experiment to help them answer deeper and deeper questions about the fabric of the universe. Ananthaswamy travels around the world and through history, to examine quantum mechanics from the perspective of this experiment and its variations. -- adapted from jacket;Prologue.
