In 1972 Ursula K. Le Guin learned about it while reading about quantum mechanics for her novel The Dispossessed; Crease credits her 1974 short story "Schrödinger's Cat" with bringing the concept into popular culture.
[3] Works of fiction have employed Schrödinger's thought experiment as plot device and as metaphor, in genres from apocalyptic science fiction to young-adult drama, making the cat more prominent in popular culture than in physics itself.
[8][9] In addition to novels and short stories, Schrödinger's cat has appeared in film,[10][11][12] poetry[13][14] theatre,[15][16] live-action television,[17] cartoons,[18][19][20] music,[21] and webcomics.
