Page "Copenhagen interpretation" Paragraph 25

: This thought experiment highlights the implications that accepting uncertainty at the microscopic level has on macroscopic objects.

A cat is put in a sealed box, with its life or death made dependent on the state of a subatomic particle.

Thus a description of the cat during the course of the experiment — having been entangled with the state of a subatomic particle — becomes a " blur " of " living and dead cat.

" But this can't be accurate because it implies the cat is actually both dead and alive until the box is opened to check on it.

But the cat, if he survives, will only remember being alive.

Schrödinger resists " so naively accepting as valid a ' blurred model ' for representing reality.

" How can the cat be both alive and dead?
