Schrödinger's Cat
Quick fact
Schrödinger created this thought experiment in 1935 as a critique of the Copenhagen interpretation, not as a literal description of reality. He intended to show that applying quantum mechanics to macroscopic objects leads to logical contradictions.
Why this is interesting
Imagine a cat in a sealed box that could be both dead and alive at the same time—until you open the box. That's the unsettling scenario Schrödinger proposed to highlight the absurdity of quantum rules applied to everyday objects.
