I've heard of it but don't actually know what it is. Inform me flood.

Interestingly, he made that thought experiment in order to criticize the Copenhagen Interpretation of Quantum Mechanics. He himself of course believed in the superposition notion, as his wave equation made its existence a logical certainty. He didn't like how Hiesenburg and Bohr where interpretating the data, implying that direct observation is what broke the wave-function and reduced the state from superposition to observed position. The book is still out on which interpretation is accurate, or in this case best describes the analytical method by which we determine quantum states. The only thing they're pretty sure of in this scenario is that cat scale objects don't exist in a superposition, and that the math involved is solid and self-consistent.
