Schrödinger's Cat is thought experiment that shows something called superposition, with a box, a cat, some poison (or radiation, or bomb, or whatever, it is just supposed to kill the cat), and a object that could read a particle's spin. Erwin Schrödinger thought that if you put a cat in a box with something that could harm them, and you can't see inside the box, the cat is both dead and alive all at the same time.
The /g/ sound is the the voiced cognate of the unvoiced /k/, and the /d/ sound is the voiced cognate of the unvoiced /t/, thus, articulator placement during production cat is identical to the production of the word god. God backwards may be dog, but God unvoiced is cat.
