A more in depth explanation found on Wikipedia: Schrödinger's cat: a cat, a flask of poison, and a radioactive source are placed in a sealed box. If an internal monitor detects radioactivity (i.e. a single atom decaying), the flask is shattered, releasing the poison that kills the cat. The Copenhagen interpretation of quantum mechanics implies that after a while, the cat is simultaneously alive and dead. Yet, when one looks in the box, one sees the cat either aliveor dead, not both alive and dead. This poses the question of when exactly quantum superposition ends and reality collapses into one possibility or the other.
To truly understand Schrödinger's paradox, some understanding of quantum mechanics is needed. That's another post for another blog. ;)
For this blog, I present, Schrödinger's rice! :)
