Discover the bizarre behavior of quantum particles just before measurement in this animated science video. We'll unpack Schrödinger's Cat thought experiment and explain why quantum particles exist in fuzzy probabilistic states prior to observation. You'll learn why the very act of measuring a quantum system causes abrupt changes in the system. We'll also explore interpretations of quantum mechanics that attempt to explain this utterly strange phenomenon on the subatomic scale. Whether you are a physics newbie or a quantum veteran, this animated video will give you an intuitive understanding of the unbelievable uncertainty that defines the quantum world.
