PROFESSOR LARRY GOPNIK, speaking as he writes on chalkboard: …X squared, so that delta X equals the square root of .077 A squared minus zero, from which we derive the square root of .077 A squared…And also, the uncertainty in P is equal to the square root of bracket P squared minus bracket P squared, which also equals the square root of H over A squared. Which lets us delta X, delta P equals the square root of .077 A squared, H over A squared, and 1.74 H bar.
Okay? The Uncertainty Principle!…It proves we can’t ever really know what’s going on.

…But even though you can’t figure anything out, YOU WILL BE RESPONSIBLE FOR IT ON THE MIDTERM!
