The Uncertainty Principle
According to the great taco philosopher, Heisenbergtacos, "It's not the size of the taco that matters, it's the uncertainty of its contents."
Δx > 0Δp > 0Δx * Δp = hh = taco mass * taco velocity
Where Δx is the uncertainty in taco position, Δp is the uncertainty in taco momentum, h is the taco uncertainty constant, and taco mass and velocity are variables that can be adjusted to achieve maximum uncertainty.
Apply this principle to your life and you'll find that the more you try to pin down the exact location of your taco, the more it will slip through your fingers like sand in the hourglass of existence.
Or, as the great taco sage once said, "If you want to find the perfect taco, you must be willing to be uncertain about everything else." Learn more about the taco uncertainty principle.
