Heisenberg's Uncertainty Principle Physics Humour Bumper Sticker

Introduced first in 1927, by the German physicist Werner Heisenberg, the Heisenberg's uncertainty principle states that the more precisely the position of some particle is determined, the less precisely its momentum can be known, and vice versa. In other words, two variables that do not commute cannot be measured simultaneously—the more precisely one is known, the less precisely the other can be known. Let your wry quantum mechanics side shine with any of these gifts featuring an illustration of Heisenberg's uncertainty principle along with the following ponderous, existential geek humour caption: "How Certain Are You Of Anything In This Uncertain World?"
