Heisenberg's uncertainty principle, according to which nature is inherently indeterministic, implies an open future (and, for that matter, an open past).
The best clocks now scan a one-hertz-wide sweet spot to find its exact center, plus or minus one millihertz, in every single measurement—despite the Heisenberg limits.
Would you prefer a simpler application of Heisenberg's uncertainty principle, in which I could either know where you are or whether I like you, but not both.
He is known for many breakthrough discoveries over the course of his career, and the Heisenberg Uncertainty principle is one of them, which he first published in 1927.
Among his many revolutionary ideas, the most significant is undoubtedly the Heisenberg Uncertainty Principle, a concept that challenged traditional physics and created a new paradigm in quantum theory.
That although it's a particle, because of the Heisenberg uncertainty principle, we can never tell exactly at a given moment where the particle is and what its momentum is.
This is a direct consequence of the Heisenberg Uncertainty Principle, which says that the better you know where a quantum particle is, the less you know about its velocity, and vice versa.
That's 14 hours away. For the next 840 minutes, I'm effectively one of Heisenberg's particles; I know where I am or I know how fast I'm going, but I can't know both.
