A Simple Illustration That Explains How The Uncertainty Principle Works

Heisenberg's definition of his uncertainty principle ("The more precisely the position is determined, the less precisely the momentum is known in this instant, and vice versa") may not be instantly clear, but here's a simple example that somehow makes it all remarkably easy to grasp. » 3/20/15 4:20pm 3/20/15 4:20pm

Why removing the uncertainty principle accidentally creates perpetual…

Werner Heisenberg's uncertainty principle tells us it's impossible to know simultaneously the location and the velocity of a subatomic particle. It's one of the main ideas that famously prompted Albert Einstein to declare God doesn't play dice with the universe. » 6/24/12 4:00pm 6/24/12 4:00pm

Quantum computers could overturn Heisenberg's uncertainty principle

The uncertainty principle is at the foundation of quantum mechanics: You can measure a particle's position or its velocity, but not both. Now it seems that quantum computer memory could let us violate this rule. » 8/03/10 7:30am 8/03/10 7:30am
