Here's a nice surprise: quantum physics is less complicated than we thought. An international team of researchers at the National University of Singapore has proved that two peculiar features of the quantum world previously considered distinct are actually different manifestations of the same thing. The researchers found that Wave-Particle Duality is simply the Quantum Uncertainty Principle in disguise, reducing two mysteries to one. Wave-Particle Duality is the idea that a quantum object can behave like a wave and a particle at the same time. The Quantum Uncertainty Principle is the idea that it's impossible to know the exact speed and exact position of a particle at the same time. These concepts have been known to physicists since the early 1900s. This discovery deepens our understanding of quantum physics and could prompt ideas for new applications of wave-particle duality.
