This disturbance is called back-action, and it is one of the hallmarks of quantum mechanics, which governs the actions of the very small. It arises from the supposition that before a measurement is ...
Quantum particles are not really just particles…they are also waves. The word uncertainty is used a lot in quantum mechanics. One school of thought is that this means there's something out there in ...
The word uncertainty is used a lot in quantum mechanics. One school of thought is that this means there’s something out there in the world that we are uncertain about. But most physicists believe ...
