Can you explain the essence of quantum mechanics in three sentences?

Quantum mechanics is the study of the tiniest components of matter and energy. The components of matter are the tiny bits inside the atom: protons, neutrons, electrons, etc. The components of energy are, in the case of light, photons. Other types of energy have other components. These components follow laws different to those of everyday …

What is the difference between theoretical quantum physics and experimental quantum physics?

Short answer: Theoretical physics is one of two branches of physics: theoretical and experimental. Like other types of physics, quantum physics has both a theoretical physics branch and an experimental physics branch. Explanation: Experimental physicists do experiments to find out how accurately physics theories describe the real world. For example, they shoot atoms and bits …

What does “measurement” mean in quantum mechanics?

In quantum mechanics, when physicists measure a property of a quantum particle, like a photon, they are really saying that they detect one of its properties. The key to understanding why “measurement” is of such consequence in the quantum world is understanding that detection creates a fundamental change in a particle’s condition. For example, let’s …

How can we tell when descriptions of quantum mechanics are woo-woo and not scientific?

[This article is under construction.] Currently, there are over 20 theoretical interpretations of quantum physics. They mostly SOUND like woo. For example, the Many Worlds Interpretation proposes that innumerable universes are created by quantum events. The de Broglie-Bohmian Interpretation proposes that every event is connected with every other event in the universe, thus explaining the …
