Here’s a curious question: Do certain physical events have no cause, or is there a reason behind every action? This conundrum lies at the heart of one of the strangest areas of foundational science.

Quantum mechanics represents one of the most successful scientific theories of the twentieth century, describing the behaviour of matter and energy at atomic and subatomic scales. Central to its ...

Excerpted from Quantum Strangeness: Wrestling with Bell’s Theorem and the Ultimate Nature of Reality by George Greenstein. Foreword by David Kaiser. Copyright 2019 ...

Quantum mechanics is a weird thing. It says that we can never really know all there is about reality. If we measure a particle, we can't know its exact momentum and position at the same time. If we ...

My question regards Einstein's belief that quantum theory was incomplete due to its seemingly probablistic nature. From what I gather he believed that there was some other theory, some deeper theory, ...

Quantum theory predicts the existence of so-called tripartite-entangled states, in which three quantum particles are related in a way that has no counterpart in classical physics. Theoretical ...

This video explores quantum entanglement, Bell’s inequality, the EPR paradox, nonlocality, and the debate between determinism and nondeterminism. It centers around the arguments between Bohr and ...
