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

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 ...

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.

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, ...

Not all revolutions start big. In the case of quantum mechanics, a quiet one began in 1964, when physicist John Bell published an equation. This equation, in the form of a mathematical inequality, ...

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...

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 ...

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 ...
