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

During the early 1900’s, [Einstein] was virtually at war with quantum theory. Its unofficial leader, [Niels Bohr], was constantly rebutting Einstein’s elaborate thought experiments aimed at shooting ...

The philosopher in the street, who has not suffered a course in quantum mechanics, is quite unimpressed by the [Einstein-Podolsky-Rosen] correlations. He can point to many examples of similar ...

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, ...

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 ...

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, ...

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.

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 ...
