By 1926 he published his work, providing a theoretical basis for the atomic model that Niels Bohr had proposed based on laboratory evidence. The equation at the heart of his publication became ...

“Here, we have reconstructed many of the properties of other high-dimensional systems, but within an atomic-scale object – a nuclear spin. It is very exciting, and quite plausible, to imagine a ...

Devised in 1935 by the Austrian physicist Erwin Schrödinger, this thought experiment was designed to shine a spotlight on the difficulty with interpreting quantum theory. Quantum theory is very ...

"Schrödinger's cat" was designed to highlight the physicist's concerns with one interpretation of quantum mechanics—the then relatively new theory that explains how matter behaves at the atomic ...
