Is the electron a wave or a particle? Are the orbits of electrons in atoms similar to planetary orbits? What is the nature of light? Such were the questions that physicists were struggling with in the ...

How a group of free-thinking physicists in the 1970s helped shape quantum physics. In seeing quantum entanglement as central to physics, The Fundamental Fysiks Group were decades ahead of their time.

In the 1920s, when quantum mechanics was young, physicists Jane Dewey and Laura Chalk performed some of the first experimental tests of the theory, based on a phenomenon called the Stark effect. Later ...
