Niels Bohr's Nobel Lecture on December 11, 1922, titled The Structure of the Atom, is one of the most significant contributions to our understanding of atomic structure and quantum mechanics. This ...

Double-slit experiments illustrate the quintessential proof for wave–particle complementarity. If information is missing about which slit the particle has traversed, the particle, behaving as a wave, ...

A groundbreaking experiment demonstrates yet again that light exists both as a wave and a particle in the quantum world—but we can’t see both at the same time. Reading time 3 minutes Albert Einstein ...

Quantum studies took a massive leap in the middle of the 20th century, with a host of European scientists successfully attempting to unlock the mysteries of the atom. In these endeavours, Danish ...

In a quiet lab at MIT, a group of physicists may have just resolved one of the most iconic debates in the history of science. Using state-of-the-art tools and techniques that Albert Einstein and Niels ...

Quantum mechanics dictates sensitivity limits in the measurements of displacement, velocity and acceleration. A recent experiment at the Niels Bohr Institute probes these limits, analyzing how quantum ...

A new experiment captures a single parcel of light morphing between wave and particle. Published in the April Physical Review A, the experiment dissects a light pulse associated with a single photon ...

It’s not quite a do-it-yourself particle accelerator for the home, but as part of an outreach project at the Niels Bohr Institute, Physics postdoc Sascha Hehlhase has assembled a stunning model of ...
