While quantum mechanics explains the small-scale, low-energy behavior of electrons, relativity becomes important when those same electrons move fast enough for strange effects like spin-orbit coupling ...

"God does not play dice." This famous remark by Albert Einstein critiqued the probabilistic nature of quantum mechanics.

Researchers use electron ptychography to capture atomic vibrations in twisted 2D materials with record-breaking precision.

One of the biggest challenges in modern physics is uniting quantum mechanics and general relativity. A new experiment may ...
