One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the ...

For the first time, physicists have watched a beam of positronium, a short‑lived atom made of an electron and its antimatter ...

Far from being a solely quantum mechanical phenomenon, interference occurs with all kinds of waves, including water waves and sound waves. Interference is the process in which two or more waves of the ...

Gravitational waves are distortions or “ripples” in the curvature of space-time. Think of the waves on the surface of a pond created by throwing a rock into it. Far away from their source, the math ...
