Quantum physics overturned classical ideas by showing that matter behaves very differently at the ...

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

Sorta sparked by this comment someone made to me but it's similar to what other people have told me before: I was listening to a lecture on quantum electrodynamics and it helped me conceptualize the ...

“Positronium is the simplest atom composed of equal-mass constituents, and until it self-annihilates, it behaves as a neutral ...

Physicists have finally confirmed a phenomenon that sounds like pure science fiction: waves that appear to bounce off a sudden change in time rather than a surface in space. The effect, known as a ...

Scientists are engineering electromagnetic waves to retrace their temporal paths, a breakthrough in wave physics. This 'time reversal' doesn't involve historical travel but reverses a wave's sequence, ...
