Light can hit a lead halide perovskite crystal that is anything but pristine and still end up as useful electric current. That mismatch has bothered solar researchers for more than a decade. Silicon ...

In our three-dimensional space, elementary particles neatly filter into either bosons or fermions. But in lower dimensions, that distinction gets a bit murky.

Learn the key differences between centripetal and centrifugal force in this clear and engaging physics tutorial! Understand how centripetal force keeps objects moving in a circular path, while ...
