So we can do this essentially for any atom we want, we just have more and more wave functions that we're breaking it up to as we get to more and more electrons.

This extension of the photoelectric effect, in which one photon knocks one electron off the edge of an atom, could make physicists reconsider when light is a wave and when it's a particle.

As a neutrino strikes an atom, the energy of the collision warms the immediate surroundings, causing them to expand ever so slightly and trigger a minuscule shock wave of a specific shape.
