The Double-Slit Experiment
By shooting an electron at a wall with two slits positioned in front of a screen, physicists found that matter can exhibit the characteristics of a wave in one case and a particle in another. If the researchers measured the system while it was evolving, each electron went though one slit as a particle, but when the measurement was taken at the end, each electron went through both slits as a wave.
