particle tunnels through a hill

An example of a metaphor adopted into scientific nomenclature

"Quantum tunneling was initially conceptualised as a penetration of, or leaking through, a barrier or a hill. A particle with energy lower than the energy it takes to overcome an obstacle, a potential hill[,] can occasionally 'tunnel' through it. It is the effect of a particle tunneling through an obstacle [which would be] forbidden in classical mechanics."
