The Potential Barrier, case: E ≤ V_o - Tunneling

With rigorous calculations, we finally see the fruits of our work. With irrefutable evidence, we explain conclusive with a non-zero probability from the transmission coefficient that quantum mechanical objects can tunnel through classically impenetrable barriers, very unlike classical mechanics.
