The video explains quantum tunneling, using a classical analogy of a ball over a hill. It introduces the particle in a box model, highlighting the conditions for tunneling, such as finite potential energy and wave-like properties. The wave function's behavior during tunneling is discussed, along with the role of the Heisenberg uncertainty principle in determining tunneling probability. The video concludes with a formula for calculating tunneling probability.
