The wave characteristics of a particle are mathematically described by a quantity called the wave function. The square of the modulus (absolute value) of the wave function at a given position represents the probability of finding the particle at that point. 1 Quantum mechanics is inherently probabilistic. It is only when an observation is made that the wave function collapses. This feature is most apparent in the double-slit experiment which was talked about in the previous post ( https://phys-talk.blogspot.com/2020/09/the-problem-with-quantum-mechanics.html ). The wave-like nature of particles paves the way for an interesting phenomenon known as quantum tunnelling. Going through walls Quantum tunnelling is the phenomenon of particles passing through ‘seemingly impassable force barriers.’ 2 Consider a ball rolling up a hill
