Quantum mechanics was devised to fill in for the failures of newtonian mechanics. It created a model for explaining our strange world at an atomic scale. However, quantum tunnelling is not the same. Quantum tunnelling is a unique and especially tough part of quantum physics since it has no newtonian counter-part i.e. it has no “normal” analogy. Physicists have been baffled with quantum tunnelling since the late 1920s. It goes against what we think physics tells us yet explains important things like the alpha decay of atomic nuclei, tunnelling diodes, scanning tunnelling microscopes and superconducting qubits for quantum computing.

I do not like it, and I am sorry I ever had anything to do with it. -Erwin Schrödinger
The quantum model upset countless physicists. Wave-particle duality was the beginning of their sad endeavour and the quantum model built itself on top of it. Its relation with uncertainty and its divergence from classical mechanics was what caused the quote above. Erwin Schrödinger turned to biology after finding the laws of quantum mechanics philosophically disturbing.
I will try my hardest to make this not philosophically disturbing.
If you think you understand quantum mechanics, you don’t understand quantum mechanics.- Richard P. Feynman
The quantum field is one that has great scope and can propel us into a future of faster computing, understanding new sub-particles and perhaps even of disproving the idea that nothing can travel faster than light.
Although many places boast the ability to teach the entirety of quantum physics within days or minutes, it is important to understand that quantum physics is not a single faceted subject. It is like saying “All of Newtonian mechanics can be taught in a day.” …
