24: Quantum Weirdness
In this chapter, we will delve deeper into the strangeness of quantum mechanics. In particular, we will explore quantum phenomena that don’t have a classical counterpart, starting from perhaps the most simple but also one of the most revealing: the double-slit experiment.

- 24.3: Tunneling
- Tunneling is a phenomenon where a particle may cross a barrier even if it does not have sufficient kinetic energy to overcome the potential of the barrier itself. In this situation, the particle is said to “tunnel through” the barrier following a purely quantum mechanical phenomenon (figure 25.3.1).
