Quantum MechanicsQuantum mechanics? Just hearing the name, we get sick. It seems to be something complicated (and is), but here I will try to explain this theory in simple terms. However, this does not mean that you will go to understand quantum mechanics. As Niels Bohr said, “who says he understands quantum mechanics, you have not understood it.” Does it look like something strange, doesn’t it? Yes so. Quantum mechanics challenges our common sense.
