This is a supplement and continuation of the Udemy course "Quantum Physics: an overview of a weird world (Basics)". The first part furnished the basics of Quantum Physics, this part dwells deeper into other aspects. Topics addressed are the stability and solidity of matter, the Bell's inequality and Bell theorem, the Aharonov-Bohm effect, Feynman path integrals and Feynman diagrams, and the quantum Zeno effect, the 'which-way' and quantum eraser experiments, interaction free experiments and Wheeler's delayed choice experiment and quantum teleportation (an intro to quantum computing, quantum cryptography and the interpretations of quantum mechanics is coming soon). It may also be interesting for physicists who want to deepen their conceptual foundations that conventional college do not deliver.
