The following questions are addressed in this chapter. They are better discussed in a group to allow a variety of opinions to emerge. The relevant section link is given after each question:
1. Why is light still a mystery to science? (QR3.1.1)
2. Is light made of waves, particles, or both? (QR3.1.2)
3. In Young’s experiment, does a photon go through both slits or just one? Give reasons. (QR3.1.3)
4. What is the main issue that Bohr’s Copenhagen dualism faces? (QR3.1.4)
5. What is meant by a “Pinocchio” theory? Is quantum mechanics one in current physics? (QR3.1.5)
6. How do scientists know that light is a wave? (QR3.2.1)
7. What is meant by a three-dimensional “Flatland”? Could our world be so? (QR3.2.2)
8. According to current physics, is a photon a perpetual-motion machine? (QR3.2.3)
