1. In terms of the scale of the Universe (the large or the small), where do the laws of Quantum Mechanics (QM) essentially apply? Any atom, whether in humans, animals, or inanimate objects of any shape or size, is subject to QM. These rules, on the other hand, decide what happens at the quantum level and predict atom behavior. This has implications for the normal-sized world we see around us, which is simply representing reality. 2. Have the laws of QM been falsified to date? The QM laws have never been falsified in the last 75 years. They agree with any experiment that has ever taken place and have never been proven incorrect. 3. The appearance of sharp lines in spectra (remember emission and absorption)—through the notion of "quantum leap"—was explained by which scientist? Niels Bohr was the first scientist to use the concept of quantum leap to describe the appearance of sharp lines. 4. In a quantum leap, when one electron "moves" from one orbit to another, does it travel in the space between orbits? No, it does not. It just directly jumps from one orbit to another. 5. When electrons (tiny particles) are fired through a double-slit, what sort of pattern emerges? A pattern of stripes is created as electrons are shot through the two slits. Even between the two slits, these stripes can be seen. 6. Why did Einstein dislike the notions of Quantum Mechanics? Einstein despised the concept that it was definite and calculable before it was discovered. But, at the most basic level, the quantum level, everything is determined by chance. The principle of quantum mechanics introduced confusion into physics, which Einstein hated. 7. What are some inventions based on the ideas of QM? Electronics as a whole, including lasers, transistors, and integrated circuits Electronic switches that are microscopic 8. How did Bohr reply to Einstein's famous phrase, "God does not play dice?" “stop telling god, what to do”. 9. What is the craziest prediction from QM and why did Einstein consider it spooky? Entanglement. Unlike the explanation given by QM, Einstein anticipated a simpler explanation. There is no connection; strangely, this occurs.

10. Clauser's and Aspect's experiment (based on John Bell's work), supported which physicist, Einstein or Bohr? It supported Bohr’s ideas. 11. In teleportation, what happens to the original thing (particle or person) that has to be teleported? The original thing is destroyed. 12. What are some practical uses of a Quantum computer, if we could build one? A significant increase in processing power. Weather forecasting. Natural disasters can be expected. Having results from billions of pieces of data in a fraction of the time....
