1. In terms of the scale of the Universe (the large or the small), where do the laws of Quantum Mechanics (QM) essentially apply? QM applies to every atom regardless of it is in humans, animals or inanimate objects of any shape or size. However these laws determine on what goes on in quantum level, they predict the behaviour of atoms. this have effects on the normal size world we see around us essentially describing reality. 2. Have the laws of QM been falsified to date? For the past 75 years, the QM laws have never been falsified. They agree with every experiment that’s ever happened and never proved to be wrong. 3. The appearance of sharp lines in spectra (remember emission and absorption)—through the notion of "quantum leap"—was explained by which scientist? Neils Bohr was the first scientist to explain the appearance of sharp lines through notion of quantum leap. 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? When electrons are fired through the two slits, a pattern of stripes is formed. These stripes are even present between the two slits. 6. Why did Einstein dislike the notions of Quantum Mechanics? Einstein disliked the notion of this because before the discovery of this everything was certain and was calculatable. But now at the very base of everything that is quantum level, everything is decided by chance. The notion of quantum mechanics brought the uncertainty in physics which was disliked by Einstein. 7. What are some inventions based on the ideas of QM? Lasers, transistors, integrated circuit, the entire field of electronics Microscopic switches in electronics 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. For Einstein, he expected that there would be a simpler explanation to it, unlike the explanation given by QM. There is nothing connected, it is bizarre that this happens.

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 huge increase in computing capacity. Predicting weather. Predicting natural disastors. Pulling results from billions of items of information in far less time....
