The fastest man made spacecraft are the Helios-A and Helios-B probes that set up a maximum speed record of 70,220 m/s (252,792 Km/h). Knowing than Helios-A had a mass of 370 kilograms. What was its mass when it achieved its record speed? 6. In the comedy cartoon strip Robotman, created by Jim Meddick in 1985, Robotman mentioned to his friend that you can, in fact, travel faster than the speed of light if you are going downhill. Explain briefly why Robotman’s theory does not make any sense, from a scientific point of view. B-Schrödinger’s cat The famous cat paradox first appeared in print in 1935. Einstein saw the Schrödinger’s proposal as “the prettiest way” to show that the wave representation of matter is an incomplete representation of reality. It is still discussed in quantum theory today and it has not been resolved to everyone’s satisfaction. Yet the concept behind this thought experiment is very simple. Schrödinger suggested that we should imagine a box that contains a radioactive source, a detector that records the presence of radioactive particles (like a Geiger counter), a glass bottle containing a poison such as cyanide, and a live cat. The apparatus in the box is arranged so that the detector is switched on for just long enough so that there is a fifty-fifty chance that one of the atoms in the radioactive material will decay and the detector will record a particle. If the detector does record such an event, then the glass container is crushed and the cat dies; if not, the cat lives. We have no way of knowing the outcome of this experiment until we open the box to look inside; radioactive decay occurs entirely by chance and is unpredictable except in a statistical sense. In this thought experiment, the equal probabilities for radioactive decay and no radioactive decay should produce a superposition of states. 1. Please watch the following video about Schrödinger’s cat and briefly explain, in your own words, the concept of superposition of states. https://youtu.be/OkVpMAbNOAo 2. Please answer this in your opinion. From all the quantum mechanism theories, theorems and explanations that we have seen in the lectures, which one is more closely related to the concept of superposition of states? If you are interested, you can watch this video about Schrödinger’s cat memes. There are many more memes in internet. https://youtu.be/1BENCggJGnc

A-The EPR Paradox
1. Please watch the following video about the EPR Paradox:
https://youtu.be/f72whGQ31Wg
Ans : Seen.
2. Explain briefly, in your own words, what Einstein meant by “God does not play dice”.
Ans: Einstein in 1945 expressed his opinion on quantum physics by quoting a statement he had already made famous: "God does not play dice with the universe." "God tirelessly plays dice under regulations which he has himself defined," he stated in the letter (Grenspan, 2019). This variation emphasised his claim that quantum particles must follow specific principles that do not alter at random, and that the quantum world necessitated improved particle behaviour explanations (Haug, 2019).
3. Explain briefly, in your own words, why Bell’s inequality is violated in Quantum mechanics.
Ans: A violation of the Bell inequality might be seen as proof that measurements can have numerous outcomes. Bell's theorem is a big step forward in our understanding of quantum physics' conceptual foundations. The theorem demonstrates that virtually all local theories of natural events formulated under the paradigm of realism may be evaluated with a single experimental setup.
There are comments in the video talking about nothing being able to be faster than light (superluminal speed).
This is bound to Einstein’s formula for the variation of mass m with its velocity v:
Where m is the mass at a particular speed, mo is the mass of the resting object, v the velocity at a given time, and c is the speed of light.
4. What will happen if an object travels faster than the speed of light? Please explain it briefly
Ans: According to special relativity, nothing can travel faster than the speed of light. According to the hypothesis, if something exceeds this limit, it will travel backward in time (Chang &...
