Hi Learned Members,
I am not a regular physics student but a curious one. I have read some books written for laymen by physicsts - (like In search of Schrodinger's cat). I do not understand few basic things below. Maybe I am not even framing the questions correctly. Please excuse me if so.
1. Was quantum physics invented simply because of the assumed failure of our ability to view particles like electron (because the photon knocks-off the electron)?
2. What is the practical use of uncertainity principle? It simply seems to justify uncertainity. Was this ever used/proved by experiment? Or is this simply a rule arrived because we do not have instruments to track an electron?
3. Are we not simply inventing theories just because we do not have instruments to observe the behaviour of sub-atomic particles like electrons?
4. And, because of the above, every other person on Earth tries to justify everything - (spoon bending, time travel, multiple worlds mentioned in some religions, sci-fi movies and so on) and point to Quantum Theory as proof. What is really possible according to Quantum Physics?
5. Has any of the theoratical surmises/predictions(Quantum Physics) been proved conclusively by experiments? If so, could you give the names of the experiments?
I do not mean to offend anyone. I understand fully that I am half-baked. Could someone please enlighten me?
