Explain:

(5) a. Why quantum mechanics is needed by describing a relevant

experimental result (not Young’s experiment).

(Please just point out the particular experimental feature or features relevant to the need of quantum mechanics and do not discuss the experimental setups.)

Expert Solution

First we should understand what is the basic difference between classical and quantum mechanics so that we can build concept ,why the need of quantum mechanics .

In classical mechanics domain we can determine the position and momentum of a particle simultaneously because we are observing the particle at large scale while in quantum mechanics we can not determine the position and momentum of a particle simultaneously that is nothing is deterministic in quantum mechanics that is why we calculate probability of finding particle.

From these points we find that probability of error in our experiment that is why quantum mechanism is important

When we take any observation through any experiment we check weather the two observations commute that is the order of two experimental observation does not change the result or they does not commute.

In a two-page paper, research three examples of technologies that use quantum mechanics. Explain, in your own words, how these applications impact society. If you or someone you know has ever had an MRI scan for a medical diagnosis, you have experienced the result of quantum physics for measuring bodily structures. Finally, provide another specific example from your own life that could be influenced by these applications.

Why does Quantum Mechanics not follow Einstein's Theory of General Relativity? If that's completely true, [we know that "The Higgs boson does not technically give other particles mass. More precisely, the particle is a quantized manifestation of a field (the Higgsfield) that generates mass through its interaction with other particles." ] will it follow the famous equation E=mc²?
