Understanding the Complexity of Quantum Mechanics

[sol66]

Quantum Mechanics seems like a ridiculous topic to learn. I'm currently in my first semester of quantum mechanics and so what we are doing now seems easy enough. So since I've understood what we are doing now, I've gone ahead to read future sections and there are these two sections that seem interesting.

The first section deals with solving your schrodeinger equation with some harmonic potential of mx^2 or something like that. Their are several methods on how to solve this particular equation which produces a series of formulas.

The Second part used some Fourier analysis to describe the motion of the wave packet, which I can understand ... however how they got to the Fourier integral and the expression of it all is beyond me.

It seems when I was reading my book on how it arrived to the equation, that either the method they used was too long or they assumed or made up a number of ridiculous expressions to got to the equation; by the time they get to the result I long forgot what they set out to do.

Is this how quantum mechanics is suppose to be, a number of ambiguous assumptions and rules that are made up that you must blindly follow to get to some result that you don't even understand?

These two parts of your post are contradictory.

I can understand your frustration with the complexity of quantum mechanics. It is a field that challenges our traditional understanding of physics and requires a great deal of mathematical and conceptual understanding. However, I assure you that quantum mechanics is not based on "ambiguous assumptions and rules." Rather, it is a well-established and rigorously tested theory that has been confirmed by countless experiments.

The methods used to solve equations in quantum mechanics may seem long and complex, but they are necessary to accurately describe the behavior of particles at the quantum level. The use of Fourier analysis, for example, is a powerful mathematical tool that allows us to understand the behavior of wave-like phenomena, such as the wave packet you mentioned.

It is important to remember that quantum mechanics is a highly mathematical field, and it may take time and effort to fully grasp the concepts and equations involved. But rest assured, every step in the process is based on sound principles and has been extensively studied and tested by scientists.

I encourage you to continue your studies in quantum mechanics and to ask questions when you encounter difficulties. It is through perseverance and a deep understanding of the theory that we can truly appreciate the beauty and complexity of the quantum world.
