Understanding the Complexity of Quantum Mechanics

AI Thread Summary
Quantum Mechanics presents challenges, particularly in understanding complex concepts like the Schrödinger equation and Fourier analysis. The discussion highlights the difficulty of grasping the derivation of equations, leading to frustration over seemingly arbitrary assumptions and rules. Despite initial ease in learning, the complexity of future topics raises concerns about the clarity and coherence of the material. The experience reflects a common sentiment among students that quantum mechanics can feel convoluted and difficult to follow. Ultimately, the conversation underscores the intricate nature of quantum mechanics and the struggle to reconcile foundational learning with advanced concepts.

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.
 
Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
