Should I take Quantum Mechanics?

Click For Summary

Discussion Overview

The discussion revolves around whether a second-year undergraduate student in Nanotechnology should enroll in a third-year Quantum Mechanics course, considering their mathematical background and prior physics coursework. Participants explore the prerequisites and implications of taking the course, including the necessary mathematical skills and the relevance of Quantum Mechanics to the field of nanotechnology.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant expresses concern about their mathematical background, having only completed first-year mathematics and lacking classical mechanics, questioning if this would hinder their performance in Quantum Mechanics.
  • Another participant emphasizes the importance of understanding angular momentum, central forces, and Maxwell's equations for the course, suggesting that knowledge of vector calculus, linear algebra, and matrix algebra is also crucial.
  • Some participants propose that Quantum Mechanics may be essential for future work in nanotechnology, indicating a potential benefit to taking the course.
  • There is a suggestion to review the course textbook, "Introduction to Quantum Mechanics" by David J. Griffiths, to assess personal preparedness and identify weak areas in the background knowledge.
  • One participant mentions the possibility of self-studying higher-level mathematics to compensate for the lack of formal coursework.
  • Concerns are raised about the quality of instruction and the availability of help for mathematical concepts that may be challenging.

Areas of Agreement / Disagreement

Participants express a mix of opinions regarding the necessity and feasibility of taking the Quantum Mechanics course. While some emphasize its importance for a career in nanotechnology, others highlight the potential challenges due to the participant's current mathematical preparation. No consensus is reached on whether the participant should enroll in the course.

Contextual Notes

Participants note limitations in the participant's mathematical background and the structure of their degree program, which does not offer higher-level mathematics courses. There is also mention of the need for foundational knowledge in physics that may not have been covered yet.

Hey,

I'm currently in my second year of an undergraduate degree in Nanotechnology. I have the option of do a 3rd year quantum mechanics subject. The problem is I have only done first year level mathematics and have not done classical mechanics (Although, I have done a second year Modern Physics subject and a vibrations and waves subject). I was just wondering if I should not take the subject because I won't have the mathematical background required to do well?

Any help will be much appreciated.
Thanks

What textbook does the QM course use, and what does "first year level mathematics" include in your system? I assume you're not in the USA.
 
For the physics part, you'll need an understanding of topics like angular momentum and central forces. In a second half of a year QM course, you'll probably need an understanding of Maxwell's equations in differental form, and particularly the vector potential.

On the math side, the vibrations and waves course will be useful if it included Fourier methods and simple boundary value problems, but you'll also need to know some vector calculus, some linear algebra and matrix algebra.

You might be able to make up deficiencies as you go along if you are not otherwise overloaded, but remember that QM is already a very intellectually challenging subject aside from much of the mathematical methods used.
 
I'm no expert, but won't QM be practically essential if you want to carry on working with nanotechnology after your degree?

The mathematics that I have done are: Algebra (With matrices), differential calculus, series and integral calculus. I'm from Australia. :)

The textbook for the subject is "Introduction to Quantum Mechanics" by David J. Griffiths.

I know right? Thats why I think I should be doing it.

@Daverz, We have done Fourier methods in the vibrations and waves. Should I attempt to learn the maths/physics over the summer before the subject begins?
 
Is this the program?

Or maybe one of the others listed here:

I think I'd wait until after you've had linear algebra and diff eqs and completed the Physics prereqs if you haven't already. Is there a scheduling reason for taking the QM course early?

You could also check out the text and see how far you can get in it.

How good is the professor? If you don't understand some math do you know someone who can help?

I don't have a choice of doing any higher level mathematics than the first year... So unless I do the mathematics myself, I won't learn it.

I'd start working through the course textbook so you can find out where your background feels weak. I'd say up through chapter 4 should give you a good idea.

Griffiths gives some recommendations for background reading in the preface to his book:
