I'm beginning my education in quantum mechanics next semester and I'm not sure whether I should take Introduction to Analysis, which would cover "the real number system. Sequences, limits, and continuous functions in R and 'Rn'. The concept of a metric space. Uniform convergence, interchange of limit operations. Infinite series. Mean value theorem and applications. The Riemann integral" or Numerical Analysis, which would cover "programming for numerical calculations, round-off error, approximation and interpolation, numerical quadrature, and solution of ordinary differential equations. Practice on the computer." I'm going to talk to an advisor about it but I was curious what you guys thought.

For an undergraduate/introductory text, maybe using Griffiths' text, the first course (real analysis) is essential. I would read some complex analysis, too.

Definitely do the real analysis -- gives you a behind the scenes look at the math for QM.

If one looks at the text "Mathematics of Classical and Quantum Physics," by Frederick W. Byron, Jr. and Robert W. Fuller, it will give a good idea of the mathematics involved. The however is considered complementary to graduate-level physics texts.

depends on what your looking to do ...if your looking to do simulations...thatn numericals is better...but if your down right aiming for pure theory...analysis.

Here's another way to look at it.

When I was a student I took courses in both analysis and numerical analysis. In my opinion, numerical analysis is easier for someone to pick up on their own than is analysis if the persom starts fron (almost) scratch in both.

This is a very subjective opinion, and so is probably not true for everyone.

George
 

1. What is the difference between analysis and numerics in the context of quantum mechanics?

Analysis refers to the use of mathematical tools and techniques to study and understand the behavior of quantum systems. This includes solving equations and deriving analytical solutions. Numerics, on the other hand, involves using computational methods to simulate and model quantum systems. This can involve using algorithms and programming languages to solve complex equations and analyze data.

2. Why is a strong understanding of math necessary for studying quantum mechanics?

Mathematics is the language of science, and quantum mechanics is a highly mathematical field. Many of the concepts and theories in quantum mechanics involve complex mathematical equations and calculations. Without a strong foundation in math, it can be difficult to fully grasp and apply these concepts.

3. What are some of the specific mathematical concepts used in quantum mechanics?

Some of the key mathematical concepts used in quantum mechanics include linear algebra, differential equations, and complex analysis. Other important concepts include probability theory, Fourier transforms, and group theory.

4. Can quantum mechanics be understood without a deep understanding of math?

While it is possible to have a basic understanding of some of the concepts in quantum mechanics without a strong math background, a deeper understanding of the field requires a strong foundation in mathematics. Without a solid understanding of the mathematical principles underlying quantum mechanics, it can be difficult to fully understand and apply the theories and concepts.

5. How can I improve my math skills for studying quantum mechanics?

The best way to improve your math skills for studying quantum mechanics is to practice regularly and seek out resources such as textbooks, online courses, and tutoring. It can also be helpful to focus on developing a strong understanding of key mathematical concepts and their applications in quantum mechanics.
