Physics Switching Careers for the Long Haul
What area of physics are you interested in? You could look into quantum computing, for example, where having a CS degree isn't necessarily a disadvantage. There are masters in quantum technology (upon which quantum computing or better yet quantum information is a subfield) such as in Munich*...- Irishdoug

I hate my vibration class (vent)
Have you emailed your professor and asked for your exam transcript back? And asked him to go through it with you? Has he got office hours? Even go to his office and knock in and tell him you are having trouble with the class!- Irishdoug

Cancellation of terms, Kittel (first edition) equation 6.4
Well what you have said sounds more reasonable. The integral is given as ##\int_{\-infty}^{\infty}## which is why I said what I did.- Irishdoug

Cancellation of terms, Kittel (first edition) equation 6.4
$$A_{average} = \frac{\int_{-\infty}^{\infty} A(p,q) \ e^{-\frac{E}{kT} }dp\,dq} {\int_{-\infty}^{\infty} e^{-\frac{E}{kT} }dp\,dq}\quad ?$$ Yes I meant this indeed. So I'm viewing it as follows: p = $$(p_{x1}, p_{y1}, p_{z1} ; p_{x2}, p_{y2}, p_{z2}... p_{xN}, p_{yN}...- Irishdoug

Cancellation of terms, Kittel (first edition) equation 6.4
Hi BvU. Thankyou for the response. I'm using Kittel's solid state book. Sorry I thought he only had that one. And yes I have the first edition (and the 7th!). I feel from a cursory glance he goes through the maths in a more understandable way in the first, at least in some sections. I am busy...- Irishdoug

Cancellation of terms, Kittel (first edition) equation 6.4
I'm happy I understand why the dq terms cancel out. So, $$E_{average} = U = \frac{\frac{1}{2M} \sum_{\alpha = 1}^{3N} p_{\alpha}^{2} \int_{-\infty}^{\infty} \Pi_{\beta = 1}^{3N} e^{\frac{-p_{\beta}^{2}}{2M k_{b}T} }dp}{\int_{-\infty}^{\infty} \Pi_{\beta = 1}^{3N} e^{\frac{-p_{\beta}^{2}}{2M...- Irishdoug

High School Quantum Entanglement information transmission idea to knock down....
Many entangled particle pairs are prepared with property A (1 or 0) at 99% probability of 1, and property B (1 or 0) at 1% probability of 1. I don't believe such a state would really be considered entangled.- Irishdoug

Lost in a physics career and willing to return
Just be aware in Scandinavia if you already have a masters then getting the government grant will not be an option as far as I know. So you will have to completely self-fund yourself. I'm 90% sure the above is correct but as ever best do your own research.- Irishdoug

Other I feel anxious when writing my first paper
As a native English speaker, this will unlikely be the case. It may well be that one will be able to tell you are not a native speaker however it is unlikely they will be confused. From the short paragraphs you've written here your English seems fine as does your grammar. So I wouldn't worry...- Irishdoug

Studying Where shall I start? (16 y/o wanting to become quantum physicist)
If you want a concise overview of the type of maths you will need, you can buy (or google for a free PDF!) Mathematical Methods in the Physical Sciences by Mary L. Boas. To me, it's a classic, and a nice broad, yet not too difficult book.- Irishdoug

Admissions Continuing formal education after an abrupt stop
Suggesting that the education system, and University you attended, is fundamentally racist makes it sound like you are trying to blame others for your own failures. As regards to other places to apply, have you tried Denmark? It isn't too difficult to get accepted once you have the minimum...- Irishdoug
