Hi everybody, I'm working on a Solar Energy project and I'm a newbie in this field. Could you suggest some good intro books/articles and PV system simulation books? (I'm using MATLAB) Note that my major in university are Solid State Physics and Computational Physics so I will not hesitate to...

let's try these books Schaum's 3,000 Solved Problems in Physics https://tinyurl.com/y7mgtut6 Schaum's Outline of Applied Physics https://tinyurl.com/yawmdot9 Problems in General Physics https://tinyurl.com/y75cbrve

you want a fundamental book like Serway, Halliday, or you want to read a specific book on Mechanics, Electricity&Magnetism, Optics,...?

sorry, we cannot see the picture

I've just received an email from PF, that someone replied my post and said "Huang is rubbish"? Well, i know a lot of people on Amazon said that, but at least this book is helping me about Ising Model, my thesis topic :biggrin::biggrin::biggrin:

I'm reading these 4 books for my thesis

Hope he didn't mean to say the first one...:DD

This picture may answer your question "how does an overlapping and non-overlapping wavefunction look like?"

It's a quadratic equation with variable ##t##, so if you want to separate ##t## from the equation, it means that you are going to find the root of the equation https://en.wikipedia.org/wiki/Quadratic_equation

Hope it can help you :wink:

Hope this figure can help you :-p

But...the answer in the solution is a correct answer, just compare to the Cosine rule :eek: You wrote down the correct cosine rule, as above, but when you put ##E_{A}, E_{B}, E_{C}## into your calculation, I see that you put them in the wrong place

The wrong thing is your Cosine rule at the first line of your "relevant equation". Please check again :wink:

About the number 3/2, you can calculate it if you've learned Statistical Mechanics course :wink: Actually, I knew that E=(3/2)kT when I study Thermodynamics course, but we just admitted, I didn't know why we have it, until I studied Stat. mechanics :biggrin:

Oh you're welcome but don't say you're stupid. I think it's a conventional situation when we prove a formula/relation, we usually want to expand everything, substitute everything from everywhere to see the expected result at the end of the progression, but the result goes too far away that we...
