Would like to help out my brother...
I have been trying t help my brother get better at school and just make him more interested. He is currently finishing up his first grade of high school.
I noticed that he is very gifted in mathematics and enjoys physics somewhat. So I was thinking of helping him prepare a bit for this, as he has told me he would like to study a bit ahead.
I was wondering what the best course of action would be for this. Since he should advance his knowledge of mathematics a lot more in order to understand Physics, I am in need of some help for which textbooks to use?
Thanks for any help, greatly appreciated.
