Hello.First i will introduce myself. I am 16 years Bulgarian boy and I am in math and geography school. My passions are electronics, math(and especially higher mathematics), physics(I now reading quantum physics for beginners by zbigniew ficek and one Bulgarian book about technical mechanics). Also I am interested in programming and robotics, couple of mouths ago I opened my own class for developing robots, where I am some kind of teacher(I had been sponsored by my school and I bought lego mindstroms(for those you have some knowleage about it, We don't use graphical IDE, but Python)arduino and a lot of servor, sensor, wires and so on). Finally some of my background interests are Linux and Penetration testing(White hat), computer communications.I know there are a lot of stuffs and it's hard to me to manage my time, but lets talk about, for what i come here, shall we. I really dont know from where to start with higher mathematics. In school we are on log's, and the leastest thing a read is about negative square root(imaginetion i²= -1 and the graphical representation).I want some help for finding the right way of starting with higher mathematics, and also there can be some physics realeted books, i won't regret it. Sorry if it's seems like complete mess.
