Socratus unlike others you have at least made efforts to read and understand. So lets see if I can get you a bit futher along.

Lubos Motl did a really good article on why quantum mechanics has to be complex and linear. It has some heavy mathematics but the mathematics is not essential to the understanding.

Read around the mathematics and see if you can follow the science logic of how and why QM works.

The last few paragraphs spell it out for you very neatly and concisely.

Feel free to ask about anything you don't get.

I believe in "Evil, Bad, Ungodly fantasy science and maths", so I am undoubtedly wrong to you.
