Best way to learn about any technical field is to have a keen curiosity on how things work, desire to understand the theory and experience.
I've been exposed to courses - I've taught myself far more in great debth just by reading manuals manuals, looking at schematics, forums where pros post, some experience doing stuff for myself.
only reason to go to school is if you need the certs to get a job. Otherwise there's so much stuff out there on the net (and to a lesser extent in libraries - can find textbooks) that school is a waste of money.
