I read through that thread and found myself wanting to understand, any suggestion on a book or books that an electrical engineer would find accessible enough to dig through?

This is a vague question but my knowledge is vague.

Any suggestions are welcome, thanks.

Also, what sort of jobs do people with this sort of knowledge work in? Always probing for new opportunities.
