That's really a shame, since my perception is that you can understand quite a lot of "practical" electronics without understanding much more than Ohm's law and the "beginning" description of basic components. I mean, senior year of my EE program, we analyzed a 555 timer IC at the transistor level, but I don't think I see why it takes much training to understand it at the "logical block" level presented in most data sheets... Perhaps it's one of those "legacy educational" things; the Powers That Be are so intrenched in teaching EE in the old ways (calculus, physics, more calculus, etc) that no one has even tried to do it differently... Every once in a while you find someone who is "self- taught" and effective without that background. but it's rare...
