> I was taught the same in my Electrical Engineering degree! That's true. I'm not implying at all that in Engineering they do stuff the same way ham radios do, but sometimes we see Engineering building successfully upon certain phenomena, even though the comprehension of the underlying mechanisms is still evolving. A good example of that are the explanations for how an airplane wing works. It's been 20 years or so that the Coanda Effect is accepted as the explanation (afaik), but that didn't prevent engineers from building airplanes before that.
