All my life I've tried to learn beyond the basics of electronics, and invariably I've hit the same wall. Meanwhile some guys just seem to "have" whatever it takes to understand these things. Years ago I used to work in a qualification lab at one of the major computer mfrs, and I loved listening in to discussions between my boss (who was by all accounts a guru) and his peers. Electronics in its more esoteric and theoretical aspects resembles a religion.
No real point to this post, other than to give a hat's off to y'all.
