You need to quote whoever it is you are responding too (as I have here) otherwise nobody has any idea who or what your reply is directed at.

The three consecutive replies from OP make it seem like he's talking to himself  :-DD

Let's start off with teaching you to use the forum quotation BB code.

Baby steps, baby steps ...

The 741 op amp was introduced to industry in 1968.  It hadn't filtered down by the time I graduated in '73.  In grad school I worked on digital design and avoided analog with a dedication.  Mostly because the math was a bit** on a slide rule.  The HP 35 calculator wasn't introduced until 1972 and I couldn't afford one until about 1976 when I finished grad school and bought an HP 45.  We did a lot of simplifications in those days simply because the math was untenable.  Large matrix problems weren't all that much fun.

Digital, in the early days of the microcomputer, was a lot more interesting.  With FPGAs, it still is!

I would have to go back to my books for your Field Theory problem and it isn't interesting to me.  It wasn't interesting when I took the class and it isn't interesting now.  What is interesting is whether to use a one, two or three process Finite State Machine.  Each has their good points and I usually choose to use the two process approach.  Other opinions vary...

You can look a Dave's video on magnetic shielding for the Field Theory problem.

I used the 741 in 1980 for the first time, programmed a Z80 in 1982, programmed a TMS320C25 in 1989 and love field theory. I've been programming FPGAs since 95 and still have one on my desk right now. I learned Field Theory from Haus and Melcher.

I learned several interesting tidbits here in EEVBlog, and contributed to several other threads.

As others have said, the University will not teach you everything about the intricacies of the trade and much less provide the knowledge across the board on incredibly diverse areas that members routinely contribute here.

Sorry that you are not pleased with your interactions around here, but it is far from such generalizations.
