I've always enjoyed talking to electrical engineers. They have some of the best stories, and some of the best "banter". One "banter" line that explains somewhat why the digital H/W engineers didn't like the "analog world"... as an analog designer said, "Analog is that scary world between 1 and 0".
One funny story was from an Analog power supply design engineer. Back in the day they built prototype circuits in a "3D soldered elec component wire balls". This was simply to minimize stray reactances & give high resistance to limit coupling to circuit nodes. The engineer had it working great. Went for a snack (chocolate bar). After that it was operating strangely. Drove him to frustration. Closely inspecting the tight "circuit wire ball" he noticed a tiny piece of chocolate had fell into the rats nest, lodged itself, and changed the conductivity between two separate legs if the tiny axial resistors in the wire ball.
In a way, the electronics engineering world (especially high tech) has more dimensions & a lifetime of projects that would satisfy any appetite of curiosity. The downside is the stress.
You still in the field of your expertise?
Nope. When I graduated from the Air Force Academy the Air Force put me in an airplane. Not too much design work in that. By the time I got out the field had changed too much for me to work in it.
At the risk of dating myself, my field was optimal control (mostly math). The main tool I used for modeling potential solutions was an analog computer. It was much more accurate than my slide rule. Hand held calculators weren't out yet...
(Yes, my grand kids think I'm older than dirt...)
My senior project was designing the control systems to keep a satellite pointed directly at the sun with minimal use of fuel. They actually used it, although a lot more work by other people went into it before it went into space.
My engineering degree, heavy on math, gave me a running start on high tech "stuff". My first civilian job was assessing new product ideas and possible acquisitions for Chevron. I did the same thing for SOHIO before BP bought them.
