Ohm's Law hasn't changed. As you point out, everything an EE learns
in school still applies, just with different packaging for the most
part. When our main design engineer graduated, DSP's didn't exist.
Now our product is loaded with them, and he designs the circuits and
writes the code. The rest of the circuitry is exactly what was taught
in school.
The writer's posit is wrong.
The writer has no clue what engineering is or the courses of study
taught to become one. Young's modulus hasn't changed but in the field
of structural mechanical engineering composite materials and
"engineered" components has certainly changed how structures, aircraft
and even automobiles are designed. In the general field of electrical
and electronics, digital communications has it's modern roots in Morse
Code and 8 bit Teletype systems. Nothing is really "new". Technical
advancements are mostly improvements of prior methods.
Harry cracks me up. I took a mismatch of electrical/electronics/facility
engineering courses over the years it took to get a basic degree. None
of it applied directly to what I ended up doing during
my working career but much of the math and physics involved were very
much related. For example, the principles of electromagnetic radiation
and energy transfer in the field of thin film optical coatings are
very similar to that of RF transmission systems. Same use of a Smith
chart, same basic principles except at a much, much shorter wavelength.
It was easier for me with a background in transmitter and radar systems
to get my head wrapped around thin films in optics than most mechanical
types.
