Sorry for the off-topic lead. I meant 50% teachers in my state in US that are actively teaching physics aren't certified to teach the subject. Not 50% of all teachers.
Yeah, not much recent stuff in intro college physics for non-physics majors but if you think of the following, which I cover, you'll find it is everywhere in electronics:
Simple harmonic oscillators - crystal oscillators, very tiny but very large modulus for MHz range oscillations that every device needs
Waves and music - you name it
Basic spring and capacitors - when micro-machined, it becomes accelerometers
Resistors and strain gauges
I also mention modern methods for measuring stuff, like pressure cell instead of u-tube barometer, thermistor instead of mercury thermometer (One student even stuck the wrong end of a mercury thermometer in the water since she's never seen one in her life LOL).
The list goes go.
The most recent physics would be covered in the 3rd semesters for physics, some ECE and chemistry students, called modern physics. That one does have quantum stuff, photoelectric effect, semiconductors, x-ray electron and neutron diffraction, duality and relativity etc.
